Description WiderThan is opening up the phone lines to entertainment, without the lines. The company provides integrated digital entertainment to communications service providers worldwide.

The company supplies its content to wireless service providers through an application gateway that authenticates and authorizes access based on carrier contracts. The gateway also automatically clears subscription charges for usage, transactions, and revenue sharing agreements between WiderThan, the carrier, and content providers.
