Customer service from Sideline was excellent! They helped me port a business line over and it ported over the date they said it would. Laura from Sideline was very personable and made it a great experience. Very happy that I made the switch to Sideline.


HORRIBLE  PrettyFallon  1 star

I hate writing bad reviews but this is just horrible! I downloaded the app and my free trial started before I picked a number. I have been trying to pick a number and every single number says “oops! This number has already been taken”. 4days now and every single number is taken!!!


Used to be great  ari.jon  2 star

I ported my number over from google voice a couple years ago and was initially happy. A couple things have really started to mess me up lately: 1) when you switch to a team number you can’t text message from the web. This was a cool feature that’s not available to me any longer. 2) if you have a ported number and switch to teams you can’t switch back. So no web messaging available maybe ever? 3) when they recently upgraded to iOS 12 the app failed to function for over half a day, meaning I had no phone at all for this time. This cost me hundreds in lost business, but though I asked for a compensation in subscription time for lost revenue they ignored the request. 4) the app is generally buggy and will often display without a text box to type in, needs to be killed and reloaded with some frequency

Don’t believe everything you read  Regulate The Mind  5 star

My experience was good. After the trial period. I lost connections with my internet along with the phone number. I contacted them via email. They resolved my issue in a timely manner. The issue was resolved before they responded to my email. So far everything is back to normal. It is scary to give out your new number and cannot be contacted, or call out. I think this company work hard on solving issues. Hope this helps you decide.


What’s going on?  jlfigueroa  1 star

Had this app working for 2 years and now without any prior notice if you are living outside the continental USA it stops functioning. Contacted support, and I’m being charged but can’t use it ...



Does not receive text messages. Does not receive verification codes if you use sideline number for apps. VOIP service is terrible, calls do not work when enabled does not matter if you have a great signal or connected to super speed Wi-Fi. E-mailing them is useless and responses to reviews are there to make customers believe they care or have working solutions to what their service promises before subscribing. False promises! Do not believe the hype or paid reviews. Subscription Cancelled.


Money grubbing jerks  Pineapple819  1 star

Suddenly it’s going to be $9.99/mo instead of $2.99/mo? Why? Other than that you’re greedy?


Fee driven service  Kendel72  2 star

When I first started ether sideline it was free. Then the started charging 69$ a year . I don’t know what caused you them to start charging but now there privacy policy has changed/ updated yet again stating that a 8.99 fee is beginning . Not happy at all . I will most likely cancel my subscription based on way to many variances to the service . I used to love this service. So very disappointed.😭
