Can you share a screenshot of your Software Version Page? Also if your original device is from Verizon and you have verizon sim card installed the device Will update to show that the device is U1 but it will continue to show VZW/VZW/VZW as soon as you install verizon Sim card in it. Samsung has not enabled ability to go from one carrier specific to another carrier specific device yet. It also took a long time for S20 to get that feature based on historical threads I read.
Both U and U1 only support single sim, I can't find the SIM card manager in settings, would G998W support dual sim?Okay, post deleted, but it's probably worth noting that you don't know what the G998W is. Because it's the same phone as the U and U1. During the One UI 3.0 Beta on the S20 Ultra, I flashed G988U on my G988W, and when the beta continued onto the U1, I flashed those firmware files as well. The Canadian S20/S21 is just a non branded T-Mobile with more supported radio bands in the firmware.
If you actually look at the carrier info for the S20 Unlocked U/U1/W firmware, they all say XAC and XAA at the bottom no matter whether it's U/U1/W. They are all the same phone and Samsung even uses the same firmware merged, just different radio bands, and because Canadian radio bands support ALL bands, it makes the W firmware the a merge of both U and U1, so it's actually the better choice from what you have posted because it supports every U/U1/W the best. So your post is relevant to the W models whether you want to accept it or not.
That's why I included a link to the firmware, because it's the same device, same flashing process, completely same procedure, so this thread IS relevant to the W models even if you said U and U1 only, the W is also included in that even if you didn't say it was, doesn't make it true.
Also the only difference between U and U1 is U is unlocked but INCLUDES carrier bloat, U1 is unlocked and has NO carrier bloat.
So, closing info here.
U1 is unlocked, no carrier bloat, US radio bands
U is unlocked, HAS carrier bloat, US radio bands
W is unlocked, no carrier bloat, ALL radio bands
You just need to make sure it's the SM-G998W for AXC and it's the best choice with no bloat.
Just because you clearly didn't know this about the W phones, doesn't mean you gotta get all snappy, I'm just trying to help the community.
After checking from samsung official site of Canada, the result is "*Use of eSIM/Hybrid SIM/Dual SIM on Galaxy devices has not been enabled in Canada."
The only benefits I can think of would be enabling Samsung features that Verizon disables, like the Spam Filter, and removing some of the bloat that might be impossible to remove on the VZ version.
