How about FaceTime, google voice, Skype, Facebook messenger just a few
Add Viber to the list
A group of us from the US visited family and friends in Southeast Asia. We all used free Viber for ALL text messages, photos, video and phone calls using our regular cell phone numbers.
Viber uses your regular cell phone number to make and receive phone calls to other Viber users
It a common way people communicate overseas. They use data only plans in many places overseas or even just WiFi.
Viber uses the same phone numbers in your contact list
Everyone we know uses it overseas including international however we all installed the app on our cell phone and it works the same as a regular cell phone. You can call and text all your contacts using their regular phone numbers.
We do not use a paid version but you might need to let’s say to call a landline. I don’t think a non Viber user can call your regular phone number without using the app to do it so think that is a no go for you regarding business calls that your are concerned about
I do know family members communicate regularly around the world with phone calls using the free app
It works well and my wife prefers it over using our landline
We even set up a group chat to stay in touch with the group to text and send photos and video
An extensive guide on how to make international calls for free. We will guide you through the process of international calling using your smartphone.

Crud! It’s early AM going back to sleep and I see that I already replied to your thread but this does explain Viber better using data only plan for phone calls, texting and sending media free to others. You can even use a cell phone with no paid service as long as you have a WiFi connection.
I realize it may not fit your needs but will help others. Anyone that has their friends and family install the Viber app can communicate for free using their regular phone numbers which is phone calls, text, photos and video
