Can someone use phone's internet to make wifi calls?

This is probably a dumb question. T-mobile offers free international wifi calling and also free international data. Maybe the data is too slow in many countries. Is there an app or a way to run the phone's wifi and then use the wifi calling feature? If one has wifi then no point but if one doesn't it would be cool to do.

The cellular voice part of the phone needs network support for the wifi to work seamlessly. However there are many apps like google chat that allow phone calls over wifi. These app services are separate from your cellular and have a different phone number involved. International calling may require you subscribe to the service too.

Tmobile says the wifi calling will work free automatically, well at least that's what I read. I suppose I would need to call them and ask to make sure since it was a 3rd party article reporting on their wifi calling and now good it was. Probably no way to turn on wifi hotspot while at the same time use the wifi calling from the wifi hotspot.

WiFi calling to cellular handoff

I'm finding that when I'm on a WiFi call and leave the house, the phone dosent switch to cellular. The phone drops the call and I have to call the person back. Is there any setting to enable smooth handoffs or is this an inherent issue with WiFi calling?

Have you tried going into developer options, and ticking aggressive WiFi to cellular handoff?

I'll give that a try. Thanks

If you are on T-Mobile, I don't think it will do a WiFi-Cellular hand off, will it? I thought T-Mobile still uses IMS technology.
The older wifi calling tech, UMA, does handoffs nicely. The older Blackberrys and Nokias have it.

Enabled the aggressive wfi to cellular handoff and that seems to work now. Thanks.

Verizon WiFi Calling

So, Verizon says that they can't provide WiFi calling, however, the new radio supports it.
Any way to force the network to provision our Nexus 6 phones for WiFi calling?

I also couldn't figure it out.

What cell companies have WiFi calling that works with the Moto Z3 play.

I have a house that gets no cell signal (from any provider, I think), and I just found out ATT hasnt enabled wifi calling on the Z3 play (I think). The house has broadband internet, just no cell signal.
Has anyone successfully used WiFi calling, and with what provider?
Also, are there any other options besides expensive microcell tower boxes? ( Microcells seem like a bad option because the family uses several different cell companies)
Thanks in advance.

Republic uses wifi calling through their app. I use at work where i have no wifi signal.

T-Mobile WiFi calling works.

Yes t-mo is the way to go.

Can anyone confirm wifi-calling is working on Verizon?

I dont find a way with Verizon

T-MOBILE has WI-fi calling.

Sprint does for sure. their Wi-Fi calling takes it a step further, in that when transitioning or leaving Wi-Fi, while on a call, it is a seamless transition. (ie. The call does not drop connection, because it is always connected )

wifi calling works without carrier firmware

I bought a SM-N960U1 unbranded US unlocked model, and I immediately updated it to Android 9. THEN I inserted my T-Mobile sim, and I have wifi calling. I did all of this a few weeks ago, and I never really questioned it all until today.
I'm posting this now because I read that people cannot get wifi calling to work on their unbranded model unless they flash carrier firmware.
And this is what I've found. When I make a call while connected to wifi, I see the little wifi symbol on my phone symbol, as if the call is a wifi call. I have a toggle for wifi calling, which works! If I toggle wifi calling off and make the call again, no wifi symbol on the phone symbol. When I look in settings > connections, I do NOT have items to set wifi calling and VoLTE. However, I can search settings for wifi calling and I will find the Samsung 'Wi-Fi Calling' app (com.sec.unifiedwfc 6.0.33.47) RUNNING!
So, it seems I have wifi calling working on T-Mobile, with just the Samsung stock firmware and not the carrier firmware. Which is great! No carrier bloat.
I just tested my wifi calling by starting a wifi call and then walking out of wifi range, and it definitely works! At the edge of wifi range, the call broke up, handed over to the cell tower, and became noticeably less clear. I'm stoked to have wifi calling without carrier bloat.
I might investigate further if there are some settings I can toggle over adb (wifi preferred, etc)

It depends on the carrier. T-Mobile does support all of its services, including WiFi calling, on the N960U1. Some other carriers do not. Always check with your carrier before buying an unbranded phone.

I also just discovered that toggle button text is CLICKABLE, and I can access Wi-Fi Calling SETTINGS when I tap on the wifi calling toggle's text, which gives me the option to turn on/off wifi calling, wifi/cell preferred.
So I have Wi-Fi Callng, can change settings, all in the stock non-branded firmware of the SM-N960U1.
AWESOME!
