Troubleshooting

How do I know when my account is ready to register for data serv-

ices?

Once your account is ready for you to register for data services, you will

see a “Welcome” message on your screen. If the Welcome message

doesn’t appear on your device within 48 hours after registering, contact

T-Mobile Customer Care department.

In order to comply with airline regulations, how can I temporarily dis-

able wireless connectivity when traveling?

Remember to switch to “Airplane Mode” during aircraft takeoff and

landing. To turn off wireless connectivity (to comply with FAA regulations)

follow these instructions:
1 From the Jump screen, press

, and select Airplane Mode > Turn

Wireless Off.

2 Your device is now offline. Confirm offline status by looking at the title

bar; the radio icon and “OFF” should blink alternately.

Even without wireless connectivity, you can still access the device

applications and read email messages that already been downloaded.

However, you will not be able to send or receive messages until you enable

wireless connectivity again.

How can I protect my device from damage?

The best way to protect your device is to carry it with the display closed.

You risk damaging your device if you do not protect the display. Also,

water–even in small amounts or in the form of steam–can seriously damage

your device and charger, so keep your device dry and away from potential

water sources.
