When inserting the sim card, I get a signal but no internet. When checking, it says “No internet access”
I’m using the EM7511 module.
What are the return of the following?
Ati3
At!gstatus?
At!selrat?
At!band?
At!impref?
Sorry for being a bit late. Here is each command result.

at!gstatus? shows it is not attached to network and there is no signal
did you connect antenna?
Are you using ATT SIM card?
BTW, I saw your FW version is quite old, you might consider to try the newer firmware:

Thank you for replying. I’m using a Verizon sim card. The antennas are connected.
Verizon works with its specific firmware. When testing ATT, it does not work even with the most up to date firmware for it. I have cellular signal bars, but it says “No internet access”.

AT!GSTATUS? shows it has been attached to ATT network.
What is the return of the following?
AT!entercnd="A710"
AT!usbcomp=?
AT!USBCOMP?
I want to check whether it has been set to enable MBIM interface instead of RMNET interface,
BTW, are you testing in linux PC or Windows PC?
Did you set correctly in host platform for the APN?
I’m using windows. The APN should be correct.
AT!entercnd=“A710”
OK
