What is the point of internet calling?

I have a Samsung A13 with Tracfone service. Two people that I know use internet calling andtexting while at home so that their time and texts are not reduced. They have different phones but my time with this phone continues to be reduced. (02:24:37 PM) Customer Service: Thanks for your message, please wait a moment while our experts attend to you.

Nice to meet you, *****!
Wi-Fi calling is beneficial for numerous reasons. Most notably, it allows you to communicate from the most remote locations, as long as an internet connection is available. That means you can make voice calls and send messages whether you're indoors, outdoors, or even underground.

I live in an area with abundant cell towers and rarely am anywhere that I cannot use cellular.

Anton Hrytsaienko

Ok
Do you have any additional questions I can help you with?

Customer Replay

Yes. Did you read the question about the charges for internet calling. That is my question since I am usually calling from home and am on a fixed income.

Anton Hrytsaienko

Not all countries and not all operators offer the ability to make Wi-fi calls.
So, it's not beneficial in that area.

Customer Replay

That doesn't answer my question.

Anton Hrytsaienko

Ok, *****. Can you please rephrase your question? What do you mean exactly by "reduced text messages and calls"?

Customer Replay

I am being charged to make calls and send texts.

Anton Hrytsaienko

Ok, and do you have connected Wi-Fi calling right now, or do you want to know if there will be the same when you connect to it?
Because, in most cases, Wi-Fi calling does not incur any additional costs. Most cellphone providers will treat Wi-Fi calls the same as any other call and deduct those minutes from your cellphone plan's allotment.

Yes I am sitting in front of the modem.
