Solution

I pressed the power key but nothing happened.

Make sure that the battery is fully charged. See the user guide for more information.

Insert SIM Card appears on the display even though I have already inserted the SIM card.

Make sure that you have inserted the Subscriber Identity Module (SIM) card correctly. See the user guide for more information.

The device indicates that my PIN is blocked. How do I unblock the device?

The SIM card will block itself if you have typed the PIN incorrectly three times. To unblock it, you must type the unblocking key (PUK). Contact T-Mobile Customer Care to get the unblock key.

My device displays the name of another carrier.

This will occur if you are roaming outside of T-Mobile coverage area. Visit Personal Coverage Check to verify your coverage area.

Make sure the ringer on your device is not turned off or in vibrate mode.

I tried to place a call and heard an alternating high and low tone.

Your call did not reach the system correctly. You may have dialed the number too soon after turning on the device. Wait until the device displays T-Mobile before making a call. If you still cannot place the call, verify that you are using the 10-digit number and try again. Contact T-Mobile Customer Care if the problem continues.
