What started as a personal decision to find a safe, reliable alternative to my primary number for staying connected, quickly grew into a helpful, effective business resource. In 7 years, I've never had issues using Sideline, and when I've had questions, their support has been responsive. Sideline has come to my rescue countless times, in all kinds of situations, plus they frequently introduce updates, improvements, and new features without compromising how easy and functional it is to use.

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!

Great app to have as a 2nd number on phone. I can keep my business phone no. separate from my personal number. Would be even better if it was also an app on PC like Skype which I hate but have to have for now. Customer service could be improved. Also do not like that I cannot copy a number from a number called it. Needs some user improvements to speed things up.
