Ratings and Reviews
Thanks for a great app with great customer service! Super glad I joined during your early stages and saw it grow to what it is now...would love to see an updated ability to have multiple "main lines" under one login account vs being limited to one main line and team extensions, i currently maintain 3 phone lines: 1. My main carrier line 2. my SideLine and 3. a second biz line via the "Digits" app by T-Mobile which isnt as good of an app as SideLine is...Wish I can just use SideLine only no matter how many lines I'm paying for. Also, would love to see some features available from the SuperPhone app like the automated "follow-up messages" to keep in touch with contacts that I havent spoken to in a while to build strong relationships, having that incorporated into SideLine's functionality for better business networking would be a game changer...meanwhile, I'm very happy with my SideLine!

This App Has the Best Features
I had this app before it was paid. Loved the features that most apps don’t have, so it operates just like a business line, plus you can choice a special ring tone, change your voice mail greeting, often & more. My issue became serious a few days ago when my new clients were not reaching me because my phone rang once & for them the same BUT it cut them off without access to voice mail. This have cost me great embarrassment and PLUS when I contacted customer service and followed the normal steps. Reinstall the app each time it got worst. I permanently deleted this app & cancelled my subscription and went to Burner app of which is a down grade because I can not access the voice mail, no special ring feature, but I’m grateful to have a working app. I’m disappointed because I still believe sideline is one of the best low cost apps with multi-features I like & appreciated. I guest I will have to upgrade to Grasshopper because I must have a custom voicemail & Burner already has a glitch which prevents me from accessing voice mail. Sideline thanks for years of great service. But when my customer are compromised, that’s just unacceptable. Perhaps this is just what happens in the app world. It’s challenging because all my business cards & social media has the number. Cheers to fixing your challenges as well!

Stuck with it
I gave 2 stars because I actually use it. But only because I have to. A few years ago I signed up when it was still free. Things were fine for a little while and then had to pay to keep it. Not long after that I started having the issues. But I paid and the number is on my business card. So I’m stuck. I’ve talked with multiple customer service reps regarding the issues. I’ve un-installed and re-installed it which caused me to lose 2 years of worth of data. But the problem stays the same. When I open the app, I have to wait at least 5 minutes (yes I have timed it) for it to un-freeze so I can use it. If I get annoyed and close it out to the re-open it, it’ll short out and close out on me anywhere from 5-20 times before it’ll finally pull up and then I wait another 5 minutes minimum for it to unfreeze. The only way to have it instantly work is by doing a soft reset on my phone. Then that first time of opening it usually goes faster until I close out of it, because once I close out of it and then re -open I’m starting over. I used to think it was just sideline but recently I downloaded a couple others and they do it too. Not anywhere near as bad but they do. But my cards have this number so I’m stuck. Unless anyone can recommend something. But I waste a TON of time waiting to be able to use it.
