I just switched from Sprint to Verizon about a month ago & got the new iPhone5. I got a message Tuesday saying we used 75% of our data & now today we are over our data usage... So I looked to see all the different times we've been charged for using data & noticed that well over 60% of the time it was while we were connected to our WiFi account at home. Is anyone else having this issue? How can I make it stop? I think it's ridiculous that we can get charged for data when really you're using WiFi!!! Any insight that anyone can give would be great b/c when I called to ask the girl really didn't have many answers for me. She told me to call Verizon Fios & see if there is something wrong w/ my router & if that doesn't work go to a Verizon Wireless store & see what they say. This is total & complete crap if you ask me!
