How to cut a SIM card into MicroSIM

Phones evolve more and more, changing in size as the years go by. The trend today is to make everything bigger. With screens, cameras, linings, among other things constantly increasing in size, it is curious that the SIMs are reduced. For this reason today you will learn how to cut a SIM card in MicroSIM or nano.

And it is truly curious that the only thing that does not increase but decreases are the SIM cards. But, regardless of the reason, this is happening all over the world, with users being forced to change lines, because their SIM card is not compatible with the new mobile they bought, for this problem today you will see the simplest solution.

Although as advice you should look for what are virtual sim cards and how do they work? , because maybe you don’t have to cut yours.

SIM card types

Now, before being able to cut a SIM card in MicroSIM or nano, it is necessary to first know what you are talking about. Today there are four types of SIM some current and others obsolete these are:


Its size is 85.6 x 53.98 millimeters, they were similar to credit cards and used in older phones, they were withdrawn from the market years ago. MiniSIM: These are the first to be implemented in lighter and more compact mobile phones, it is the typical one that is placed under the battery in a slot, it measures 25x 15 millimeters.


Some of the smallest that exist today, were invented by Apple and are the standard that is used today (this is because mobile phones increasingly come with more internal components so you have to save space), measures 15 x 12 millimeters.

NanoSIM : These are the smallest of all and its use occurs more than anything in higher-end phones (it is practically only the chip), its size is 12.3 x 8.8 millimeters. Now, having finished with the review on each type of SIM, it is time to cut a SIM card in MicroSIM or nano and for this you do not need to use any luxurious device, you simply need:

A PDF template with the marks of the different sizes , a scissors (which will make the cut), a ruler, a pen (to make the marks) and sandpaper (to smooth the final edges).

Cut a SIM card into MicroSIM or nano

The moment of truth has come, cut out the card. Once you have the above materials, you have to get going. It should be noted that today’s operators offer you the different sizes at once without having to ask for it, but for those who have a super old SIM that do not want to change this method is necessary.

The first thing is to take the PDF sheet that you should have printed with the model you are going to follow (you can get it on the internet) and put it on a flat surface, then place the card on the sheet so that it matches perfectly. Then use the ruler as a support to mark the lines where the different cuts will pass, it is advisable to use a marker or fine pencil.

Once this is done, pass the scissors through the previously marked lines with the greatest possible delicacy , so as not to touch the chip that is the important part. Then smooth the remaining edges with the sandpaper (so they do not bother when putting it on the phone).

Then you just need to put the SIM card in the corresponding place of the new mobile and that’s it. This method works to return your Micro or Nano card and is obviously permanent so you must be very careful.

If everything went as planned then your phone should be working with the new SIM , so you can say that you learned how to cut a SIM card in MicroSIM or nano .

Remember that this card is like the brain of your mobile, so you would not be looking for more information such as how can the sim card be blocked? , or how to activate an inactive chip or sim card , and so you can handle the issue perfectly and never go offline.
