Who has all the material forms on the communication line, preferably with additional pictures?
The user through the 1/2 line also has a secret purpose, if the selection of "2 lines", can prevent the theft of the phone, (others take your mobile phone call does not go out, others do not know your general settings, you said network problem). Setting to "line 2" will not affect the reception of the phone. (equivalent to: call barring) limit all outgoing functions.
The design of mobile phone line is as before (imagine) mobile phone development should be born, is a mobile phone can have dual line (double number), selected by the user while using a different 1/2 line number, but this design finally operators did not develop this aspect of the business, the only line 1 line. You cannot use 2.
Generally speaking, mobile phones have two "communication lines"". "Line 1" and "line 2"".Generally we will set it as "line 1", the mobile phone can be used normally, if set to "line 2", then there is no network available.
