MY IPHONE 4 WONT WORK WITH MY SIM IT WORKED BEFORE
MY IPHONE WORKED WITH TMOBILE THEN I FACTORY RESET AND IT WOT RECOGNIZE IT
INVALID SIM PLEASE INSERT A SIM WITH NO PIN LOCK TO ACTIVATE I PHONE
Was one of the above what you where asking well in my weird it experimenting ive found a simple solution hope it works for you.
1. You reset your iphone to factory settings ad now it wont recognize your sim to let you activate it heres how youll have to reactivate it , if you dont want to v isit the tmobile shop. .
Yo will need -
Pc - itunes on there
Usb - that connects iphone to pc
2- Now ive you had a sim in the phone before that worked but now doesntthen this is what you should do -
in most cases it will be t mobile in the uk or usa at&t i found it happens alot in those phones .
Now as a freind or someone you know will probably on a contract phone and simply insert there tmobile sim into your iphone hard reset by pressing the power and home button until it turns off .
When it comes on insert the usb into the iphone and pc it will automatically connect and activate the phone .
The simple thing is you borrow a sim from someone for the two three minutes it takes to sync the phone with itunes .
3.Now reinsert your sim that it wouldnt recognise before and connect it to usb and let it sync again
This definately works with t mbile and at&t for usa . just borrow a sim thats on a contract and activate with that then reinsert your old sim and it will work again voila .
