Carriers such as Cingular Wireless have been selling unlimited e-mailing and Web surfing on popular BlackBerry pagers for about $40 a month. Earlier this year, Verizon Wireless introduced an "all you can eat" Web plan for $99 a month. Sprint PCS is now offering three months of unlimited downloading as an incentive to buy a Handspring Treo.

Later this year, T-Mobile will set a new low-price mark by selling a combination impact-absorbing co-molded case for iphone 6 plus/iphone 6s plus phone and data device called a Sidekick for about $200, less than half the cost of comparable devices, But what has also generated interest is the cost of using the device: Unlimited Web access, including e-mail and instant messaging, with 200 minutes of phone calling will run about $40 a month, according to sources, "Competition is going to force all the carriers to eventually offer the same kind of plans," said Alan Reiter, president of an industry consulting company called Wireless Internet & Mobile Computing, "Carriers are being dragged into 'all you can eat,' kicking and screaming."..

Although some industry sources say the move to one-priced wireless Web access may spread slowly, even a gradual shift could increase use and prompt companies to offer more content geared toward matchbook-sized screens. And better content could lead to more consumers finding a reason to surf while commuting and lying on the beach. Online use, for example, was relatively modest in the 1980s and early '90s when providers charged flat rates as well as additional fees for access to particular content or when a certain amount of time was exceeded. In the mid-1990s scores of small Internet service providers began charging $15 to $25 per month for unlimited Web access.

America Online jumped on the bandwagon in 1996, a move that sharply increased its subscriber base, The target customers for mobile services are people like Greg Kirsch, a lawyer and partner at Needle & Rosenberg in Atlanta, He's used the BlackBerry pager for about two years impact-absorbing co-molded case for iphone 6 plus/iphone 6s plus to read his e-mail on the go, Last week, he bought a Treo from Sprint and says he's enjoying the unlimited use of the Web on the device, But he wishes Sprint would permanently offer the plan after the three-month trial period..

Some carriers, such as Cingular Wireless, limit the amount of spectrum used to transfer data such as e-mail to prevent jams in their networks. They prefer to reserve most of their wireless network for voice callers. After all, they make nearly all their revenue handling phone calls. "Carriers are afraid, with some justification, that people are going to start downloading giant files if they don't have to pay on the metered basis," Reiter adds. Once they do, "there goes your network.". Most carriers have instead settled, for now, on the same kind of tiered-pricing plans that broadband providers are adopting, said Keith Waryas, an analyst with IDC.
