Hi Syaoran,
The old phone didn't have any issues. I suspect more and more Android is the root cause of these never before seen problems. Which carrier is more 'sympathetic' to 'grey' devices (do you mean unlocked?)?
I don't see how Android would be the issue. Sympathetic is not a word I would use when it comes to a business. Consumer friendly policies would be my choice of words. Outside of Telus/Koodo, and in some cases, Bell/Virgin. Devices that are not permitted to work on those networks usually work perfectly on Videotron/Freedom and Rogers/Fido/Chart. I have never used the device you purchased but OnePlus or my US purchased s23 Ultra are good examples of devices that work on every network in Canada but Telus/Koodo restricts those devices from VoLTE, WiFi Calling, and Roaming in the US.
All Canadian carrier devices must be sold as SIM Unlocked as mandated by the CRTC. Devices not sold by Canadian Carriers, meaning devices from the US and other countries that are not iPhone's, like European and Asian devices. Blu is a good example. Great devices. Very compatible with Canadian and US networks and carriers but still won't work for VoLTE and WiFi Calling and not allowed to roam in the US on a couple of Canadian carriers. Not because they won't because they are not allowed.
