Trick for using AT&T SIM cards

Legacy Legacy AirPrime modules

Hi all,

I am using a Q2698 (WIP library) with an AT&T SIM and am able to get a PPP session and open a TCP socket (can see it on Wireshark at the other end). But when I send from either end through the socket nothing happens. The code works fine with other SIM cards in other countries. Are there any tricks to using AT&T SIM cards with the Q2698?

Using an Open-AT application, or AT Commands from an external host :question:

What error/status results are you getting :question:

Does the AT&T SIM work for other devices :question:

Sorry I really bad at getting the right info in forum posts.

OpenAT application with calls to WIP library.

None on the module end, the write to TCP command responds with a successful send of x bytes, the read event never fires. On the PC at the other end Wireshark sees the open connection and bytes being sent out to the module, but there are a number retry errors.

Supposedly yes, but I am not there to verify.
