Old Teslas (like 5+ years) will lose net when 3g goes. You can do a computer upgrade but I don’t think it’s cheap ($500-$1500 range offhand)
It’s really annoying this isn’t software defined for future proofing. As long as your RF hardware is robust onboard, the rest can be done in software.
VoLTE is so damn frustrating. LTE works via plug and play with any phone that supports the correct bands, but VoLTE doesn't. I have a Sony Xperia phone here in Canada and it's just not possible to use it on VoLTE without rooting to install specific provisioning files and whatnot. And that's not even counting how you can't just go from country to country without changing firmware. I've always used a local SIM whenever…
EDIT: Apparently it does automatically but they disable the toggle to turn it off.
Got the letter that ATT is shutting down their 3G network and that my phone will need to be upgraded and they will send a free replacement that will automatically be activated in 30 days if I don't activate it myself (thus rendering my current phone unusable on the cellular network).
My current phone is compatible with the ATT LTE network and I don't want whatever crappy free phone they send. So I called, waited over 20 minutes on hold, and right as I'm verifying the account information to the representative the call ends and they don't call me back.

the radio cannot be software defined (and user modifiable) for type acceptance and regulatory reasons
The author appear to be using OnePlus 3T which uses a Qualcomm Snapdragon 821 with X12 LTE Modem. It support VoLTE with AMR-WB but not EVS. I doubt EVS is a hard requirement until VoNR in 5G. But not supporting it seems strange. In the old days Network require certification for phones to work. I am not sure if that is the case in US but for many part of the world that is no longer required. It could also be the lack…
> Turns out AT&T operate on a whitelist system [1] ( What ? ) with a list [2] of phones. Sort of surprised but also not so surprised coming from an US Mobile Carrier. Pretty sure all carriers in Poland operate on a white list of phones. https://wificalling-volte.pl/

Are you suggesting some 3G RF hardware can be retrofitted with software patches to be compatible with 4G networks ?
This is theoretically possible (SDR) but it's very expensive. (Before anyone replies about $20 SDRs, those aren't even close to 4G/5G capable.)
I think the answer here is an internal USB modem or something. Easy to upgrade. Just up to the car manufacturer to commit to writing new drivers. (I assume that they don't want to do this, so are probably happy when technology changes out from under them. Everyone has to buy a new car!)
BMW recently sent out an email of impending loss of 3G connectivity. > The decision to phase out 3G network technology was made at the discretion of the respective cellular carriers and lies beyond the control of BMW. As a result of the sunset of 3G service by wireless carrier partners, by February 2022 your vehicle will no longer be able to receive any ConnectedDrive/BMW Assist services, such as BMW Assist eCall, Ad…

Indeeed. Last time I looked these chips were $1300 each in quantities of 1000. Too expensive for even a luxury car. I think the answer here is an internal USB modem or something. Easy to upgrade.

Nuking the Messages app also had a nice little benefit: No more text spam that the carriers refuse to do anything about.
