Nokia Lumia 1520 User Manual page 7

Important: Your device uses a nano-SIM card, also known as a nano-UICC card. Use of
incompatible SIM cards, or use of SIM card adapters, may damage the card or the device, and
may corrupt data stored on the card.
Tip: Use the SIM card holder tool to unlock the SIM holder. If you lose the tool, you can use a
thin paperclip.
Make sure your phone is switched off.
1. Hold your phone face down, and push the tool into the hole until the holder is released.
2. Pull out the holder, and remove the tool from the holder.
3. Put the card in the holder with the contact area face up, and push the holder back into your phone.
