I just got my Blade X1 5G, and it says 5G in the status bar, but when I look at Signal Check or even Speedtest, it shows I'm actually only connected to LTE. Does the phone just say 5G, and not have 5G? I'm aware it's DSS 5G since it's Sub-6, but it should at least register me as 5G. I am in a "nationwide 5G" area too.
I'd recommend confirming that your device software is up to date, as well as completing any carrier up dates that may be needed. If you're still experiencing issues with your 5G connection, then you may need contact the Visible Care Team for further assistance.
