How to Cancel T-Mobile in 2026

Updated February 2026 • 7 min read

T-Mobile has no service contracts — but they have device payment plans that act like one. Cancel your line and the remaining phone balance is due immediately, plus you lose any promotional credits. Here is how to navigate it.

Cancel Wireless

1. Call 1-800-937-8997 or dial 611 from your T-Mobile phone
2. Or visit a T-Mobile store in person
3. If keeping your number: port to new carrier first (auto-cancels the T-Mobile line)
4. If not keeping number: tell the rep you want to cancel
5. They will inform you of any device payment balance
6. Get confirmation and note your final bill date

The Device Payment Trap

Cancel T-Mobile Home Internet

T-Mobile Home Internet ($50/month) has no contract. Call 1-800-937-8997 to cancel. Return the 5G Gateway within 30 days to avoid a $370 device charge (if rented/financed). If you own it outright, no return needed.

Number Porting (Keep Your Number)

To keep your phone number:

1. Sign up with your new carrier and request to port your number
2. Provide your T-Mobile account number and PIN
3. The port takes 1-3 hours for wireless
4. Once ported, your T-Mobile line automatically cancels
5. Do NOT cancel T-Mobile before porting — you will lose your number

Cheaper Alternatives (Same Network)

• Mint Mobile: $15-30/month (T-Mobile network), 3/6/12-month prepaid
• Tello: $10-29/month (T-Mobile network), custom plans
• Google Fi: $20-65/month (T-Mobile + US Cellular)
• Metro by T-Mobile: $30-60/month (T-Mobile subsidiary, prepaid)
• US Mobile: $25-44/month (T-Mobile or Verizon network)

The Bottom Line

T-Mobile has no service contracts but device payments create a similar lock-in. Check your device balance before canceling — leaving early on a "free phone" deal can cost hundreds. Port your number first, then the cancellation happens automatically. MVNOs on the same T-Mobile network cost half as much.
