SIM Card Installation
Installing the SIM Cards
Take care to insert valid SIM cards in your phone before using the device. The SIM cards save the parameters
required for communications and personal information, including PIN (Personal Identification Number), address
book, messages and other system services additional.
Since the phone supports two SIM cards, when registering a mobile phone number, you can apply for two separate
phone numbers, two different mobile phone network service providers and thus obtain two SIM (Subscriber
Identification Module) cards.
With these two SIM cards, you can use all the features of your phone.
Warning: do not deform or scratch the SIM cards nor let it contact static, dust or moisture. If it is lost, please
immediately contact your network operator for help.
Before SIM card installation, please switch off the mobile phone. The SIM cards must be inserted in the back of the
phone, after removing the battery. Insert the SIM cards in their slots with the gold contacts facing down. Insert the
main SIM card in the SIM1 slot and secondary SIM card 2 in the SIM2 slot. See the diagram below.
Note: if a SIM card is inserted into the SIM1 slot only, then only the host works; likely, if a SIM card is inserted into
the SIM2 slot only, then only the slave works. When two SIM cards are inserted into the SIM1 slot and SIM2 slot
respectively, you can choose work mode freely as you wish.
Note: as the SIM card is small object, keep it out of children’s touch or prevent children gulping it!
