Nokia XR21 2nd Edition user guide

1. Open the SIM card tray: push the tray opener pin into the tray hole and slide the tray out.
2. Put the nano-SIM in the SIM slot on the tray with the contact area face up.
3. If you have a second SIM, put it in the SIM2 slot.
4. Slide the tray back in.

Use only original nano-SIM cards. Use of incompatible SIM cards may damage the card or the device, and may corrupt data stored on the card.

If you have an eSIM card instead of a physical SIM card, switch on your phone and follow the instructions on the phone. To be able to activate your eSIM, you need a Wi-Fi connection. To purchase an eSIM card, contact your network operator. Note that if you have a single-SIM phone, you can only have one SIM card, physical or eSIM, active at a time. If you have a dual-SIM phone, you can have two physical SIM cards or a physical SIM and an eSIM active at a time. For information on eSIM cards, contact your network operator.
