When someone first buys a iPhone or one iPad 3G, one of the first problems it faces is the difference in the operator’s chip format (called a SIM card) compatible with the device, which is smaller than the conventional size. It is best to always ask the operator for a new chip already in the ideal format, but if you are on a trip or in a situation that really needs to adapt your current SIM for the iPhone, check out this tutorial to cut it yourself.
We have already commented here how it is not very difficult to cut “in the eye” the chip for the format that goes into the iPhone 5, but not everyone has a nano-SIM to serve as a reference. Therefore, they created a schematic way of marking the cuts of both the chip that fits in the iPhone 5 (nano-SIM) and the iPhone 4 / 4S (micro-SIM).
Here’s the step-by-step:
Step 0: Be aware that this process can render your chip unusable. So only do it if you are really prepared to take the consequences.
Step 1: Download and print, in natural size on an A4 sheet, the following document: link.
Step 2: With the help of a durex tape, stick the chip to be cut in the corresponding marking on the sheet:
• the first if you want to cut a standard chip for the iPhone 4 / 4S or iPad format.
• the second, to adapt a standard chip for the iPhone 5 or iPad mini
• the third, to adapt the chip of an iPhone 4 / 4S to the iPhone 5
Step 3: With a pen, mark the chip according to the lines on the paper.
Step 4: Markings made, remove the chip from the paper and cut in the indicated lines.
See on video how the whole process is (in English):
In the video, they suggest that at the end you sandpaper the chip, so that it gets thinner. In our tests, this was not necessary.
With this tutorial, you should be able to adapt your old chip yourself to be able to use it on your Apple device. But remember: it is best to always order a new chip in the right format for your operator, to avoid any problems. The cost of this is between R $ 10 and R $ 15, depending on the operator. ?
