Best second phone number apps: Everything you need to know

Are you looking for a second number for business? It's really easy to get started with an extra phone number. You don't need two devices, you can simply add a second-line app to your current phone.

But not all second-line iPhone and Android apps are created equal – it's worth doing your research to find the best phone line for work on your smartphone.

These types of apps have plenty of advantages, which is why more and more individuals and businesses are considering using second phone number apps. If you’re a small business, startup, freelancer or sole trader thinking about getting a second number app, here’s everything you need to know about the best phone number apps in the UK.

What is a second number for business?

It's simply a phone number that you can use for all your business calls and texts. Rather than give clients and customers your personal mobile number, you would share your second phone number. Thanks to working from home, the lines between work life and home life are more blurred than ever. A second phone number for business allows you better separate the two, without causing any negative impact on the day-to-day function of your business.

Why do I need a second number app?

If you’re wondering why you should set up a second-line app for your business, the easiest answer is that it will save you time and help you organise your communication. Here are other reasons why your business needs a phone number app.

A second number for work: When you install a second number app, you get a number that you can use exclusively for work-related calls and messages. Your personal calls, messages and contacts won’t get mixed up with your professional communication.

Added privacy: If you use the same number for work and personal calls, you’re risking your privacy every time you share it. But with a second number, you can confidently share it and display it on your website or social media platforms.

Auto-reply to missed calls: You’ll never miss a business call again when you get a second phone number app. Outside office hours or during weekends, you can be with your family and set up auto-reply to missed calls. This is how you can achieve a better work-life balance.

Ease of use: With most phone number apps, you can download and get started in a few minutes. There’s no need to wait around for a provider to activate your number.

No device needed: Perhaps the biggest reason why business owners should consider getting a second-line app is that there’s no need to buy an additional phone. It can work on all your connected devices.

I'm a small business owner: do I actually need a second number app for work?

Absolutely! If anything, you need it more than many others. Why? Because a second phone number used exclusively for business shows that you mean, well, business! It gives your company a more professional look, which will encourage customers to use your services.

Running a small business has never been easy – and it's got even harder in recent years. As a small business owner, you're very unlikely to have a personal assistant or an automated answering system on hand to take care of your daily business calls when you’re otherwise occupied. With a second phone number for business, you get that, plus many other benefits that are super useful.

What should I consider when choosing a second-line app?

Startups, small businesses and freelancers should consider the following factors when choosing a second-line app.

• Access: Your second phone number app should be easy to download and let you start making calls without a lengthy registration process.
• Cost: Second number apps typically have subscriptions. Your provider should have reasonable pricing plans that suit your usage.
• Features: The app should give added features that will optimise your business communication. It should have auto-reply, a professional voicemail, and let you route calls to others.
• Customer support: It should be easy to get in touch with the customer service team – you shouldn’t have to contact them multiple times.

Do I need extra features?

You should go for a phone number app that delivers more than an additional number. If your second phone number app can create lists and further enhance customer interactions, it will save you time and help improve your customer engagement.

Keep in mind that too many features might make an app complex to operate – the number of features is not as important as their usefulness to your business.

Second phone number apps: at a glance

Burner

Burner was initially rolled out as, well, a burner phone. You could use a number and then get it removed from service. But now the service also offers a permanent second phone number. The Burner number app enables you to get a temporary number quickly when you don’t want to share your personal phone number. This is certainly convenient, but if you're looking for a dedicated second number for work, it's likely not the right option.

One of the standout features of Burner is its easy integration with other software such as Evernote and Slack. You can also use SoundCloud to publicly or privately share your voicemails.

• Integration with Slack and Evernote for greater collaboration

• SoundCloud integration for sharing voicemails

• Complex interface
