Ah. *That* explains where the confusion is.
I'm a longtime regular poster in alt.cellular.sprintpcs and a Sprint PCS customer since December of 2000. I speak with some experience but no authority (I obviously don't speak for Sprint).
PCS Vision phone packages are billed two ways. You can pay $15 per month flat-rate and get unlimited usage with a $10 monthly download credit (which disappears each month if you don't use it) or if you don't want the monthly credit you can pay $10. Or you can pay $0 monthly and pay one cent per kilobyte transferred.
I am not sure about the a la carte, per-KB package, but the unlimited flat-rate package is for Vision use from the handset only, and doesn't allow use of a computer plugged into the handset. For that, you would need to buy a wireless data card from Sprint and get a separate plan.
It's in black and white on the website. Go to PCSVision.com. That forwards you to Sprint's Vision homepage. Then scroll down to the bottom of the page and click TERMS & CONDITIONS - you may need to set your popup blocker to allow popups from Sprint's website, if you have a popup blocker running.
In the T&C popup window, scroll down to "OTHER SPRINT PCS VISION TERMS", which says, and I quote:
Other Sprint PCS Vision Terms. You will not receive voice calls while using Vision. Vision is not available for use with server devices or host computer applications, other systems that drive continuous heavy traffic or data sessions, or as substitutes for private lines or frame relay connections. Unlimited Vision plans/options may not be used with Sprint PCS phones or smart phones being used as a modem in connection with other equipment (e.g., computers, etc.) through use of connection kits or other phone-to-computer/PDA accessories, or Bluetooth or other wireless technology. We may terminate services without notice for any misuse. You may have access to certain games, ringers, screen savers and other items on our Vision site ("Premium Services") that are available for an additional charge. You will be billed for Premium Service purchases on your Sprint PCS invoice based on the charges as specified at purchase. Subject to the terms of the content purchased, we may delete premium and non-premium items downloaded to any storage areas we may provide, including any pictures, games and other content. We may limit the amount of Premium Services you may purchase in a specific timeframe (month, week, day, or other time period).
