I bought a new sim card from Rogers, but when I put it into my Galaxy S5 Neo it said the sim was invalid and that I needed to enter a sim network unlock code. I tried some codes from other forum posts and Rogers, but they all failed and now it says my phone is blocked and that I now need to enter a master unlock code. Please help.
You won't be able to find the code in any message forum (unless of course someone sees your post and has access the unlock code database - usually Samsung or Rogers employees). Never just try random codes unless you're sure that's what the code is for.
As for the code that Samsung or Rogers provides you, by default they're just going to provide the regular NCK unlocking code. Since you've already said that your phone is asking for a master code, that regular code provided by Rogers or Samsung won't work until you get that master unlock code/unblock code. That master code will have to be entered first, for which I believe resets the network unlock code counter. After that, you would still need the regular unlocking code.
