Safety Tips
Consider device compatibility
If you have a pacemaker or hearing aid, check
with your doctor to make sure it is safe for you to
use a cell phone. In some cases, cellular radio
frequencies can disrupt the performance of other
electronic equipment. If you have questions about
the interaction between your phone and any other
piece of electronic equipment, ask the equipment
manufacturer.
Drive safely
When you are driving, T-Mobile encourages you to
use your phone in a safe and sensible manner. Here
are a few tips:
• Assess road conditions before answering your
phone. Your safety is more important than any
call.
• Prepare your hands-free headset, if you have one,
or turn on your speakerphone, before you
start moving.
• Keep your phone close. If it rings and you
discover it’s in the back seat, do NOT crawl over
the seat to answer it while driving.
