In most cases, you can set the desired APN using the ATAN command. In some cases, you may need to set it via bypass mode by entering command mode (+++) and setting the ATAP command to a value of 5 and writing it to flash. Then rebooting the module. You can use the following process:
+++
ok
ATAP5 <CR>
ok
ATWR<CR>
ok
ATFR<FR>
ok
Once the module resets, and you have given it a min or two, you can issue an AT to verify you are in command mode.
AT<CR>
ok
To set the APN, the following command would be issued:
AT+CGDCONT= 3, "IPV4V6", "desired APN value" <CR>
ok
Once set, issue the +++ and set the ATAP back to 0
+++
ok
ATAP0<CR>
ok
ATWR<CR>
ok
ATCN<CR>
ok
The module will reboot and come up using the new APN value you set above.
*Note, using bypass mode should be done by those with knowledge of the Telit commands or by guided instruction from Digi Technical Support under a Expert or Professional Support Agreement.
