How many days did it take you to hit 5GB? How much are they slowing it down by? Can you do a speed test and screen shot?
When I was with tmobile, they slowed my speeds down to around 35kbps (4.5KB/sec) which is INSANELY slow. You can't even use google maps, facebook, etc. This used to piss me off SOO much. I was pissed, but I realized that there's nothing I can do about it, so I just got used to the 5GB a month.
If you don't mind me asking, what'd you use your 5GB on?
There's no such thing as "grandfathered in" at metro pcs since we have no contract. Being grandfathered in is a term that's used at contract carriers since they had contracts that were signed that didn't cap data.
I know that guy at metroPCS facebook said "no, you're grandfathered in," but he's lying/doesn't know what he's talking about.
ANYWAYS. Most of you guys aren't going to pass 5GB unless you tether a LOT and/or use your phone as your primary internet source, so don't worry about it. If you do use your phone as your primary internet (I've done that before for a few months), then you just have to figure out how to ration it so that you don't hit your cap. Or pay the extra $10. Or get internet at home.
