Ever since the latest update, my S25 FE has been unable to connect to the T-Mobile network. I had no issues prior to the update, but now I can't text or make phone calls. I can connect to WiFi and Bluetooth perfectly fine, but WiFi calling is unavailable. When I try to make a call, I get an error message saying my phone isn't registered to a network. I have already gone through several troubleshooting efforts with no resolution (i.e. toggling airplane mode, restarting the phone, resetting netork connections). Is anyone else still having this problem? Has anyone discovered any resolutions?

Hey @horselovermt and welcome to the Community! I read that you are having similar issues with being unable to call and having issues with your Bluetooth and I could imagine that must be frustrating. I would recommend to you as @Pianodude58 stated to the author to reach out to your carrier as Samsung would have no further troubleshooting with issues regarding being able to make calls and send texts. Thank you for posting, and I hope this gets sorted for you soon! 🙂

This is from the 8.5 update trust me, I had and s23 ultra and blamed everything on my carrier three network but this happened instantly after I updated to 8.5 my sim worked perfect in other phones I ended up upgrading my phone I bought the s25 ultra and I have not updated to 8.5 out of fear of this happening again and to confirm this my wife has an s23 ultra and her phone was working perfect until today when she accidentally updated her phone to 8.5 I tried everything with my phone changed sims esims reinstalled a fresh version of 8.5 forced lte factory reset network reset, and now since my wife's phone has gone the same way after the 8.5 update it's confirmed the update messes with the phones, so if anybody is reading this do not update to 8.5 if you did not already.
