SIM Card Installation
Installing the SIM Cards
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. 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.
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.
