How to cut your micro SIM card to turn it into nano SIM?

SIM card standards are evolving at the same time as the design of our smartphones, becoming thinner. If you have recently changed phones or plan to do so, here’s how to cut your SIM card so that it is finally in the correct format.

Have you changed your phone and you realize that your old SIM card is no longer in the new model? Whether you have a miniSIM card (the biggest) and you want to switch to a microSIM or nanoSIM, do not panic, you can do it yourself!

Why cut out the SIM card will you say? It’s just a question of answering some impatience. Some users want to immediately use their new smartphone. If, for example, you have received a gift for Christmas but you do not have the corresponding SIM card, this may save you from waiting for the operator to send a new card. This also saves you queues in the shop. Only your dexterity will make the difference here.
