Thanks for your responses. I've cancelled my contract with BT - after 4 days - and gone back to EE. There's no point having a phone contract if you can't make or receive calls from home. How extraordinary that BT haven't got onto Wifi calls yet. And, I also found that there was no-one to talk to at weekends, because they only work weekly office hours. Also, it wasn't possible to cance the contract and order a PAC code online... At least I couldn't see how.
Correct me if I am mistaken but turning your data off will only stop you using the cellular network for actual data e.g. internet access, which is usually charged separately to cany calls. Even with data turned off you will still be able to make and receive normal telephone calls anywhere there is a cellular signal.
As far as I am aware and the whole pupose of this thread is that BT does not offer Wifi calling at present unlike its new subsidiary EE whose network BT Mobile uses. Those posting on this thread have been hoping to persuade BT to catch up with its subsidiary.
Unless something has happened of which I am unaware your calls are not being routed via Wifi. If I am wrong that would be good news!
Any updates on BT and wifi calling?
I'm thinking of joining BT because Vodafone although supporting wifi calling do not support the iPhone 6 which is supported on EE and as I want a sim only deal it looks like i won't be joining BT.
PS I have 4 phones on my contract so it's their loss times 4.
The Signal Assist box (http://btsupport.custhelp.com/app/answers/detail/a_id/57038/c/7707) allows mobile connections deep in the Scottish Highlands. I have a personal account with BT, use BT Mobile and BT Broadband with HHB5 - and it works well - so far...
Before switching from EE to BT mobile I did ask if wifi calling would be available. I was told that everything hat EE offer would be offered BT.
I switched hoping ping this would happen but BT seem not to care. Inadequate mobile signal in north Norfolk and unwilling to offer wifi calling to overcome this.
when my contract ends I shall switch back.
