Frequently Asked Questions

My phone says “unregistered SIM or SIM unavailable.” What do I do?

Generally this means that the phone has either timed out with the current tower or received a bad update over the air. In many cases this is not a huge deal. Try these two things:

1. Turn the phone off for about thirty seconds and then turn it back on. Many times this will re-register the phone in the system and correct the problem.

2. Take the battery and the SIM card out of the phone. Leave the phone powered off for 30 seconds. Like the above method it will cause the phone to re-register and correct the problem.

If neither option works, please bring the unit in so that we can evaluate the phone and the SIM card.

How can I tell how many minutes that I have used in the billing cycle?

AT&T Mobility has two great ways of doing this. Both of these options are based on AT&T’s billing records. Give either one a try:

1. Logon to wireless.att.com and login to your account.
2. From your handset dial *646# and then press send. It will be displayed in a free text message on your handset.

My phone is malfunctioning and it’s less than a year old?

AT&T Mobility backs all of their handsets with a one year parts and labor warranty. You can have your phone replaced simply by calling the Exchange By Mail Center at (800) 801-1101.

They will take the info on your current phone and the problems that you are experiencing. They may try to troubleshoot it a little bit over the phone. Once it is determined that the device is indeed defective AT&T will send you a replacement device along with a prepaid package for the defective item.

It is extremely important to determine that your phone is not malfunctioning due to liquid exposure or physical damage as these are not covered by your warranty.
