Service: Determines the number's features, which can include things like voicemail, call-hunting and tone-driven menu systems.

Plan: The price plan applied to your number and service. Which plan best suits you will depend on your expected call volumes. Choose the 'Bas' (basic) plan unless you expect a high volume of calls.

Don't worry about making the best choice: You can change service and price plan at any time after purchase, simply by contacting our support department.
