Multiple problems with upgrade and new phone

[L00py]

Hi, I recently upgraded from an XR to and iPhone 12.

I followed the set up instructions, added the 5g sim, signed into my apple account and it's not working. I have the following problems: -

1] Shows that I am connected to my internet under settings>wifi but the wifi signal icon doesn't activate on the top of the and it's not actually connecting to the internet as I cannot use anything

2] 5G sim isn't working, I called up 24 hours ago to get it activated and still not working

3] Finally, whilst I've signed into my apple ID and it's mirroring my previous set up [the process started as I used my existing SIM], nothing is downloading.

If someone could please advise.

Thanks

Louise

Yu wil need to do a sim swap from your old sim

Just follow the process here @L00py

or

Just use your old sim card unless you are in a 5G area
