D6643 or D6633?

I'm looking at buying a Xperia z3 but I do not know which variant d6643 or d6633 choose (in Brazil only these are available) the resources of each tv or dual chip are useless to me and so I want to know which are likely to have more developers and sony support.
Looking in the forum I have seen more people with d6633 variant but without a good support and those which have d6643 are seeing to have kernel and rom's working in their devices just loosing digital tv.

D6633 is dual sim .
The d6643 I don't know. I think don't exist.

Yes it exists and has tv, but I just want to know which variant is easier to have developers support.

As far as my research has gone, D6643 is made for Brazil with all the LTE bands that D6633 has except D6633 has dual sim (as mentioned above.) As a matter of fact, of all the variants of the Z3 (aside from the D6616 which is tailor-made for T-Mobile's unique LTE bands and has all those T-Mobile apps pre-installed) LTE bands are the only differences. Support-wise the D6643 is only sold in Brazil so it may get less custom ROM's and stuff than the D6633 which is sold worldwide. It's your choice whether to get the single sim Z3 (D6643) or the dual sim (D6633.) Hope that helps!

the xperia z3v lte band is not as wide as on the model xperia z3 d6603 , lte band will work after flashing d6603 in

are you sure about this because most of the time you wouldn't be able to use your sim because of baseband mismatching

Xperia XA models?

Hi,
I am about to buy this phone so I was wondering what is the difference between F3111, F3113 and F3115? Which one is better? I am from Europe (because I think that is main reason why there is 3 bands).
Reason why I am asking this is because I have Xperia E3 D2203. In Xperia E3 forum there is ROMs made just for D2203 model and rest of models are not supported. I understand difference between single SIM and dual SIM, it is normal to be different.

VoLTE is provider specific. This means that a special firmware has that support built in... Are you saying that you're a Saudi user and with original FW it worked? Why do you need to change regional software?

I'm India user but got this mobile from Saudi.. Changing firmware to India will get volte support.. In other Xperia xz premium users I see volte support which are running Indian firmware.

Is it possible to enable volte in xperia 5 in india?

Is it possible to enable volte in xperia 5 in india? I bought xperia 5 j9210 from online. Unfortunately volte not working in india. is there any workaround? My wife is also using xperia 1 it also bought from online since sony stopped sales in india, volte is not working for that device aswell. Thanks in advance.

You may have to verify with your carrier if they support volte on the Xperia 1 & 5 at all?
if so, then then it may be a question of getting the firmware for your country/region flashed to the phone(s).

I am asking for your Xperia 5 only. Probably that same region's firmware (if it exists) on my 5 III might enable VoLTE. So far I have tried Global (Vodafone LC not Net Locked) and SEA but both haven't worked in enabling VoLTE.

I told you I flash jst Android 11 firmware in which I replace .OEM files

@yogeshpatel7 If it's not a lot to ask from you, could you PLEASE spare 5-7mins to go through my request here (https://forum.xda-developers.com/t/enable-jio-volte-and-vowifi-on-xperia-5-iii.4467977/) and see if you could help enable this for 5 III? I hope I am not asking a lot from you and it would SUPER APPRECIATED if you could help make this work. Right now my phone is practically a paperweight as I can't make any calls as Jio is a 4G ONLY sim and doesn't work without VoLTE.
