Hi, I have a pay monthly SIM and I am moving back to Australia for 2 years. I need my UK number for 2FA and to receive any calls. I don't need data. I am trying to understand how to have the SIM connected to AUS networks without triggering daily roaming charges so I can receive the odd text and call from the UK? I have been told in a Three store that roaming charges are only triggered if data is on and it doesn't cost extra to receive texts or calls from the UK. Is that correct?
