I would like to use Tor/Orfox/Orbot on Android while using a Pay-As-You-Go SIM card. I live in the United Kingdom.
Is this possible?
If so, did you encounter any issues?
Do I need a registered SIM?
It is possible:
It is now on Tor. However, you should know what Tor is. It is a way of keeping you anonymous by hiding your IP address.
This will have 2 effects.
