iPad 2 Sim not detected - Page 4 - GSM-Forum

This is the fix that worked for me. The jumper was not necessary since there was continuity for each of the pins. Once I created a paper barrier between the metal case and the card reader and did a reboot It came back to life and once again read the card.

Thanks for figuring this out - and thanks for sharing

So I've got about 10 iPad 2's that all have this exact same problem. Ive ran the traces to the points where continuity is not found, still saying no sim card found, tried making a barrier to ensure there is no short, still the same. Cleaned the sim card and even tried 5 other ones, still no sim car found. Factory reset and did the whole airplane mode, still no sim card. Could it possibly be the latest version of IOS thats causing this issue? Any other suggestions? I've even taken a sim card and soldered the traces directly to the card itself and completely canceled out the card reader and it is still a no go.

The problem is I've tried running the traces like I stated in my previous post. I even went as far as to solder the jumpers directly to the SIM card it self to by pass the card reader. Still no luck.
