Xperia Z1 C6903 no 4G option

Hi guys,

I have a Xperia Z1 C6903, so fully LTE 4G rady, but I can't get 4G option when I select my preferred mobile internet. connection.

It gives me WCDMA (preferred)/GSM option, but no 4G/WCDMA/GSM option I have seen on other Xperia Z1 phones. It is a sim free phone, I am using the Three network in the UK.

Can anybody help? Is there something I'm missing? I did a full software repair with the Sony tool but it made no difference.

Thanks,

I need some help to enable voLTE for Sony Xperia Z1 C6903. I know it is Hardware compatible. So I just want to enable voLTE and unlock bands which will be used in India (band3, band 40).
