Hi there I’ve just received my new iPhone 13 promax and a new Sim card I’ve posted and set the phone up but for some reason I’ve not got any bars and can’t make any calls?

You can use your old sim or do a sim swap to activate the new one if you're in a 5g area Guide: Sim Swap: a mini guide 2017 update
