The include six plans that range from 400 to 4,000 anytime minutes, with unlimited data, and are priced from $70 to $230 a month. Users can pool the minutes in a business, the Sprint spokesman said.

While some buyers might object to the monthly voice and data prices, Sprint said users could potentially save hundreds of dollars over its competitors.

Monthly data pricing plans won't be going down any time soon for smartphones, analysts predicted, although there have been some increases in the amount of data downloads allowed for the same price in mobile broadband service for Verizon Wireless, specifically for laptops and netbooks.

Carriers have no incentive to lower voice and data plans for smartphones because they don't want to have rates so attractive that users "saturate" their networks, Gold said. Still, he said pricing for voice and data won't be the main reason users buy the Pre or hold off.

"As for the Pre being that good, it remains to be seen," Gold said. "It seems to be a very competent device and has some unique features, but it basically needs a heavy data plan to get all the online apps it needs to run, so if Sprint can't provide the level of service and reliability users expect, I am sure you will be hearing complaints like the ones voice about AT&T's 3G service early on with the iPhone."
