[Q] T-mobile Wifi Calling workaround???

Please forgive my ignorance....Is not the wifi-calling issue a matter of having a kernel that supports it and having the apk that works with 2.3.5??? There are other 2.3.5 roms that work with T-Mobile's wifi-calling. I am in no way a developer nor do I understand much about this. I am simply offering what may or may not have already been thought of.

It won't be just an apk once tmo releases it for SGS2.

when you say other roms are you by any chance talking about a rom for the gs2 or are you talking about other android tmo phones.

What I mean is that FOR NOW T-Mobile's wifi-calling is a matter of having the app and a kernal that supports it. There are other 2.3.5 roms that run the wifi calling app so it seems to me that it wouldn't be that hard to get it running on this phone. Who knows how long it will be until T-Mobile get this sim card wifi-calling going.

It's actually a bit more than just the apk and kernel. You also need a RIL (radio int. layer) that supports the handoff. RIL is not open source, which is why you don't see oodles of TMO phones with wifi calling.
If it was just apk+kernel, wouldn't every phone on TMO have wifi calling?

WiFi calling will be baked into the OS rather than just being an apk.

That doesn't help, it hurts. Now T-mobile has a premium phone with wifi calling and the other variants that have the old version. There is no need for them to RUSH to get it to us, the amaze people have just become T-mobiles "beta" testers as the alpha with the devs and employees is done. Expect delays and pushbacks now on our phone. Like I said before, and please T-mobile prove me wrong, Samsung is HORRIBLE with updates and we will be lucky to see this before the new year.

Ugh even my gf's g2x has wifi calling.

Did everyone here get the sim card? All three of us (family) got new sim cards when we got our new phones back in Oct. Supposedly required for the wifi calling.
Is this wifi calling they're rolling out supposed to be like UMA on BB? Where it will hand off between wifi and cell? Had the BB a long time ago and UMA was pretty slick. Had the original Galaxy S with wifi calling previously and voice was sketchy, delayed. But it was great for receiving texts in our crappy location.

Tmobile wifi calling?

Can Tmobile wifi calling be enabled on the GSM Gnex? If it is not natively available, I see that Tmo' just released the official ICS ROM for the Sensation and I am hoping the libs are the same and can be ported!

Anyone?

I wanted to bump this to see if anyone has new info. It has been a while, so my fingers are crossed!

no it doesn't work on the nexus I tried to port it but nothing unfortunately I only got it to work on my sensation with cm9 not the nexus tho

If Tmobile ever sells the device we absolutely will see that functionality, however I am hoping someone else can figure out a way to get it working in the mean time.

T-Mobile won't ever sell the device. That's the main reason why. Add in the fact that it's extremely hard to port the functionality to non-T-Mobile handsets and I wouldn't ever expect WiFi calling on the GNex.

Does this phone support advanced calling 1.0?

I've searched everywhere and no one seems to have a legit answer to this question.

I'm really hoping the reason they are taking so long to push VoLTE to more-than-capable devices like the Note 3/4 is that they are just putting it in the Lollipop update. Otherwise it's unacceptable.

I'd rather they do it right. I can live with 3 g calling because its got better signal at the house anyway. LTE goes up and down. I assume because of tower load

Agreed. I would also bet that the initial phase won't be a great experience
..lots of dropped calls for the first few months on VOLTE. I think we will be glad we have the old style simultaneous voice and data for the foreseeable future.

Your link only shows that the note 4 is not presently using advanced calling. It does not tell me if the phone is capable.

It is capable. There is a VoLTE configuration menu in the directory. Probably needs a software update but it will eventually be an option. Although from the reviews by other devices that already use VoLTE I have seen it might not be such a great thing...lots of dropped calls if you transition from an LTE area to 3G (sometimes just walking into a building).

That link shows all of the Verizon devices that are currently VoLTE capable. The Note 4 is not currently VoLTE capable.
A future update will make it VoLTE capable.

No worries...I think it will be a great feature, eventually. I have heard some horror stories of dropped calls on the devices that actually have it. Apparently the pass off between VoLTE and the other bands (like when you enter a building) is a problem. The fact that it is version 1.0 now was a big factor in me not going with a Nexus 6 and choosing the Note 4. No voice and data until VoLTE rolls out is a joke. That was standard functionality 4 years ago...huge step backwards IMO.

I completely agree, i to chose to go with the Note instead of the N6, i just hope i dont regret it. The issue with the VR was a joke also, if you cant configure your kernel correctly after what i assume was at least a year of research and labs, to work with a company that you have full access to necessary info...i just hope i didnt pick the wrong unit.

If stands true someone posted when we get our lollipop update in alleged May release Advanced Calling 2.0 will be on our phones. I have not found anything stating the truth to this, accept that it possibly adds wifi ability.

May?!! Can you guide me to this post?

It was just someone claiming that a Verizon rep told them it would be released in May. Nothing even remotely reliable. You can see the post here if you really want to.

So I got the Lollipop update yesterday (in JFK between flights! yikes!) and I notice the Advanced Calling is there, but I haven't activated it.
I had heard some good and some bad from previous users. Did we get something good or should I leave it off?
Is it something I can DE-activate if it sucks?

It is capable and available. The option must be checked. Also, the free add on must be added to your account. On the my Verizon app it is in the services section.

It was enabled in the NK5 stage 1 update applied to our phones on upgrade and was carried forward into Lollipop. The function shows as Advanced Calling in our settings but as stated does require Verizon to activate the service on the account. The following is from the Lollipop system log and shows the system is looking for it if enabled.
D/RegistrationManager( 1647): isVoiceCallAvailable : result [false] pdnType [ims] isVolteEnabled [true] isVoPSEnabled [true] isSSACEnabled [true] isPublishFailed [false] isDmVolteEnabled [false] isInviteForbidden [false]

I have been trying to figure this out for an entire day. Turns out, this feature is not available for prepaid accounts. Cannot enable the option in settings because it tries to add the feature through the My Verizon app.

International ROMs

I see there are international ROMs which will work on the t-mobile s6 edge. But based on my reading and if I understood correctly, wifi calling and fingerprint scanner won't work on these ROMs?
Wanted to try one but those are important features to me

The only thing that you will miss is WiFi Calling which will only work on a Tmobile based rom. As far as fingerprint is concerned the only way it won't work is if you aren't on a 5.1.1 bootloader and baseband. If your baseband version is COF6 or COF8 you're good. I'm currently on a Tmobile normal S6 rom on my Edge because I personally like having 5 signal bars and VoLTE. You will be missing the Edge features though which is why I'm contemplating going back to my international rom. Unfortunately there are no Tmobile S6 Edge based roms so you will have to compromise. But if you absolutely need WiFi calling then you will have to run a Tmobile based rom.

Got it, and thanks. Yeah unfortunately I need wifi calling because I don't have reception in some areas of my house. That sucks hopefully some devs will put out a t-mobile base rom soon. I think I saw on another thread that one is in the works

WiFi Calling and VoLTE and AT&T

It's my understanding that these features (advanced calling, like WiFi calling and VoLTE) Doo not work on unbranded devices like Pixel and others. This was the case with my unbranded SM935F or Galaxy S7 Edge until we got some files, an appropriate CSC, and also had AT&T switch our account to an IMEI of an AT&T branded device that had working WiFi Calling (others have apparently just called AT&T and had them provision WiFi Calling)
Note: for me, I have a business account so I could just go into my business portal and put in an IMEI that I got from an S7 Edge model in an AT&T store
I am attaching the files that we needed to add to our system to get WiFi calling to work on AT&T. I think I remember all I had to do was to add them and make sure permissions were correct
Here is an IMEI that I saw on another post that may work ..... But I do know that the AT&T system needs to recognize your phone IMEI as an att branded device that has working WiFi calling. So if you aren't business customers it will require a call to customer support.
Possible working IMEI:
Mod edit: Removed
Any Pixel AT&T users that could try this and report back would be greatly appreciated!
Btw, I'm not completely sure which files are needed in the Pixel as compared to the S7 Edge .... I would have a backup available

I obviously could be wrong ...... But I'm 99% sure that what you are saying is not true for AT&T and maybe even other USA carriers!
I KNOW that I'm right for S7 phones and ROMs .... And the problem is so pervasive that they have even been able to get unbranded S8's to obtain WiFi Calling on AT&T or other USA carriers (even though WiFi calling works great on branded S8 phones)
AT&T users a different mechanism to provision WiFi calling than other carriers

You are correct that AT&T does not allow unbranded phones to use those features. It's all BS too. I have great LTE coverage but many times I will go to make a call and have crap service because they have canabalized a lot of the hsdpa towers for LTE. Then the switch back to LTE can take forever. And I don't care what they or anyone says AT&T's hspa+ is no where near as fast

None of this works, as AT&T blocks access to VoLTE on Pixel phones. Denies me the use of Numbersync for my tablet and android wear 2.0 watches. AT&T service techs keep promising to fix it and try to force it to work, but still blocked. It is simply a situation for Google to get the Pixel certified for the AT&T network, which is problematic, as AT&T uses a non-standard protocol for HD Voice that is unique to their network. So, as best I can tell, AT&T has to release the source code, for a price, I presume, to Google to add to the phones and then pay for the certification process with the FCC. Seems a stand-off as long as Google has an "exclusive" arrangement with Verizon. So for me, I'm pissed not to have numbersync for my devices, but unwilling to give up all the advantages of the Pixel phone.

That's why I switched to T-Mobile.

So there is no way to get VoLTE on the Pixel XL with AT&T then?

Not currently

If AT&T carries the upcoming Pixel 2, is it possible Numbersync would start working on Pixel 1 devices?

I doubt it. They only support advanced features on devices sold by them so it's not as if older Pixels will suddenly be grandfathered in just because they start carrying newer ones.

This annoys me to no end... If I buy a phone from att, do they have to give me an unlock code when the phone is paid off? I really need WiFi calling for a trip I make multiple times a year

Yeah according to a rep I spoke with, the pixel 2 will support Numbersync even though att isn't selling them. There are, however, no plans to change the restriction on the original pixels.

I'm in the same boat but I'm genuinely curious - if I don't need wifi calling - is it really a big deal not having VoLTE? I'm taking in terms of better signal or faster LTE internet speed. Or does VoLTE is just having clearer phone calls? I guess what I'm asking is what other benefits are we losing (on a technical standpoint)

Late response but as far as AT&T goes besides VoLTE what I experienced on my Pixel XL was random issues with group text (MMS) reception from certain individuals from other carriers.
In particular it seemed as though if senders of MMS texts to a group chat that I was participating in sent a text from a carrier like T-Mobile and they were using Samsung devices with VoLTE and enhanced LTE stuff enabled on their end I'd not receive the text. I would instead receive texts from others in the conversation. I could freely text any of the same individuals in a separate standard SMS conversation just fine, and they could send me an MMS text like a photo, but as soon as we were in group MMS I'd lose the ability to receive their texts and no amount of APN changes or combinations of texting apps would fix it.
I can't tell you how many times over the course of the first 5 months of owning my Pixel XL with an AT&T SIM in it I missed out on half the conversation in group MMS. Doing nothing to my phone other than porting number to T-Mobile and putting in my new T-Mobile SIM all of my group MMS issues went away (replaced with ****ty signal LOL but that's a different story). I'm now on Verizon with my XL and am a happy camper, albeit poorer having wasted money jumping around.
