@paoloredaelli @lupyuen I was under the impression that all US carriers shutdown 2g services but I noticed a few days ago my phone had an EDGE connection, which I believe is 2g. I use a T-Mobile MVNO. We previously used AT&T MVNO's but our 4G devices stopped working and we constantly got messages nagging us to purchase new devices, so we switched to using T-Mobiles network.

Paxo Phone (#ESP32) is a wonderful achievement for a 16 years old dude. Yet according to comments on https://hackaday.com/2023/08/03/open-source-cell-phone-based-on-esp32 it's modem is "only" 2G which is being phased out in many countries. Ditto for 3G (in Australia)
