how can i "open-line" my nokia 5300 by myself?

[lancebaggins]

my nokia 5300 came from canada and i live in the philippines.. so basically,it can't accept networks from my country.. my solution is to make its line open or "versatile" (can accept any sims)..but i want to do it myself.

you can openline your phone through codes. you can get the codes from Prounlocking.com or from your service provider itself.
