I have the $30/month unltd data package. However I heard that if wifi is off, everything you do that requires 3G will add to the phone bill. I just checked my usage in my phones settings and it said I sent 147MB and received 1.2GB. I'm not sure what all this means. I had the current bill payment texted to me from the Verizon services and it said $351. Could this be all of the phones from our bill added together or is it just me? There are three other phones, all with the $30/month data pack.
