Hi David,

To be honest, I’ve never seen that board before, so I can’t give you any feedback. I also never used GSM with the ESP32 and I don’t have any examples with it.

For what I can tell, that seems like a good board that should do what it claims to do, but I would try to search for reviews or project samples to see it can do what you want.

Thanks for asking!

Thanks for your rapid reply. Do you have any non ESP32 project examples (eg Arduino) using GSM connectivity?

Yes, I have three tutorials for Arduino using the SIM 900 board:

• Guide to SIM900 GSM GPRS Shield with Arduino
• Request Sensor Data via SMS using Arduino and SIM900 GSM Shield
• Control a 12V Lamp via SMS with Arduino

I hope that helps,
Rui
