Resolved! Do I need to cancel sim-only contract if upgrading to o2 via a different provider?

Hi. My sim-only contract is due to end 18/11/21. I’ve seen an o2 through Mobile Phones Direct - do I need to cancel my contract and settle up before switching or will be it done automatically once I switch? Thanks

Resolved! No 4G or 5G

I’ve had my new iPhone 13 pro max for a week now. It only operates on Wi-fi. When there is no wi-fi, my phone is useless, I have no 4G Or 5G.
