As the 25mm x 15mm Mini SIM card needs to sit in a slot designed to accommodate the smaller 15mm x 12mm Micro SIM card this tool can be used to reduce the overall size of the card.

A SIM card cutter tool is designed to easily and precisely convert an older Mini SIM card into a Micro SIM card by simply removing surplus plastic from the chip.

With the low price of buying a cutter online this is the cheapest solution without needing to buy a new SIM card from your service provider.

We recommend buying a Micro SIM card cutting tool which includes free Mini and Nano SIM card adapters as this will enable you to switch between older cellphones which take different SIM card sizes. [8]

What does a SIM card adapter do?

A SIM card adapter or SIM converter allows you to insert a smaller card into the adapter, the adapter can then be inserted into a slot in any device designed for a larger SIM card. Inserting a smaller SIM into the adapter will increase the size so it can accurately fit to align the contacts on the card to touch the phone pins.

Should you risk using scissors to cut a SIM card to fit the iPhone 4?

Do not attempt to use scissors to cut a SIM card as it risks bending the edges and damaging the copper surface on the card, instead we suggest using a SIM card cutter which is designed specifically for the task.

There is a danger that damaging the copper between the SIM card and phone may result in reduced signal strength leading to dropped calls, unstable data and higher battery drain because of the phone repeatedly scanning for a new signal. This article on why you shouldn’t cut a SIM card with scissors contains more in-depth information.

If you have inaccurately cut your SIM card with scissors and are now encountering problems with the iPhone 4 then you may need to contact your network provider to send a replacement card. Using a card which has been cut with scissors can potentially invalidate the warranty therefore Apple may reserve the right to repair your iPhone 4 caused by damages of inserting a poorly cut SIM card.  [9] [10]
