Adapters for SIM cards: convert a micro-SIM card to a standard

The familiar SIM card is changing - more and more devices are starting to require micro SIM instead of the usual mini size, which has been used for many years. Cropping a mini-size card to a micro size is not too difficult, but adapters are required to return to the previous setting.

In addition, if you do not take care and try to trim yourself (and then insert the cropped card into its original shape), you risk damaging the thin connectors of your phone.

The history of "sims"

The subscriber identity module (SIM) card is used in mobile phones as a memory chip that contains data required for authentication in the mobile network. The early cards had only a storage from 16 KB to 64 KB, which was enough to copy authentication data, mobile data settings, and also some contacts and text messages. More advanced features were introduced with the advent of multimedia messages. Today, some SIM chips with the same connection format can have built-in microprocessors for additional functionality. Modern developers are working on adding even Near Field Communication (NFC) to the SIM card chip.

Segment and map size

The original format of the SIM card was exactly the same size as that of bank cards. Very early mobile phones actually used these relatively large "sims". What we call today SIM-cards, in fact, is in mini format. When you buy a new SIM card, it may be placed inside the plastic form of the old sample and subject to expulsion from it. Presumably, this is done either to simplify production, or to maintain backward compatibility. Nowadays it is increasingly possible to find out that operators implement micro-SIM in a similar mini format.

Cropping the SIM card in other formats

Cropping the map to the desired size is not a big problem. There is a special cutter for "simok", which allows you to do this most accurately. Many more difficulties begin when you need to use the micro on the mini device. To do this, there are various adapters for SIM cards on the market.

Cross-compatibility

Most modern smartphones have a tightly installed SIM card slot, not a swivel holder. Some models go even further (for example, Nokia N8) - they have a push-to-eject system. For this reason, such gadgets have a very limited space, in which the card should stand.

Because of this poor-quality adapters can easily get stuck on pin pins and cause damage when trying to remove them. For this reason, it is not recommended to make an adapter for the SIM card yourself.

What adapters are available?

Today, two types of these adapters are available. The first one is called Outline, and it is just a piece of plastic in the form of a mini-SIM with a hole for the micro-SIM. They are usually supplied with an adhesive label to hold the SIM card in place.

Adapters for SIM cards of the second type are called Backed. They differ from Outline by the presence of a thin plastic wall on one side of the space with a round hole in the center.

The best adapters for SIM cards

As noted above, the main problem is that phones tend to support different card sizes, and sometimes a SIM card can not be replaced by a mobile network operator. It is for this that a special adapter for the SIM card is needed. These adapters are quite cheap, but you need to consider some of their features, so that your "simka" is ideally suited to the phone. Where to buy a SIM card adapter? As a rule, the widest choice is presented in various online stores. Below is the rating of the most popular devices.
