I live in the UK, and I've read some articles just now that this module never worked after 2017 in the USA because it needs "a two frequency network"?, and support for 2G(phased out in America?).
It sounds like there's America/Europe/Asian standards for the networks?
So if that's the case in America, chances are there's regional "frequency settings" or 2G support missing for connection to the EE network in the UK too?
Is there any modules like this one that CAN be used in England with a brand new EE SIM card?
I've connected it to a 5v 5A lab supply, and used an Arduino Nano, and talked to it with AT commands.
It reports 3 networks - T-Mobile, O2, and Vodaphone. But does not connect to the T-Mobile one (EE SIM card). Even when I send the command to connect explicitly.
The SIM is an EE PAYG, activated on another phone with £10 credit.
I THINK it's because the 2G required isn't available around here in the UK? Or the frequency used is for Asian networks?
So - if the SIM800L is a bust - can anyone recommend an alternative that would work with a modern SIM card, in the UK?
