I am in no way a geeky type person that knows the difference between killobytes, data usage etc. i bought the MiFi because I needed internet access for my job. I bought the 4 G right. No one in the store ever explained to me that it was not unlimited, or that when a message states something about usage 50% means you are close to your limit. So, I went over and got a surprising verizon bill for More than $500.00!!... the response from the representative."well, we sent you information,you were close to your limit". YES, to someone who didnt understand that the internet was not unlimited!... so i try to discontinue the service... oh yeah, just try it... contract is until 10/2013. so, whats to be done?... anyone in the same boat?... do we need to take a computer class before buying data equipment...?... what a ripp off.
