SIM Cards: Mini, Micro or Nano – That is the Question

At that time, everything was better – or? After all, we had at that time a uniform standard size SIM card that fit into each device. But today it all looks different: in addition to the standard size (the so-called mini-SIM) there’s still the Nano-SIM in addition to the micro-SIM and we really must take care to fit our existing map in the new smartphone.

But what exactly is actually a mini, micro – or nano-SIM? We give you also an explanation of how you can cut a SIM card may be too large to fit in your brand new smartphone next to a short explanation of the different form factors. Who even doesn’t dare to cut to size, can request a replacement card in the appropriate format with its operator course (usually for a fee).

The Mini-SIM

The mini-SIM should be obvious to anyone who already his own called a cell phone during the pre Smartphone. The map is 25 mm long and 15 mm wide, with a thickness of 0.76 mm. The mini-SIM is currently still the usual SIM card, which gets you by network operators. However, due to the ever more compact construction of newer smartphones this circumstance changes slowly but surely.

The Micro-SIM

As a third form factor card known, the micro-SIM is a smaller version of the mini-SIM. Their dimensions are 15 mm long and 12 mm wide same thickness, like the mini-SIM card. Technically there are no differences between the micro and the mini-SIM – only the frame around the chip around is narrower.

The Nano-Sim

With only 12.3 mm long and 8.8 mm wide is the Nano-SIM – as the name suggests – the smallest card in the SIMs. Actually it is even thinner than its two siblings, only 0.67 mm, because here the frame is completely missing. First introduced was the Nano SIM iPhone 5 with the Apple and takes its place today in many modern smartphones.

Make Out Mini Nano

Meanwhile the network operators offer pre-scored the SIM cards. I.e. You will receive a credit card-sized card in the SIM card is located. They break out, you have a mini-SIM card. Then it can be from the frame separate two more times at the punched points, to obtain either a micro – or just a Nano-SIM.

Now has a new SIM card to the hand but not everyone directly, but has still an older map, which therefore comes without punching. There are now two possibilities: either to order a replacement card in the right size with its operator or you cut along the card itself.

Cut Your Own

Who dares to even manage to cut the card, find numerous instructions and usually also direct templates to print out on the Internet. But be careful: just older SIM cards often are not suitable for cutting, because the chip is usually slightly larger than in modern cards.
