Increased charges on wireless connections on tablet computers may force consumers to use free Wi-Fi rather than invest on cellular network along with the high price of the network, said a report.

The result could further drop the sale of tablets supporting cellular, potentially making operators less relevant as tablet distributors than electronics stores.

The tablet's more natural point of sale is retail, Nvidia Chief Executive Jen-Hsun Huang told the Reuters Global Technology Summit this week. The question is whether carriers will find a reason to bundle tablets with other services and create a subsidy model that is really appealing.

With the limited cellular Web use on tablets by charging for each gigabyte (GB) of data downloaded, the sale of tablets with cellular connections falling as low as 30 percent of the total in 2015 from about 60 percent in 2010, Reuters reports.

The mobile service providers are looking for ways to reduce the charges of wireless connections on tablets.

France Telecom FTE.PA said it’s soon going to change the prices. Orange, France Telecom's mobile service, is looking at offering a data plan shared between smartphones and tablets. Verizon Wireless said it will eventually change the price though it did not mention any timeline.

To limit the sale of tablet connectivity to a particular time period would be another pricing policy, sa people use tablets more sporadically than smartphones.

David Owens, vice president for product development at Sprint said, What you'll see is the ability to buy sessions -- a day, a month or a week pass.

John Stankey, AT&T's head of business solutions said AT&T's tablet plans are already very consumer friendly because while the operator does not pay a subsidy to reduce the price of the device, neither does it require a long-term contract.

If the carriers continue to charge high, tablet makers who are rivals to Apple’s ipad, like Samsung Electronics, Motorola Mobility and computer makers like Huawei Technologies and Dell Inc will have a tough way to go.
