2ndLine is a tool for setting up two phone numbers for Android devices that lets you give your friends or family access to a second phone number that they can use with all the benefits that this entails.The way 2ndLine works is simple. After signing up with your information, you get two free virtual numbers to give to the people you want to add to your contacts list. You can also add any phone number you have access to (either via work or your personal life). Not only will the other users be able to call you using the virtual number, but you can also make calls using it from any device with Internet access, including tablets and computers.
With 2ndLine, you can call anywhere in the world from your smartphone or tablet at a very low cost. Plus, you don't need to have an Internet connection when making calls because this service works perfectly even when you are offline.
