Size comparison of SIM card formats

SIM card sizes can be confusing at times, especially when juxtaposing mini, micro and nano or your own Adjust the SIM card from one size to the other want. In this article I would therefore like to give you a small overview of the currently common SIM card sizes. So you know immediately whether you are using a Mini SIM, Micro SIM or Nano SIM or need it for the new smartphone / mobile phone. I would also like to list which SIM card size is used in which iPhone and iPad - and what an Apple SIM is.

SIM cards: size comparison of the four SIM card formats

The Use of the SIM card as access to the network Telecommunication and (mobile) data transmission comes from the phone cards, which were / are used in credit card size for example in telephone booths. This still exists today Full-size SIM cards for telephone booths. The size of the cards is 85,6 x 53,98 millimeters. It is the (local) standard size for a full-size SIM card. The little part that you break out to put in your cell phone or smartphone is that Mini SIM card. From this goes the Micro SIM card and then the Nano SIM card Hervor.

SIM card dimensions: Mini SIM, Micro SIM and Nano SIM

SIM card sizes have been reduced more and more in recent years and decades. One of the reasons for this is that the space in cell phones and smartphones is getting smaller and smaller. More and more technology, new chips, sophisticated sensors, a cooling system, the battery and so on have to find space. SIM cards had to decrease in size and the 7 mm jack socket on the iPhone 7 and iPhone 3,5 Plus had to give way. Here is an overview of the individual SIM card sizes:

SIM card Height Width
Full-size SIM card 85,6 mm 53,98 mm
Mini SIM card 25 mm 15 mm
Micro SIM card 15 mm 12 mm
Nano SIM card 12,3 mm 8,8 mm

(Of course, the height and width considerations depend on how you turn and look at the cards, so the height and width are interchangeable here.)

Cut to size or adapter: Adjust the size of the SIM card

If you want to change the size of your SIM card, for example from mini to micro or nano or from a small format to a larger one, there are various options. For example, there are stencils on the Internet that can help you with cutting. You can also go to Amazon SIM punching to buy. For reasons of guarantee, however, I would advise you to have the SIM card reduced in size by your specialist dealer / provider. SIM card adapters are available to enlarge the format, so as to downgrade. You can find one on List of the best SIM card adapters.

    the problem starts when you cut or have to cut a smaller "MINI SIM" from a FULL SIZE SIM card (SIMYO2005) in order to continue to use or be able to use it.
    If this reduced card, on which the SIM card number is no longer completely available, has to be returned to the provider (previously SIMYO now BLUE) after deactivation with credit for reimbursement of the remaining credit.
    washat you then. really nothing
    SIMYO had the bad habit that one always had to reload amounts in order to extend the activity. So when not in use (because of unfavorable tariffs) credits accumulated, which is then doubtful to ever get back. BLUE is now finding it very difficult to provide crystal-clear written assurances. A rogue who thinks badly.

      Thanks for the hint. This procedure is new to me. But I've only had a prepaid card once in my life. Actually, they should be able to read out the SIM card number electronically ... but ok. Of course, if there is a way to make money, then this is the best way to go. ;-)

    that can be so, but the "evidence" is gone and in the hands that should pay off.
    Exactly the same situation as:
    1. In medical law, where the medical documentation is located at doctors and hospitals, which should be criticized in the event of a problem. An absurdity.
    2. Deliver change through the bank to the state central banks cost-effectively / free of charge. A bag with the change will be sent to the customer without proof of the size of the contents.
    There is hardly any other way here, but difficult to accept in times of receipts and receipts.

    The case with the "return" and payment of the remaining balance is not yet closed. let's see

    For me, prepaid is a good thing, a lot of personal control and self-determination.
