Vonage works pretty. darn good, especially for Wi-Fi. calling with your cell phone. and the spam system seems to work really nice too! our problem, is that it seems a little bit flaky when the internet is a little bit flaky. it hangs up on us and sometimes it gets messed up and we have to restart Vonage or restart our cell phones. then it works great again!

This app used to work with little to no glitches, but now whenever I receive a call it keeps on ringing and the caller info does NOT show up on my galaxy s25 ultra. Even if I close all apps it keeps ringing, and then after about 50 seconds it finally gives me the option to accept or reject the call. Also problems when trying to make calls. It's a terrible experience at the moment. Please fix the bugs and I'll give you 5 stars. I have uninstalled and reinstalled 4 times, still the same problems.

Trying to access voicemails within this app and it just says "an error occurred while accessing Voicemail. Try again". Still doesn't work. In response to dev. response, app doesn't have a 'storage' option. All perms allowed. Also, immediately after I switched to Vonage, I was inunindated with unsolicited spam and illegal robo calls. I have been on the National Do Not Call Registry since 2003 & rarely ever received illegal calls. Now it's several times a day! Did my info get sold by Vonage? Hmmm.

Thank you for the feedback, and we’re sorry for the inconvenience this might have caused. Please try enabling the app storage setting within Android: Go to Settings, then Applications, then (App manager, if applicable), then select Extensions app, then Permissions, and tap to enable the Storage option.
