Get two simcards, verify one and keep the other anonymous and unverified. Always use the unverified one, in a cash-bought unregistered phone, to contact escorts. You don't need porn-clearance for that.
To those who still haven't figured out why this is important: there are nutters out there, and some will lie to the police to get them involved. Maybe even get themselves pregnant and get the CSA involved (you took your used condom home with you?).
The risk is small, but the consequences could be horrible. Just a little bit of extra care could save a huge amount of grief.
