Metered plans give you a set number of minutes to use across an unlimited number of extensions in your account, or you can also go with a plan that gives you unlimited calling for one low rate per extension. The choice is yours!
All plans are subject to fair use restrictions. For more information refer to the Terms of Service section 1.5.
Each additional text sent and received that is over your allotted plan will incur a $0.005 fee.
