It's not supported and I also reply here.
The 2G has no future and not available in many mobile operators worldwide.
The better solution is to use pocket WiFi Hotspot with 4G/3G sim card if you don't need the voice call, SMS and MMS services.
I dont know if this helps but I faced the same problem, however, I managed to solve it and I have posted my solution as a GitHub Repo
Hi @mobizt, I would really like to thank you for creating such a useful library, I am thinking of interfacing the GSM module (SM 800) with ESP32 as a backup plan if wifi/internet connection is lost. I was checking this article it uses the TinyGSM library to do an HTTP request. can we somehow use TinyGSM to connect to firebase and update values using the GSM module?
