How to get your MCC MNC code?

[LichKing]

Hey everyone i am new here and this is my first post. first of all i want to say hi to everyone: "Hi everyone". lol.

i was doing some research on this forum and was able to successfully unlock my nokia 3120 RH-50. the only problem i had was figuring out my MCC+MNC code. i stumbled upon it by accident on a thread that was apparently started by somebody from my country with the same phone and network as me. but the thing is i have no idea how to get that code out of the phone. my country is trinidad and it is not on any of the calculators so i had to use expert mode and type in the MCC+MNC code manually.

the problem is that i know the code for 1 provider in my country but there are 2 others and i was wondering how i could find out those codes. i tried calling them but the support people don't have a clue as to what code i was asking for and i doubt they would give me it anyway.

i already did some searching around in this forum and found the MCC and MNC widely used but i have not seen how to get it. also i saw something else called a mastercode that peaked my interest. whats a master code and how can i get it?

if there is info on another thread then paste me a link so i can go read.

btw i have a nokia CA-42 cable. can that be used with any software for unlocking purposes?

have a nice day all!!!
