5. The phone uses a "Dual card dual standby single-pass" design, with means the two card
in the phone cannot be used in the same time for voice service nor data connection service.

design, which can significantly improve the battery life and energy efficiency. The user is
encouraged to consult local operators to enable services like "Missed call reminder",
