DATA Usage TYPE showing ADTM instead of mobile one line only
Hi. On my at t app I can see current data text usage etc. One line has used an extraordinary amount of data this month. On the DATA usage type its shows ADTM instead of mobile. No other lines show this and never has before. I've called at&t, I've googled this and found NO answers. At&t representatives dont even know. Again, this is showing on data usage TYPE. Does anyone know what this is?
