All of the features worked fine for years until recently. When calls are made through the app, many times my private line is displayed to the individual instead of my smartline number. Customer service instructed me to logout and lo back in. No success, no one can figure out why! It defeats the purpose of having a second line. It is no longer reliable. I will be looking for an alternative.

Texting has never worked. I can send and receive calls but texts do not go out or come in. It has been seven days since my number was set up and still texting doesn't work. The line I ported in was a personal cellphone line. I've called customer service and they said it can take a few days for texting to work. I don't understand. If calls work, so should texts. I'm running the most recent version of the app. I've confirmed everything is set up correctly on my end.

I've been using Smartline for about 4 years now. It's a great way to get your business calls on your cell phone and keep the numbers separate. You can set office hours when your phone rings or goes straight to the greeting. You can also send and receive text messages with media, and it all gets saved on the app, so if you switch phones in the future, you don't lose anything. When you call customers back, your smartline number shows, not your cell. Yes, use Smartline!
