Possible I'm missing it, put seems like if you are going to build a phone the first step would be to state what governements and networks would support it.
For example, appears that in the US that even if the phone would have worked with AT&T in the past, that as the end of 2016, that is no longer the case:

- tiatia 10y agoMaybe some people would give a f. and just connect it to the network, certified or not?

See https://www.sfmta.com/about-sfmta/blog/why-muni-arrival-times-are-off-week-and-how-we’re-working-fix-them https://www.sfmta.com/about-sfmta/blog/why-muni-arrival-time...

As Muni was the first transit agency to adopt the system, the NextMuni infrastructure installed in 2002 only had the capacity to use a 2G wireless network – a now outdated technology which AT&T is deactivating nationwide."

Seems to agree with you. They recommend using the simcom 5320 versus the 2g only simcom 800 used in this project.
- joecool1029 10y agoGood thing T-Mobile made a commitment to keep their 1900mhz GSM working through at least 2020. (UMTS might actually sunset first) Source: https://newsroom.t-mobile.com/news-and-blogs/att-2g-iot-lifeline.htm https://newsroom.t-mobile.com/news-and-blogs/att-2g-iot-life...
- Nexxxeh 10y agoThe project lead is in Latvia. Is anyone in Europe sunsetting 2g? Any network that does 2g GSM will work, and if it's pin and AT command set compatible with the SIM800 then any other GSM module will work. If not, it's a straightforward setup to adapt.
