How to make your own Micro-SIM or Nano-SIM Card

Despite what you may wish to say about Apple, they are truly the real innovators in the Telecoms World when it comes to smartphones. Their Apple iPhone with its introduction of Capacitive Touch Screen that removes the physical keyboard has become the much envied and copied smartphone tech in the UE (User Equiptment) world.

And now with 4G Internet available on both Digicel and LIME and my guide How to Access LIME or Digicel’s 4G Internet using an unlocked 4G LTE Modem Dongle, smartphone or Tablet you have more reason to leave the “IN” Crowd still banging away at their semi-extinct Blackberrys and join the “smart” crowd with you newly imported smartphone.

Possibly the only other thing that’s stopping you is how to import your Data from your beloved BB to a smartphone such as the Apple iPhone or Samsung Galaxy SIII, for which I have an article in the pipeline.

But very few people are aware that Apple is also the innovator behind yet another piece of tech: the Micro-SIM (Subscriber Identity Module). The Micro-SIM in the Apple iPhone 4 increases the space inside of the Apple iPhone to pack more electronics.

Now with the recent launch of the Apple iPhone 5, Apple has introduced their own innovation, the Nano-SIM (Subscriber Identity Module) standard, which they’d been argueing with the ETSI (European Telecommunications Institute) since 2011 and more recently in March 2012. The Nano-SIM allows Apple Design Engineers to increase the size of the battery to maintain the Battery life on their Apple iPhone 5 that’s now packing 4G LTE. Other smartphone manufacturers such as Samsung have copied into their No.1 selling smartphone, the Samsung Galaxy SIII  now that Apple’s gotten its way with the ETSI for their new standard.

The new Nano-SIM Standard was much rumoured before the launch of the Apple iPhone 5. Now that it’s a ETSI Standard, expect to see the Nano-SIM Standard being copied b y both smartphone and Tablet makers alike

The Micro-SIM, however, is really the where it all began. It’s the same Mini-SIM Card (Subscriber Identity Module), found in regular phones without extra plastic. Which means of course what follows is a DIY (Do It Yourself) for the Micro-SIM and then the Nano-SIM.

You’ll need:

  • Mini-SIM to Micro-SIM or Nano-SIM  Conversion Template
  • Sharp Pair of Scissors
  • Fine Sandpaper
  • Micro-SIM Cutter

The instructions are simple enough:

  1. Go and download the Mini-SIM to Micro-SIM or Nano-SIM  Conversion Template and print the template at 100% size
  2. Follow the instructions on the template, taking care to use a very sharp pair of scissors
  3. Use fine sandpaper to soften up the edges of the newly-minted Micro-SIM Card and try to fit it into the SIM Card Slot

Alternately you can also go to the link at for a Micro-SIM Cutter for the Apple iPhone 4S and using your Scotia Visa Debit Card and the instructions in How to use Scotia VISA Debit Card Online you can purchase one for only US$3.50. It comes with two (2) extra adaptors, should in case you decided that you want to switch back to a Mini-SIM.

If you are moving towards the Apple iPhone 5, you’ll need to go to the link at for a Nano-SIM Cutter that costs only US$4.95. Stocking up on some Nano-SIM to Mini-SIM or Micro-SIM Adaptors from Amazon is not a bad idea either, as at this point you can even go into business of converting between the different SIM Card Standards.

That’s it! No need to pay anyone money or waste gas or bus fare to go to the Telecom Provider to have your Mini-SIM cut to a Micro-SIM Card or a Nano-SIM Card for you to enjoy your new smartphones. With this DIY, you can do it at home and even make a little bit of a business of it… least until your friends read this article!
