Mini SIM
Important: This device is designed to be used with a mini SIM card only. Use of incompatible SIM cards may damage the card or the device, and may corrupt data stored on the card.
Note: Switch the device off and disconnect the charger and any other device before removing any covers. Avoid touching electronic components while changing any covers. Always store and use the device with any covers attached.
Insert the SIM card
- Put your fingernail in the small slot at the bottom of the phone, lift and remove the cover.
- If the battery is in the phone, lift it out.
- Slide the SIM card in the SIM card slot.
Insert the second SIM
If you have a dual-SIM phone, slide the second SIM in the SIM2 slot. Both SIM cards are available at the same time when the device is not being used, but while one SIM card is active, for example, making a call, the other may be unavailable.
Tip: To find out if your phone can use 2 SIM cards, see the label on the sales box. If there are 2 IMEI codes on the label, you have a dual-SIM phone.
Insert the memory card
- If you have a memory card, slide it in the memory card slot.
