The carrier knows little to nothing about the phones.
Samsung is who you need to contact. It could be a software issue or a physical issue.
If a reset doesn't fix it, Samsung will remove the OS not reflash it, then put the OS back on. That fixes numerous things that a reflash or reset will not fix. They will also check everything else.
I had a Note 2 that wouldn't take the unlock code. I sent it to Samsung, they removed the OS put it back on and the unlock code worked fine. Only Samsung can remove the OS.
