The problem with IPhone 4 not able to detect the T-mobile’s Sim card when unlock is because T-mobile Sim card is a lot thicker than the IPhone 4 original Sim card. Just sand down the plastic side of T-mobile Sim card’s thickness to match the IPhone 4 original Sim card thickness.

I can not believe it but it worked for me too and I tried everything first. I dropped it on both ends. at first from 1′, then from 2′ and finally from 3′ on a carpeted surface and it worked instantly. Wow, Steve Jobs really was a genius.

THIS WORKED FOR ME : It seemed that the card was "floating" a bit in the slot. In order to tighten the card against thr contacts I cut a standard sheet of copy paper. Cut it to size of the mini card and glued it onto the card with glue stick. This was enough to make it work and be recognized. (You might want to write your sim card # on a sheet of paper to keep BEFORE you cover it up)

I had a iPhone 4 for over a year and it suddenly developed this "no sim installed" problem in the middle of a phone call. I tried all the helpful tips from online forums none of which helped. In the end I contacted my carrier / service provider and after a procedure of trying various things including taking out sim put into another phone they agreed to supply a new sim card. Since fitting the new sim card all is working perfectly I now have a better signal than ever and no drop in service and definitely no sim card problem messages.

My sim stops working every time I drop my iphone. I have tried many of the above solutions and have managed to get it working after hours. I hadn’t tried dropping it again though. Surprisingly, it worked instantly. Thanks a lot.
