<![CDATA[oneplus one 4g on t-mobile?]]>does the oneplus one support 4g via t-mobile (USA)?
I can't save APN settings via the settings app and the 2g/3g/4g option won't stay selected.

I just don't understand why the OPO with UBPorts isn't keeping the 2g/3g/4g settings because as you said LTE should work on it for data (and is working on a galaxy s5 and the pinephone). The APN preset is correct in the settings app.

The OPO can use LTE for data, but without VOLTE support in UBPorts, voice calls will still be carried on 2G or 3G (when and where these services still exist).

Thank you! I'm not using an Op1 currently, so this is neither my circus nor my monkeys, I was just trying to help... but I'm sure others will appreciate your explanation.

The OPO can use LTE for data, but without VOLTE support in UBPorts, voice calls will still be carried on 2G or 3G (when and where these services still exist).

If you're using the OPO with UBPorts somewhere/sometime that 3G and 4G are coexisting, you can watch it happen: Pull up a web page using mobile data, and you'll see the "L" icon in the status bar on the top. Now, place a voice call and see the "L" replaced with "3G". This is the device falling back to 3G since there's no OS support for VOLTE. End the call and "L" comes back.

T-mobile's announcement of 2G and 3G sunset for their US networks says the T-Mo 3G service ends July 1 2022, and this is the one we care about for the OPO. On that date -- unless you're somewhere T-Mo is still supporting 2G for legacy hardware -- you won't be able to make calls. But depending on where you are, you may get cut off sooner since Big Pink is decommissioning 3G stations as we type and you'll be out of luck . . .

This has already happened to me with an AT&T reseller. 3G service on that network ended Feb 22, but had been degrading before that date. OPO now sits in a drawer unless I need to play Tux Racer. 😞

BTW, UBPorts (and other alternative OSs like Sailfish) will work -- kinda -- for VOLTE-only networks on the Pinephone since that device has VOLTE implemented in hardware in the modem.

If they still support it then they can help you other than that maybe another network can. Unless a US member can answer for you I can see little other option.

Was working on a galaxy s5 in Jan 2022 which had no VoLTE)

"What does the Sprint 3G (CDMA) network retirement mean to me?

On March 31, 2022, Sprint’s older 3G (CDMA) network will be retired. If you are still using a device that is dependent on Sprint’s 3G (CDMA) network or that does not support VoLTE, you’ll need to upgrade to a more modern device no later than the end of 2021 to continue getting service, including the ability to make 911 calls depending on your location"

In any case, 3G is working on the OPO with UBPorts, so I don't see why LTE wouldn't work from the carrier's perspective

VoLTE is not a requirement to use T-mobile's 4g anywhere yet from what I gather.

Are you sure? This makes me wonder: https://www.xda-developers.com/t-mobile-att-require-volte-phone-calls-shut-down-3g/

Or a Community member from the US maybe able to help.

how can I get UBports to work with t-mobile's 4g on the Oneplus One?

If T-Mobile is only offering VoLTE as their version of 4G in your area (country), then you are out of luck because Ubuntu Touch (that's the name of the OS) is currently not supporting VoLTE.

UBports, however, are aware of the problem and it has a high priority. They will most likely start working on it right after the jump to the Ubuntu 20.04 base. You don't need to do anything to get them to work on that. :winking_face:

The hardware itself can connect to T-mobile's 4g bands according to:

It seems they will discontinue 3g service this year, so 4g will be essential for web browsing on this phone
