If you sign up for service with Verizon Wireless, you can buy an "unlimited data" plan for your Smartphone. This is $44.99 a month.
However, what they don't tell you - you have to call the Psychic Friends Network for this info - is that this doesn't cover both of their wireless networks. See, Verizon has two of them: the Express Network and something called Quick2Net.
Now, even if you know that using Quick2Net will cost you the same as making a regular voice call, it doesn't matter... because every time you reboot the phone, it defaults to use Quick2Net. You have to remember to manually change the network to Express Network every time you turn on the phone.
If you forget to do this - and believe me, I'm the king of forgetting to do this - then the second you open a data connection, you're charged the same as you would be for making a local phone call.
The software I work on - Pocket MSN - opens a data connection and keeps it open, which would normally be free... just not on Verizon Wireless.
Looking at my phone bill this month, I had at least one phone call that cost me over $100. Amazing.
Thank God Microsoft is paying the bill, or else I'd be totally livid.
