Converting a MiniSim to a MicroSim for iPad & iPhone 4th Generation
The micro-sim format came to popularity after Apple introduced the iPad with 3G capabilities and instead of choosing the standard mini-sim to provide data-services, opted to use the micro-sim format in this device. But the history of it goes way back till 1998 where it was first mentioned and the final form factor for the micro-sim was decided in 2003.
Now that we have the news that Apple plans to adopt the same micro-sim format for the new iPhone 4G; it's time for us to look a little deeper into what is a mini-sim, what is a micro-sim, how they are different or similar to each other and how can one be converted to the other.
The micro-sim is an updated and miniaturized alternative to the standard sim-module (which is often referred to as a mini-sim). It is smaller to the mini-sim in size but the contact area is almost identical. The chip of the micro-sim is not only the same size but even electronically identical making it easier to convert a mini-sim to a micro-sim by only cutting off the excess plastic. Can be done using a plastic-cutter.
Those planning to get an iPad 3G, which is set to launch in May, or the new iPhone in near future should note that in theory; it's perfectly possible to use a mini-sim in the device by cutting it down to make it look like a micro-sim, since they both of them are designed to work at the same speed, but there might be some restrictions.
Guess we need to wait and find out how this actually works. Power to Apple!
