What does a SIM card adapter do?

A SIM card adapter or SIM card converter allows you to insert a smaller card into the adapter, the adapter can then be inserted into a slot in any phone designed for a larger SIM card.

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 [10] 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 [9] 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.
