Sony Xperia Z3 D6646 or D6633?

[erasat]

I'm going to buy Z3 D6633 and use T-Mobile. One question, can T-Mobile Wifi calling work on D6633?

No, Wifi Calling is a proprietary T-Mobile App so in order to have it you must get a T-Mobile branded phone. D6616 has it.

BUT, I surely don't miss it, and now even less as hangouts already have the Dialer add-on in which you can call using your data or WiFi Conenction.

They are all more or less the same minus minor differences. Ultimately it comes down to different frequencies for different carriers.

As i read i need to add something. I know some users doesnt like to hear about root, but sometime ago one of xda users fohnd a way to "turn on" other lte/gsm bands. That way it seems that difference is made omby sony (however its not just software or its not in fw)

That way it doesnt matter which version u will buy, after root it will probably work with any carrier, anywhere in the world.

Ps. Its for only qualcomm based devices

What data speeds does the second sim operate at?

Hey,
I have this in the UK but can't get 4G on the second network sim (O2). I have it working for the first. Could someone confirm it should work on both?

I have rung up O2 and they confirmed 4G is up and running. I upgraded my sim so it's 4G sim and have downloaded the internet settings as suggested earlier. Anyone have any ideas?

Thanks for the help in advance!

The T-Mobile version is locked. Additionally, it only covers frequencies used by T-Mobile. That is OK if you are not traveling internationally, but it seriously limits your coverage if you want to use the phone in other countries.

This is a GSM phone. It is not compatible with Verizon, Sprint or other carriers using CDMA.

I don't know what search parameters you are using, but you can get this phone on Amazon, Mobicity, NewEgg and many other sources. I Googled the words "Sony Xperia Z3 Dual SIM" and got tons of hits.
