12 Best Second Phone Number Apps for Android and iPhone

A second phone number app is a dialer provider that gives you a second line. This line works like your first number. It lets you make outbound calls and people can also reach you on this line.

Of course, if your phone has a second sim slot, you may just get another sim and use it. But if you?re using an iPhone for instance, then you might not have that option. In such situation, a second phone number app is your best option.

Also, when you no longer need the second number, you can easily get rid of it. Alternatively, you could also keep it for permanent use. The choice is yours. Interestingly, some apps have free versions or a trial period. It?s a good idea to try out any second phone number app you want to use before purchasing it.

Why Would You Need A Second Phone Number App?

So, why would anyone need a second phone number in the first place? Well, there is a plenty of reasons I can think of and they don?t all have to do with dating sites. Below you will find a few reasons why you might need a second phone number.

To Help Maintain Your Privacy

First on our list is your privacy. This is probably the most important reason why most people get second phone numbers. With a second phone number, you can easily keep your main phone number private. The second phone number app gives you a number you could give everyone. This way, you can keep your private number for family and close friends.

It Gives You More Control Over Your Life

Again, a second number is a way to maintain control over your life. Things can get pretty crazy in a hurry if you have to use your main number all the time. So, for business, online adds or web signups, you can use your second phone number instead. This is a great way to keep your private line for private stuff. By the way, not only second number apps give you more control over your life. You can also use special call recording apps that are very helpful when you need to remember all the details of your business conversations.

It Reduces Stress

Another good reason to keep a second line is to save you the stress of multiple phones. Imagine carrying more than one phone around all the time, it can get pretty stressful real fast. Chuck the extra phone and get a second number app instead. That way you enjoy the convenience of one phone with an extra phone number.
