Link Any Mobile Phone to Vonage Service

Our feature, previously called Extensions, has been integrated into your Vonage service and works as it did before. You will now see this referred to as your "linked mobile number."

Link your Vonage service to up to two U.S. mobile or landline phone numbers. When you use an Access Number and your Security PIN to make a call from a linked phone number, it is billed at the same low rates as your Vonage home phone. For example, if a call to an international location is included in your calling plan, calls made from your linked phone to that location are also at no cost.

Have an iPhone or Android? Link your Vonage service using our Extensions App and make and receive calls on your smartphone. With the Extensions App, you have the option of using your Vonage service over Wi-Fi, which is useful in poor coverage areas and when traveling abroad.

Cost: Included with your calling plan
