Currently, many mobile phones require different SIM card standards. If a standard SIM card should be used in a smartphone supporting micro SIM, customers can convert it at home with scissors or cutters. But if the micro must be inserted into the mini-SIM device, an adapter is required. Users can also make them at home.
Regardless of whether you make a microsim adapter at home or buy it, a preliminary familiarization with the specifics of use and types of adapters will allow you to use the same SIM card for all types of phones.
Types of Micro SIM Adapters
Currently, two types of micro-SIM adapters are available in almost any mobile accessories store. The first type of adapter is a simple plastic design in the form of a standard SIM card with a micro-SIM-shaped hole. This type of adapter is usually available with an adhesive label or thin fixation in the corners to keep the SIM card in place. The second type of adapter is equipped with a cover. It has a thin plastic coating on one side of the space where the micro-SIM should be installed. This cover has a small round hole in the center.
How to make a micro SIM card from a standard
The metal contacts of a standard SIM card, also called a mini-SIM, are the only working parts of the case. Cut off the rest of the sim card to make it micro. Thus, a micro SIM card has a less plastic shell than a traditional one. To make micro without using a template, you must first measure a standard SIM card that is 25 mm high and 15 mm wide. Then measure the distances around the metal contacts or the SIM card. Micro SIM is 12 mm high and 15 mm wide. Mark these measurements on the SIM card and cut them accordingly.
The micro SIM card template provides accurate measurements. To use it, use double-sided tape to attach it to the SIM card. This is necessary so that the card does not move during cutting. After the template is fixed in place, you must cut a "SIM" along it with sharp scissors.
The cutter can also be used to make a micro SIM card. It works like a hole punch. To apply it, place the standard SIM card in the tray, make a sharp press and pull out the smaller SIM card.

It also will not be very difficult. Buyers can make a micro SIM adapter with a cutter. To do this, put the standard SIM card in the tray and pull out the micro SIM card. Then use the rest of the standard SIM card as an adapter. The micro card obtained during this process fits perfectly into this adapter.
The second way to create an adapter for micro SIM is to use an old credit or other similar card. First, measure the size of a regular “SIM card” on an old or invalid bank card and cut it out. Then place it in the cutter tray and cut out a portion of the exact size of the micro SIM card. The remainder will act as a micro SIM adapter.
How to use a micro SIM adapter?
To use the microsim adapter, customers must place a micro SIM card in its hole and make sure that the card is flat on both sides so that it does not damage the smartphone after installing it in it. Then slowly slide the SIM card adapter into the phone slot. If the micro SIM card slides, it may get stuck in the slot and damage the metal contacts in the device. Therefore, be careful when installing or removing the adapter from its slot.
