1300 numbers are Local Call Numbers, where the caller is charged a local call rate from any Malaysian phone line. Calls to 1800 numbers are free, including from a mobile, which is why they're often referred to as Toll Free Numbers.*
1800 and 1300 numbers are virtual numbers that are routed to an answering point that can either be a landline or a mobile number. Depending on the business requirements, the number can be routed to one or a range of answering points. Being virtual numbers means they're fully portable, making them a perfect choice for growing businesses that may be moving premises or expanding.
