Thank you for the link.
Honestly the information has confused the matter further.
If they are developing the phone using mPCIe they should continue to use that for the phone. There are a lot more mPCIe cards than M.2 available.
The information from Purism says the M.2 card using the PLS8 will have the uSim slot onboard.
I can’t find a single M.2 card that uses the Gemalto PLS8 modems.
Are they having custom M.2 cards made? If so why not have a global band option as well?
