[Q] Canadian Koodo Nexus S - Not compatible with UK 3 Sim

Hi,
Recently got a Koodo GTi9020A and have tried to use it in the UK with a 3 Sim.
The phone gets a full 3G signal, data and internet work, however there is a problem with making calls when using the 3G signal.
When the phone is turned on I can make one call to a landline, however if I hang up and dial again there is silence. Calls to other mobiles are scrambled.
I have spoken to Google and have been told that the Canadian software will not work with a UK Sim and the phone will need flashed with UK software.
The phone is therefore 'locked' to the Canadian networks. The lady from Google mentioned that a fully unlocked phone would be more expensive!
Any advice appreciated.
Thanks.

WiFi calling on SM-G930W8 (Canada version) s7 with Cricket cellplan

I have an unlocked SM-G930W8 (Canada version) s7, and I would like to do WiFi calling using Cricket as my carrier. Is that possible?
The Cricket website says:
"Note:*If you did not purchase your phone from Cricket but it is Wi-Fi Calling capable, you can still use your phone but Wi-Fi Calling will not work."
Cricket does not include the s7 in their list of WiFi calling capable phones. I was thinking one possible solution is to flash it with AT&T firmware because AT&T includes Wi-Fi calling on their s7's. Would that work?

Unlocked G930T wanting to use wifi calling on new carrier AT&T

My phone was originally bought for use on tmobile, its been unlocked for a while and ive recently switched to at&t, which doesn't support wifi calling on unlocked samsung phones. I thought maybe flashing the at&t version could fix this but the only post i found on here from tmobile to at&t suggested wifi calling wouldn't work. Is there a solution to this or am I stuck with no wifi calling?

Probably stuck

ATT on T-mobile

I am thinking of purchasing a Samsung Note 20. If a phone is unlocked I assume it would work on T-Mobile. My question is if I purchase an ATT variant, I know the phone would work with a T-mobile sim, but will VOLTE (wireless calling) work if it an ATT branded phone and wether there's an issues with updates.
Thank you

Basically it should work.
According to the following thread, there might be some issues using 5g though:

Experia 5 ii wifi calling support on US Variant.

Hi,
Is wi-fi calling supported on XQ-AS62, US Variant of this phone ? If so, which networks. I am specifically interested if the feature works on Tmobile or a Tmobile MVNO.
I see contradictory information on the forums and hope someone who owns the phone can give a definitive answer.

As mentioned on other thread:
"Nope, I am using T-Mobile and Wi-Fi calling is not supported(no option in settings), even *#*#4636#*#* menu shows Wifi Calling Provisioned toggle disabled and Off (VoLTE Provisioned is disabled and On)"
I did some research and there is no definitive answer to why Wifi Calling doesn't work with T-Mobile but I suspect it has something to do with Certification from T-Mobile, Sony and T-Mobile should work like they did for VoLTE to enable Wifi Calling. (Not sure if rooting and adding some config will change this but out of Box Wifi Calling is not working with T-Mobile)

Thanks for the information. I assumed the North American variant meant it would support all network features of US carriers.
I see Sony Experia phones in the past that did support wi-fi calling on Tmobile, so its surprising they have dropped the support on their flagship phones.
