AT&T 3G to end next Tuesday in the US?

[svalmont]

I’ve read that AT&T’s 3G will end next Tuesday in the US via CNN. Is this true, and if so where are others moving their service?

For the time being I haven’t switched providers and I’m using postmarketos/Phosh on a pinephone on an AT&T MVNO. Can boot into SFOS as well*, but voice service only sorta works properly – not a 4G-specific thing, just the community port still a WIP (and no camera yet). I just don’t wanna use android, so I hoping that 4G on my now (temporarily?) furloughed Xperia 10 II will work again soon™.

T-Mo says it’s shutting off its legacy UTMS GSM on July 1, 2022. That might be an option for 5 months if you opt for a month-to-month plan.

*Was happy to find out I could do a backup to SD from SFOS on Xperia 10 II and restore on SFOS Pinephone running same SFOS version! Cool!

Soon, with the collaboration of unmaintained, a major update to S1P will be coming out to help with the problem. New features include operation as a daemon (so calls can be received anytime the phone it booted and lipstick is running), registration persistence controls, decoupled UI, better contacts support, early G722.1 codec, L16 codec, network change detection and registration, SIP over tunnel, early SRTP and TLS, TCP mode, early SMS/MMS messaging, UI improvements, independent controls for pl…

You can use SIP and a data-only SIM. Let me know if you’d like any help there.

Thank you, could I use my own number and do calls/texts over SIP? That is my biggest concern.

Yes. First, get a DATA only SIM like one from RedPocket on the GSMA (ATT) network. It’s critical it’s DATA only. Sign up at a SIP provider like voip.ms. If you want, use my referral link https://voip.ms/en/invite/MzMwNzMz. Once voip.ms or your SIP provider is setup, port in your existing phone number. This will cancel you existing service and move your number to the SIP provider. Then swap in your DATA only SIM. Register to the network and setup the APN for internet access. Then install S1P (openrepos) or Grandstream Wave (Android) and configure your SIP provider. Grandstream Wave supports SMS right now S1P will soon. For other options SMS/MMS on voip.ms specifically, you can enable forwarding of SMS/MMS to an email, SMPP server or even to a webhook for posting in Slack.

Let me know if you have questions.

P.S.
If your carrier refuses to release your phone number from your existing plan (due to the cut over from 3G and you being a hold out who is either pending inactive or not in good standing), take the free Android phone they offer and put in your SIM. Your account will register under that phone and then your DID (phone number) will be considered ‘Active and in good standing’ with the network. Then try the port again.

So I have signed up, and downloaded Grandstream Wave. It’s asking for a server to login and I don’t know where to find that?

Using the New York Server listed under DID

Update: Worked with tech support and got it.

I guess there is a native sip app for sfos which probably better suits your needs.
