YES!! It's become the norm to have a 'number'. We cannot own these numbers, only rent them from a limited number of companies (oligopoly) for a high price, whilst simultaneously sacrificing our geolocation, content, and identity.

SMS is not secure 2FA, we all know this. I have graphene, and it does NOT have a sim (nor e-sim).

By switching on airplane mode, you can still use wifi and bluetooth but your IMEI is not continuously transmitted to every base station in the vicinity.

If you need SMS for that annoying provider who doesn't support true 2FA then you can use crypton.sh and rent a number for a few euros a month

If you need internet (and who doesn't) then you can buy a throwaway sim each month and stick it in a VPN dongle. This way ALL your comms are encrypted, double-encrypted if you have VPN on your phone also.

Yes it means carrying a dongle in addition to a (graphene) mobile, but you can finally use a mobile and have true privacy.
