Anyone tried wifi calling instead of sure signal?

[Speedfriend]

Due to the netowrk connection in my house being so poor, I have being trying to use wifi calling, but it is not a great solution as

The quality is awful with constant sound drop outs and texts don't work.

While it may be my iPhone 6s that is the issue, the fact that I can make wifi calls fine with Skype, Whats App makes me think it is the Vodafone implemntaiton that is the issue. And previously when I was on three, its wifi calls and text app worked fine.

Has anyone else got wifi calling to work or should I spend the £69 to get a Sure Signal (i.e. pay vodafone again just to get the advertised connection signal in my house)? Do they actually work properly? Judging by the comments on here, that seems to be no

Thanks for getting back to us.

I've checked your Vodafone Sure Signal and it seems to be up and running fine, it's showing your last contact with the server was last night at 9.53pm.

Please let us know how you're getting on with it.
