How to cut your SIM card

Not all SIM cards are the same and the size you need depends on the type of phone you have. However, it is possible to cut a standard SIM card to one of the smaller sizes, or even cut a micro SIM to nano SIM dimensions.

However, it’s important to remember that a SIM card is effectively a little circuit board, so if you cut it incorrectly you may render it useless. That’s why extra care and attention should always be taken – and why many people will opt for a micro or nano SIM cutter.

These can be bought online relatively cheaply and will help you make sure you cut your SIM card right. If you want to go ahead and do it yourself without this handy tool though, check out our guide below.

What you’ll need to cut your SIM card

Before you think about how to cut your SIM card, you should be absolutely clear about what size you have and what size you need. Our SIM card size guide [link] features the dimensions for the standard (or mini), micro and nano SIM sizes, and is a great place to refer to before you get out your scissors.

Once you are sure what size you are looking for, you’ll need a few things:

  • A good pair of scissors
  • A sharp, thick kitchen knife
  • A printable SIM template [link]
  • A roll of clear sticky tape

Cutting your SIM card safely

First off, print your SIM template [link], making sure your printer settings don’t alter the template size at all (for example, don’t use the ‘fit to page’ option). Once you’ve printed it off, place your SIM card on top of it, ensuring it is aligned perfectly with the guidelines.

Next, secure the SIM card with clear sticky tape, so it remains firmly in place but you can still see the guidelines. Then, take your kitchen knife and press down along the guidelines, the idea being you make a clear indentation to cut along with your scissors.

Finally, take off the tape and get rid of the template – you should have a sim card with clear lines showing the sections you need to cut off. Remember, because you’re cutting through thick plastic and trying to avoid the delicate circuitry of the SIM, your scissors must be strong and sharp – and you should cut in lines that are as slow and straight as possible.

Once you’ve carefully cut of the excess plastic around the circuit board, you should have a SIM card that fits snugly into the tray of your phone or tablet. And if you’ve kept to the guides, all you need do next is boot up your gadget and wait for it to connect to the network.
