How is SLYNUMBER different than a business phone service?

SLYNUMBER is different than business phone services in that it is an app that lets you choose a local phone number to make phone calls and send text messages. You can still take business calls and customer calls from your cell phone but without subscribing to a phone plan from a service provider. Use SLYNUMBER for the call management of all your business needs/business communications and ditch the landline
