When registering mobile phone number, you
can apply for two different phone numbers, two
different mobile phone network service providers

functions of your mobile phone. The SIM cards
save the parameters needed for communications
and personal data, including PIN (Personal
Identification Number) code, phonebook, short
message and other extra system services.
Warning: Do not distort or scratch the SIM card

lost, please contact immediately your network

the mobile phone. The SIM card is installed on
the back of the mobile phone.
