Does the SIM800L works in the US? I want to know if the SIM800L works on US soil? I can´t get it to work on the H2O network! Does it work wit ATT or I only need the APN settings? If so what are the commands for data connection and configuration? Does the SIM800C works then?
I wanted to post an update in April 2021 on the status of this question.
The SIM800L will work in the US, but T-Mobile is the only carrier that it can interface with. AT&amp;T shut down its compatible towers in 2017. T-mobile will shut down its 2G network at the end of 2022.
So, the SIM800L is only good for another year and a half. Maybe you're better off finding a different module!
