I have a sim only EE contract. The phone works in the UK and has latest Android update. I can't see the Wifi Calling option in the phone app settings.
Solved! See the answer below or view the solution in context.

@Komakino Where is the phone from?

Go to phone and dial *#1234# and share the info.
Not all firmware types will have WiFi calling in it. And seeing as you don't have a UK one it may not work on the EE network anyway.

You have a dual sim S7.
Which market did you buy this from can't find that on the Sam Mobile site at all.

As far as I am aware you cannot install BTU firmware on dual sim handsets so you will not be able to use EE VOWIFI service.

Northerner is correct. You can't install BTU firmware on your device.

Oh. That's very disappointing. I got the phone from Hong Kong. Might I ask why dual sim phones aren't supported?

@BrendonH , I'm not so sure dual sims are not sold in Europe because there isn't enough of a market. Carriers don't want unlocked phones to become popular, and they especially don't want dual sim phones to become popular, because they want devices which tie users to their networks. In other European countries where unlocked phones are more widespread you do see cheaper dual sim Android phones, which are used by people requiring two different numbers: maybe one for work and for private calls, or maybe one that has cheaper rates to some numbers, and another with cheaper rates to others.
In summary, I believe phone manufacturers don't sell dual sims here because they don't want to upset the carriers!
I am interested in buying a dual sim, unlocked s7 edge because I want to have both my private number and my work one on the same phone - I hate carrying two phones around. Is there any information anywhere on what dual sim firmwares, if any, are compatible with EE's wifi calling?
On other forums some people said they managed to get the sm-g935FD (which I believe is sold in Singapore and other Asian countries, whereas the OP's verison is from Hong Kong) to work with EE's wifi calling but not with Vodafone's; however, there are no details on this.

It has nothing to do with upsetting the carriers.
If a manufacturer saw a market for it in Europe then they would sell them here.
They are popular in Asia etc because a lot of them travel different countries for business etc.
This doesn't so much in Europe or doesn't matter due to new EU law stating that costs across Europe are much cheaper and capped on data.

I am not convinced. Europe is full of people travelling to and form different countries, or people living in one and working in another (think of all the border areas).
Additionally, you don't need to travel to a different country to find dual sim useful: being able to use both a personal number and a work number on the same phone, without carrying two, can be attractive for most. It's my reason for dual sim; let me tell you, all my colleagues were intrigued and most of them did not even know dual sim phones existed.

@BrendonH , here is an article which reiterates my point about carriers not wanting dual sim phones: http://www.techradar.com/news/exclusive-why-youll-never-see-a-dual-sim-iphone-8-or-samsung-galaxy-s8
