If you don’t want to pay for all calling costs (like you would with toll-free) and don’t want to come across as a local business, then this is your type of customer service number. National/business numbers aren’t tied to a specific location. Customers pay local calling costs and a mobile surcharge isn’t applicable. Calls are easily routed to other destinations, both national and international. They are easy to set up, the accessibility is good and they can be called from abroad.
