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
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.
Note: Pre-installed system software and apps use a significant part of memory space.
