On another note, I want a phone that complete has no connection to the phone system, ie. no phone number, but has cell connectivity so that I can make data calls using whatsapp or similar. Can someone please make this?
WhatsApp/Signal/Telegram require a SIM enabled non-VoIP phone number available to receive SMS at all times in case they decide to reverify you. Doesn't necessarily have to be the same device, but still quite annoying.
