UMA on G1?

I've been looking for a straight answer on this and I can't seem to find one.
I know the G1 doesnt have UMA on it fresh out the box but heres my questions.
1) Is UMA hardware enable or software? In other words do we need the hardware on the phone (thus making it impossible) or is it software?
2) If it is software then are any developers able to enable?
I've searched many forums and have yet to find a concrete answer. Even the mods on T-mobile forums arent sure.

From my understanding, UMA is a hardware dependant so there will be no way to get the G1 to utilize UMA.

It from what I understand hardware., phone like the Dash and the shadow have wifi can't do it with a. Software update. Tmo had to put out a new shadow 2009 to give it the UMA capabilty. I did read somewhere that magic/g2 when going through FCC approval was approved for UMA which there was no mention off with the g1 so we might have to waiut and get the g2 to get UMA

wifi chip on the g1 supports uma so its just a matter of software...

Wrong, it does not support UMA. The G1 never had nor will it ever have UMA. Maybe in the future on a totally different device there might be.

UMA is software and it should be coming to us sooner or later:

UMA is not SIP (which is what the link in that thread refers to). Both are VOIP but they are very different in implementation. UMA basically pushes your standard GSM traffic over an 802.11 connection to a specialized router that connects directly to T-Mobile's backbone.
So while SIP is basically a computational exercise UMA is more a rerouting of existing signalling to a different radio. At a guess, and I stress guess, it is a hardware thing at the radio level. It might be able to be added at the radio firmware level, but I am still just guessing.
This is sort of off topic but I was wondering... What is the benefit in UMA that makes it important to people? I can understand the appeal in (effectively) a femtocell so that you get coverage where signal quality is poor but other than what are the value adds? (I am on the $50 unlimited plan so minutes do not cost me anything) I wonder if I were to take a UMA cell to Europe and hooked it up somewhere with a low latency pipe if I could effectively be "local" to my U.S. T-Mobile carrier... Latency might be an issue, I am not sure since I have never used UMA.

why do u say that? this is the wifi chip (wl1251) that the g1 has and the chip clearly is able to do uma.

There are 2 versions of that chip on the TI site and according to http://www.phonewreck.com/wiki/index.php?title=T-Mobile_G1 it uses WL1251B which could be a variation of that chip without uma. It depends on what the carrier ordered from HTC. Regardless of what chip the G1 has it doesn't support UMA. You would need drivers to support UMA and I doubt any exist at all. It may eventually support VOIP through Skype but it all depends on your carrier.

[Q] Nexus One & Developer Phone

As my trusty ATT N1 soldiers on, I'm considering whether to jump to a new carrier in the near future so that I can stay current with upcoming Google Developer Phones. I would appreciate some feedback regarding the assumption that since the G1, Sapphire, and N1 were TMobile compliant, we can expect that the next Google Dev Phone might be exclusively flavored TMobile. Do you agree?
Thanks all.

We can assume sense they had a close relationship with Danger and now Google that they will stick with the same bands for Developer Phones. Just like we can only assume Google will stick with HTC for official Developer Phone hardware.
Again, this is only based on the past.

well history is all we have to go on.
one of the main reasons why T-mobile 3G bands have been used on the dev phones so far is because its the most compatible worldwide (ie works with the most carriers in the world, you can use them in the US, Canada and in Europe)
considering this its pretty likely to continue to stay this way. ATT 3G band is no where near as widely used and CDMA phones must be carrier specific (well they don't have to be really hardware wise but the way they work vs GSM phones its extremely dependant on the provider allowing you to use a phone that is not theirs on their network, it can be done but its a real pain to get them to do it)

Wifi calling and voLTE on Att only

Wanted to ask if anyone with a USA model rog 2 tried att Sim card and did it work with att? We already know t-mobile doesn't list those options. This way we can all go search for phones that will suit our needs.

My US model will be delivered either Saturday or Monday and I use AT&T. Will post my results then.

I just talked to support again, and they said no VoLTE or VoWifi on Tmobile, Verizon, or AT&T, or any American carrier. They have no plans to enable it. The suggestion was that I leave them a complaint, so I did so via their form on Asus.com as well as Facebook.

The problem is AT&T is shutting down their 3G service this year so if VoLTE isn't enabled we can't make voice calls.

As is TMobile, from what I understand. You should be able to make calls, but it will default to EDGE, IIRC.

Ok I just tried to confirm and got info they're not shutting down 3G just yet. We still have a few more years.
I guess that's good we'll still have calls but isn't good because there's no reason for VoLTE.

Thanks to ryououki for the offer, we will await your testing and we will be here if u need any help

I seriously don't understand a U.S model, yet no volte? That's just dumb. Wtf?

I can tell you right now it wont work, Its a sick phone but I'm sending it back because of this. Asus screwed up with no VoLTE, no VoWiFi, and only a 1080p screen IMO. Maybe next time they will get it right. I hope the OnePlus 7T and the 7T Pro has it... Crazy!

Just read this for T-Mobile:
Due to lack of VoLTE support you won't be able to place and receive calls including 911 calls in some buildings and some outdoor areas where 2G GSM and 3G HSPA+ signal (marketed by T-Mobile as "4G") is too weak or non-existent while LTE band 12 is available

Great info so far , just need someone to try it with att sim for confirmation.
So far we know,
Tmobile no go on volte or wifi call
Verizon works on data only no calls or txt just like rog one. Cdmaless option unclear at this moment .
Att no test yet

I have a US model on AT&T and can't get VoLTE yet.
I talked to AT&T support and they said there's no compatibility yet.
The IMEI doesn't come up in their system as a known device.

I have at&t and a USA version of the phone, I can confirm as well that the phone drops to 3g when making voice calls.
This is really really bad because at&t plans to shut down their 3g in 2021, that means no voice calls after that. Asus USA knowingly selling a $900 phone that cant make a call in 2 years is borderline fraudulent.

There has to be options somewhere we can atleast get VOLTE working. Yes root will be mandatory, but i am ok with that. I might order one from amazon. Whats the return policy for phones on amazon? Anyone know?

I believe there were reports that VoLTE was working on Tencent models?
We really need to look into making a custom rom for our phones for the US carriers.

Did you try dialer codes *#*#VOWIFI#*#* and *#*#VOLTE#*#*

How ridiculous. This is how you ruin a near perfect phone.

I did more research, it seems to be more on the AT&T side than on the Asus side of things. Barring a few well-know phones like the Pixel 3, most BYOD Android devices on AT&T in general don't get VoLTE, including unlocked versions of Samsung Galaxy devices that are not purchased through AT&T. It looks like AT&T does not enable VoLTE for device models with IMEIs that it does not recognize (i.e. doesn't have AT&T certified ROMs), because they are afraid of getting fined by FCC for non-E911 compliance which requires the carrier to certify E911 support on all handset/firmware when on VoLTE. My guess the Tencent models with VoLTE working are somehow whitelisted by AT&T ad-hoc or they are working on Non-U.S. carriers. So it is more of an AT&T problem than an Asus/ROM issue. (though there may be ROM hacks to ask the handset to force VoLTE even if AT&T doesn't advertise the capability during protocol handshake).
Since this is a much bigger issue than just the ROG II phone, hopefully they have a plan to white list all BYOD Android devices for VoLTE when they sunset 3G. Otherwise AT&T would stand to lose a good chunk of revenue from those who migrate over from other carriers with BYOD phones, say a Galaxy phone with a T-Mobile ROM. You simply can't even offer a BYOD plan if you don't have voice call working for most of the BYOD Android devices.

I'm pretty sure their return policy for phones is the same as all other goods. I bought and returned the original ROG phone last year through Amazon, considering doing the same with ROG II unless there's a breakthrough on providers and features with custom ROMS/etc.

Yea that's pretty dirty to whitelist the Tencent version but not the US model.

Contacting ASUS regarding the VoLTE issue

Hello,
I have been emailing, messaging, and calling ASUS regarding this issue. Today, I spoke with a supervisor over the phone regarding my work ticket for VoLTE.
His words not mine, ASUS is not currently attempting to get VoLTE functioning on this phone in the US. No future plans are being made for this. He was unable to give him specifics regarding a memorandum ASUS put out regarding concern over connectivity in the US, but stated that they (ASUS) are aware of the issue and will not be seeking further solutions.
I did my best to express how Verizon 3G doesnt function, ATT 3G will shortly stop working, and that TMobile is only offering a brief window before their 3G shutdown. I further explained that TMobile 3G is really only good for a small percentage of the US and that the vast majority of US cities will not be able to properly utilize it for voice calling. We went further into details on how those 3 companies are the only options in the US as smaller companies just "rent and borrow" tower bandwidth.
With all this said, it appears they are very aware that this phone will not have functional voice calling in the US very soon and for whatever reason, are unable or unwilling to fix it.

This is essentially the same response I received when I contacted them. In my communications, they seemed to blame the North American carriers for the issue since VoLTE works in other countries.
Admittedly I know very little about Band X 123 but Asus's argument is a good point from my laymen's perspective. When I pushed on T-Mobile, they informed me they do not disable features that it's the vendors control (this was my take-away from the FaceBook chat I had with a T-Mobile agent). So now I don't know who to believe.
At this point, I'd just like to know why a particular feature (not necessarily VoLTE) is disabled/enabled to begin with. Is it politics, money, something else?

It's not TMobile, it's Asus. Volte works on redmagic 3, all xiaomi phones have volte too. Asus are a bunch of dbags. Don't buy the phone.

Considering buying the phone, I have a couple questions.

This phone sounds amazing, but theres some conflicting information i've heard on it from multiple different sources.
1. Does the phone work on verizon? My current phone plan is on verizon, and it would be so much easier to just change out phones rather than move my entire wireless company to get this phone. I've heard that it does and it doesn't. Is it the chinese versions that don't? I'm american, so do the versions sold in America work with verizon? I went to my local verizon store, and they said it wouldn't, but the lady had to look it up on her phone but the article she saw might have been talking about the tencent version or something.
2. If it doesn't work on verizon, what other network would work better? I've heard that T-Mobile wouldn't work well for this phone, so maybe AT&T? Again, I would greatly prefer to just stick with Verizon.
PLEASE PLEASE PLEASE answer my questions, I've asked these questions in multiple places but no one has answered a reliable answer in any of them.

No on Verizon. Yes to tmobile and att. Chinese and international versions have different lte band support. Talk to your local tmobile and att reps to see which bands you need and verify on the Asus site for rog phone 2.

A few users here say they got it working on Verizon as a data only device, and it does support their LTE bands. For calls, they mostly use Google Voice but one buys a cheap subscription on an AT&T MVNO for calls.
It doesn't have band 71 support for TMO, which could make coverage an issue. AT&T has the best support from what I've seen.
Something else to note is this is not VoLTE certified in the U.S. It can only make calls on the GSM networks, and those will be shutting over the next few years. If you plan to keep the phone long term, expect to lose the ability to make any phone calls. You could move to Google Voice at that point, but you'd still be left with no 911 access. Asus has so far indicated they have no plans to certify it for VoLTE in the U.S. (even other region versions that do have VoLTE wouldn't be able to use it here).

I'm not exactly the best at phone lingo, i just stumbled across this website while looking up things about the phone.
That being said, can you tell me whether or not the phone is worth it? It seems like theres wayy too many disadvantages to this phone, and that kinda bugs me. I've been wanting this phone for a while, so I'd much rather get this than anything else.
If it's not really worth it, can you mention any other phones that are similar? mainly one that can emulate games just as good if not better than the ROG 2?

"Is it worth it?"
That is such a loaded question if you're in the U.S. That's something you'll have to decide for yourself based on your needs. If it had VoLTE here, then it would be worth every penny. All I can say is that for me, it isn't worth it. Yes, you get a ton of value for the phone. I'm on Verizon and would've been ok switching calls and texts to Google Voice. I also planned to keep it long term, likely after the GSM network shutdowns. I also drive for a living, hauling hazardous materials. So in my case, the inability to make a 911 call once those networks shut down is a very big concern. For me, that one reason alone is why I've decided to hold off on it.
On the flip side, if you don't have a problem with the 911 issue, or plan to switch phones in a year or two anyway, then this may very well be worth it in your case.
As for other options, I think the Nubia Red Magic 3s is likely the closest in terms of features and performance. It's not quite as bleeding edge as the ROG 2, but it's also a lot cheaper and has VoLTE calling. The Razer Phone 2 is another known option, but it's a generation older too and support may be questionable (rumor has it there may not be a Razer 3). I don't know a ton about either phone other than what I've read on their specs.
