The SIM card fray all and the card needs a little back and forth can be moved, so that the contacts fit and must be handled with the arrows (deburring). Advantage is in the set of that Sim Card Adapter and the pin to the card carrier from iPhone and Co. out push here are. The service is very good and the seller are very accommodating. This, in turn, I've rarely seen and therefore the assessment is worth 4 stars.
