Ratings and reviews

I have been using Sideline as a biz mobile number for 3-4 years. I must say, I am very pleased with the service overall. It has been reliable and easy to use. There are some things that should be addressed: 1. The app REALLY needs a Search function. I cannot look up texts or calls without scrolling through and opening every conversation. This is inefficient. 2. If a text or call is received through Sideline while on a standard network call, it disables the speaker function. Otherwise Great!

No calls EVER seem to come through, regardless of being on wifi or off wifi, it just shows Missed Call. It would also be nice to have export function to be able to back up texts to a .txt file with a click. Video quality is not up to standards so don't bother, use your regular phone instead. It's really okay to use as a second text number. I only seem to be able to make outgoing calls, not receive them. I would love to see improvements made @the price you're charging.

Going on my 3rd year with Sideline. I like being able to give out a number that's not my "real" number, and having seperate text and call sounds. I've never had a problem with call clarity, yes it takes an extra second or so to connect, but that's not a big issue for me. Blocking numbers is easy, but if I accidently block one, the process to unblock is too complicated. I have had issues in the past where my REAL phone number was showing up instead of my Sideline number. Overall I'm pleased.
