Ok… I’ve got a GL-X750. Put in AT&T SIM. To be clear- I’m fairly technical, but not when it comes to this device…
So, I ‘tooled around’ with the settings and got it to connect.
This means that:
I changed the IMEI to match the IMEI registered to the SIM.
This is a Data-only plan, so I read I need to go in and set the APN to broadband.
I do this by clicking on Manual.
Then I can connect.
…And the connection stays up for a while and drops.
I tried the things in this post:
AT&T Network Fix Solution
Where do I begin to troubleshoot this? What more info should I share?
I’ve been looking in the logs, online… Am at a loss.
