How To: Convert Your Regular or Micro SIM To a Nano SIM For iPhone 5

By  |  0 Comments

The iPhone 5 is 18% slimmer than the iPhone 4S. In order to reduce its size, Apple had to completely change previous technology – such as replacing the 30-pin dock connector with the all new “Lightning connector” & further reduce the size of existing components, a fact you will notice when you realize that your tall new device does not have enough room for your old standard SIM or Micro SIM card; the iPhone 5 now uses an even tinnier Nano SIM card.

There are 2 ways of getting yourself a Nano SIM card. The first thing you could do is visit your wireless provider’s local store & get them to replace your old SIM with a Nano SIM card, or you can follow our guide & turn your SIM into a Nano SIM from the comfort of home.

The new iPhone 5


Our guide is straightforward & very simple. You’ll require the following:

  • A working printer
  • A4-sized paper
  • Some Tape
  • A Ruler & marker
  • Sharp Scissors
  • Sandpaper or a file (Nail File works fine)

When you have all of these items, you have our permission to cut (your SIM card) :p

1) Print the PDF from here at a 100% scale on an A4 page.


2) Place your current SIM card (either Mini or Micro) on the templates designated area. If you have a Mini SIM, place it on the 2nd highlighted area. If you have Micro SIM, place it on the 3rd & last.

3) Firmly stick your SIM card to the highlighted outline area using some of tape. Be sure to align all the edges correctly.

4) Use the ruler & your marker to accurately mark the five lines along where you have to cut.

5) Time to Cut it! Be very careful, Please!! Take things slowly. You will damage your SIM card if this is not done properly.

6) Now smooth the edges of your freshly cut Nano SIM using sandpaper or a nail file. Again, be very very careful during this step as it could damage the SIM card’s chip if you sand the SIM down more than it needs.

Bazinga!! You now have a Nano SIM that should, “technically”, work with an iPhone 5.

This is not a completely foolproof method. There are chances that you could permanently damage your SIM card, so proceed here with extreme caution. If you do not have any backup SIM cards to use with your current phone, we highly suggest going through the effort of visiting your local cell store; it’s better than being screwed & without a phone. Burrilliance & DBM will NOT be held responsible if you damage your SIM card following this guide.

Enjoy your new Nano SIM card!!
