Need to erase & reset iPhone 5 & 6s but have no phone service, no network connection no Wi-Fi
I need to reset an iPhone 5 & 6s. I transferred phones and plans ages ago. I have no phone plan, service or am able to get a network connection or wi-fi because of that. How do I reset and erase all content when this is the case. I have tried several things people advised on another post, but none of it works.
Need to Factory Reset & Erase All Content with no phone network or ability to connect to Wi-Fi. Please help
