I have a 6 week old unlocked iPhone 6s Plus bought outright from my local Apple store (IOS is the latest version).
I have recently moved to Vodafone, on a 12 month contract.
This might be relevant to my tale of woe: for the 2-3 weeks of owning the phone, I was with EE on a pre-paid monthly deal. I moved my EE number over to Vodafone, immediately after signing the Vodafone contract. So I had a "temporary" number from Vodafone for a day or so while the PAC code was being processed.
Anyhow, my problem is getting WiFi Calling to work. I have spent HOURS on the phone with Vodafone support and they don't seem to be able to help. When I go into Settings->Phone->Wi-Fi Calling the slider switch is to the left (disabled). If I try to enable it a popup appears warning me about my location being shared (which I assume is standard), then I press Enable. This is where it all goes wrong: I get a message saying "To allow Wi-Fi calling on thie account, contact vodafone UK". Which... I've done, 4 times now in total.
I suspect it's something to do with my number being ported from EE. Vodafone support say that they can see it's enabled on my account, have asked me to check I message is enabled (it was), that the CTN is my number (it was). If anyone has got any ideas, or has come across this before, of just has a suggestion of somethign to try...I would be very appreciative.
Otherwise, it'll be yet another 20 -40 minutes on the phone repeating myself over again.
