I’ve tried the 2 different SIM cards from different providers (both tested in a phone) using both Auto API and operator provided APN settings but still can not get generate or receive an SMS
Also, I’m not convinced its an APN issue, I’ve noticed the web interface is very slow and I can see the indication LED’s cycling from 2G, 3G, 4G and up / down the signal strength and then seems to restart the registration cycle
Firmware is RUT2XX_R_00.01.13.3_WEBUI,
