S20 FE 5G Wifi Calling Weirdness

Hello. New member so go easy on me! 

Need wifi calling because Signal on any network here is just ***** (and yes, have ordered a bunch of PAYG sims and they all have issues - location, house etc). 

So - I've just received an S20 FE 5G (replacement for a Note 4!), came from Vodafone but has been factory resetted because of Corporate security requirements. It 'appears' to be unlocked because I've put a Vodafone, Sky & Three sim in and all work fine and register and i can receive calls. 

So, onto issue 1 (now fixed) - Vodafone (Business) - Initially Wifi calling wasnt present at all - not even a button on the phone. After some discussions with Vodafone & Samsung (Samsung said its not the phone, its a Network Operator issue), did a lot of restarting and sim updates, eventually got it to work... Vodafone had to 'do something' = they wont say what. 
So, Sim 2 (Vodafone) now works perfectly with Wifi Calling. 

So, onto issue 2. Sky. I have Sky Mobile as personal number and picked this phone as it has dual sim etc. 
Tried to get it working using Wifi calling - wont activate. Icon there, says its active for Sim 1 (Voda is Sim 2). So, i thought, "phone sky" get them to turn it on, blah blah etc.

Lots of conversations later and me blaming Sky, turns out its not Sky... 

If i put the Sim in another Samsung (A12), Wifi calling activates immediatly. 

 

So back to the drawing board.

If i put a THREE Sim in, either on its own, or with the Vodafone sim card in Slot 2 - wifi calling works! 

Its as if it doesnt like the Sky sim! 

And note, to test wifi calling i've been turning on flight mode, then activating wifi. 

So, to summarise...:

  • Put Voda Sim in alone - Wifi calling works
  • Put Three Sim in alone - Wifi calling works
  • Put Voda & Three Sim in together - Wifi calling works (on both)
  • Put Sky Sim in alone - Wifi calling doesnt work
  • Put Sky Sim in with Voda Sim - Wifi calling doesnt work on Sky, only on Voda
  • Put Sky Sim in with Three SIm - Wifi calling doesnt work on Sky, only on Three

If i do the above on the A12 though > All hunky dory and Wifi calling works on all three networks. 

Any ideas ladies & gents because im seriously getting frustrated now. 

Phone is all up to date etc. 

Cheers!
