A very useful accessory if you have multiple devices that work with SIM cards, because of different sizes usually needed. Each of the adapters in this set is provided with a small tape that holds the card in the recess. The film, which is mounted above, can muster just again when the adapter is not benutzt.Ich use it in order to move a SIM card between a surf stick and a tablet can (as I never mobile Internet reception with two devices the same need).
