Where is here?

You can always get a esim and pay with crypto or a prepaid credit card. Airalo etc

But even getting the sim is only the start of the battle. Being on the cellular network builds up a time and location profile of the phone which can highly correlate to an identity / house / activities.

Not to mention once the phone is logged into the network it’s phone IDs won’t change even if you change the sim card / esim.
