Without having my notes in front of me, from recollection, the problem is three-fold:
- First, the modem must support wcdma
- Second, the telephony software on the phone must be able to work with wcdma. I know Ofono does not. I'd have to look again at nmcli to be sure., but I don't think so.
- Third, the network must support wcdma. In the US at least, most carriers have, or are retiring their cdma and gsm telephony networks and refarming the bands that held them to 4g VoLTE and the rest to 5gNR.
This is a big change from the traditional carrier switched telephony network to a purely data driven packet switched network. Being the future, each party really has no interest in supporting a dying network technology. So we remain with broken cdma support for Pinephone and all other linux based phones.
