I'm trying to explain data usage to my 62yr old sis in law. This month in 16 days she has used over 12gb of data so far. She found a Sims like app that she has spent a lot of money on upgrades that she didn't realize she was doing. Now I need help explaining even metro's unlimited data has a reasonable use limit also. NOTE TO MODS, If there is a better place for this go ahead.
