Calling T-Mobile from outside the US
T-Mobile says to dial +1-505-998-3793 from your mobile device to reach Customer Service from another country, free from a T-Mobile phone. It also warns that toll-free numbers such as 1-800 or 1-888 can't be guaranteed to work while abroad. If your own phone is lost or can't connect, call the 505 number from VoixCall as an ordinary paid call.
Common reasons people call from abroad:
- Phone lost or stolen abroad: suspend the line
- No service or roaming not working
- Unexpected international charges

What to have ready before you call
- The T-Mobile phone number on the account
- Your account PIN or security answer

How Much Does It Cost?

Your first call is free. After that you pay from prepaid credit, with no subscription. Recording adds $0.003/min. Rates as of 2026-10-06; see current rates for the US.
Record the call and keep the reference number
A call to T-Mobile usually ends with a case or reference number and a promise about what happens next. After a long hold, in a second language, it's easy to miss a digit.
Switch on Record on the VoixCall dialer before you call ($0.003/min). If you've also turned on "Record and transcribe my calls" in Settings (web or the iPhone/Android app), about a minute after you hang up Call History shows a short summary, the reference numbers that were said (each with a Copy button), what each side agreed to do next, and the full transcript, for $0.02/min.
Recording is off by default. T-Mobile hears a short recording notice when the call connects, and only you can see your recordings and transcripts. Speech-to-text can mis-hear fast numbers, so check important digits against the recording. Recording laws differ by country. How call transcripts work →
