I have 2nd hand pixel 8a with grapheneos and i havent putted sim card in it since i have it, in my country i have to have registered sim card, iam afraid of IMEI be linked with sim card and once i put it in im f**ked, the reason i need to put card is to verify bank which need sim card being in device.
I did some research but became dumb from too much information
(sorry for my english :D)
Edit: also i want to be private because of my feature, idk if i wont live in country where propaganda is normal
Kycnot.me is your friend. Go to a public WiFi (ideally use a VPN), get some Monero, buy a phone plan without KYC.
