Nokia Lumia 2520 - Can I use a Nano SIM card in my Lumia 2520?

The Lumia 2520 is designed to be used with a mini-UICC SIM card, also known as a micro-SIM card only.

A micro-SIM card is smaller than the standard SIM 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.
