Yes bear in mind I can use BT anytime calls to phone out however I need to receive calls on my mobile - I have WiFi but rarely get a 2G signal in most parts of the house let alone 4G. I can’t just stay in some uncomfortable part of the house in case I get a call. Hence the change of mobile provider.
Unfortunalty Wi-fi calling is only available on iPhones 5s and above. And VoLTE (or 4G calling as BT call it) from an iPhone 6.
As Apple have stopped supporting the new updates for iOS on iPhone 5, if you are looking to change handsets at any point look at ones that support Wi-fi calling.
Thanks for your reply, I will be looking to move back to O2 when my contract ends as the lack of signal is apauling. Having checked online how service is supposed to be in my area before signing up...i basically don't have a mobile phone when at home.
Unfortunately the coverage maps are a guide on all networks, I’ve got an EE mast almost on my door step but still no signal indoors. If you know o2 will work for your then stay with them.
Why don’t you contact BT and see if you can get out of your contract early.
BT has now migrated my SIM to 4G calling now so its available now. check your settings and you may be surprised. It has solved alot of my problems. However, my BT router doesnt seem to handle the wireless now and staretd to affect the BT sport and resets everynow and again on its own.
you were correct tho! The migration is for both Wi-fi and 4G calling.
