3.9 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:
As a freelance graphic designer, I often find myself juggling multiple clients and projects. Sideline has become an essential tool in my daily routine. For instance, I use my Sideline number to communicate with clients, ensuring that my personal number remains private. This separation has not only helped me maintain professionalism but also allowed me to manage my time better. When I’m working on a project, I can easily switch off notifications for my Sideline number, allowing me to focus without distractions. Additionally, during networking events, I confidently share my Sideline number, knowing that I can control who has access to my personal information.
The user interface of Sideline is intuitive and user-friendly. Upon downloading the app, I was greeted with a clean layout that made navigation a breeze. Setting up my second phone number took just a few minutes, and I appreciated the step-by-step guidance provided. The feature workflow is smooth; making calls and sending texts feels just like using my regular phone. Performance-wise, I’ve experienced minimal lag, and the call quality has been consistently clear. Overall, my experience with Sideline has been overwhelmingly positive. It has simplified my communication process, allowing me to focus on my work without the constant worry of mixing personal and professional calls.
Sideline offers a competitive pricing structure that is well worth the investment. The app provides a free trial period, allowing users to explore its features before committing. After the trial, the subscription fee is quite reasonable, especially considering the value it brings to managing communications. For freelancers and small business owners, the cost of Sideline is a small price to pay for the convenience and professionalism it offers.
Sideline is regularly updated, which is a significant plus for users like me who rely on its features. The developers seem committed to improving the app based on user feedback, and I’ve noticed enhancements in performance and new features over time. Customer support is also commendable; I had a minor issue with my account, and the support team responded promptly and resolved my concern efficiently. This level of support gives me confidence in the app’s reliability.
As an American user, security and privacy are paramount when it comes to communication apps. Sideline is available on both the App Store and Google Play, which adds a layer of credibility. During the registration process, I was required to provide basic personal information, but I appreciated that the app does not ask for excessive data, which can often be a red flag. Sideline has a clear privacy policy that outlines how they handle user data, ensuring that my information remains secure.
Moreover, I have not encountered any intrusive ads or tracking behavior while using the app, which is a significant relief. The absence of ads enhances the user experience, allowing me to focus solely on my communications without distractions. Overall, Sideline prioritizes user privacy, making it a trustworthy choice for anyone looking to manage their calls and texts securely.





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.
