The 2G GSM modem seems like a non-starter for those in the U.S. since AT&T (and apparently T-Mobile too, at least locally) has disabled such technology on their towers. I'm a bit surprised a 3G modem wasn't made standard, with an option to upgrade to LTE (even if it were to cost a tad more).
- CRImier 9y agoI'm working on a 3G modem board this week, based on SIM5320 (as suggested in a HackerNews comment, IIRC) - the way I'm designing it, it's pin-compatible with 2G modem I have now, so should be a drop-in replacement. Hope to have the PCBs in a month, and I'm also planning to release a timelapse of me drawing this board (with comments) - for educational value.
