Findmy switched off by mistake
Findmy switched off in error, using old iphone. I wanted to give my wife my old iphone, but I didn't understand the proper procedure. I put her simm in my oldphone then switched off Findmy, not realising that this would apply to my new iphone 15 pro max. I have now removed her sim from my old iphone 6 and put it back in her iphone6 which has a broken screen. How can I get Findmy to work with my current iphone 15 pro max?
