 IF  ..  there is even a slight chance of different hardware to be offered in later versions of the Pine phone.

  A slightly more "North American optimized"  modem would be nice !

  Also,   Any  "Possibility"  of being able to use the GPS independent of the Cell modem...  ( ? )

            Thank You  !

Even if it cost extra for the option,  It would be worth it..!

There is no plan to support another PinePhone SKU, this means no plan using independent GPS module.

AWW  !

  Thank you very much for your reply,  even if it is disappointing .

Two things make a modem 5G capable - the frequency bands and the way the modem accesses them. AT&T is using 850Mhz to start for theirs and standard LTE as the method (they call it 5G E) T-Mobile is using 600Mhz, augmented by 700 MHz, and 2500 MHz if their merger with Sprint happens also starting with LTE-A. The Quectel modems are capable of the base 5G standard (LTE).  So, although not really any faster, technically it can be called 5G. I need to read the spec sheets more to see if their modem is capable of the follow on 5GNR standard and I'll probably have to discuss it with their engineers. Or you can. I'll gladly relay who I've been talking to at Quectel if it will help get the ball rolling on maybe using their EC25-AF or another North American optimized modem in a run of PinePhones.

Here's some technical data on the 5G standards

https://www.t-mobile.com/news/americas-f...5g-network


https://en.m.wikipedia.org/wiki/List_of_5G_NR_networks

https://en.m.wikipedia.org/wiki/5G_NR

https://en.m.wikipedia.org/wiki/5G

The first article from T-mobile says they will let anyone with a 5G capable modern on their Network - which is band 71. So I don't know anything about it being closed or having to register your device specially with them to gain access. But then I haven't talked to T-mobile about it. You obviously have so you must know more about that then me.

Or maybe see if their RG500Q is pin compatible https://www.quectel.com/product/rg500q.htm   Or one of the higher bandwidth LTE-A modems, if what I'm reading here is coorect - that at&t and T-Mobile don't intend to use anything other than standard LTE or LTE-A on their 600 and 700 MHz spectrum for now. But if they require device whitelisting ... That would be wasted money if they won't whitelist Pinephone

The RG500Q is a different kind of animal and I have the draft spec. Regarding the AT&T "5G ready" is a marketing term, may not afford to create a PinePhone SKU for this purpose which involve a lot of financial burden (inventory costs).

New guy; sorry if I don't understand everything. I guess I would be wondering, in general, if I were to get one of these phones would I at least get the same ability I have with my 4G AT&T SIM card that I use with my Moto phone now? In other words can it connect like other 4G AT&T phones can do now? Sounds like the answer might be "not quite"? Thanks.

You will get all the US at&t and t-mobile bands that were available at the start of 2019. Yes 4g. What you will not get are the longer range t-mobile  bands that are not in this chip (band 66 and 71). Also there is an issue with 2g, 3g bands that are being dropped in a couple of years and refarmed for 4g/5g. This may affect the functionality of the phone depending on how that plays out. I may have missed it, but I didn't see Pine's answer about whether they have registered their their phones with US carriers which would  enable VoLTE and solve the band refarming issue (as would replacing the module with an EC25-AF

So, in short, without having one in hand, on paper you should be good to go for a few years, but after that maybe not so much. I'm still getting one, but i plan on performing surgery on it and seeing if I can swap the module. I'd be much happier if I could get one with a North American aligned module, or none at all! I have a registered module sitting right here waiting that came from another product
