Question US variant S23 Ultra in Canada

[nazmul arefeen]

I live in Canada and bought a US variant s23 Ultra. Two things I have noticed,
1. Wifi calling can be configured in my provider end (Virgin), and when it ask to complete the setup by turning on wifi calling it does not work.
2. Samsung pay is not working.

Has anyone faced any sort of issues after flashing SM-S918W firmware in SM918U1?
Any cons??
Also, my apps will be wiped or no? I have already seen that I can keep data intact while flashing with Oidin.

Wi-Fi calling won’t work on the U1 (neither with VoLTE) in Canada except on Rogers. Bell and Telus whitelist W model IMEI numbers. Even if you flash the W firmware it won’t work.

If this is the case. Was this a recent change? VoLTE used to work fine as well as 5G using my old OnePlus 8T+ 5G. It honestly wouldn't surprise me but if this is actually happening. I hope everyone files a complaint with the CRTC over their anti-competitive behavior. I won't be able to try mine out until i get back to Toronto after Easter but I will be reaching out to their Executive Team directly if this is the case and consider returning my 6 lines to Rogers.

It was a change sometime last year. CRTC wouldn't do anything because they said it's their network and they can choose what devices they allow to use. CRTC is a joke

It used to be that way about SIM locking devices too. Sometimes things can change for the better. Especially if enough people complain about the same issue.

I tried submitting a CCTS claim but they sent me back the requirements and there is a specific section about devices on their network and how that's exempt. The only way might be writing your MP to voice your complaint. I agree if enough people complain maybe they will do something but I won't hold my breath. In my case I switched carriers to Rogers since I didn't want to give up my U1 device but I know not everyone is in that position.

I need a device compatible with mt T-Mobile SIM and Telus. US devices are much more compatible globally in my opinion and T-Mobile's roaming rates make Canadian carrier rates look like a joke in comparison.

100%.

telus/kodoo wifi calling did not work for me and the phone was from Telus!
Had to switch to Rogers.

I do remember that my previous phone (online bought) was not supported by my carrier for Vowifi, and I found on the carrier forum how to push it with ADB. It worked, can't remember exactly the steps it's been a while

You cannot use a US S23 Ultra with a Canadian SIM card, but you can use International Data Roaming with a supported US carrier.
(This is a MAJOR change for 2023 and beyond. Samsung is putting the final nail in the coffin to end foreign SIM card support on US Galaxy devices, even after a network unlock.)

I did similar with the OnePlus 8T+ 5G. Using QPST, you change the carrier profile for the SIM. This also worked on my Xiaomi Mi MIX 3.

Samsung doesn't care. As long as you buy their phone, they get your money. I am going to have a conversation with the Telus Executive Team this week about this. I want to know what exactly is done. If it's white listing as mentioned. Then they can lock my device ID to a previously sold Telus device to keep these features active on my s23 Ultra. I had this done with my old Rogers s9+ on AT&T that was flashed to keep WiFi Calling and VoLTE working for that device while she used it.

good luck with Telus, I spoke with many people to get the freaking Vowifi option enable, and nothing can be done. Ive pposted on all possible forums to let people know.
Even the engineer team was aware of that and they didnt care.

Sad I personally know the ex VP of telus, but now retired...

I spoke to one of the senior network engineers at Telus after confusing my contact in the Telus Executive Office. What I was told...

Devices are not provisioned by IMEI but are by device model. So even a W flashed U or U1 will still show up as what it is because of the one unchangeable CSC. The crock about having to test devices before the model gets approved is a typical line but that is their excuse to limit what devices fully function on their network to help encourage customers to buy from Telus. However, devices and devices models will be added as time passes. I sent the engineer the IMEI's for my TMB U s23 Ultra and this is what I was told.

Not vetted yet but as explained to me over the phone. Devices and device model variants will be added to the vetted list over time. This practice was implemented less than a year ago now. There is no ETA for this and I am not aware of any way to bypass the IMS vetting list. Device refreshes take place every few days.
