Verizon Wireless MiFi I bought a 4g Jetpack at Walmart in North Myrtle Beach, S.C. 29582 and a prepaid card for 3GB of data usage which was represented to be only downloads or uploads. I have since found out you data usa New York, New York

That same happen to me and I received a Bill of $1056 for 7 days of Internet usage. If you think about it that's a year worth of phone service! Just the thought of charging someone that kind of money should be illegal. 

not only that,  verizon must have switches in their programming, for my jet pack is always slowing itself down and loosing signal to 1 bar at the event, of, a certain amount of time.   One moment I have 3-4 bar signal, then all of a sudden, it is only one bar.  And color changes to purple.  3 g...   But in the event of speed,  all download speeds are always faster then upload.   Yes, it is fraud.  But, I have not known any ISP provider to ever give you the right thing.  They are all liars.  But this one, takes the  cake, for I know they are with programming the switches of to slow me down, after I have been on for say, an hour.  IF I turn it off and leave it,  for say, 30 min, it will go back to 4 G, and 4 bars.   So, do know, that this is what they are doing to the public...   They are a rip off.  And as soon as I can,  I will go to using someone else, no doubt....   They remind me of the laser weapons on the trade centers, and wonderful daddy bush.
