Next Monday, March 10, marks the 138th anniversary of the first phone call. Even though many of us primarily (or exclusively) use cell phones, there are still many reasons why using a home phone is beneficial. According to Vonage, consumers greatly benefit from both a home phone and mobile phone because they can extend their home calling rates to mobile phones through the Vonage Extensions program -- which is free to all Vonage customers. Extensions builds upon Vonage’s history of providing exceptional value to customers through calling plans that allow them to call friends and family anytime, anywhere from any phone. Vonage has also made a free mobile Extensions app for iPhone and Android available for download, enabling you to one-touch dial from your existing mobile contact list. Through the Extensions app, Vonage customers can make high-quality calls via the Vonage network anywhere Wi-Fi is available, including areas with poor cellular coverage or when traveling overseas to avoid hefty cellular roaming fees. Calls can also be made over 3G/4G networks (data rates may apply).
