Closed Sim card problem

[ChocoMartinPH]

Good day! Ask lang po sana ako kung anu ibig sabihin ng pag switch ng sim card 1 and 2? Samsung duos kasi fon ko.



Salamat!

For me, it is just a way of switching from one network to another.
Giving you a chance to choice what network you refer in accessing the internet through mobile data.
