You’ll agree that carrying two smartphones, one for business calls and one for personal use, is not convenient at all. Luckily, the modern world has taken everything and turned it into an app. Now you don’t even need to buy a second SIM card to make calls to your colleagues. What you need is a special second phone number app that gives you a second line for local and international calls. In this article, we’ll check out the best second phone number apps for Android and iPhone, and compare their main features and pricing. 

Why You Need a Second Phone Number App? 

There several reasons why people use second phone number apps. First of all, the second phone line lets you manage your personal and business calls and use different phone numbers for family and work. This is very helpful when you don’t want to share your private number with business partners and colleagues or receive business calls in your free time. What’s more, the second mobile number is helpful when you’re asked to sign up for a service and to verify your identity. 

Younger people will also find second phone number apps useful, especially when it comes to dating. Many apps provide you a burner number that is temporal so you can be sure that your real number won’t get into the wrong hands. What’s more, using a second phone line may save you a lot of money when you travel abroad since you can text and talk overseas without ridiculous charges. Finally, second phone number apps can help you prepare for unforeseen events and provide you with a backup phone number.
