You have become the proud owner of a new iPhone and only one thing can upset you. It has a slightly different standard for sim cards. They are called microSim. There are several ways to stay with the same number. Do not buy a new tariff with each phone.
MicroSim is not that much different from a regular SIM card. If you look at both maps, you will see that they have the same workspace. The only difference is in the size of the fields around. The easiest way to replace is to cut out a new small card from a regular “big” card. Without additional devices, this can be done using nail scissors, a ruler with millimeter marks and a simple pencil. Regular SIM card is 25mm long and 15mm wide. MicroSim has respectively 15 mm by 12 mm. Draw a 15x12mm rectangle around the chip. Cut off the excess carefully. If it is still larger, trim it. There is a dedicated SIM card cutting tool. You can buy it in the online store. The cutter is easy to use, you just need to order it and wait for delivery. Then everything is simple: stick the card into this device, similar to a stapler, and cut it off. There is a chance that you will not succeed and you will simply ruin the map. Therefore, it is better to contact your operator. Most of them replace old-style cards with new ones without changing the tariff and number. In order to do this, you will have to drive to the nearest sales office. MTS proposes to carry out a replacement in a retail store.
