Hey, why did my plan change? My wireless router went from 10 G at 4 LTE G to 15 G at 4 LTE G. Sounds great, more for the same price. BUT after I have used my 15 G my download speed drops from 4G to 600kbps not 3G. Best I can find out, there's a significant difference between 600kbps and 3G. Also, somehow I used the additional 5G in less than 3 days. I haven't increased my time on the computer so I'm flabbergasted by all of this. Any thoughts?
