WiFi Calling for T-Mobile

[kassem277]

I just bought the F3213 from Amazon unlocked and I'm having many many issues after the master update. The most annoying thing so far is no WiFi calling support for the T-Mobile network, even though most people buying this product use it on T-Mobile.
If Chinese companies like Oneplus can enable the feature why can't a huge company like Sony do it?

Im going to likely return the handset if WiFi calling doesn't come to this phone in the next 2 weeks.

Since the phone it's unlocked it can't be done, for this to work T-mobile has to customize the update and enable this, not Sony.

Well, I'm not quite sure about that because according to T-Mobile engineers, Sony has refused to work with them on getting it to work. 

It can't be because it's simply unlocked, because many other phones that ONLY come unlocked have WiFi calling (eg. Oneplus one, 2 and 3)

Sony has dropped the ball here and their software engineers really need to get this feature working.

Do you have any source link with this information? or are you implying ?

This phone (f3213) has so many issues it's not even funny. I have repaired the software, swapped units out and tweaked settings, but this phones software is so defective.

1. When dialing a number, there is a 20 to 30 second delay before connection and a ring, even with full signal.

2. Many sound problems

3. Screen brightness is super high, and the lowest setting is bothersome to the eyes.

4. Camera delay in focusing and taking an image.

5. No WiFi calling enabled for T-Mobile or AT&T

6. Headphones not recognized when plugged in (tried multiple)

Many, many more issues. If an update doesn't fix the problems in the next 2 weeks, I'm returning this 3rd until back to Amazon.com. First Sony phone and my last.

I am quite happy with phone, especially for the price! The only concerns I would share is the lack of WiFi calling support for T-Mobile in the US.
Should anyone have a solution please share!

As you can see above, it's on T-mobile to work with Sony, they, T-mobile, will have to enable this feature, but if you want to think otherwise you can, but the facts are there, you can also check the XDA Forum.

Just hit the wifi calling update on Samsung Android devices(or may in other devices also) in India... So when we will get this new feature?? any software update for Xperia XA??

I have a xa F3111 running customised UK firmware in the UK on the three network and I have WiFi calling available through a app called three intouch provided by my network. Pretty sure on the T-Mobile network the device has to be running T-Mobiles own firmware have you checked the playstore or T-Mobiles website for a app...
