Hi, recently in my country the 2g network is been shutted down.
I already have a little project to measure temperature and send some alarms over cellular network.
The project use
Sim900 Arduino shield
Arduimo MEGA 2560
DHT22
i im looking an alternative for Sim900 Arduino Shield , because this module only works with 2g
and need to operate with the same Arduino Mega beacuse i dont want to change the microcontroller.
I need an advise what shield i could use, be cause i ddnt find anthing in the market to replace it.
Thank you!
