Hi, Bill. Regardless of your locale, I do not think this is just you. I also have an A53 here in the US, and have tried all the suggested solutions to fix the "no service" issue, but it is still without service. Sure enough, I moved that SIM into an older phone I had (A51), and my service is perfectly fine. But I cannot stand the back-and-forth with my data, let alone the fact that my backups aren't backwards compatible with an A51 that isn't receiving any more updates.
I have used Samsung for years and have never had an update do something like this, but I'm very aggravated and disappointed. All Samsung chat did was tell me to visit a service provider or send in my phone for repair, but I don't have much any money to do that. And yet still, I wonder, how can it be a hardware issue when the only thing that happened, the only altering variable, was that One UI 8 update?!
The fact that this update had to be pulled from some of their S line phones for firmware issues in October doesn't help to support anything either.
For now, I'm still trying to diagnose, but I might just be stuck waiting for a patch in the desperate hope that that's all it is... but who knows when Samsung will release one
