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.
