I’m trying to erase my old iPhone but getting verification failed message. There was an error connecting to the Apple ID server. Is that because the Sim card has been transferred to the new phone?
Do you have to have the SIM card installed to erase an old iPhone? I already set up the replacement iPhone. When I go to the old iPhone to erase all settings/erase iPhone, I get an error message that says verification failed, unable to contact Apple server
iPhone 6, iOS 12
