Jmp.chat provides sim activations for xmr but honestly no matter what anything with a cell radio is being logged by its upstream carrier.

If you want a truely private number, use jmp.chat with a separate xmpp server over something like mullvad.

For what its worth, the sim swap protection might be worth it considering how many services force you to use SMS for 2fa, and they seem to ask for less data than usual.

Is it better than your average carrier? Maybe. Is any SMS/phone call coming out of your personal number something you should consider private from the government? Probably not.

Its still going to have to go over the big boy carriers, and its still probably going to be tied to a phone number several institutions will know is yours if its your main number.

If it isn’t, use jmp.chat, alongside a good XMPP provider and VPN, or forego the PSTN all-together.

Do you not clean your own eating and shitting surfaces regularly?
