The SIM card is pre-installed in your smartphone. If you need to replace your SIM card, refer to the following instructions.
Turn the phone off, then remove the back cover and the battery (as demonstrated in the previous instructions).
Locate the slot for the SIM card (the lower of the two slots above the upper-right corner of the battery compartment) and gently slide the SIM card out to remove it.
If a microSD card is inserted in your phone, please remove it from the upper slot before trying to remove the SIM card.
