That damn 2 Mb

To test the LTE 4G Verizon data usage, I intentionally left my New iPad in a WiFi area, and see if the usage will go up.  After a full work day, I checked the usage, and found that it goes up from 55Mb to 57Mb.  What the HELL!  Like, how come the data usage will go up when I didn't do anything.  The only thing I can think of is that I brought my iPad with me with going to the kitchen, but even then I was like reading a eBook or something.  This got me so pissed, and decided that I should turn off Celluar data access all together until I really need to.  That really sucks, because when I used my 3G AT&T unlimited data plan, I don't have to think so much.  I just use, and get on my life.  This damn 4G totally sucks.  I only benefit is Personal hotspot.  That's it.  Piece of shit Verizon 4G.
