T-mobile vs unlocked: WiFi calling etc.

So I've decided to jump back on HTC ship with HTC 10.
The website says "The Unlocked version is compatible with AT&T and T-Mobile".
I assume that means radio bands compatibility only? And the features like Voice over WiFi will be still t-mobile branded only?
Asking existing HTC community if that's the case for the previous models?
And are there any other cons/pros of getting t-mobile branded version vs global?
Especially looking at OS updates frequency from HTC vs T-mobile.

Almost everything works for T-Mobile. From what I gathered of what was answered. Wifi calling, and VoLTE yes. In flight and RCS is a no.

T-mobile specific features like VoLTE and Wifi calling will be fully supported by the unlocked version on HTC.com

Thank you!
These are great news! I'm glad I went with unlocked version!
I'm tired of all the t-mobile bloatware and dragging of android updates.

Yea no enhanced voice services im guessing

I wonder if HTC will have interest in adding EVS and RCS down the road. I don't see why they wouldn't...

Wow this is HUGE IMO. No more requirement to load TMOUS FW or RUU so that VoLTE and WiFi Calling work!

Will it work fully on att Tmobile and Sprint???

Just wondering if it works on all carriers or should I wait for the unlocked version ? Thanks.

I have a vzw line. Popped in vzw sim. Then popped in my tmo sim. Data and calls work. Speed was faster on tmo sim though.

mine works well but i cant get video or any of the tmobile **** like that to work

I just picked up a Verizon S8+ (i had a T-Mobile one but just returned it) and i popped a T-Mobile SIM Card in it and i got a message saying "This is not a Verizon Wireless SIM Card" and it wouldn't let me use it. I thought it was supposed to be unlocked??

It is unlocked. After swapping Sims the only change you got to make is change preffered network mode from LTE/CDMA to LTE/GSM oh and go to APN and choose your new sim card apn. And thats it. Ive tried all carriers on my Verizon S8+ with no problems

What probably will not work on any carrier phone other than TMobile will be WiFi calling when using TM SIM.

Hey! I need to know if I buy a s8+ in Verizon, I will can use in Chile with my local carrier? I can read that you don't have problems changing the carrier in USA, will be the same if I use the phone with a Chilean Sim? Thanks!

I have a Verizon S8+ on AT&T unlimited service and it works perfectly. So you'll be good for Tmo as well. I have no clue about Sprint tho.

I have a Verizon S8+ on att and it works great. Does anyone know if I get HD Voice with this combination ?

Verizon unlocked S8 plus on T-Mobile working flawlessly for me

Verizon unlocked and works very well in France on the Orange network.

When I got my VZW S8+ I popped in my tmo sim first thing. It worked flawlessly out of the box. I didnt even have to add any APN settings as all of the tmo settings were built in. Awesome job sammy!

What about video call ect I'm having issues getting that **** to work is u pres *#77467# it says false on all the **** why won't the ims register that controls all that

I have an issue with s8+ using AT&T sim. The issue is that the phone shows a plus sign in front of my all incoming calls treating them as international calls. Does anyone know the solution?

The phones are completely unlocked, what you need to do is look up the VPN settings that T-mobile, or at&t use for their phones and set them accordingly. Though some functions might not work with non-Verizon carriers through changing these functions. (messages, video calling, etc..)

Thank you all. I bought the s8+ from Verizon out right because I wasnt sure if I was going to stick with them. And it looks like I am moving to t-Mobile this month, I was going to look into flashing the firmware, but I was worried since I used Samsung pay like crazy. So I am fine with just disabling the verizon apps and going from there.

Anyone know if the phone will still get updates if I swap in a T-Mobile SIM, or a Verizon-compatible one from Straight Talk while still on the VZW firmware?

It will if you use the VZW software update assistant. I've done 2 updates this way on my Verizon S8+ with my tmo sim in there. Works fine.

Sounds good. Do you know of the Verizon phone has all the bands of the T-Mobile version?

Fully work - no. Things like HD calling and wifi calling wont work without t-mobile software.

Volte?

Anyone using volte on the XZ2 Compact? I noticed my lte+ drops to H during calls so it appears it is not working. I don't see an option for it either in my settings. Using the duel sim version.

I am using it, normally if you do not have a setting for it, then it means that your carrier do not support it for the phone model you are using, or it is not activated for your number.
I have the setting but have no status icon for it, so I wrote to Sony who said it is the carrier who decides if a status icon should be shown. And they explained that when calling someone the call screen will write VoLTE if the call is using VoLTE, and my does [emoji3]

Are you using the single or duel sim version? Carrier?

Your device needs to be certified for VoLTE use with your carrier and needs to have the proper OEM.sin file flashed to it if it does in fact support it.
At this time in the USA, only Verizon is certified for use with VoLTE. T-Mobile support may be coming in a future update and AT&T will never be supported.

Why in the hell does the XZ1 Compact support T-Mobile VoLTE, but the XZ2 Compact does not. W.T.F. /rant

Any updates on VoLTE on T-Mobile?

Any updates? I want to use it on T-Mobile and no VoLTE would mean that I have to look for a different phone. Don't want a repeat of the horrible experience I am having with my Z5C

Wifi calling support

Does anyone know of the Zenfone 5 series support wifi calling? I'm looking to upgrade from my ZTE Axon 7 and I really need support for Wi-Fi calling with my next phone.

I don't know. But can't find an option for this here and my carrier supports this.

I have had an unlocked ZenFone 5 for 2 weeks now,VoLTE and WiFi calling is not provisioned yet I think it will come through shortly great phone though.

Now that the Zenfone 5z is out in the states, thought I'd ask again if the phone supports wifi calling, specifically on T-Mobile.

No, it doesn't support WiFi calling on TMobile. But it does support VoLTE.
This is from the manufacturer on the Amazon listing.

It supports! I'm using Vodafone TR (so probaly the other countries' support too) and when I activated aeroplane mode with wi-fi (provider was Turkcell), I've received calls. But I can't remember how was the sound quality. ZE620KL

Well these are conflicting answers.
They say it does, but only for carrier models?

Hocam merhaba Vowifi ayarını nereden açtığınızı yada nasıl ayarladığınızı tarif edebilir misiniz

Verizon version

The unlocked version of this phone doesn't seem to be compatible with Verizon's 5g mmwave and many features like wifi calling, hd audio, and hd video calling are not available on the unlocked 5G like the original Razr that was a Verizon exclusive. Any help is appreciated. This is highly frustrating. Just don't know why these features can't at least be enabled while just using 4G LTE.

Wifi calling is unsupported by verizon on their end, mmwave is unsupported because afaik verizon is the only one that tried pushing for it. As far as hd audio I'm assuming you're talking about VoLTE which mine does perfectly fine on Verizon, you may have to call verizon and have them switch your line to LTE only as that's how my line is set up due using oneplus devices. As for video calling I'm really not sure how any of it works, I thought it gets routed through duo?
