It’s good but basic – Talkatone: WiFi Text & Calls Review

Doesn’t have any fancy features like allowing you to be on hold, it likes to drop then. If you have really important irs type calls with long hold times don’t use this app because you will get frustrated with the frequent drops. Good if your too cheap to have your own service plan, lots of people around you have hotspot and if you live abroad and just need to make occasional U.S calls.
