Using WiFi for mobile calls

[#1]

Ok, I'm a luddite but my new mobile had the option to use wi-fi when making a call, from my mobile.
Am I okay to do this?

BTW I have broadband and line only, no landline calls package.

@Stranger Perfectly OK - if your phone is connected to a Wi-fi network it should default to that anyway - 3/4/5G is only used when you aren't.

@Stranger 

To clarify what  @jab1  says I believe that it depends on your mobile provider and according to this Plusnet mobile does not support WiFi calling, see. https://www.simsherpa.com/networks/plusnet-mobile/review-and-guide?accept-cookies

It only uses your WiFi if its a better connection than your normal phone signals.
According to Google
EE, Vodafone, O2 and Three each offer Wi-Fi Calling in some form, as do some MVNOs (Mobile Virtual Network Operators), but some offer more options or make it available to more phones than others.

Hello

I have had WiFi Calling with EE for nearly 5 years and basically it has changed my home from a no go zone for mobiles to one where not having a signal is not a problem.

My broadband is provided by Plusnet.

Some time ago I signed up for an EE deal at Carphone Warehouse which included a Samsung S6.

I had a play with the phone back at home and discovered WiFi calling which I couldn't configure.

I went back to Carphone Warehouse and they explained that the phone had Carphone Warehouse firmware.

In order to use WiFi calling the phone had to have EE firmware.

Or plain old Samsung firmware?

I'm not an expert on such matters, but perhaps you can re-flash the firmware?

(My SIM free S7 can do WiFi calling)

That is interesting. I thought they would just be stock. Obviously badly designed software.
