No data usage showing for two months

[gradynyc]

Some how one of the kitchens stopped data from posting for two months. I'm trying to recreate it. I went from stock 6.1 rom - dcd3.2.5 to 3.2.6 then when i went to the 20xxx kitchen (can't remember). I posted no data for two months. I thought it was sprint messing with my data I thought they grouped it with one of my other phones. But after two months of wondering and thinking they took away one of my phones data. I flashed back to stock 6.1 and the data is racking up again. I had data before that but it wasn't posting. Any ideas why?
