A couple of months ago I upgraded my old phone to a Razor Maxx, but kept my original unlimited data plan. Until a few days ago, I was getting really great download rates, 15,000 - 20,000 kbps. but in the last few days, the max speeds have fallen to 200 - 500 kbps, maybe a 95% decrease. I'm not a big user, never more than 5 Gigs per month.
What might be going on, guys? Any ideas or advice?
