Pros: Large crisp screen. LTE works on t-mobile, which is the carrier I used. Steaming video on LTE or H data connection mode is smooth. This phone uses SIM card.
Cons: I haven't been able to activate the Wifi calling on T-Mobile yet since this is not a specific t-mobile version. Maybe some expert can shed light on this. Battery last about two days per full charge.
Summary: Bought this phone recently (my partner has the same was very impressed) Ok bad points 1s: camera is only 8mp with no flash yes thats right none atall sony made a gaff here ...as they are relying on the ability to use low light settings wich frankly arn't up to parr. Battery is 3050 mah sounds a lot but when your running essentialy a micro laptop with large screen it doesnt last long despite sonys promices!
Pros: Very fast, very good battery life. Nice design, None
Bought For Use On Vodafone Ireland - Working Perfectly

Summary: I purchased the Sony Xperia Z Ultra as a replacement for my old HTC Desire and to meet my need for a small but functional tablet (or phablet in this case). There were no issues setting up the phone in Ireland. A quick trip into my local Vodafone store to replace my standard size SIM card with a Micro-SIM took all of two minutes, no charges involved, and as soon as I rebooted the device I was up and running on the network. So far coverage has been excellent.
Summary: I'm a big fan of large phones/ phablets so this thing fits the bill just fine. I've had a few problems with it in the first couple of weeks of owning it, however these have mostly been fixed by firmware updates. (I'm still not sure about the optimized backlight problem where turning the feature off leads to continuous rebooting; I've just left it on to be safe). Pros: Amazing 1080p 6.4 inch screen with great viewing angles and colour reproduction.
A phone that only fits Sponge Bob's square pants, but...

Summary: It is gorgeous, only Sony knows how to make something like this, before Apple glossy products came along, Sony was already there, I had not brought a Sony product since the Sony UX micro PC back in 2008, and boy had they got their mojo back, new CEO, handsome guy he is. If not for this purchase busting my pockets, I would have also brought the Sony Vaio Tap 11. It is solidly well made, very clean, minimal design and very thin like chocolate McVities equally delicious.
