Attempted my research now asking question.

[Limeybastard]

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



type : tm-061-bv
