For a couple of years, I have had this old iPad around the house that won’t let me turn on the WiFi. Because of that, I couldn’t reset it and erase the contents. I couldn’t even log out of my iCloud account.
After laying around in a drawer for a couple of years, I finally took my phone’s SIM card, puit into the iPad, and erased it. Fortunately, I had spent the extra money on the SIM model. (With the iPad asking me if I’d like to let the updates finish before I erased it).
But, what would have happened if I had a WiFi only model. How do you erase an iPad or iPhone if you can’t connect it to the iCloud network or turn off Find My?
