My S23 ultra hasn't received the one UI 6.0 update after network unlock

Hi, my S23 ultra haven't received the one UI 6.0 update after network unlock , any idea what's going on?

I left at&t and have Verizon now

Alright, that explains. In this case, you need to ask someone for their active AT&T SIM card and then check for software update and install it. After that you can put your Verizon sim back and use it.

Well, if that's the case, then why my phone is only asking for software updates via WiFi only? I couldn't ever get it to software update unless WiFi is connected, which leads me to believe that it won't matter much what sim card is inserted. I'd still try that att active sim card solution though.

I have done this years ago with another galaxy phone and yes, with AT&T SIM card you will need to be connected to Wi-Fi as well. The way I did it, is that I went to AT&T store and asked a sales guy a favor. So, he gave me a working sim card and I connected to wifi in the store and proceeded with all the updates phone offered.

That's very helpful, thank you so much.

If the update situation with AT&T devices as it was years ago, then you might have to do this every update you want to install.

I might as well get an att sim card then, as this could be annoying to them at the store..

You don't really need to update on monthly basis, unless there is really important security fix. Just follow the tech news. Update every 3 months or so.

I just went ahead and switched carriers, went back to at&t and boom! Problem solved! Got the one UI 6.0 already with every other security update.. thanks for your help

Yeah ur core OS was setup for the AT&T network, there are different protocols that AT&T & Verizon use to operate the basic phone features. It took T-mobile almost 3years to figure out how to switch sprint customers to T-mobiles network.
