How do i get 4G lte working with the fingerprint sensor on my XZ Premium?

[Android Central Question]

I purchased the US model for the warranty and just flashed the UK firmware from XperiFirm so now I have the fingerprint sensor. My issue is now I can only get 4g / H+ to show and I'm getting speeds of about 5 Mbps. I switched from my HTC M8 and it was getting lte all the time with 60+ Mbps. I'm assuming it's due to the uk firmware so does anyone know how to get both to work? Thanks.

Check the bands that the particular model number of your phone uses (online - there are a lot of sites - https://www.frequencycheck.com/mode...remium-td-lte-g8141-sony-maple-ss#frequencies is one. Then check the bands your carrier uses. (4G can run from 2mbps to over 40mbps, depending on the phone, the band and how close the server that you're downloading from is.)
