Abstract: A system and method for call routing among multiple service providers is disclosed. In one aspect, a call dialed by the user is directed to a call routing broker for determination of a cost effective or otherwise best call option for the user. If an option to place a call through a service provider that does not incur extra charge and does not accrue data or minutes against a plan quota, the call will be placed through that service provider. If only an option to place the call through a service provider that does not incur extra charge but does accrue data and/or minutes is identified, the call will be placed through that service provider. If only an option to place the call through a service provider that does incur extra charge, the call will be placed through a service provider selected based in part on the best rates.
