New phone help with sim

[Nikkinido]

Hi everyone. I got my new phone yesterday and put my old SIM card into it, but it isn’t working. The phone isn’t detecting the SIM, so I have no signal or service. Has anyone else had this issue or know how to fix it? Any advice would be appreciated. Thanks!

Does your existing SIM still work in your old phone?

If your new phone is a dual-SIM slot, does either slot work?

@bristolian  iPhones do not have a dual sim slot, or at least never did unless the latest one does, but doubt it, there is only one slot.
