So I bought a used S3 about 3 weeks ago and I unlocked it with at a local shopping mall. I got my old contract on it and it worked perfectly fine until yesterday. I installed Cyanogenmod on it because a friend of mine recommended it for me. After having played around with the installed software (didn't encounter any problems whilst installing it) I decided that I liked the stock OS better so I downloaded the stock file (JellyBean 4.3) and I reinstalled my backup on the device but I am now having a big issue for me: I cannot seem to be able to active the Network Data, I use it a lot and it is really bugging me. I think I might have installed the "Telus" version of Android JellyBean 4.3 but remember reading that it was compatible with Koodo Mobile and their networks. Help?
