Can you test it?... Because if it works, that means C6903 may work on att too

I flashed it on the c6833. It boots fine but no at&t LTE. So no I did not enable the missing bands.

You can actually check the bands available by dial *#service#*...
So I guess the switching baseband thing doesn't work for lte

Yea the bands on the service menu didn't change either. There was no 700Mhz band (b17).

Phone has poor reception

I just bought my Xperia Z Ultra, and it seems to have worse reception than my HTC One even on the same spot. The HTC One is set to use WCDMA and GSM which is the same as my Xperia Z Ultra right now.
So in theory it shouldn't have any signal differences. Does anyone know how to fix this?
What firmware baseband are you using and do you use bumper?

I'm using the C6802 and no I'm not using a bumper. I have a feeling my device is defective as the touch screen seems to randomly have ghost inputs.
Really disappointed in what I have, hoping that I just have bad luck.

SIM unlocked, yes. The bootloader should be locked when you purchase the phone.

Sony will allow bootloader unlock if bought from sony. carrier usually does not allow unlock bootloader .

SIM free but Vodafone Germany firmware (based on .55) has unlockable bootloader allowed: YES (probably bought contract free drom Vodafone Germany). Though I don't know about phone on contracts from Vodafone Germany (SIM locked) if they have allowed on not unlockable bootloaders.

Sure, buy an unlocked version. All carrier branded units will not be bootloader unlockable. I have read that 3 branded in the UK has the ability to unlock the bootloader but the safest bet is non-carrier branded.

I can confirm that in Norway at least Telenor is allowing unlocking of the bootloader. Word I have heard is that here, none of the carriers lock their bootloaders, or at least with the Z2 none of them are removing the ability to unlock.
