The Toll Free Number Service in Philippines has become very much popular in recent days. In it, generally, all the incoming calls are billed per minute to the toll-free 1800 numbers. These toll-free 1800 numbers are only for domestic calls. But you must dial 1800xxxxxxx (where xxxxxx is your number) for generally domestic calls to an 1800 number from a landline or mobile device.
