T-Mobile for Business Review

T-Mobile for Business sells three phone plans. CoreMobile covers the basics, ProMobile adds much more premium and hotspot data plus Threat Protect security, and SuperMobile adds unlimited premium data, T-Satellite texting and a nationwide 5G network slice for business traffic. All three include unlimited talk, text and data, a 5-year price guarantee on talk, text and 5G data, and a $0 early termination fee.

The prices are built for teams. With AutoPay and the third-line-free offer, six lines cost $125 a month on CoreMobile, $200 on ProMobile and $250 on SuperMobile, plus taxes and fees. A single line is $65, $85 or $100 on T-Mobile's price labels. If you're a one-person business, Metro, Mint or a consumer T-Mobile plan on the same network usually costs less.

Pricing: What You'll Actually Pay

T-Mobile's Broadband Facts labels give the monthly price for the whole account by line count. The labels state that these prices don't include AutoPay or other discounts:

Lines	CoreMobile	ProMobile	SuperMobile
1 line	$65	$85	$100
2 lines	$100	$150	$170
3 lines	$120	$180	$210
4 lines	$140	$210	$250
5 lines	$160	$240	$290
6 lines	$150	$240	$300
8 lines	$200	$320	$400
Each line, 9+	+$25	+$40	+$50

T-Mobile advertises the six-line price with AutoPay on lines 1 to 5 and the third line free: $125 (CoreMobile), $200 (ProMobile) and $250 (SuperMobile). AutoPay takes up to $5 off each of the first five lines (a $25 maximum) and needs a bank account or debit card. The third line free is a monthly bill credit for new accounts that activate at least three voice lines, one free line per account.

On top of the plan price: a $35 device connection charge per line, a regulatory programs and telco recovery fee of $4.49 per line on the label (the plan fine print says up to $5.49), federal and local surcharges of typically $0.36 to $4.79 per line, and taxes.

What You Get, and What You Don't

Add Business Internet for $35

Any business voice line unlocks T-Mobile 5G Business Internet for $35 a month, paid as $35 in monthly bill credits, with the same 5-year price guarantee on the internet data. T-Mobile also offers up to $800 toward your old internet provider's early termination fee. Both offers are limited-time and need a credit check.

How It Compares on the Same Network

For a one- or two-person business, T-Mobile's consumer and prepaid brands use the same towers:

Plan	Price	What to know
T-Mobile ProMobile (business)	$85 for 1 line (label)	Lines owned by the business, Threat Protect, 200GB hotspot
T-Mobile Experience More	$85/mo with AutoPay	Consumer flagship with Netflix and travel perks
Metro by T-Mobile $30	$30/mo	Prepaid, taxes included, 10GB hotspot
Mint Mobile Unlimited	$30/mo on 12 months	Prepaid, pay up front, owned by T-Mobile

A business plan earns its price when you have several employees: the numbers stay with the company when someone leaves, and the per-line price falls with each line up to six. For one line, the prepaid options cost less than half as much. See all of them on our Metro plans and Mint Mobile plans pages.

Who Should Choose T-Mobile for Business

• Teams of three or more: third line free and the falling per-line price make six lines cost $21 to $42 a line.
• Field staff who tether laptops: ProMobile's 200GB hotspot or SuperMobile's 300GB.
• Crews who work outside cell coverage: SuperMobile includes T-Satellite texting.
• Businesses that want a fixed price: the 5-year guarantee covers talk, text and 5G data.

Who Should Skip It

• Sole owners with one line: Metro or Mint costs a fraction of the single-line price.
• Teams where T-Mobile's signal is weak: check coverage at every site and route first.
• Anyone who wants all-in pricing: taxes and fees are extra on every plan.

How to Switch

1. Check coverage at your office and wherever staff work. T-Mobile for Business lists a free network trial; read its terms first.
2. Count your lines: the price table above changes a lot between one, three and six lines.
3. Get each line's account number and transfer PIN from your current carrier.
4. Order online for up to 12 lines, or go through T-Mobile's business sales team for more.
5. Keep the old service active until each number has ported.
