Best Business Phone Plans for Small Businesses in 2026: A Complete Guide

The cheapest way to get a professional small business phone system in November 2026 is a VoIP plan at about $15 per user per month on annual billing, and the cheapest way to get actual cellular lines is a multi-line plan, where T-Mobile’s CoreMobile works out to $21 per line at six lines with AutoPay. Which one you need depends on whether your team talks from a laptop and a phone app, or from a phone in a truck with no wifi. This guide prices both, line by line, from each company’s own pages.

I have run Ecommerce Paradise and location-independent stores since 2013, and a real phone number has been part of every one of them. For high ticket stores it matters even more, because buyers spending thousands of dollars often want to call first.

Disclosure: some links below are affiliate links, which means I may earn a commission at no extra cost to you. That includes my Quo, Dialpad, Grasshopper, Nextiva and Verizon Business links. The commission does not set the order of this guide, and where a cheaper option is the better answer I say so.

Prices are as of November 2026, in US dollars, before taxes and fees unless stated, and they change often. Check each vendor’s page before you buy. T-Mobile’s business pages would not load for me during the latest check, so its figures are from the earlier read and are marked below. This is general information, not legal or tax advice.

Small business phone plans at a glance, as of November 2026

This table puts the entry prices side by side. The VoIP rows are per user per month. The cellular rows are per line per month, and the conditions in the last column change the number a lot, so read them.

Option	Type	Entry price	Billing basis and conditions
Quo (formerly OpenPhone) Starter	VoIP app	$15 annual, $19 monthly	One number per user, US and Canada calling and texting
Nextiva NEXT Core	VoIP	$15 annual, $23 monthly	100 business texts per user
Dialpad Standard	VoIP	$15 annual, $27 monthly	Pro is $25 annual and $35 monthly, 14 day free trial
RingCentral Core	VoIP	$20 annual, $30 monthly	Annual price is the same in the 1 to 5 and 6 to 100 user brackets, 25 SMS per user per month
Grasshopper	Virtual number	From $14 a month	Homepage figure, billing basis not confirmed, plan table not shown to me, US and Canada only
T-Mobile CoreMobile	Cellular	$21 per line at 6 lines with AutoPay	$65 for one line before AutoPay
Verizon My Biz Plan	Cellular	$65 per line	$70 without Auto Pay and paper-free billing, one line
AT&T Business Unlimited	Cellular	$20 to $55 per line at 4 lines	Discounted for 12 months with conditions, list prices run $40 to $85

If you only read one line: for a solo operator or a remote team, a VoIP phone system costs less and does more. For a team that works in the field, you probably need cellular lines, and the multi-line math is where the money is.

VoIP phone system for small business or cell phone plan?

This choice matters more than which brand you pick, so I will define both terms plainly.

A cellular business plan is a SIM card in a phone. Calls run over a carrier’s mobile network, so they work anywhere that carrier has signal. You pay per line, and the per-line price depends on how many lines you buy.

A VoIP phone system runs calls over the internet. You get a business number that rings in an app on your phone, laptop or desk phone, and the plan adds business features such as a phone menu, shared inboxes and call routing. If your store is run from a laptop and a phone, this is usually the better fit, and in my experience it is also the cheaper one. You do need internet, which I come back to in the reliability section.

There is also a third option many solo sellers actually need, which is just a second number on the phone they already carry. I cover that in my guide to getting a second phone number for your business, and it is often all a one-person store requires.

Best VoIP phone systems for small business

Quo (formerly OpenPhone): the plan I use for high ticket stores

Quo is the new name for OpenPhone, and the Quo homepage still lists the product as “Quo (formerly OpenPhone)” in its title. It gives each user a business number in an app, with calling and texting in the US and Canada, voicemail transcripts and shared numbers, so a virtual assistant can see calls and texts alongside you.

The prices on quo.com/pricing are per user per month. Starter is $15 on annual billing or $19 monthly. Business is $23 annual or $33 monthly. Scale is $35 annual or $47 monthly. The page lists the annual totals as $180, $276 and $420 per user per year.

What changes between tiers is useful to know before you pay for the wrong one. Starter limits shared numbers to 10 paid users and tasks to 10 open tasks. Business adds AI call summaries and transcripts, group calling, call transfers, phone menus, HubSpot and Salesforce integrations, analytics and automatic call recording. Scale adds AI call tags, onboarding support and priority support. Extra phone numbers are $5 a month each, and porting an existing number is free.

The AI receptionist is called Sona, and it is included on every plan, but it runs on credits. The page lists one call as 100 credits, a free tier of 1,000 credits (10 calls) and paid credit tiers from $25 a month for 4,000 credits up to $199 for 60,000. If you plan to have an AI answer a lot of calls, price the credits as well as the seat. My Quo pricing breakdown goes through every plan and add-on.

Best for: solo operators and small remote teams that want a business number, shared numbers and texting for the lowest published seat price.

RingCentral: the larger unified communications option

RingCentral sells RingEX plans for teams that want calls, meetings and chat in one app. On its business phone pricing page, the 1 to 5 user bracket shows Core at $20 per user per month on annual billing and $30 monthly, Advanced at $25 annual and $35 monthly, and Ultra at $35 annual and $45 monthly. The 6 to 100 user bracket shows the same annual prices of $20, $25 and $35. I did not check monthly prices there or the 100 or more bracket, so a larger team should check the bracket that applies to them.

Core includes unlimited domestic calling, on-demand call recording, 100 toll-free minutes, 25 SMS per user per month and HD meetings for up to 300 participants. Advanced adds CRM integrations, multiple sites, core reporting, 1,000 toll-free minutes and 100 SMS per user per month. The AI Receptionist is an add-on on Core and Advanced, and the page shows it as starting at $39 without saying how that is billed. That is a real cost on top of the seat, so ask for it in writing.

If you are weighing RingCentral against other options, my RingCentral alternatives roundup compares seven of them.

Best for: teams of 5 to 50 who want phone, video and chat from one vendor and are willing to pay more for it.

Nextiva: a cheap annual rate with a big monthly jump

Nextiva prices its small business plans per user per month. On nextiva.com/pricing, NEXT Core is $15 on annual billing against $23 monthly, NEXT Engage is $25 annual against $50 monthly, and NEXT Scale is $75, with no monthly price shown for Scale.

Core includes unlimited voice and video, 100 business text messages per user, skills-based routing, shared team and personal inboxes, a basic CRM and ticketing system, and 50 AI transcriptions, summaries and answer-assist conversations. Toll-free numbers and virtual fax are add-ons, and live chat and single sign-on are not on Core. The gap between $15 and $23 is why I always tell people to price the monthly figure if they do not want a one-year commitment.

Best for: small teams that will commit to a year and want routing and a light CRM in the same plan.

Dialpad: transcripts in the base plan, with a big monthly jump

Dialpad lists Standard at $15 per user per month on annual billing and $27 monthly, and Pro at $25 annual and $35 monthly, with Enterprise on a contact-us basis. Standard includes HD calls and meetings, real-time transcripts, call summaries and built-in messaging. Pro adds key CRM integrations, 24/7 support and multi-office management. There is a 14 day free trial. The page also warns that regional pricing and currency can change your actual price.

I wrote up the product in my Dialpad review, and that is the post to read if AI call summaries are what you are shopping for.

Best for: teams that want transcripts and summaries built into the base plan.

Grasshopper: a simple virtual number

Grasshopper is a business phone number service. Its homepage says plans start from $14 a month and offers a 7 day free trial. I could not confirm from the homepage whether the $14 is billed annually or whether the trial needs a card.

That is all I can confirm. When I opened the pricing page in a browser that Grasshopper treated as outside the US and Canada, it showed a notice that the service is available only in those two countries, and the plan table did not load. So I have no plan names, number counts or per-plan prices to quote. Anyone who needs a number while living abroad should check availability before building a plan around it. My Grasshopper pricing guide covers what I could verify on plans and year-one cost.

Best for: US or Canada based solo sellers who want a simple number.

Other VoIP names worth knowing

Ooma is another small business VoIP name, and I reviewed it in my Ooma review. If you want a wider comparison across many providers on price, emergency calling and number porting, my best VoIP services roundup covers eight.

If your problem is a support team handling many customer calls rather than one owner’s phone, the plans above are the wrong shape, and my guide to business phone systems for ecommerce support teams is the better starting point.

Best cell phone plans for small business

Most of the people who search for small business phone plans are really asking about cellular lines. Here is what each carrier shows on its own pages. Cellular pricing is full of conditions, and the headline number is rarely the one you pay.

T-Mobile Business: the clearest multi-line ladder

On t-mobile.com/business/plans, the headline prices, which I could not reopen in the latest check and which come from the earlier read, are for six lines with AutoPay: CoreMobile is $21 per line ($125 a month for the account), ProMobile is $34 per line ($200) and SuperMobile is $42 per line ($250). T-Mobile’s footnote says that is pricing for six lines plus taxes and fees, with AutoPay applying to lines one to five and the third line free on lines three to twelve.

The standard prices before AutoPay are listed by line count. For CoreMobile, one line is $65, two are $100, three are $120, four are $140, five are $160 and six are $150. For SuperMobile, one line is $100 and six lines are $300. T-Mobile says these standard prices are not an introductory rate and do not need a yearly contract. Hotspot data is 5 GB high speed on CoreMobile, 200 GB on ProMobile and 300 GB on SuperMobile.

Fees sit on top of this. The page lists a regulatory programs and telecom recovery fee of $4.49 per line, federal and local surcharges that it says are typically $0.36 to $4.79 per line, and a $35 per line device connection charge. It also states a 5 year price guarantee on talk, text and 5G data, excluding taxes and fees. The free third line promotion needs at least three voice lines on a new account.

I compare the two big carriers plan by plan in my Verizon Business versus T-Mobile Business guide.

Best for: teams of three to twelve lines that can use AutoPay and want a published price at every line count.

Verizon Business: My Biz Plan and priced add-ons

Verizon Business lists My Biz Plan as its base mobile plan. On its plan page it is $65 per line per month with Auto Pay and paper-free billing, or $70 without them, excluding taxes, fees and an Economic Adjustment Charge. The base includes unlimited talk, text and 5G and 4G LTE data, 5 GB of mobile hotspot, Call Filter, and Canada and Mexico talk, text and data.

The page does not show multi-line prices. It says the base price drops as you add lines and that five or more lines get the lowest base price, so you need a quote for a team. It does show add-on prices: a 50 GB mobile hotspot is $5 a month, Premium Network Experience is $10, International Connectivity is $10, and International Long Distance Calling is $5 per region.

My Verizon Business pricing breakdown walks through the structure.

If Verizon is not the right fit, my Verizon Business alternatives guide sorts options by what you need the line to do.

Best for: businesses where network reliability matters more than the lowest price.

AT&T Business: prices depend on four lines and discounts

The AT&T Business wireless plans page lists Unlimited Standard 3.0, Advanced 3.0, Premium 3.0 and Ultimate 3.0. The list prices are $40, $50, $60 and $85 per line. The page then shows lower figures of $25, $20, $30 and $55 per line when you get 4 lines, for 12 months, after AutoPay, paperless billing and a limited-time promotion. Some of the savings also require a new line or a smartphone bought on installment, and taxes and fees are extra.

All plans include unlimited talk, text and data in the US, Canada and Mexico. I am not quoting hotspot allowances for AT&T, because the page contradicts itself: one section lists unlimited hotspot on Ultimate and the FAQ says its plans do not offer unlimited hotspot data. Ask AT&T which applies before you buy for hotspot use.

Best for: four-line teams that qualify for the discounts and want AT&T coverage.

What a small business phone bill looks like

Here is the math for three team sizes, using only the figures above. I did not include taxes, fees, add-ons or hardware.

Team	Quo Starter	Nextiva Core	RingCentral Core	T-Mobile CoreMobile
1 person	$15 annual, $19 monthly	$15 annual, $23 monthly	$20 annual, $30 monthly	$65 standard
3 people	$45 annual, $57 monthly	$45 annual, $69 monthly	$60 annual, $90 monthly	$120 standard
6 people	$90 annual, $114 monthly	$90 annual, $138 monthly	$120 annual	$125 with AutoPay, $150 standard

Two things stand out. First, the monthly-billed VoIP price runs 27 to 53 percent above the annual one on the Quo, Nextiva and RingCentral entry plans, and 80 percent above it on Dialpad Standard, so a quote that does not say which basis it uses is not a quote. Second, at one to three people a cellular line costs several times more than a VoIP seat, which makes sense because you are buying a phone connection and a data plan rather than a business phone app. The gap narrows at six lines with AutoPay.

The right comparison depends on what you already pay. If your team already carries phones on a personal plan, a VoIP seat adds a business number without adding a line, and that is usually the cheapest way to separate work from personal calls.

Business texting and the registration cost

If you plan to text customers from a business number, check what registration costs. Texting from a business number can involve carrier registration. Quo’s pricing page lists a registration charge through The Campaign Registry: a one-time $19.50 review fee plus a messaging fee of $1.50 to $3 a month depending on use case, and it lists automated texts sent through its API, Zapier or Make at 1 cent per message segment. Other vendors have their own fees, and RingCentral’s Core plan caps SMS at 25 per user per month, so count your texts before you pick a tier.

Emergency calling and outages on VoIP

This is the downside of VoIP that sales pages skip. The FCC’s VoIP and 911 guide says VoIP service may not work during a power outage or when the internet connection fails or becomes overloaded. It says providers must collect your physical address before service starts, and that you should update it each time you change location, because 911 may otherwise not reach the right center.

For a store owner, that has two practical consequences. Register the address where you actually work, and keep a cell phone as a backup for emergencies. If you travel and run your number from an app, update the address in the provider’s settings when you move. Set up call forwarding to a mobile number for outages too, which most phone systems let you configure, so confirm yours does.

How to choose a business phone plan

Start with who answers. If one person answers, you need a number and voicemail, not a call center. If a virtual assistant also takes calls, you need shared access to the number, which is where a Quo seat earns its price.

Count your texts. Included text allowances differ widely, from 25 per user per month on RingCentral Core to 100 on Nextiva Core. If texting customers is half your use, that number decides the plan.

Price the add-ons. AI receptionists, extra numbers, toll-free numbers and fax are priced separately on most of these plans. Quo’s extra numbers are $5 a month each, Nextiva lists toll-free and fax as add-ons, and RingCentral’s AI Receptionist starts at $39.

Choose billing on purpose. The annual price is the one in the ad. Decide whether you will still run this store in twelve months before you pick it.

Check coverage and country. Cellular needs coverage where you work, and Grasshopper is limited to the US and Canada. If you live abroad, a VoIP app that works anywhere with internet is usually the answer.

Check porting. Quo says porting is free. Confirm the process and any fee before you cancel your old service, because a number you have used for years is a business asset.

What to pick if you run a high ticket store

This section is my opinion, not a vendor claim. A store that sells a few expensive items a week gets fewer calls than a support-heavy store, but each call matters, because a buyer about to spend thousands wants to hear a person. In my experience, that points to a VoIP seat with a shared number and after-hours handling, rather than a cellular plan, and it is the setup I would build first.

The number is one trust signal among several. My guide to how high ticket dropshipping works explains why order size changes how much buyers need reassurance. If you are still choosing a category, my high ticket niches list shows where bigger orders live.

Suppliers also call, and some will only talk to a business line. I explain that in how to get a business phone number suppliers will accept.

The rest of that process is in my step by step supplier guide. Your phone bill is also a recurring business expense, so set up the entity first. My business formation checklist covers it, and your accountant can tell you how your expenses are treated.

What I could not verify

Grasshopper plans. Not shown. The pricing page said the service is for the US and Canada and did not load the plan table for me, so I only have the homepage’s “from $14 a month” and 7 day trial. Check grasshopper.com/pricing from inside the US or Canada.

T-Mobile business prices. T-Mobile’s business pages returned an access denied error to my browser in the latest check, so the figures in this guide come from the earlier read and were not re-confirmed. Check the page before you buy.

RingCentral monthly prices for 6 or more users. Not shown in what I read. I confirmed the annual prices for the 6 to 100 bracket only, so check the bracket that fits your headcount.

Verizon multi-line prices. Not shown. Verizon says the base price drops with more lines, so ask for a quote.

AT&T hotspot allowances. The page contradicts itself, so I am not quoting them.

Frequently Asked Questions About Business Phone Plans

What is the cheapest small business phone system?
As of November 2026, the lowest published seat prices I found are $15 per user per month on annual billing for Quo Starter, Nextiva NEXT Core and Dialpad Standard. On monthly billing Quo is $19 against Nextiva’s $23 and Dialpad’s $27, and Grasshopper’s homepage says plans start from $14 a month. Prices change, so check each page.

Is a VoIP phone system good for a small business?
Yes for most office-based and remote teams, because it adds business features at a lower seat price than a cellular line. The tradeoff is that VoIP depends on internet and power, and the FCC says it may not work during an outage. Keep a mobile phone as a backup and register your emergency address.

How much are business cell phone plans per line?
It depends on the line count and discounts. T-Mobile’s CoreMobile is $65 for one line and $21 per line at six lines with AutoPay. Verizon’s My Biz Plan is $65 per line with Auto Pay and paper-free billing, or $70 without. AT&T shows $20 to $55 per line at four lines for 12 months with conditions.

Can I keep my phone number when I switch?
Usually yes. Quo says porting is free. Confirm the timing and any fee with the new provider before you cancel the old service.

Do I need a separate business phone line?
Not always. A VoIP app gives you a business number on the phone you already carry, so you do not need a second device. Cellular lines make sense when staff need their own phones for work.

Bottom Line

For a solo operator or a remote team, a VoIP seat is the better value, and Quo’s published $15 annual and $19 monthly Starter prices are the easiest numbers to plan around. For a field team, cellular is the right tool, and T-Mobile’s six-line pricing is the clearest. Whichever you pick, compare the billing basis, count your texts and price the add-ons before you decide.

This is general information, not legal or tax advice. Plans and fees change, so confirm the details on each provider’s page as of the day you buy.
