As many other reviewers have pointed out, there is nothing in the adapter to hold the SIM card in place so they fell out freely. The SIM card tray is too small, which protrudes the SIM card and makes it difficult to insert into the device. The instructions that came with the card are very clear and tell you that you may need to staple and/or tape the SIM card. I bought this so I wouldn't have to "tweak" the solution. I recommend anyone looking for a good permanent adapter to look elsewhere.
