Sim card stopped working

[Nannah]

I just upgraded from the galaxy s20 to the s24 ultra, I put my sky sim in the s24ultra and it was working fine for a few days, but since yesterday it's says emergency calls only, won't go online unless I'm connected to WiFi and it won't connect to the sky network, I've tried getting network settings sent but nothing comes through, I also checked the sim in my old phone again and it won't work with that either, I'm not too techy so I'm not really sure on what's happened with it, any ideas?

I forgot to mention I've also factory reset the s24 ultra and it's not changed

If nothing shows then it might be wirth contacing Sky si they can send you a replacement sim incase the one you have has devloped a fault. You will have to contact Sky, perhaps via social media as there are links t the bottom to their sites.
