So I've just moved onto the GrapheneOS, I wanted to set up a my sudo number, but if you want a Uk based number they want photo ID etc because of ofcom etc, I did set up a US number but if I use it to phone friend's it just flags as possible spam, so I am considering using a SIM as a last resort in case of emergencies for my family etc, the question is, do I use my old sim, or is it best to get a new sim, with no reference to my personal details address etc, and just leave it in airplane mode unless I really need to call family, I use signal to communicate normally, but if I have no access to data then I can't use it..... Or would you go down the Data only sim,?
Thanks
