3G/4G modems - Alternatives?

@kieran

Until someone from Purism wants to provide actual information it’s all just speculation.

I think they repeated the info sufficiently often. No slot on it, not custom made.

5G Mobile Cell Phones in the market in 2019-2020

Well, we need to work with what we can find on the market right now, which is 3G and 4G modems. The good news is that modem in the Librem 5 will sit on a M.2 card, i.e. it can be replaced! Cheers nicole

Another delay in the delivery of the Librem 5

Except that it does not come on a M.2 card, maybe. The devil is in the details. Data will most likely work but voice can be an issue because of all the different digital audio interfaces and firmware support by the modem. We are currently also evaluating another modem with more supported regions. Cheers nicole

Basically says, if the m.2 module you find is supported on Linux, has the desired bands and codecs n stuff, it’ll work.
So summary:

• nobody sells m.2 modems with SIM slot
• Purism has that slot on the mainboard
• every standard module is a possible candidate
