How to Keep a US Phone Number While Living Abroad: The Real Sequence

Start with the thing that ruins this plan for most people, because if I put it at the bottom you will read the bottom too late.

Tello, Mint Mobile and US Mobile all require the line to be activated and first used inside the United States. Not preferably. Required, and published in their own words. Tello says its service cannot be initially activated outside of the US, that to activate an eSIM you must be physically located within the United States, and that international roaming only works if the line has been used in the USA before roaming is enabled. Porting a number in also has to happen from inside the country. Mint frames the whole abroad case as conditional on the plan having been activated in the US. US Mobile’s terms say a US Mobile line must first be activated and used within the United States. Google Fi tells you to activate and use the service in the US for at least one day before using it abroad.

Which means this is a before you leave job, or a next trip home job. It is not a this afternoon job if you are already sitting in another country, and almost nobody writing about this tells you that, because almost nobody writing about it has had to do it from the wrong side of an ocean.

I run a high ticket store from Bali. The US number is not sentimental, it is operational: suppliers ring it to verify dealer applications, and the answer rate on those calls influences whether the application gets approved. My bank texts it. My payment processor texts it. So this is the sequence I would follow, in order, with the traps named where they actually occur.

Disclosure, before the first paid link. The Tello links in this guide are affiliate links and this site is paid when somebody signs up, up to ten dollars a signup. Google Fi and Quo are also monetised here, so those are not neutral references either. Mint Mobile, US Mobile, Ultra Mobile, NumberBarn, Tracfone and Google Voice pay this site nothing at all, and at least two of them beat Tello on price. I would rather you knew the shape of my incentives before you took a single instruction from me.

Step One: Decide What The Number Has To Do

Everything downstream depends on this and people skip it. There are three distinct jobs and they have different answers, different prices and different failure modes.

Job one, hold the number. You want it to remain yours. Old contacts can still reach it. A plain text code turns up occasionally. You are not making calls on it and you are not using its data. This is the cheapest job and the easiest to satisfy.

Job two, receive bank and processor codes reliably. This is the job that breaks businesses when it fails, and it is a different question from price, because it turns on number class and on each sender’s own delivery policy rather than on how much you pay. Our guide to which US number actually receives bank and processor verification codes deals with that question properly, including the part where the rule everyone cites turns out to have been withdrawn.

Job three, answer supplier calls. A human being at a distributor dials the number on your dealer application and expects a person. That requires working inbound voice at a time of day that overlaps with American business hours, which is a scheduling problem as much as a telecoms one.

Write down which of the three you need. If it is only job one, you have cheap options and you can stop reading at the parking section. If it is jobs two and three, you need a real wireless line with data on it, and the rest of this guide is for you.

Step Two: The Activation Gate, In Detail

Here is what the gate actually means in practice, because “activate in the US” is vaguer than it sounds.

You need to be physically in the United States, on a US network, and you need to actually use the line before you go. Make a call on it. Send a text on it. Turning the SIM on and immediately flying out is not the same thing as having used the line, and the roaming condition is specifically that the line has been used in the USA before you enable roaming.

If you are taking the eSIM route, the location requirement bites harder, because Tello states plainly that eSIM activation will not work if you are abroad. There are also device exclusions: Tello’s eSIM excludes Chinese market iPhones and the Pixel 3 and Pixel 3a, and no complete device compatibility list is published, so check your specific handset rather than assuming. Before any of this, run your US address through the coverage checker, because Tello does publish a ZIP code coverage tool and a line that works badly where your family lives is a line you cannot test.

Tello will not tell you whose network you are checking. It describes the network as America’s largest, fastest and most reliable, and says its agreement does not permit it to publicly use the partner’s name in its marketing. I am not going to name it from memory either, because a guess is worth nothing to you and Tello has not published it. Our full review of Tello covers that refusal and what else the company does and does not commit to.

So the practical sequence is: order while you are in the US or before you land, activate in the US, use the line for a few days on American soil, toggle international roaming on before you leave, and only then fly.

Step Three: Port The Old Number Or Take A New One

This decision is harder than it looks, and the order of operations is counterintuitive.

Porting has one rule people get wrong. You cannot port your number until your new service is fully active. So the sequence is: buy the plan, activate it, get a working line with a temporary number, and only then submit the number transfer request for your old number. People try to port first and find the form will not accept them. The port also has to be done from inside the United States, which folds it into the same trip.

Tello does not publish a port in fee. Not a zero, not a figure. It is simply not published, so budget for the possibility and ask before you submit. For comparison, NumberBarn charges $5 per number to port in and waives it on the Park annual plan, and Mint’s port in is free from Mint’s side with most transfers completing within hours, up to 48 hours, and landlines taking up to five business days.

When to port. Port if the old number is already sitting on your bank records, your processor records, your supplier applications and your customers’ phones. Changing it means updating every one of those, and every update is a chance to lock yourself out of something. Porting is the conservative move.

When to take a new number instead. Take a new one if the old number is entangled with a carrier contract you want out of, if it is a number you have given to every telemarketer since 2011, or if you want a clean separation between a personal line and the business line that goes on dealer applications. What a supplier reviewer actually looks at when they see that number on your application is its own subject, and our guide to getting a business phone number suppliers will accept is the authority on it, so I am not going to duplicate that here.

The hybrid nobody mentions. Port the old number into parking and take a new number for the line. NumberBarn parks a number at $2.99 per month per number, forwards at $6.99, and port away is free if you later change your mind. That keeps your history alive for pennies while your new line does the work. It is only sensible if the parked number does not need to receive verification codes, because NumberBarn publishes a named list of senders whose codes do not reach its wireline numbers.

Step Four: Set Up Wi-Fi Calling Before You Leave, Including The E911 Address

Wi-Fi calling is the mechanism that makes this whole arrangement work. Tello’s own words are that Wi-Fi calling and text is a great way to stay connected when cell signals are weak or when you are travelling abroad, with minutes deducted from the monthly plan balance. And the sentence this entire cluster is built on.

“Once Wi-Fi Calling is active, you can receive One-Time Passwords (OTPs) and verification texts from your bank even if you are outside the US.”

Tello also publishes that Wi-Fi calling still works even if international roaming is activated, which matters because you will want both switched on.

Register the E911 address. This is the step people skip and it is not optional: Tello lists E911 address registration as a prerequisite for Wi-Fi calling. The emergency services system needs a physical address associated with the line because a Wi-Fi call has no cell tower to locate you by. Do it in your phone’s settings while you are still in the country, with an address you actually have a relationship with, because you will not want to be debugging a settings menu from a different time zone.

Then test it properly. Turn cellular data off, leave the phone on Wi-Fi only, and make a real call and receive a real text. Better still, trigger an actual verification code from one of your critical accounts. A code that arrived while you were on a US cell network proves nothing about the same code arriving over house Wi-Fi somewhere else.

Three caveats Tello publishes about Wi-Fi calling, all of which have bitten people. First, some public, office and hotel networks block Wi-Fi calling traffic, which Tello says is outside its control, so a coworking space or hotel can silently break your line. Second, if your Wi-Fi signal drops even for a second, the phone may jump to a roaming cellular connection and start spending your Pay As You Go credit. Third, picture messages do not work over Wi-Fi at all, which is the subject of the next step.

And configure roaming as the backstop. Tello publishes international roaming in more than 200 countries and territories, but you have to toggle International Roaming on, and separately toggle Pay as You Go Data on if you want data. Rates outside Europe are five cents a minute for voice, one cent per text and one cent per megabyte of data, all charged against your Pay As You Go balance. There is a promotional free roaming offer in Europe that is valid until 30 September 2026, and I am mentioning the date in the same breath because after that Tello says roaming charges come exclusively from Pay As You Go balances, so do not choose a carrier on the strength of a promotion that is about to end.

Whether your specific country is covered and at what rate is, for many destinations, not published. Tello does not publish a per country list or rate table, so Indonesia, to pick the one I care about, is neither confirmed nor excluded. Ask support in writing for your country before you depend on the roaming leg.

Step Five: Understand The MMS And Link Problem

This is the trap that catches people who did everything else right, and it is the single most useful thing in this guide after the activation gate.

Tello’s own configurator, on the no data plans, carries this warning.

“Are you sure you don’t need Data? Remember that Data is required to send or receive an MMS. Any text message that includes a file (like a picture, video, emoji, or a website link) turns into an MMS and requires Data.”

Read the parenthesis again. A website link. Not just a photo, a link. A great many account security and verification messages contain a link, and the moment one does, it is an MMS rather than an SMS.

Now stack Tello’s second published statement on top: while standard texts work over Wi-Fi, picture messages do not.

Put those together and you get the actual consequence, which nobody advertises. On the famous $5 no data plan, an MMS has no data to arrive on. And over a Wi-Fi calling setup abroad, MMS does not arrive at all regardless of your plan. So the $5 tier is perfectly good for holding a number and for receiving plain text codes, and it is the wrong thing to bet your store’s account access on.

The fix is cheap. Tello’s configurator prices 2 GB with 300 minutes and unlimited text at $8 per month, and the Starter plan gives you that same 2 GB plus unlimited talk and text for $10. Three dollars above the five dollar no data price buys you a plan that can actually receive a picture message on a cellular connection, and five dollars above it buys Starter with unlimited talk as well. Our breakdown of Tello’s price ladder shows why one of the $8 combinations is strictly worse than the $10 plan and should never be bought.

One more thing that is not a fallback, in case you were hoping. The My Tello app does not rescue you here. Tello publishes that you cannot receive calls or send and receive texts through the app. It manages the account. It is not a second inbox.

Step Six: What To Do If You Are Already Abroad With No US Line

This is the case the rest of the internet ignores, and it is the most common email I get. You are already living somewhere else. Your old US line lapsed or you cancelled it. You now need a US number and every guide you read assumes you are standing in Ohio.

Here is the honest position. Tello is not available to you today. Neither is Mint. Neither is US Mobile. All three require in country activation and there is no workaround I am willing to publish, because the ones people suggest involve either lying about your location or relying on a friend to activate a line in your name, and I am not going to recommend either.

What you can actually do, in order of usefulness.

First, salvage what you still control. If your old US number is still alive on any carrier, even on an expensive plan, do not let it lapse while you sort this out. If it is alive but you want to stop paying for it, port it into parking. NumberBarn accepts a port in from abroad at $5 per number and parks it at $2.99 per month, with no requirement to be anywhere in particular, which is why it is on this list at all.

Second, stand up a stopgap that does not need US activation. Basic Google Voice is $0 for personal use on a personal Gmail account and can be set up from anywhere. Use it for old contacts, for services that are not your money and for anything low stakes. Do not use it as your bank’s contact number, because Google itself says some websites, such as banks or subscription services, will not send text messages to Google Voice numbers, and that in those cases you may need your mobile carrier number. Google also reclaims numbers for inactivity with a 45 day recovery window and does not publish the inactivity threshold, so it is a stopgap and not a foundation.

Third, move everything you can off SMS entirely. This is the highest value action available to somebody in this situation and it costs nothing. For every bank, processor and platform that offers an authenticator app or a hardware key, switch to it now. Those accounts then stop caring what phone number you hold or where you are, which shrinks the problem down to the handful of institutions that only do SMS.

Fourth, plan the real fix around your next entry into the United States. Not a vague intention, a booked date. Order the SIM to an address you can receive post at, activate it on day one of the trip, use it for the whole visit, register the E911 address, toggle roaming on, and port your old number in while you are there. Half a day of admin during a trip you were taking anyway. Our checklist for moving abroad has the rest of the pre departure admin that belongs in the same afternoon.

Fifth, and this is the one people resist: if a US number is genuinely load bearing for your business and you have no US trip on the horizon, then that is a business risk with a date on it, and it deserves a real decision rather than hope. Either book the trip, or restructure which accounts depend on SMS, or accept the exposure knowingly. Pretending it will sort itself out is how people end up locked out of a payout account in the week they most need it.

And keep the geography question separate from the number question, because they get conflated constantly. Whether your login gets flagged for the country your traffic exits from has nothing to do with whether a text reaches your number, and we handled that side in our guide to running a store without tripping account security locks. If what you actually need is a local number for local services in the country you live in, rather than a US number for US services, that is the mirror image of this problem and our review of Airhub as a local destination number covers it.

Step Seven: Keeping The Number Alive, And The Two Cliffs

Once the line exists, the only way to lose the number is to let it lapse. Tello publishes no requirement to reconnect to a US network periodically, which is a genuinely useful absence: number loss is tied to payment, not to geography. Google Fi ties a consequence to time spent abroad and US Mobile ties one to consecutive days out of the country. Tello does not. That difference is real and it is checkable, and our Tello versus Google Fi comparison lays out exactly what Google’s timeline does and does not do.

There are two ways to hold the line and they fail very differently.

With an active monthly plan. Plans renew automatically every 30 days. If a payment fails and the plan lapses, Tello gives a 12 day grace period before the number expires, with a reminder email seven days before. Credit does not expire while a plan is active. Twelve days is enough time to notice and fix a dead card, which is the entire argument for staying on a plan rather than on credit.

On Pay As You Go with no plan. This is where people lose numbers, and Tello’s wording is blunt.

“If you DON’T have a monthly plan: Your credit expires 90 days after you buy it. If it expires, your service is disconnected and your phone number is deleted permanently.”

Deleted permanently. Tello also says it cannot bring back a number once it has expired. The number expiry page frames the same rule as credit expiring three months after purchase with the number staying active for a further seven days. Either way, a Pay As You Go balance is a countdown clock, and if you forget to top up for one quarter you do not lose service, you lose the number, and with it every account that used it for verification.

So the practical rule is simple: stay on a plan. The cheapest plan that holds a number is $5 per month and Tello markets exactly that, keeping your number for five dollars a month while abroad. Sixty dollars a year to remove a permanent deletion risk from your business is not a close call.

A couple of supporting details. Pay As You Go top up denominations are published at $20, $30, $40 and $50, and data needs a balance above fifty cents. There is a documentation contradiction here worth knowing: one Tello help page says a minimum $5 Pay As You Go credit is required to turn roaming on, while no $5 top up is actually offered. Both statements are live. And a genuine oddity: roaming data is published at one cent per megabyte while domestic Pay As You Go data is two cents per megabyte, which means data costs less abroad than at home. I am reporting that as published rather than explaining it, because Tello has not explained it.

There is also no formal pause or suspend feature published. Downgrading to the $5 tier is the published low cost way to hold a line you are not using. Upgrades and downgrades are free and can be done at any time, there is no contract, early termination is listed at $0, and one time purchase fees are listed as none on the Broadband Facts label, although a help page separately says a new line setup may incur a one time setup fee depending on your plan. Those two statements contradict each other and I cannot resolve which applies to your order. Taxes are extra and vary by location.

The Contradiction You Should Know Before You Build On Any Of This

I am not going to sell you a sequence without telling you the risk sitting underneath it, because it is the single real one and it is in Tello’s own paperwork.

Tello’s Terms say all Tello services must be used within the US and all orders must have a valid US address for tax purposes. That sits directly against a Tello landing page titled “Keep Your US Phone Number While Abroad”, a promo page offering to keep your number for five dollars a month when abroad, Wi-Fi calling described as a way to stay connected when travelling abroad, and roaming in more than 200 countries. Tello’s Terms appear to prohibit the exact use its marketing sells.

Whether “used within the US” is a tax nexus statement or a genuine usage restriction is ambiguous as written, and I am not going to resolve it, because I cannot and because a confident answer from me would be worth nothing. What I will tell you is what to do about it: if this line is load bearing for your business, ask Tello support in writing whether permanent use from outside the US is permitted, and keep the reply.

And for balance, Tello is not uniquely awkward here. Google Fi’s Terms say the services are offered only to residents of the United States, must be primarily used in the United States, and are not intended for extended international use, and Google reserves the right to suspend the account, terminate service or limit roaming for excessive off network usage. US Mobile says its plan is not intended for extended or permanent use outside the United States. Mint is the one that publishes no day limit and no return requirement at all, and Mint pays this site nothing, which is worth stating in a guide whose links pay us. Our Tello versus Mint Mobile head to head puts those terms side by side.

The Half Day Checklist For The Trip Home

If you take one thing from this guide, take this list, and do it on a trip you were already taking.

Check coverage at the US address you will be using. Order the SIM or eSIM to an address where you can receive post. Activate on arrival, not on departure day. Make a real call and send a real text on the line. Register the E911 address. Turn Wi-Fi calling on and test it with cellular data switched off. Submit the number transfer for your old number once the new line is fully active. Toggle international roaming on, and Pay as You Go data on if you want data abroad. Put a top up on the Pay As You Go balance so a Wi-Fi drop does not strand you. Update the number on every bank, processor, platform and supplier record, one at a time, confirming each one as you go. Trigger a genuine verification code on each critical account. Move every account that offers an authenticator app off SMS while you are at it. Then set a calendar reminder for the card expiry date on the payment method, because a lapsed card is the most boring way to lose a phone number.

If you are choosing between carriers rather than following a sequence, our ranking of plans for keeping a US phone number while living abroad sorts them by published cost, published limits and whether US activation is required. If you want the field organised by job rather than by logo, our breakdown of Tello alternatives does that instead.

And if you are setting up the rival that also pays us, we have a walkthrough of how to set up a Google Fi line, which is worth reading alongside our correction to the Fi timeline rather than on its own.

Where The Phone Line Sits In The Business

A phone plan is trivial next to the margin on one high ticket order, which is why I would rather you spent the afternoon on our list of high ticket niches worth building in than on carrier comparisons.

If the model is new to you, the unit economics are what justify all this admin in the first place. Our explainer on what high ticket dropshipping actually is covers why one approved supplier relationship outweighs a thousand small orders.

Supplier acquisition is the exact point where the phone number stops being a nicety, because the verification step is a person dialling the number on your application during American business hours. Our step by step guide to finding high ticket suppliers shows where in that process the call lands.

The entity comes before the phone line, because dealer applications ask for one and real suppliers verify it exists. Our walkthrough of business formation for high ticket dropshipping explains what to file and why the state you choose matters.

My stack is deliberately dull. The storefront runs on Shopify and always has. The company filing went through Bizee because it was quick and inexpensive.

Liability cover matters the day a supplier asks for a certificate of insurance and not a moment before, and mine is with Hiscox for that reason. The banking side has its own set of traps when you live abroad, which we cover in our guide to keeping a US bank account open from outside the country.

If assembling all of this yourself sounds like the wrong use of a year, we build and launch the whole operation through our done for you high ticket store build service.

Frequently Asked Questions

Can I set up a US phone line while I am already living abroad?

Not with Tello, Mint Mobile or US Mobile, all of which require the line to be activated and first used inside the United States, and Tello states that eSIM activation will not work if you are abroad. What you can do from abroad is park or forward a number you already control, or set up Basic Google Voice at no cost as a stopgap, and plan the real setup around your next trip into the country.

Do I have to return to the United States periodically to keep the number?

Tello publishes no such requirement, and that absence is worth knowing. Losing the number is tied to a plan or credit lapse rather than to where you are: a plan lapse gives a 12 day grace period, while Pay As You Go credit with no plan expires 90 days after purchase and then the number is deleted permanently.

Should I port my old number or take a new one?

Port it if it is already recorded with your bank, your payment processor, your suppliers and your customers, because changing it means updating all of them and every update is a chance to lock yourself out. Take a new number if you want a clean business line or if the old one is tangled up with a carrier you are leaving. Either way, the new service has to be fully active before a port request will be accepted, and the port has to be done from inside the United States.

What is the E911 address and do I really need to register it?

It is the physical address the emergency services system associates with your line, and Tello lists registering it as a prerequisite for Wi-Fi calling. A Wi-Fi call has no cell tower to locate you by, which is why the address has to be supplied manually. Set it while you are still in the country rather than from a different time zone.

Will my bank’s verification text arrive on the cheapest plan?

A plain text code, yes. A text containing a website link, no, because Tello’s own configurator says any message with a file or a link becomes a picture message and requires data, and Tello separately publishes that picture messages do not work over Wi-Fi. Pay for a tier with data, and keep a second route into anything critical.

What happens if the hotel or coworking Wi-Fi blocks the call?

It sometimes does, and Tello says so, noting that some public, office and hotel networks block Wi-Fi calling traffic and that this is outside its control. Tello also warns that if the Wi-Fi signal drops even for a second the phone may jump to a roaming cellular connection and start spending Pay As You Go credit, so keep a balance on the account.

How much does roaming cost outside Europe?

Tello publishes five cents a minute for voice, one cent per text and one cent per megabyte of data, charged against your Pay As You Go balance, with International Roaming and Pay as You Go Data both needing to be toggled on. There is a free roaming promotion in Europe valid until 30 September 2026, after which Tello says roaming charges come exclusively from Pay As You Go balances, so it is not a reason to pick a carrier.

Can I call my suppliers and my family from the line for free?

Tello publishes free calls to more than 60 countries with every plan, with the minutes coming out of your plan’s own balance rather than a separate allowance, and says it does not matter whether you are in New York or Paris when you place the call. Mexico and the United Kingdom are on the free list. Indonesia and the Philippines are not, and calls to destinations off the list bill from Pay As You Go credit.
