T-A7670E/G/SA R2

Go for the A7600 instead

This version of the board is not stable.
The examples provided on GitHub do not work without customization and some libraries require manual update without compatibility other boards versions which is tricky if you use different boards.
I also encounter unstable RTC_DATA_ATTR that cannot be used reliably to count number of boots (therefore no possibility to manage variables during deep sleep mode)

Great way to learn GSM

Was a very easy way to go from WIFI to GSM. The examples give you a great foundation to build upon.

Excellent smart modem device

The Lilygo T-SIM A7670E is a great device, very adaptable and with a range of features and capabilities. The documentation could be better, but I worked everything out in the end.
