Hi all, I am a complete noob with it comes down the wcdma vs gsm. I want to buy a xperia x10 on amazon but all i am seeing is wcdma. what i want to know is can a wcdma xperia phone use a gsm simcard?
Thanks
wcdma is aka 3g and gsm is 2g so a sim card will work on it
Thanks just wanted to make sure, because my country uses mostly gsm phone and i am see pretty good deals on the xperia x10. but the comments are saying wcdma/gsm. dont want to buy and the phone causes problems.
I am planning on purchasing the Xperia Z Ultra for use in the US. I have noticed that Sony has several models of this phone -
Sony Xperia Z Ultra HSPA+ C6802
Sony Xperia Z Ultra LTE C6806
Sony Xperia Z Ultra LTE C6833
My intention at this point is to use it with T-Mobile LTE service. I realize that the C6802 will not do. How about the other two? Would both C6806 and C6833 be fully LTE compatible on T-Mobile US?
At some later date I may want to use it with AT&T or AT&T MVNO. Would both C6806 and C6833 be compatible with them?
Also, I travel often abroad and want to be able to purchase a local SIM cards in the countries I visit. Which of the two LTE phones will work better internationally?
In non technical terms - what’s the difference between the C6806 and C6833 and why Sony has both?
Which of the above two has the same network compatibility as the Google Play version?
Thanks in advance for any input and help.

Hi. I must say that I'm on t-mo and I bought my C6802 ultra since it came out and I has to say that when it comes to internet speed on HSPA+ not one I've had a complaint HSPA+ is fast enough for me here in denver co. Unless you really want to have LTE. I use slingplayer internet radio without lag. But then again not all phones are the same meaning may be I'm a lucky one that my phone s fast on my network.

I was sure I made a thorough search... I must have overlooked it.
Sorry and thanks for the link to all the info I need!
Any T-Mobile USA owner now there, can you please confirm that with an active T-Mobile SIM, can you do Wi-Fi calling on this Sony Z Ultra? If so, was the Z Ultra a Sony version, or GPE? Thanks!

Tmobile wifi calling working only with Tmobile certified phones., which is on sale in tmobile stores.
Xperia Z Ultra and Z Ultra GPE don't have that future.
If you have a choice buy Sony version of Z Ultra. Why ? There is many posts about it.
Regards
Well...
Here is the thing, I have a MetroPCS Alcatel OneTouch Firece, I unlocked it, put my T-Mobile SIM into it, and I was able to make Wi-Fi calls.
Obviously, this phone is not a T-Mobile certified phone, it does not have any T-Mobile software on it, and, when I am in-door with no cell signal, the phone shows MetroPCS, so what gives?

2. Are Xperia Z2 4G bands compatible with Verizon's bands in model (D6503)?the specs shows band 4 &13 is already included in D6503.
3.How can I get the APN for Xperia Z2 in order to activate 4G LTE?is it from Verizon or another source?
Big thanks in advance for the help and my apologies for bad English.

Thanks a lot for help, is there any compatibility issue that prevents Verizon from activating? or just Verizon being itself? I always have bad experience when it comes to their technical support.
Regards,
Its Verizon being Verizon. They won't activate anything not officially Verizon

most of the things should work
I did look on this specs first, after I got it seems like there is something additional. There is one spot I get a super connection but 90% of the time weak or no Service at all. I have tried many phones before but none of them even had such bad reception. And there supposed to be even the Tmobile 5G 71 Band. It looks to me someone sold a restricted fu.... Asia version without mentioning it
go to settings and all the way down you should see your model number. Considering that USA specific is not out yet you most likely have asian one which is XQ-CT72. EU one is CT54.
But those should work on t-mobile network, most of the bands are there. And those are low bands, so longer range.
It runs at limited feature support. Sony disables VoWIfi for US models and many other features including Bluetooth features such as Bluetooth meta data.
Sony blames T-Mobile for limited feature set. you will need to root your phone to hack up the build to enable VoWifi and other features.
This feud between Sony and T-Mobile has been going on for the past 10 years and Sony still playing ignorant to US market.
if you don't care about such limited feature set, Xperia 1 IV should still work on TMO
I just got my phone yesterday and realized the same thing happened to me, I didn't have service where I used to but I managed to get it working by: going to settings, then network and internet, then Sims, scroll down to access point names. And two options should pop up, I changed mine to T-mobile US LTE.. And restart, which worked for me.

Are you saying the the imported version of the Xperia 1 iv does support VoWifi or neither one will on any USA carrier

that is correct, the issue is more related to Sony software rather than just the region. the only way to get VoWifi is to root your phone and disable sony software limitations

Is there a guide for this? Not having wifi calling is the main thing holding me back from pre-ordering

yeah this guide should work, its for the Xperia 1 III, I would think it would work for the IV, I just switched to goggleFI to get Wifi calling with out having to do anything.
Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file
I live in Canada and I have a BC72 (Asian version). I am struggling to get VoLTE and VoWiFi working. I know that mbn file is the key to getting IMS support and sony seems to block some carrier mbn files (only mbn in sales areas are available). So...
forum.xda-developers.com
I have been using the XQ-CT72 here in michigan on GoogleFi, which is basically t-mobile, in my town where I live, I get 5G without doing anything to the phone, but with that said, I work 20 miles out in rural area and apparently from my research tmobile use band 71 for 5G in rural areas, I can get LTE+ but no 5g at work, my Pixel 6 pro can get 5g but its like 1 to 2 bars that`s it, but with my sony I get full bars of better signal on LTE+ with my Sony, since the Sony is missing the n71 band for 5G, but I`m fine with what I get, since at work I` m on wifi anyways, I`m happy with my purchase, I originally had the US model on pre-order and the release date was pushed back to Sept. 22-23, so I cancelled my pre-order and bought a new one on ebay for 1069.00 compared to sony wanted 1599.00 for US mode
EDIT: I ended up send it back to seller, the 5g icon was not really 5g, if you're in the USA I would wait and buy the USA version, which I pre-ordered from Sony website, expected ship date is 22-23
moving to GoogleFI is the best option to use this phone in the USA. it will utilize Tmobile USA and have all feature enables.
Can anyone comment on Verizon compatibility with this device?
If really like to save some money and not buy the bootloader locked na version (if locked is still a thing)
Thanks

Only way to know for sure it to just buy it and try it for your usecases. Just buy it somewhere with a good return policy. I bought mine on Ebay with a 30-day return policy and so far it works fine on AT&T. Just make sure you do the trick where you disable dual-sim. (Google the details, it's somewhere here on XDA or on Reddit).
I bought my USA variant phone a week ago, and everything on T-Mobile works with the exception of Wi-Fi calling. The only alternative we have is to stop using T-Mobile and switch over to Google fi which does support Wi-Fi calling. Other than that my phone is flying super smooth and with fast performance like I've never believed compared to my old LG v30 Plus. I'm definitely impressed with this phone.

I'm using mine (XQ-CT62) in the Verizon network. Reception is not the best in the area where I'm but it works with no problem
Is that a coverage thing most likely, or the device itself? Rural area?

From a technical point of view, the phone should work on all carriers in the USA without issues, (with the exception of the Sony/T-Mobile Wi-Fi Calling issue that forces those who want Wi-Fi calling to switch to Google Fi, Mint Mobile, and other MVNOs).
Whatever service is in the area should work. Verizon will provision your phone to work with it's network. CDMA based carriers are supported per Sony's phone settings, so I would just go for it.
