Which SIM card for iPhone X? This is the right one!

Only one SIM card is the right size for the iPhone X. If you don't get the correct SIM card sent to you by your wireless carrier, simply request a new one or else cut the card yourself.

Right SIM card for iPhone X and instructions on how to insert it

The right SIM card for iPhone X is the nano SIM. If you sign a contract that includes the iPhone X, you will automatically receive the correct card from the mobile operator. If you are yet to sign a contract independent of the smartphone, then you should directly apply for a nano SIM.If you have the right format, insert the SIM card in the iPhone X like this:

1. You will need something sharp, such as the SIM tool that comes with the iPhone X. The SIM card can also be inserted into the iPhone X using a ballpoint pen. Alternatively, however, a ballpoint pen or a bent-up paper clip are also suitable.
2. On the right side of your iPhone X, you will find a tiny opening. Press the button in it so that the card compartment opens.
3. Insert the SIM card accurately and finally push the compartment closed again.

Not the right size: What to do?

There are three different SIM card formats, which differ mainly in size. For the iPhone X, you need the smallest SIM card that is currently available, namely the nano SIM. However, the same chipset is installed on the different formats. Therefore, you have the advantage that you can cut the nano-SIM if you only have a micro-SIM. For many SIM cards, you can simply break out the smaller size thanks to a punch.
