S22 Ultra unlocked still no Android 15 update

Why can I not get the android 15 on my S22 Ultra unlocked phone?

I've been checking and checking for updates and still nothing.

@user2V9N7o45kB What is the model name of your S22 Ultra? Does it end in "U"? Go to phone settings -> About phone. 

Where did you get the phone? and have you changed carriers? 

[user2V9N7o45kB]

Yes, it does.  When I paid for the phone, I was told that it would automatically be unlocked in 30 days, that was about 2 years ago.  I have contacted the Provider where I purchased the phone from to verify that it is unlocked and they said yes.  I'm no longer with them and am with a new carrier that also told me that since I brought my own phone, it would not be locked....

Your phone has the original carrier's firmware installed. Now that you are on a different carrier and have that SIM installed, your phone will look on the current carrier's update servers for an update. But it will look for an update for the firmware installed on your device. It will never find original carrier's firmware on current carrier's network.

I still have the original carrier's sim.  If I put that back in, will it update since the sim still works?

@user2V9N7o45kB That should work as long as you check for the update over wifi with the original SIM installed.

Ok, going to try it now and will get back to you.

Wow, this is going to take a while.   Apparently the carrier I have now, does not believe in updating security or anything else...... I'm now on the 3rd update which is 33 and now have UI 6.1 and also now security update number 34.  I wonder how many more there is going to be before I can get Android 15......

@user2V9N7o45kB It has nothing to do with your current carrier. It is because of the firmware from the original carrier.

Is there anything I can do to change that?
