Well, on Verizon, it's $30/month for "unlimited" data. Since the average Verizon uses 421 MB per month, I'll go with that. Your rate, multiplied for 1GB of data, works out to be $16.90 US.
So the average Verizon users pays almost twice as much as you do, for less than half as much data. I can only wonder what the hell those who only use a couple hundred MB/month (or less) are thinking.
I'm a long time Verizon Wireless customer, and only recently became interested in a smartphone, due to Android and Droid. I thought for sure there would be some kind of data plan for families, that would be reasonable. There isn't.
In order for my wife and I to both have a smartphone, and assuming we'd both be average users (and my wife would be well below average), Verizon wants me to pay $60/month for 842MB/month.
Not just no...but hell no.
I even called them, and was told (in a long winded, roundabout, very polite way) that if I wanted the phones, I had to pay the data.
Apparently, people are falling over themselves to pay this money, because the only other option they give is $9.99/month for 25MB of data, on their 2nd tier "3G Multimedia" phones.
