Hi All,
I was researching for a tablet that would work on T Mobile USA ( insert my current sim, will t mobile charge more? ) LTE network as well as allow me to make and receive phone calls using the headphones.
It appears the Z4 wifi LTE version is the one. Is there any other models/brands cheaper priced that would suffice?
Many thanks
I have an unlocked international Z4 tablet now and am using my T Mobile sim in for data usage. Unfortunately mine does not have the native phone app on it so I cannot make traditional phone calls, but can use hangouts no problem. My bill did not change, just put the sim in, made sure the APN settings were correct and I have not had an issue.

Wow, thanks for chiming in appreciate it. I was looking on Amazon, and most questions I found and answered were that this model could dial out directly.
I was under the impression that US specific models were disabled to make calls but no the international versions.
Any other users possibly care to chime in and let me know if you can make calls with the Z4 SGP771 LTE +WIFI model?
Just came across this post on sony website..

I got the same response from Sony when I sent them a message asking about the phone app.
"I just received information that in the country where your SGP711 was sold, i'm afraid SGP771 does not have a built-in dialer and support for phone calls"
I have seen that you can flash firmware or different builds and supposedly this will have the default phone app.

I could be wrong, but I think its the SIM card / Network disabling the dialer perhaps. Glad I didnt cough up that much money , appreciate your reply a lot. :good:
I have created a list which still not complete showing all the models , but so far it appears the S korean model has the voice dialler function disabled, still not sure which ones work for voice over cellular and which dont. Id be interested if folks could add their model identifier and upc code and state in post if voice calls are possible over cell,

You could flash any international ROM for the Tablet or get hold of a dialer app.
FWIW: I am on the wifi version of the tablet (SGP 712) but just for the fun of it tried VOIP successfully. I use a phone for cell usage and VOIP.

Yes, but I primarily wanted to know if the LTE has a dialler , not VoIP.
According to Sony USA the us spec one does support voice via cellular, not sure I believe them however. Any have Xperia Z4 Tablet Sgp771us/B 1303-5541

i think it won´t depend on whether it has a dialer or not. the lte version is capable of making phone calls - period.
if the dialer was disabled or deleted so easily flash an international rom version (very easy with flash tool) or
install a dialer of you choice from the play store

Below is the version I recently bought from an amazon seller open box / used as their new stock was sourced form S Korea and apparantly is dialler disabled. My version I believe is to be from China / HK region.
Below is the one I managed to find that has the dialler enabled ( got lucky ) Using Xperia Service Menu App from playstore:
customization ver 1296-4830 R9C
phone software: 1292-0698_32.2.A.0.305
Global=LTECA- user ( non dialer version would state Global=nodial-user ) I think

Hello, I recently visited the USA (Las Vegas) and discovered that my UK bought (UNLOCKED) Samsung Galaxy S3 could not make nor receive calls in the USA. Roaming WAS enabled and I had an R symbol over the signal strength indicator. I have a Vodafone pay as you go sim card which I have used (as my main sim) over numerous years now. I have used it in other phones previously (HTC, Samsung, LG, etc.) over the years and they have all made and received calls in the USA (roaming) no problem. I did get a text message (eventually) when I was in the USA saying welcome to USA and calls cost £1.50, etc, etc. Yet when I tried making a call, I had an automated voice message asking me to contact my operator for some reason (can't remember the specifics). I've never had a problem using my Vodafone sim roaming in the USA and with previous phones, always made and received calls without any hassle (i.e. found a network automatically, e.g. AT&T, T-Mobile, etc.). Also, I visited Las Vegas last year with the same sim card but a different phone (HTC Desire HD) and was able to make and receive calls. I recall my brother saying that he had read something on the internet about the UK spec. S3 having hardware differences with the rest of the world versions, including not being able to work in the USA for calls. However, he could not find the site again. Has anybody else had this problem or know about it?

I have no idea about roaming in the USA...
However, I do know that the phone works on AT&Ts network, because I live in the USA & use the I9300 on AT&Ts network. The I9300 will not work on T-Mobile's data network, but should work on T-Mo's voice network.
That probably wasn't much help to you. I just wanted to confirm for you that the phone does work on AT&Ts network here.

Thanks brkshr, that was helpful. Good to know that a GT-I9300 does work in the USA.
I thought the USA had different models (SGH-T999 and SGH-I747). What made you decide to get a GT-I9300?
I may try again (next time I go back to USA) and if still the same, will try an AT&T sim. I must admit, I don't know anything about the different networks in the USA. Can I get a pay as you go sim for free? In England, you can get sim cards for different networks free and then obviously pay to top up.

You are correct. The U.S. does have it's own variations. I decided to buy the I9300 for the quad-core & I was hoping that Samsung would be more likely to release sources for it & update it faster. They do update the I9300 faster, but I prefer AOSP (Google's stock Android) over Samsungs TouchWiz & that's where sources come in to play. So now I wish I would have gone with a U.S. variant, because sources for the US variant are released. Oh well! (Sorry for the rant)
Unfortunately, we don't get free SIM cards here. The best thing to do is buy an AT&T SIM card online ahead of time. Then activate it on a prepaid plan when you get here. You need a Micro SIM card. They should cost anywhere from $5 to $15. Otherwise, you have to go into an AT&T store & buy their 'SIM Starter Kit' for $25... Complete BS.

Thanks again, the link (to Amazon) is very useful. I think I will get an AT&T pre-paid sim card as suggested. At least that way I can use mobile data (when wi-fi is not available) and not have to pay extortionate data roaming charges. Especially useful for mobile data assisted GPS.
One last question though. In the UK, you can keep your number even if you don't top up for ages. In the US, can you buy a pre-paid sim card, use it once, not top up for say a year and still be able to use the sim again, i.e. it won't be deactivated will it? That way I can have it as a holiday sim (I visit the US every year).

Well, isnt it a feature depending on your carrier (firmware)?
Gesendet von meinem E5823 mit Tapatalk
Yes this is carrier specific.
They will supply an app on Play if so.
Works on EE in the UK, it's a menu setting not an app.
Where exactly is the menu setting for wifi calling? I can't seem to find it on mine. If it matters, I got the Taiwan version of the phone and am with MetroPCS in the States.
For me it's in settings, under device, call. UK EE.
I am on EE and purchased my phone from Handtek hence preloaded with European Generic Stock firmware.
I can only assume @ewans has purchased the device from EE directly, which would have the EE branded Stock firmware which would have that setting built in by the carrier/EE.
I read when researching why I hadn't got this WiFi calling setting that carriers would be sending out firmware updates with these new settings (this finding is based on a different phone but the principle of carrier providing the update must be telling.) Looks like Sony stock unbranded firmware excludes this feature.

Yes, directly from EE.
Guess this confirms it (image attached.)
You require a carrier stock Sony firmware to obtain the feature.
If desperate for native WiFi calling with your carrier then you would need to update your Sony firmware to run your carriers version of it.
As long as your carrier supports WiFi calling and has the z5c officially supported like EE has then you will source the carrier firmware in xperiafirm.
The sacrifice clearly will be the added bloatware you will get with a carrier branded stock firmware.
Yep. I figured out that this was a carrier feature on my own probably around the time you mentioned it here. That sucks, cause my carrier, MetroPCS, has wi-fi calling available, but are highly unlikely to carry the Z5. Dang.
An alternative if you're in the US is to install Google Hangouts Dialer and get a Google Voice number. I switched from Verizon to T-Mobile here in the states, so I just ported my old Verizon number to Google Voice for a one time, $20 fee. With Hangouts Dialer, calls to US numbers are free, and if you're on Wifi, you can receive calls using your Google Voice number.

That picture displays a "T-Mobile" option. That makes me think that there is a chance wifi calling works on the T-Mobile network. Can anyone confirm this? If so, I will be purchasing this phone ASAP.
T-Mobile's website confirms that they do wi-fi calling. At least here in the States.

I know that they have wifi calling but I am 90% sure that this only applies to devices that they sell themselves. (Meaning that unlocked devices such as the Z5C will not have the wifi option). I just find it interesting that the phone itself has an option to select T-Mobile wifi calling if T-Mobile has had no plans to support it. Wouldn't Sony have removed this from the list if it wasn't compatible? Maybe there is hope for the future.
T-Mobile is also a carrier in Europe. The link in the previous screenshot might be referring to the places in Europe that carry the T-Mobile branded z5c. There appears to be a version of the firmware that is for T-Mobile on Xperifirm:
Maybe someone in the US on T-Mobile can try that out and see if there is wifi calling enabled? I am on the .32 firmware and don't want to revert back.
I flashed to T-Mobile Austria, and no luck on the wi-fi calling feature. Doesn't show up on the menu it should.
Hello, I'm on ee new phone but despite carrier saying they have activated and recent update I don't have this option. Those that do, are there Sip settings if so can you share them
EE Stock Firmware
I know this is counter intuitive to most on here but i want to go back to EE firmware.
I work in a Low reception office so WiFi calling had been a dream come true rather than running around the office trying to find signal. I also live in a 4G+ area which was also wonderful so I would like to get both back (broke phone and insurance have sent me an unbranded one with Stock firmware) so does anyone know where I can get the Stock EE Firmware I can flash via Sony's Flashtool?
I've searched google for 2 days and all I can find it posts and discussions on the newest stock update and/or rooting neither of which I want.
Thanks in advance.

This is something I am very much interested in as well, for similar reasons. I wondered if you made any progress on working out a process.
I about to buy this tablet, but have some concerns regarding the LTE version support with T-Mobile in the USA.
Can i use a phone sim with this tablet? **Just to be clear in regards to phone sim with T-Mobile i mean that i can use the tablet on a phone plan (voice+data) and not data only like they did in the Xperia Z3 Tablet Compact**
Does it support T-Mobiles LTE bands?

Hi,
1. Yes with nano sim. Userguide: http://support.sonymobile.com/global-en/xperiaz4tablet/userguide/
2. You can download the whitepaper for th SGP771 here: http://developer.sonymobile.com/downloads/whitepapers/xperia-z4-tablet-sgp771-white-paper/
And see if the T-Mobiles band is supported. (And I have no doubt that it is supported)

Doesn't say anything about T-Mobile in the US. Even when some tablets support it it is block by their network and if you put a phone sim card on it it will only do calls/sms and no data or you need to use a data-device sim card which doesnt support calls. Hence my question in regards to an specific provider.
I have a T-Mobile sim in mine right now. I can tell you that I DO NOT have a phone app in order to make calls. I am using a sim card from my second phone account. It connects to LTE fine and has good speeds on data. I am not sure if it's because the tablet is considered international or if it's blocked from T-Mobile. I contacted Sony and did not get much information.
I wish the OP or others would chime in about this. @legendindisguise may I ask what model yours is and where you got it from? What makes it more challenging is that the model number is SGP771 (right?) but for some it works for others not, so perhaps like the OP said the network is somehow blocking this feature?
Just to add to this post there is two model versions of the SGP771 with wifi and LTE I believe.
International version 43015809
Alledged US version 13035541
UK model ? Comes with keyboard 12957383
I just got a SIM card for my Xperia Z4 Tablet LTE (SGP771 / 13035541) on the AT&T network with a new AT&T account. This SIM is a new line with Phone+Data and I am having an issue making calls and making data connections (websites, etc..). I am still investigating and will update everyone when I figure something out. Odd thing is that the tablet connects to the network enough to display AT&T, the correct phone number assigned to the device, and 3 AT&T APNs, but nothing is working.

Hello there!
So I've been watching this forum for a solution a long time ago now and I've seen that there's a plenty of you, who didn't find any solution just like me. Because I didn't want to ruin my phone with unlocking and root. But I managed to make it work, not just volte, but vowifi too. All you need is another phone that works on VoLTE (and/or vowifi) in the same country ( same carrier is better bu not requirement). Put your SIM card in that phone, enable VoLTE (and VoWifi) and put it back in your Xperia. For me, it worked with a T-mobile HU SIM card (They don't even have on sell this phone ). It was in my iPhone 8 plus, it had working VoLTE and VoWifi. When I put it in my Xperia both options popped up in the settings and they both worked like a charm. My perso SIM is a Yettel HU one (I bought the Xperia from them), it isn't VoLTE enabled by carrier, so I'll contact them today about it.
Hope, you guys manage to make them work too

Tried that yesterday, didn't work still. If I am right, I believe that the issue is that there is no network provider in my country that supports (has customised firmware) this phone.
I do a bit of travelling every once in a while; so my best bet is taking my phone in by a network provider in a country where this phone is sold and get that network provider to flash their firmware in it, buy a local sim card and have them make VoLTE work in it. Then my home SIM card should work with VoLTE afterwards.

Sorry to hear that it didn't work for you. In my country we have only one carrier (Yettel HU) that sells this phone. They use the international one XQ-BC52 Customised EEA. I bought it from them, so mine is also that. Idk but it did work for me. So they don't have own firmware. They had on Xperia z3, since then they sell unlocked devices.
My model is originally the xq62 but i flashed hybrid of xq72 SEA to make it work but it didnt so i just kept using it as it is. I tried this on this and still it dosent work. Maybe if i flash same model as yours xq52 or the original 62. Too much flashing and checking.....

Telecom Italy appear to never turn on VoLTE if not specifically asked, even if your telecom app say VoLTE enabled. I also had to ask multiple times till i was able o talk with an higher tier "technician".
This remember me when at work (AASP) we need to talk with ACS to solve an issue with various customers Apple products. Sometimes only escalating to higher tier will allow us to solve something. Lower tier employee, even for ISP, sometimes are not able/allowed to disclose something

There's an android and ios disable option after it has been enabled, still no volte, but after I put it in iPhone (volte works) and put it back then it worked in Xperia too maybe that's a coincidence but I searched the internet a bit and I found some guys who made it work like this too.

Hello there!
So I've been watching this forum for a solution a long time ago now and I've seen that there's a plenty of you, who didn't find any solution just like me. Because I didn't want to ruin my phone with unlocking and root. But I managed to make it work, not just volte, but vowifi too. All you need is another phone that works on VoLTE (and/or vowifi) in the same country ( same carrier is better bu not requirement). Put your SIM card in that phone, enable VoLTE (and VoWifi) and put it back in your Xperia. For me, it worked with a T-mobile HU SIM card (They don't even have on sell this phone ). It was in my iPhone 8 plus, it had working VoLTE and VoWifi. When I put it in my Xperia both options popped up in the settings and they both worked like a charm. My perso SIM is a Yettel HU one (I bought the Xperia from them), it isn't VoLTE enabled by carrier, so I'll contact them today about it.
Hope, you guys manage to make them work too

What is the app bro?
I just received my Xperia 1 IV USA version today from FocusCamera.com today, I was a little skeptical if it was even the USA version, since it wasn`t shipping from Sony until next week, I originally had pre-ordered on Sony website, then with a little looking around I had found the USA version on ebay in-stock, then I saw the seller name and went to there website yesterday and verified with there live chat that in fact it was in stock and would ship, so I ordered and use next day air shipping, everything works flawless and actually has the 5G bands like my Pixel 6 Pro, so I can get proper 5g speeds, on Band N71, That was missing from the Global version I was using 2 weeks ago, now I need the Firmware from Sony so I can root. I`m a happy camper
Congratulations
What carrier are you using it on?

yeah I had t-mobile then I switched to GoogleFi last month, and wifi calling works perfect, inside my work place service from all carriers suck, since it big steel building, but my Xperia 1 IV will say emergency calls only, but I can receive calls and make calls and receive text, ad everything just like had full bars of carrier service.
I guess you were not able to root it?
To know exactly how capable the device is then its necessary take modem logs and let smart people parse it.

Unfortunately not, so this will be going back for refund, I can`t justify spending 1600.00 on phone and not able to root and do with it what I want with it, but there`s always the global version I could go back too, I`m going return it and wait and see if Sony does eventually allow it to unlock the bootloader, until then I`ll just use my Pixel 6 pro for now.
Can you please let me know if :
a. the NA model has Dual SIM support ?
b. Face unlock works (was told the fingerprint scanner is a bit finicky)

a. there is dual sim support, but you will lose the micosd card, because Sim 2 uses the microsd slot
b. no face unlock and both global and USA version`s the fingerprint readers worked perfect.
Is the 5G SA standalone or NSA only?
Should be both on all versions, USA model difference is mmWave support.
Would also like to know if they finally enabled 5G SA on T-Mobile with this year models.

You can know that without buying phone. Download the firmware with xperifirm, extract modem.img and use ELFextract to extract your hw variants .mbn file. This will reveal the carrier/band policy files (in policyman folder) which live in the modem. There you can see which bands are enabled for specific operators and if they are enabled for SA and NSA.

Thanks for the tip. I got as far as extracting mbn files. I can't seem to find ELFextract tool you've mentioned. I'm assuming this is different than readelf utility.

Thank you for confirming that Google fi does utilize Wi-Fi calling on the Xperia 1 IV.
