Your T-Mobile bill is higher than you were quoted.

You signed up for one price and the wireless bill came in higher. That gap almost always comes from a handful of lines on the bill. Here's where to look, what T-Mobile's own pages say, and how long you have to dispute it.

The lines to check on your T-Mobile bill

• The Regulatory Programs & Telco Recovery Fee: $5.49 per voice line per month. It's T-Mobile's own charge, and quotes made before October 12, 2026 may show the old amount. source
• The Device Connection Charge, a one-time fee per line on activation or upgrade. source
• Promo and trade-in credits "can take up to two billing cycles to appear." If the first bill is missing it, you should see two credits on the second. source
• The AutoPay discount needs a bank account, debit card or T-Mobile Visa. Other credit cards, Apple Pay and Google Pay don't count, and paying early with one removes the discount on your next bill. source

How long you have to dispute

T-Mobile's terms say you must notify them in writing within 60 days of first receiving the disputed bill, or you can't take it to arbitration or court. Accepting a credit counts as a full release. source

What to do, in order

1. Get your proof together: the order confirmation, chat transcript or screenshot of the quote, and your first two or three bills.
2. Call billing and point to the exact line that doesn't match the quote. Ask them to fix it and note the account. Write down the date, the rep's name and the ticket number.
3. Put it in writing inside the dispute window above.
4. Still stuck? File a free FCC complaint at fcc.gov/complaints or 1-888-225-5322. The FCC says the provider must respond in writing within 30 days. source
