@air409 In the North American market yes. Verizon has already black listed it, so you can't put it on their networks period. AT&T will turn off 2g3g voice Jan 2022. It has not made clear if it will blacklist the device. If it does, you won't get service with them either. Not even data. More likely, they will continue to allow it as a data only device.
T-mobile will turn off 2g3g voice Jan 2021. They, currently, do not use whitelists and plan to continue allowing non-VoLTE devices on as data only devices.
As such, you will need to use Linphone, or if Anbox is fixed, any Voip app, talkatone, truphone, etc., to make phone calls. It really isn't any different than using Google voice, etc. In fact, call quality will be higher.
