I finally moved to no-sim setup.
I moved my both work and personal numbers to jmp.chat and got a data only sim from them. Working perfectly fine for my use case.
Its not for someone who make lots of calls and use data, but im mostly on wifi and most of my contacts use either signal or whatsapp.
I cant move out of WhatsApp bcz if i does so many of my contacts will start making normal calls so im keeping WhatsApp and enabled Passkeys in WhatsApp so i dont have to depend on the sms verification with the new voip number.
