Sideline is a versatile second phone line app designed for professionals and entrepreneurs who need a separate business number without the hassle of a second device. With features like call forwarding, text messaging, and voicemail, Sideline helps you maintain a work-life balance while staying connected. Enjoy the flexibility of managing your business communications seamlessly, all from your existing smartphone. Elevate your professional image and streamline your interactions with Sideline.

Features & Highlights

Sideline: 2nd Phone Line App is a game-changer for anyone looking to separate their personal and professional communications. With its robust features, it provides a seamless experience that caters to various user needs. Here are some of the standout features that make Sideline a must-have app:

  • Second Phone Number: Sideline allows you to create a second phone number that works alongside your existing one. This is perfect for freelancers or small business owners who want to keep their work and personal calls separate. Imagine being able to give out a business number without the hassle of carrying two phones!
  • Text Messaging: Not only can you make calls, but you can also send and receive texts from your Sideline number. This feature is invaluable for managing client communications without mixing them with your personal messages. Picture this: you’re at dinner with friends, but you can still respond to a client’s urgent text without any awkwardness.
  • Voicemail Transcription: Sideline offers voicemail transcription, which means you can read your voicemails instead of listening to them. This is especially useful when you’re in a meeting or in a noisy environment. For instance, if you miss a call while at work, you can quickly glance at the transcription and decide if it’s worth calling back immediately.
  • Customizable Features: The app allows you to customize your voicemail greeting and set up auto-replies for texts. This is a great way to maintain professionalism, especially when you’re unavailable. Imagine being able to set an auto-reply that informs clients you’ll get back to them shortly, enhancing your professional image.
  • Call Forwarding: With Sideline, you can forward calls to your main number or another line. This feature is particularly useful when you’re traveling or working remotely. For example, if you’re on vacation but still want to be reachable for important calls, you can easily forward your Sideline number to your personal phone.

    This is an awesome app for anyone who needs a 2nd phone number. I have it for my business so I don't have to give my personal cellphone number out & this allows me to have a completely separate phone number for my business. Sometimes it gets a little glitchy but not that often. Customer Service has always been able to resolve any glitch issues with the app.

    The app works good. My one issue is, the app constantly requests my contact list. However, the reason people want a Sideline number is for business associates or one-time calls. Basically it is for people you don't want to give out your real number to. Family and friends are going to have your real mobile number. So why would I want my contact list on the app? Adding your contacts should be optional, or there should be a completely separate contact list within the app.

    Unreliable business or second line! Absolutely no service on Christmas, up to even now. On the most significant holiday of the year, no service! I lost out on important calls and others who reached out because once again this app failed! And I'm paying an annual fee! Customer service wasn't limited, it was non-existent!! They were aware of same issue last month but no attempt to prevent it again. This, right after I paid another year's annual payment. There's other apps, don't waste your money!

    This PAID app is trash I can recieve but can't connect to my incoming calls. Their tech support has been unable to get the issue resolved. I've been told to unistall & reinstall the app and, Nothing. I've been told been that they reset my pilot number and, Nothing. My advice to all considering this app is "You can find better more productive ways to spend your money". When the app works it works well but when it doesn't its developers don't seem to know what to do to resolve your issue.

    I love having the second line for business, but have issues. First, I can't search messages for words or peoples names (did some searching and see you have it available for IOS but not Android). You need to get it available in Android too! Second, half the time I go to return a call and click the number and say call back. It tells me the number has been disconnected. (I know it's not.) If I try again a few hours later or manually type in the number instead of clicking on it, it works fine.
