Solved: New sim not working

Callumjake95 · ‎10-01-2022

My new phone and sim arrived today and the sim has no signal when in my phone but my old sim works fine. The new sim is 5G so I need to use that one do I need to activate the new sim first or something? I took out a device on upgrade plan

@Callumjake95

To activate the new sim you need to do a sim swap, starting from your old sim.
