Recently installed new VM SIM card into existing iPhone SE (Mk1). All contacts listed/displayed as normal on phone but not displayed when receiving calls!!!! How can I copy my phone contacts to my new SIM card?
Depends on the phone, but there's usually something in the contacts setting to say whether the phone, SIM or both should be active. There may be an option in each contact to make the copy, or sometimes there's a "copy all".
Only speaking for older phones here though, smartphones may assume you're using some cloud service.
