How to make a micro-sim card?

Today, most manufacturers of modern tablets, as well as smartphones that support 3G, aspiring to miniaturization, are trying to use micro-sim cards more often. And of course, the pioneer of this whole process is rightly considered to be Apple with its iPhone 4. Their initiative was very much liked by manufacturers of mobile phones from Korea, and Samsung soon also switched to a new format. Micro-sim cards from ordinary anything (except size, of course) do not differ. And only the superfluous parts of plastic are cut off in the last, while the entire technical stuffing of the device remains untouched. The standard map has a size of 15x25 millimeters, and its micro sample is 12X15 millimeters. Excess plastic is painlessly removed, and you get a sample of the size you need. But how to make micro-sim cards from ordinary ones?

You just need to contact the operator

Yes Yes. Do not reinvent the wheel. Do not puzzle over what and how to cut. Almost all cellular operators support this technology, and you can simply refer to them and ask to replace one card with another. The most important thing is that after such an exchange the former number and tariff will remain fixed for you. However, not every owner of such a device will go to the cellular communication departments to request micro-sim cards. Or maybe it's just in our curious nature. All I want to try and do myself. Especially since a micro-sim card, the price of which is not important (it is given to you free of charge when connected to a particular operator), in case of spoiling, it will not cause particular distress. In order to get a large card from the micro, it is necessary to have a special device that cuts the excess strictly in a certain contour. But this is all only when your task is to put the business of creating small sim cards on the flow. If there is no such task, then you can cut yourself off by using the most elementary devices.

Only paper and scissors

You need a micro-sim template on paper in a one-to-one scale. Then follow the instructions below clearly. If you make a mistake, you will have to be puzzled by the question of where to get the micro-sim card, since the device with the chips will be spoiled. A qualitative result will be greatly facilitated by sharp scissors. It is also important to trim the card, as they say, with a margin, in order to then be able to fit it to the desired size.

Sequencing

1. Fix on the template your Simka (precisely the side on which there are no contacts) with the help of glue. Note that the position of the contacts on different cards is different, so be guided, first of all, to the platform of microcircuits, and not to the edges of the device.
2. Using a ruler and a sharp knife or a sharp pencil, accurately and accurately map the cut line.
3. Cut the excess plastic with scissors. Remember that under no circumstances should the line on which the cutting object has walked passed, should not protrude on the metal surface of the microcircuits.
4. In the end, you can easily deburr sandpaper on the edges with sandpaper . That's all. Now you can fully use your micro-sim card.
