SoftBank Corp. said Thursday it will provide from April at the earliest a new cut-rate price option for smartphone customers who do not talk for long periods on the phone nor use a great deal of data.

SoftBank is the first among nation's three major mobile phone carriers to unveil a low price option in response to the government's call to reduce mobile phone prices for light users.

The new plan, with a monthly fee of ¥4,900 excluding tax, is 24.6 percent lower than SoftBank's current cheapest option of ¥6,500 for fixed-rate voice calls and data downloads.
