Add a second phone line using your existing broadband and home phone. Start making unlimited¹ calls from just £3.99 per month with a new second phone line.

It's increasingly common for households to add a second telephone line. An additional phone line works in the same way as a regular phone line but with a separate phone number. An additional phone line can make life so much easier in many ways, for all the family, as well as save money.
Read some Vonage stories from our customers, many of whom decided to add an extra phone line.
At the moment, your phone is probably plugged into a phone line socket in your wall. If you use Vonage as a second telephone line (or several additional telephone lines), you would simply unplug your phone from that socket and plug it into a Vonage adapter. This adapter would in turn plug into your broadband modem or router. Find out exactly how Vonage works here.
Another wonderful benefit of having Vonage as a second phone line is that it's entirely portable. Typically, a phone line is directly linked to your main country of residence and more specifically to a particular house. However Vonage is a portable second phone line, meaning your phone line no longer ties you down to any one house or country.
If you go on holiday or abroad for work, you can simply take the second phone line with you. As long as you've got access to broadband, your Vonage adapter and a normal phone handset, you'll be able to make unlimited¹ landline calls on this additional phone line. People can call you on this line as regardless of where you are in the world.
If you have a cable broadband and phone line service (Virgin Media, for example), you have a choice to make. So you can cancel your cable phone line service without affecting your cable broadband service, and use Vonage as your main phone line. This flexibility is down to the fact that your cable broadband and telephone lines are in fact separate. Or you can choose to simply add Vonage as a second telephone line.
If you have ADSL broadband, you don't have the option of cancelling your phone line service and keeping your broadband as they are tied together. You can though still save money by using Vonage as your second phone line and reduce your dependency of your main phone line.
When you add a second phone line from Vonage, you select a call plan that allows you to make unlimited¹ calls to landlines. If you regularly call internationally, additional phone lines can help cut costs because we also offer a range of low-cost and unlimited¹ international call plans.
So no matter what your current phone line and broadband set-up, once you start using Vonage as your second telephone line to make unlimited¹ landline calls, you'll quickly notice a difference in your overall phone bill.
