Good but needs work

The app works good but could be better. There are a lot of bugs that could still be fixed. First I’ll start with calls are very delayed. By the time the call gets forwarded it’s about 2 rings before it’s a missed call. 2nd this one bugs me the most. Recent calls, texts or voicemails disappear or will not show up on recent call screen. I use this line for my business and When I’m working I don’t hear my phone so when I check it my phone will say I’ve had 2 missed calls and a voicemail but when I go into the app they are not there. Now if I open it thru my notifications screen on my iPhone it will sometimes take me there. Next when I click on some of my customers text threads a different customer thread will show and I have to close the app and reopen it for it to work right again. As of this very moment my app shows 10 notifications but I can NOT view them. They are missed calls, voicemails or texts that I cannot see. I also notice that a lot of times I have missed calls or voicemails and my phone never even rang. And my final issue is voicemails should ALL go into a separate folder. It’s shouldn’t be in the call thread because after a call or text from that number it makes it hard to find your voicemails so that is something the developers should change. Other then these issues the app and idea is great. Hopefully they get these bugs fixed soon and this will become a very good app.

Version 4.20.0 does not work at all!

After reinstalling twice I still continue to get the same error message, “Error, no cellular connection. Please make sure you are in an area with coverage.” I have checked. Cellular works for all other apps, my actual cellular connection is great. Cellular is turned on for the SmartLine app in settings. Wifi has been tinted on and off, off and on, I’ve tried it each and every single possible way I could think of and still no outgoing calls work. Incoming calls work though, as does text messaging. But outgoing is a bust.

This app is useless as it now stands, and I’ve just gone past my 7 day free trial period so I also had to pay GoDaddy $10 for an app that doesn’t work. I tried calling for support to no avail. Customer rep was nice but just as clueless as I now am, and when our call got disconnected after troubleshooting for 20 minutes, and then being put on hold while my rep went to try and find a resolution, I received no call back. So app gets 1 Star and support gets 1 Star.

I pray that the reason my app is not working is that I’m simply doing something wrong but after troubleshooting by myself and with tech support for a while, I fear that this app is a buggy waste of money. Maybe 4.20.1 will fix it? Maybe 4.21.0? Can I wait that long to not be able to make calls though? Probably not.

We're sorry to hear you've had issues with both the app and with customer support to troubleshoot the issue. We'd like to opportunity to investigate what's going on with your outgoing calls. Are you calling the same number every time?
Please email us at SmartLineiOS@godaddy.com with your SmartLine number. If you could include a screenshot of the error, that would help us get started right away.

Handy device but needs improvement

I have an iPhone 7 and the SmartLine ap worked great up to a point. All of a sudden it would show I have a message or call by marking the ap icon with a number. After I viewed the messages the number would not go away. I would have to delete all my calls to get the number off the ap icon. I uninstalled the ap restarted my phone installed the ap and it made no difference. Then it wouldn’t show any of my incoming calls. It would spin and spin as if it was downloading them. Finally I let it spin and about 20 minutes later it showed my calls and all my issues have gone away thus far. When it works I like it. My only other “wish” for this app would be if you could have multiple voice mail messages. Like one for when your busy and can’t answer the phone and one for when your business is closed, you could turn them on and off as your work schedule reflected.
