Can't make calls

[Stevieag]

I have recently stopped being able to make phone calls.

I could and now can't, I'm on an unlimited contract.

I did recently renew my contract if that is part of the issue? Not really what I expected.

Network working fine in all other ways, data good, can receive calls and and can call voicemail.

Hello Jonathan, 

The Three coverage checker states "We’ll be switching off a 3G mast here on 30 September 2024" therefore my problem shouldn't coincide with 3G switchover as it hasn't happened yet.  

My phones (I've tried multiple) are Motorola e.g. G7 Power, G6+ and these prefer CDMA. From what I see, Three have CDMA turned off for most of the day, however it occasionally comes back and then my phones work. SMS txts continue to work 100% of the time, it's only making/receiving calls that are broken. I spoke to multiple departments in Three (also via Twitter) and they all say I need VoLTE enabled (which isn't supported by my phones). When I switch to a phone that supports VoLTE everything works fine. My problem is that I can't afford a new phone right now so I've switched to PAYG on EE and my phones now work again. 

Regards

Dave
