Do I put old sim in new phone?

[Honour]

I have transferred all my data across from iPhone 7 to iphone 11. Do I still need to put my old sim in the new phone so everything will work? It seems to be working ok except in settings-phone I cannot open this or change caller ID voicemail etc.

Hi @Honour 

Yes you can use the same sim.

Everything else should update eventually.
