I recently was changed from unlimited data plan to 10 megs per month. Because my new phone was 4g and they took away my unlimited plan. I use my free mobile hotspot to link to my laptop at work. I believe I use normal amounts of data per month half a dozen videos streamed nowhere near 10 megs. But I have been at or over over 10 megs at the end plans Cycle! my number 1 day 1 data usage is the mobile hotspot?? Please explain to me whether or not that mobile hotspot uses more data than using let's a PDA.net to transfer my internet service to a different machine?
