AT&T Customers:

"Using this device on the AT&T network may require calling AT&T to register the IMEI. In the event their system loses that registration, you may get degraded performance or no service at all and you may want to request that they install a monitor in their system to ensure your IMEI remains in their system. Contact AT&T at 866-344-6217."     ~Bob Greenberg, CEO Rfinder
