During the good old days, all handphones use standard SIM card with the same size of 25mm x 15mm.
Then, certain high-end smartphones such as Apple iPhone 4, HTC One X, HTC One (M7), Samsung Galaxy S3, Samsung Galaxy S4, etc. started to use a smaller size micro SIM card of 15mm x 12mm. The standard SIM card couldn't fit in their micro SIM card slot, and need to be cut with a SIM card cutter, or you need to request for a new micro SIM card from your telco.
Not long after that, the later high-end smartphones such as Apple iPhone 5, HTC One (M8), Motorola Moto X, etc. started to use an even smaller size nano SIM card of 12.3mm x 8.8mm. Again, the standard SIM card or micro SIM card couldn't fit in their nano SIM card slot, and need to be cut with a SIM card cutter, or you need to request for a new nano SIM card from your Telco.
In some occasion, you might want to convert your smaller SIM card to a bigger one. For example, when your new smartphone is faulty and need to send back for repair, and you need to temporary fall back to your old smartphone which uses a bigger SIM card.
Luckily, there exist SIM card adapters that enable you to convert your smaller SIM card to a bigger one, similar to the concept of converting micro SD card to a standard SD card.
