How do I make my SIM card bigger or smaller?
How many SIM card sizes are there?
Let's start at the beginning: how many SIM card sizes are there? There are 3 different sizes: mini, micro, and nano. The sizes can be easily recognized by the size of the gold-colored circuit, relative to the size of the plastic shell. The 'standard' SIM card is the largest and contains the most plastic. The micro card is the second largest variant, while the nano card is the smallest one. This SIM card only has a small strip of plastic surrounding the circuit.
Help, my SIM card is too big
Nowadays, most SIM cards are in a kind of mold. You can choose the size SIM card you need there. Do you have an older SIM card? You can cut it to size, but you can damage your SIM card while doing so. Instead, contact your provider and ask for a SIM card with the correct size. This usually costs between 5 and 15 euros. This way, you'll know for sure that you won't damage your SIM card.

This can be solved relatively easily by using an adapter. Simply place your SIM card in the adapter and insert it into your phone.
