Been a customer since 2017. Used it primarily for a business line. Last week it logged me out and said it didn't recognize me. I've tried for several days to contact support. Keeps saying someone will get back with me and no one has. Made multiple attempts to get back in and multiple attempts to contact support to no avail. For the last month prior the service was disrupted due to "the election" and incoming and outgoing messages and calls didn't go through. Just unsubscribed.

I have been through a lot of phone apps. Haven't found one that has ever worked like Sideline. It's a very very good app. Sideline let's you have a 2nd phone number. That you can use for business or private. You can pick any area code you like. Good call quality. I give Sideline 5 Starz.

This app started off great years ago and was free. Then it went to $10/month and the service went to hell. Lately I'm lucky if I can have a minute of conversation before it starts to drop calls or reception goes in and out. It only seems to happen when I use the app. Would not recommend.
