Just picked up a new Cubot One. When I first put my AT&T sim card in, it seemed to be working fine, connected to the 3G and whatnot. Some calls came through, a bunch of picture messages came through just fine, but I cant send and receive texts from certain people.

When I send a text to certain people, it immediately says 'message not sent' with a red triangle. No other details about the error.

I tried to play with the APN but it had no effect.

Anybody offer some assistance? It would be sweet to not have to buy another phone
