Companion App

I needed something to call my Dad in The UK instead of having the local carriers cause me to grab my ankles from the excessive charges they normally impart.
This App has allowed me on a daily basis over the last 3-4yrs connect back to my digital phone at home and speak with my Dad until his Passing this New Year Day 2017.
This App has been a blessing and provided me the communication and comfort of speaking to him over the last couple of years daily.
Thanks guys... you did great with this!!!

I use this as my home phone service and I can take it anywhere with me. It is very convenient and great service. Highly recommend by me! 😃👍🏼

It is a good app for voice over IP and for long distance calling. The menu options on screen are user friendly and easy to use, it would be good if they include text messaging
For return callers.
