Sony Z3 D6633

Great phone, loving it. Back is a little slippery but battery life is great, screen is great, form factor is great, etc.

There was an issue with it not working with UK EE sims but if you update to LATEST firmware you should be fine.

I got the D6633 which is the dual sim model. I have noticed that sim slot #2 is not capable of 4G but sim slot #1 is! Slightly bizarre because it means you have to swap your sim cards when you travel from country to country to maintain 4G access.
