Vivo – WiFi Calling and VoLTE

I recently learned about these 2 services offered by several carriers, including Vivo, but I was not successful in enabling them because I am not considered a qualified customer.

For those who do not know, here is a quick explanation of each service:

• WiFi Calling or WiFi Voice: a service used to make or receive calls over Wi-Fi in places where phone signal does not exist or has interference.
• VoLTE: a service that uses the 4G network to make calls clearer and more stable.

The carrier's response to a complaint I made through Anatel was:

"We clarify that the WiFi Calling or Vivo Voz WiFi service is being made available to postpaid customers (individuals and companies) to make and/or receive calls via Wi-Fi. The service is temporarily unavailable for prepaid and Controle customers. The VoLTE service is available for prepaid lines, but it is incompatible with the Vivo Easy service."

Since then, I still disagree with their position on WiFi Calling. In places where signal coverage is poor, this service would make consumers' lives much easier.

This is already the second complaint I have written here about the carrier. I admit that to this day I do not know why I still use their services. Everything is very hard to solve, with total disregard for customers. Reclame Aqui has several complaints from me with no response.

And you? What do you think about this? Do you agree with the carrier's position? Comment what you think. I even considered opening a petition so they review this issue.
