GL-X3000 TTL change

Newbie help request:

I figured out the AT commands for IMEI repair. Now trying to figure out - How do I update change the TTL when using a SIM?

Carriers of interest are AT&T, Verizon, T-Mobile, and Visible if you have recommendations on what value it should be for this configuration it would be much appreciated! Thanks!

Normally, you don’t need to set TTL, if you want to set TTL, please use our V4.3.1 firmware(GL.iNet download center), and then set the TTL in the web interface, please refer to the pictures below.

Why do you want to change IMEI? As the routers comes with a valid IMEI which is in their database.

Thanks! Firmware update seemed to fix the TTL setting.

I know this is old ... new purchase Jun2025, and firmware is updated to current ... The TTL settting in "Cellular Settings" does not work. I can add to firewall custom rules and it does work.
FWIW - with no firewall custom rules the default TTL is 113.
