The best business phone plans in 2026
Five plans from T-Mobile, Verizon, AT&T and US Mobile, compared on what you actually pay per line.
For most teams of three or more, T-Mobile ProMobile is the best value at $34 a line for six lines, with a 5-year price guarantee and $35 business internet when you add a line. On the tightest budget, T-Mobile CoreMobile is $21 a line. For one or two lines, US Mobile for Business is $30 a line with taxes included. Pay more for Verizon or AT&T only if their signal is clearly better where you work.

Everything we recommend
T-Mobile for Business ProMobile
The best balance of price and features for most small teams. At six lines it costs $200 a month with AutoPay ($34 a line), locks the price of talk, text and data for five years, and includes Threat Protect. Add T-Mobile 5G Business Internet for $35 a month with any voice line. See every plan, fee and add-on in our T-Mobile business phone plans review.
One line is $85 a month, so the value comes from adding lines. Every new line has a one-time $35 device connection charge.
T-Mobile for Business CoreMobile
The lowest per-line price we found from a major carrier: $125 a month for six lines with AutoPay. It covers unlimited talk, text and data with the same five-year price guarantee as ProMobile.
After 50GB in a month, data can slow when the network is busy, and hotspot is only 5GB at full speed. Fine for calls, email and maps; tight for field staff who tether laptops.
US Mobile for Business
For a solo owner or a two-person shop, US Mobile undercuts the big carriers, which charge $65 or more for a single line. You pick the network that works best at your site, and the price includes taxes and fees. Business Premium is $49 a month with more hotspot and international data. Read our US Mobile for Business review.
US Mobile is an MVNO, so it has no stores and no dedicated business account rep.
Verizon Business Unlimited
Worth the higher price if Verizon is the only strong signal at your business or on your routes. Per-line prices fall as you add lines; Verizon shows the exact multi-line total in its plan builder. Verizon also discounts some business phone plans when you have Verizon Business Fios internet.
Advertised prices exclude Verizon's Economic Adjustment Charge, a per-line fee that is not a tax.
AT&T Business Unlimited Advanced 3.0
A good fit for teams that need AT&T's network or plan to pair lines with AT&T Business Fiber. Standard 3.0 is about $30 a line at four lines with 5GB of premium data, and Ultimate 3.0 adds unlimited hotspot data (slowed after 500GB).
AT&T's lowest online prices often depend on buying a phone on a 36-month installment plan. Bring-your-own-phone lines can cost more.

Prices with AutoPay, plus taxes and fees unless marked. *US Mobile includes taxes and fees. AT&T prices are for four lines, the line count AT&T advertises. Checked on carrier plan pages Oct 19, 2026.
What you pay beyond the advertised price
Every carrier's headline price assumes AutoPay and a certain number of lines. Budget for these on top:
- Connection or activation fees. T-Mobile charges $35 per line once. AT&T and Verizon may charge activation fees too.
- Monthly carrier fees. T-Mobile's regulatory and telco recovery fee is up to $4.49 per line. Verizon adds an Economic Adjustment Charge. These are set by the carrier, not the government.
- Taxes and surcharges. Government taxes and surcharges vary by city and can add several dollars per line. US Mobile is the exception: its business prices include them.
- Line-count pricing. T-Mobile's third line free and AT&T's four-line pricing only apply at those counts. Price your real number of lines.
Which plan fits your business
The right plan depends on how many lines you need, how much your team uses data away from Wi-Fi, and which network is strongest where you work. Start with the case that sounds most like your business:
- Solo owner or two people: US Mobile for Business. Big-carrier single lines start at $65 or more.
- Three to twelve lines, mostly calls and email: T-Mobile CoreMobile.
- Field staff, heavy data or hotspot use: T-Mobile ProMobile or AT&T Business Unlimited Advanced 3.0.
- Weak T-Mobile signal at your site or on your routes: Verizon or AT&T. Check each carrier's coverage map at your address first.
- You also need internet: compare the bundle. T-Mobile Business Internet is $35 a month with a voice line; see our business internet rankings and backup internet options.
Business plan or personal plan?
A business plan puts the lines under your company, so the account survives when an employee leaves and you can move numbers between staff. It also unlocks business-only perks: T-Mobile's 5-year price guarantee on its business plans, AT&T ActiveArmor security on every business line, and bundle pricing with business internet.
For one line, a personal plan or an MVNO is often cheaper. Once you have three or more employees on company phones, business plans usually win on price per line and on control.
What each carrier includes for business
| Carrier | Security | Extras | Internet bundle |
|---|---|---|---|
| T-Mobile | Scam Shield on all plans; Threat Protect on ProMobile and SuperMobile ($1.99/line on CoreMobile) | T-Satellite texting on SuperMobile ($10/mo add-on on CoreMobile); network slice on SuperMobile | 5G Business Internet $35/mo with any voice line |
| AT&T | ActiveArmor mobile security on all business plans | AT&T Turbo for Business on Advanced 3.0 and up; Day Pass days included on Ultimate 3.0 | Business Fiber, ordered separately |
| Verizon | Call Filter | 5G Ultra Wideband in covered areas | Discount on some phone plans with Business Fios |
| US Mobile | Basic spam blocking | Choose the network per line | None |
From carrier plan pages, Oct 19, 2026. Features vary by plan tier.
Phone and internet together
If you also need internet at the office, price the bundle, not just the phone lines. T-Mobile is the simplest: any business voice line drops T-Mobile 5G Business Internet to $35 a month with a 5-year price guarantee, and T-Mobile pays up to $800 toward your old provider's early termination fee. That makes T-Mobile a strong backup line even if your main connection is cable or fiber.
Verizon gives a discount on some business phone plans when you also have Verizon Business Fios. AT&T sells AT&T Business Fiber separately. For every option at your address, start with our business internet rankings.
Switching offers to ask about
- T-Mobile: up to $600 per line when you switch, via 20 monthly bill credits. It requires a port-in and a plan of at least $85 a month with AutoPay, with your own phone or one bought at full price.
- T-Mobile third line free: new accounts with at least three voice lines get one free line on eligible plans, for as long as you keep the plan.
- AT&T and Verizon: both run device and switching promotions that change often and are usually tied to 36-month installment plans. Ask for the total cost over three years, with and without the phone deal.
Bill-credit offers stop if you cancel the line or change plans before the credits finish, so don't switch for the credit alone.
How to switch your business lines
You can keep your business numbers when you change carriers, and most ports finish within a day. Doing these steps in order helps you avoid missed calls during the move:
- Check coverage first. Test the new carrier at your business and on your usual routes. T-Mobile and Verizon both offer network trials.
- Get your port-out details from your current carrier: account number, port-out PIN and the billing address on file.
- Check that phones are paid off and unlocked, or budget for the remaining device balance.
- Have your business details ready: legal business name, EIN or SSN for sole proprietors, and an authorized contact.
- Don't cancel the old account yourself. Porting the numbers closes those lines; cancelling first can lose the numbers.
- Move one line first, confirm calls, texts and voicemail work, then move the rest.
Common mistakes
- Comparing single-line prices when you'll have five lines, or six-line prices when you'll have two.
- Forgetting AutoPay. T-Mobile's advertised prices need it, and the discount requires a bank account or debit card.
- Picking the cheapest plan for staff who tether laptops. CoreMobile's 5GB high-speed hotspot runs out fast.
- Ignoring per-line fees. A $4.49 monthly fee across ten lines is about $540 a year.
What business customers say
J.D. Power surveys thousands of business decision-makers each year about their wireless carriers. In the 2026 U.S. Business Wireless Satisfaction Study (October 2026), T-Mobile ranked highest among large enterprises (768 out of 1,000), and Verizon ranked highest among medium businesses (747).
For small businesses with fewer than 20 employees, the latest published ranking is from the 2025 study: AT&T (688), Verizon (686) and T-Mobile (681) finished within seven points of each other. That spread is small enough that price and coverage at your address should decide.
Among all postpaid customers, business and personal, T-Mobile ranked highest of the three national networks for the third survey in a row in the 2026 U.S. Wireless Carrier Satisfaction Study (Volume 2, July 2026), scoring 636 against a segment average of 612.
On network quality, the 2026 U.S. Wireless Network Quality Performance Study (Volume 2, July 2026) found Verizon and T-Mobile neck and neck. Verizon had the fewest problems in the Mid-Atlantic, North Central and Southeast regions, T-Mobile led the Southwest, and the two tied in the Northeast and West. The gaps were one or two problems per 100 uses, which is why testing at your own address matters more than a national winner.
On managing your account online, the 2026 U.S. Telecom Digital Experience Study placed T-Mobile third among wireless carriers (tied with Metro by T-Mobile at 672), behind Mint Mobile and Spectrum Mobile.
How we picked
We compared the current small-business plans on each carrier's own plan pages on October 19, 2026, and ranked them on the monthly price per line at the line counts most small businesses buy, premium data before slowdowns, hotspot data, price guarantees and extra fees. Coverage varies by street, so check each carrier's map at your address before you switch. For office phone systems rather than cell lines, see our business VoIP guide.
Others we considered
T-Mobile SuperMobile ($42 a line for six lines) adds unlimited premium data, 300GB of hotspot and T-Satellite texting. Worth it for teams that work outside cell coverage. AT&T Business Unlimited Ultimate 3.0 adds unlimited hotspot data, but costs more per line. Cable-company mobile plans from Comcast Business and Spectrum Business require their internet service, so they only make sense if you already have it.
Questions
Is a business phone plan cheaper than a personal plan?
Often, once you have several lines. T-Mobile CoreMobile drops to $21 a line at six lines with AutoPay, and AT&T Business Unlimited Standard 3.0 is about $30 a line at four or more. For one line, business and personal prices are close, and an MVNO like US Mobile is usually cheapest.
Do business phone plans require a contract?
T-Mobile's business plans are month to month with a $0 early termination fee. Verizon and AT&T also sell month-to-month business lines, but device promotions are usually tied to 24- or 36-month installment plans, and leaving early ends the credits.
What fees are not in the advertised price?
T-Mobile adds a $35 device connection charge per line and a regulatory and telco recovery fee of up to $4.49 per line, plus taxes. Verizon adds an Economic Adjustment Charge. AT&T may charge an activation fee. US Mobile's business prices include taxes and fees.
Can I bundle business internet with phone lines?
Yes. T-Mobile 5G Business Internet is $35 a month with any business voice line, with a 5-year price guarantee. Verizon gives a discount on some business phone plans when you also have Business Fios internet.
How many lines do I need to get the low prices?
Most carriers hit their lowest per-line price at four to six lines. T-Mobile's third-line-free offer applies to new accounts with at least three voice lines, which is why its advertised prices assume six lines.
Can a sole proprietor get a business phone plan?
Usually yes. Carriers generally accept an EIN or, for sole proprietors, a Social Security number. Some perks and credit limits differ for very small accounts.
What is premium data?
Data that gets priority when a tower is busy. After you use your premium allowance, speeds can slow during congestion until the next bill cycle. T-Mobile SuperMobile and AT&T Advanced 3.0 and up have unlimited premium data.
Do business plans work in Canada and Mexico?
The major carriers include talk and text in Canada and Mexico on these plans, with a high-speed data allowance (5GB on T-Mobile's business plans). For other countries, T-Mobile includes texting and slower data, and AT&T Ultimate 3.0 includes some International Day Pass days.
