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 device. In some cases, cellular
radio frequencies can disrupt the performance
of other electronic equipment. If you have
questions about the interaction between your
device and any other piece of electronic
equipment, ask the equipment manufacturer.
Drive safely
When you are driving, T-Mobile encourages
you to use your device in a safe and sensible
manner. Here are a few tips:
• Assess road conditions before answering
your device. 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.
