Update 2: How to insert SIM card in iPhone 5
Apple has announced the next-generation iPhone ‘iPhone 5‘ which is just 7.6mm thick, the world’s thinnest smartphone according to Apple. To make this happen, Apple has switched to a nano-SIM card in new iPhone 5, which is 44% smaller than a micro-SIM. Certainly, you wont be able to use your normal SIM or Micro SIM card in iPhone 5. And nano-SIM being a new standard introduced by Apple, wont be available anytime soon with all the carriers.
As stated by ETSI, The fourth form factor (4FF) card aka Nano SIM will be 40% smaller than the current smallest Micro SIM card design, at 12.3mm wide by 8.8mm high, and 0.67mm thick. It can be packaged and distributed in a way that is backwards compatible with existing SIM card designs. The new design will offer the same functionality as all current SIM cards.
Comparing the dimensions, there is a substantial difference in the sizes of Micro SIM and nano SIM. Even if you manage to cautiously chop down your current SIM card using a knife or a pair of scissors, then it still wont work because the nano SIM’s thickness is reportedly reduced by 15%.
Here is a video tutorial that describes ‘How to convert a Micro SIM into a Nano SIM‘ but it’s not a foolproof way and there are high chances that you might spoil your SIM while doing it. Also, the converted SIM hasn’t been tested yet in iPhone 5.
The nano-SIM tray on iPhone 5 is placed similarly, on the right side of the phone. Simply use the SIM eject tool or a paper clip to remove it and place your SIM card.

Apple has launched the iPhone 6 that supports Nano SIM card, just like the iPhone 5 and iPhone 5S. The Nano SIM card slot on iPhone 6 and iPhone 6 Plus is located on the right side of the phone. The Power button is now placed on the right-hand side to make it easier to access, as the new iPhones are significantly bigger in size with screen-sizes of 4.7″ and 5.5″. The SIM insertion procedure in iPhone 6 is same as seen in earlier models. Users simply need to use the SIM eject tool or a paper clip to pull out the SIM tray and place their SIM card. You might need to apply some force until the tray pops-out.
