iPhone 5 Owners Might Be Able to Cut Micro SIM to Nano SIM Adam Mills09/17/2012 With a little patience and some work, it appears that iPhone 5 owners may be able to trim a Micro SIM down enough to potentially fit inside the iPhone 5’s Nano Sim slot. One of the biggest questions leading up to the release of the iPhone 5 on September 21st is whether or not iPhone 5 owners will be able to trim down a Micro SIM card to fit into the iPhone 5’s new Nano Sim card slot.Advertisement With the iPhone 4S, owners have been able to trim down a Sim card to fit into the iPhone 5’s Micro SIM card slot which allows the device to work on carriers like T-Mobile. T-Mobile’s network is currently home to over a million users who use their iPhone like this.

The site was able to slim down a Micro SIM to 0.70mm which may be a size that the iPhone 5 Nano SIM tray permits which means that it might be possible to trim down the Micro SIM to fit inside the iPhone 5. All it will take it seems is a bit of sanding and possibly, some gagging due to the horrid smell that comes with the dust that is omitted.

The slimmed down Micro SIM card did still function inside of the HTC One X which is a good sign. So, while there is a possibility of this working, nothing is confirmed yet. Of course, those looking to grab the iPhone 5 on T-Mobile may just want to wait until October, the month that the carrier is rumored to be releasing Nano SIM cards for iPhone 5 owners to use. These cards will allow owners to run the iPhone 5 on T-Mobile’s network.
