the product is good. just useless.
The product it self is fine. it it the same sim connector as the one in the samsung galaxy s2. but the problem is that you can't replace the old sim connector and is you dont have a very smal soddering iron and some propere skills in using them there is no way for you to atach this sim connector to the main board of the phone.
don't buy this product. You can't use it.
