It was fine until i had to start subscribing.


Great app - second number is handy!  Santhosh2386  5 star

Wonderful calling app. The call connects well and sounds perfect. My wife and I share the phone number for things we handle together, either of us can pick the call. This is very useful since we have our kid in a daycare and either of us could attend the call when something is needed. It gets better with every update.


Sideline 3.0 is clean and elegant.  Alex752  5 star

This app gets better and better with every update! Now I have a second phone number that I can give out to people who I don't want to have my real cell number. The best part is that all calls are connected through my carrier so I don't need wifi. Plus it has unlimited texting. Works perfectly, and the new UI looks great.


No more free version???  xtagenesis  1 star

So, I've been using Sideline for work purposes for a couple of years now. There are often times that I need a specific area code number so I switch regularly. Today I went to get a new number and behold it's telling me I have to pay a monthly service charge now which is a real bummer. This really is a great service especially in my line of work but I can't justify paying a monthly service charge for it. So I’m updating my review today and reading through the “latest” reviews. Most of which are fake reviews with consumers raving about paying $9.99 a month for the service. It’s sad that Sideline now has employees pumping out fake reviews to inflate their product.

Sideline never failed me until they started charging monthly. Wow disappointing


Works well overall as a second line  JJRJoe  4 star

Would be nice to be able to mute text threads like the native iOS messages app.


Work Fine For Texting & Voicemail  Ivana2016  2 star

Terrible for calls. Long delay and echo on ALL calls. Totally unusable for calling.

Had this service on free trial for several months and it was great. Once I essentially purchase my phone number, my clients can’t stop complaining about how they hear everything their saying in an echo. So then I have to call them back from my other phone line. How annoying is that? Called Sideline and they said I should try deleting the app and re-installing. Great, then I can lose a year worth of important text messages from clients.
