Changing iPhones
Hi, I have set up my new (second hand) iPhone and want to delete the data from my old phone so that my husband can use it.
I have put my SIM into the new phone and it is working fine but I am unable to erase the data from my old phone so that I can transfer my husband's SIM into this one. Do I need to put my SIM back into the ld phone in order to erase the data? This seems dangerous to me as I do not want to erase my SIM.
iPhone 7, iOS 13
