What model number does my s6 edge cellcom fall under

I have a galaxy s6 edge on cellcom model number is sm-g925r6 build number is LRX22G.G925R6WWU2A0F2 and baseband version G925R6WWU2A0F2 and hardware version G925R6.01 . I am having an issue finding support I'm thinking because cellcom isn't a major carrier. I want to know if there is a model number similar to mine so I can update it without messing things up. I went to the website and they don't have my model number. There is ones with te same beginning part (sm-g925r6) but the numbers after that don't match on any of them. Any advice? You can Poston here or pm me.
