I just put an At&t sim card in m At&t Bold. The phone is still locked on this network.

When i turn it on it says gets full signal then straight to SOS. I can see the data icons flashing though, dont know if there is some activity going on which is making it go on SOS.

Thanks

Try a battery pull.

I have

Are you in an area with a good signal?

Does the SIM work in another ATT device?

And please update your profile with the device you are currently using. Helps when you have problems and fail to mention the device type.

Ye i found out it was the ATT service. Thanks
