I have a GS3 and there's a setting in it that I can set to turn off my data so as to not go over a limit. I have unlimited data so thankfully I don't have to use it, however... I got both my parents a ONE X as presents and they do not have unlimited data, I got them set up with a 300mb a month plan. I doubt they will use it up but just in case, is there a similar setting in the ONE X that I can set to disable mobile data if they ever hit that 300mb mark? I'm paying the bill lol Thanks!
