Public Safety / 9-1-1

T-Mobile USA is committed to a partnership with Public Safety to provide the best possible 9-1-1 service for our subscribers and roaming customers in times of emergency.

T-Mobile's public education efforts

T-Mobile is committed to educating our customers about mobile phones and 9-1-1. On T‑ and in materials sent directly to customers we also address issues such as accidental calls to 9-1-1. The State of Washington's 9-1-1 Office created these brochures: 

Accidental 9-1-1 calls

What's Your Location

Remember, when calling 9-1-1 during an emergency:

Stay calm and speak clearly.

Do not hang up until the 9-1-1 call taker has obtained all of the information that is needed.

Since you are calling from a wireless phone, your call may be disconnected if the signal is lost. Be sure to call 9-1-1 back if you are cut off. If you are driving, consider pulling off the road and stopping the vehicle to complete the 9-1-1 call.

Your 9-1-1 call may need to be transferred to another agency.
