[ASUS ROG Phone II Questions & Answers] Mr_Mooncatt:
Same here.

I'm not very familiar with GV, but I thought it made calls via the data network (hence why it works on Verizon). But it still leaves the problem of 911 calling, or lack thereof. I talked to someone at the FCC, who said they are getting a lot of similar calls. She said the 3G networks are supposed to remain online for 911 access, but the AT&T rep says otherwise. Any attempt at tracking down official documentation either way has been like finding a needle in a haystack, and all the haystacks Google gives me haven't had the needle. It's all results about calling 911 from non-activated phones in general.
[ASUS ROG Phone II Questions & Answers] suzook:
Got a link??
[ASUS ROG Phone II Questions & Answers] ExecutionerDan:
So from what I've gathered from this thread is that the rog phone 2 does have voLte. Due to this, it can't use 4g calling, instead using 2g and 3g calling, but phone carriers are shutting down 2g and 3g for regular calls. What the actual F U W K is going on here? A brand new phone that costs 900 USD that I can't use by 2020? Excuse me? I didn't even hear about this issue until I started reading reviews on Amazon cause I was literally in the middle of purchasing it. Will there be any way at all to call people using a 3rd party app? I really want the rog phone 2, and I know it is unacceptable to not have a working phone call, but if I can get a phone app that'll work I'll have a miniscule chance of buying the phone. What is this about Google voice?
[ASUS ROG Phone II Questions & Answers] Mr_Mooncatt:
Google Voice works similar to Skype, allowing you to make a voice call as a data transmission instead of traditional voice networks. Because it's seen as a regular data stream by your carrier, it works on the 4G LTE network like anything else. The down side is you won't get to make 911 calls and requires a bit of setup.
[ASUS ROG Phone II Questions & Answers] ExecutionerDan:
I saw this post on this website called 91mobiles on how to enable voLte on Asus rog phone 2.

I can't post a link since I just joined xda and they so t let new people post outside links, but it shouldn't be that hard to find.

I know that the chances of this working are a 10,000,000,000% of failure but it doesn't hurt to try. I just want to have a beastly phone instead of a glorified mini tablet. I don't own an rog phone 2, but can you guys tell me if the video helped? There was also an app he showed that can hopefully do something.

This link? https://www.91mobiles.com/questions/how-to-enable-volte-on-asus-rog-phone-2

If you read the comments for the video on YouTube, it’s a hit or miss if it works or not. Personally I think the video title is click bait.
[ASUS ROG Phone II Questions & Answers] Epiksol:
Unnecessary snarky comments aside, I'd like to update that I have received a full refund ($962.99) with no mention of a restocking fee.
[ASUS ROG Phone II Questions & Answers] ExecutionerDan:
I can't even quote you with that link but that is indeed the link. I didn't check the comment section on YouTube because I swear I think I'm braindead sometimes. I just saw the video and thought "eh screw it, it's worth discussing on xda. Doubt anything will happen but I can't say I didn't try." When will Tmobile and at&t be getting rid of their 2g and 3g connections though? If it's in 2 or 3 years then I'll maybe consider buying the phone, but I heard somewhere that it'll be by January 2020 that voLte will be a mustneed if you want to call people. Maybe ill just wait for the rog phone 3 I guess. Its only like 10 months away or something like that. Hopefully Asus get their F U W K I N G S H I T together by then.

Hey. I did a quick search and saw this guy on reddit had the same results on TMo

https://www.reddit.com/r/zenfone6/comments/ctkdjr/lineage_os_16/

What do you think?
[ASUS ROG Phone II Questions & Answers] ExecutionerDan:
That's actually really helpful I think. I have no clue how to actually make custom roms or do what you guys are doing, but from my point of view it looks like all that guy would have to do is put the rog theme over that for when you turn on the phone, add the rog gaming hub, and blamo it's done. Or maybe even just do the same stuff he did on the zenphone to the rog phone now. Why don't you try getting in contact with him and ask for help? I would ask, but I don't know the first thing to discuss beyond enable voLte on rog phone 2, and also I don't want to make a Reddit account just for this.

Lol, yea, simple as that. Uhm, not.
[ASUS ROG Phone II Questions & Answers] Goronok:
5 pages of pointless banter because someone spreads misinformation. AT&T is not and cannot turn down any 3G radios before 2022.

T-mobile does not have FCC approval to drop legacy voice support yet, but has been trying to get approval for awhile. Folks here should be wary.
[ASUS ROG Phone II Questions & Answers] waynewarrior78:
IF you read their own QA page about it, they are clear at some point they are stopping the activation of non VoLTE phones. This is before 2022. they aren't going to just flip a switch either. They are slowly cutting 3G bandwidth and coverage during the next 2 years to make way for 5G and more 4G LTE. If you want to buy a $900 phone that doesn't support basic functions such as VoLTE that's fine, I feel people should be aware of what is happening.

Edited to add: look at TMobile 3G vs 4G LTE coverage, it's horrible. Band 12, 66, 71 don't have corresponding 2G and 3G, thus situations arise where you have full data but no phone or text.
[ASUS ROG Phone II Questions & Answers] SavageCat-TX:
I didn't want to create an account either but finding some pretty interesting stuff on Reddit. LOL

So for the hell of it...I downloaded the lineage rom for zen6...I extracted the system.img and fastboot flashed it. I expected it not to boot, but holy sht, it booted. LMFAO. Unfortunately still no VOLTE
[ASUS ROG Phone II Questions & Answers] stealthj:
You have tmo or ATT?

What about Wifi Calling?

I believe in you! I'm pretty surprised it booted.. is that all you flashed?
[ASUS ROG Phone II Questions & Answers] suzook:
Tmo
[ASUS ROG Phone II Questions & Answers] cheetah2k:
So looks like I've gotta run a 2nd sim card to get Volte?

I found this under my SIM1 options after the 1908.25 update and a full reset last night. Before the reset this was not available...

Any of you guys have this option??
[ASUS ROG Phone II Questions & Answers] Neet:
What networks are your sim registered to?
[ASUS ROG Phone II Questions & Answers] cheetah2k:
Vodafone in Australia

I've got a data sharing SIM that my kids use in their tablets, ill try that tonight to see if it works :good:
[ASUS ROG Phone II Questions & Answers] suzook:
Your right it's a new option, but your sort of reading into it wrong. It's not going to enable volte....it's just an option if you already have volte.
[ASUS ROG Phone II Questions & Answers] cheetah2k:
We shall see when i add the 2nd SIM :good:
[ASUS ROG Phone II Questions & Answers] SavageCat-TX:
It's been long enough... spill it! And what did we see? :fingers-crossed:
[ASUS ROG Phone II Questions & Answers] suzook:
It's not gonna work. It only works if volte is working.
[ASUS ROG Phone II Questions & Answers] suzook:
Doing some research, maybe no volte isnt the end of the world.....

4G (HSPA+)

Frequencies that can provide 4G: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)

4G offers incredibly fast download speeds, nearly as fast as 4G LTE. See Data speeds.

Voice and data services can work at the same time. You can use data while on a call

This is on Tmo site....My calls drop to HSPA+, so technically if Tmo turns off 3g.....I am ASSUMING they will leave on HSPA+, which means as long as band 2 and 4 are available, we still will have calls working. Not ideal, but not the end of the world.
[ASUS ROG Phone II Questions & Answers] SavageCat-TX:
The thread of the title really needs to be updated to "Attempting to Enable VoLTE in North America".

VoLTE is available in other countries, just not in North America.
[ASUS ROG Phone II Questions & Answers] Mr_Mooncatt:
Agreed. Lol
[ASUS ROG Phone II Questions & Answers] SavageCat-TX:
Suzook mentioned early on in this thread that the issue is probably with the modem files. After reading blog, I would agree. https://www.manipalprolearn.com/blog/18-steps-turn-volte-android-phone (step 16). The article is well written and the dude sounds like he knows his poop here. I wonder if Asus would actually produce phones with different modems or if it really is just a driver issue. Model numbers should clear that up though, right? If so, then it should just be a matter of having the phone initialize the modem drivers on bootup and of course the actual modem files (modem drivers) available on the phone. It seems to me the modem files should be able to be extracted/copied from any ROGP2 in the world other than USA and added to the custom rom(?).

I may not be using the terms correctly (still learning this poop) but this is the gist of the issue/resolution in pseudo coding terms.

Spit-balling ideas here hoping something will stick.

What file(s) are needed for the boot sequence? How could I review the files? Assuming I can find the string that needs to be modified, would the file need to be compiled or is it a text file? I'm sure there is a general thread on this I'd be happy to review, just not sure what search terms to use. If someone has a link or search terms to try, I'll take a look.

Let's drop the name calling and complaining about the thread, especially since the name calling and complaining comments far out number the comments they're aimed at.

The very first sentence in the OP says this is for the OPs International device, so multiple comments suggesting the title should be changed to USA or North America only further clutter the thread.

Rather than complaining, tossing insults and name calling, how about those tired of the craziness, or frustrated with the thread, just move on? Comments that violate the rules will be deleted, and accounts that continue to violate the rules will be reviewed for restriction or removal.

If someone posts something that you feel MIGHT be a violation of Forum Rules, please simply REPORT that post. Nothing is more ridiculous than 10 posts complaining about how ridiculous 1 comment is.

Lastly, as courtesy warning, please keep all comments respectful and helpful, if your comment isn't either of these, just don't post it. Move on.

My lack of knowledge here is about to show but stiffens said he is working and is rooted. You are rooted and isn't working... sounds like a match. I have "Beyond Compare" that I can use to compare text-based files to see what the differences are between two sets of files/directories.

Or are you saying we need a dev who would understand what variables would need to be changed and comparing the two phones isn't enough? Is stiffins not really working?

Yes, WiFi-calling is enabled

Weird how hard it is for Asus to add just some codes to make VoLTE and VoWiFi work.. ?

The issue is USA....it will work everywhere else.
[ASUS ROG Phone II Questions & Answers] ddragonfly:
I'm planning to buy this phone but I'm currently in the UK so I cannot test it for America once I received the device. I'm not an expert onn moderms but I had looked at the previous solutions briefly to enable VOLTE/VOWIFI for the Oneplus 7 Pro (as it has the same chipset) and for the ASUS ZENFONE MAX PRO M2. By comparing the two solutions, it could be possible you are missing the IMS configuration file or the drivers to enable VoLTE in the US:

No, not without beeing rooted and add the lines of code that is needed for it to work.. (Very hard for Asus to do I guess) Maybe your carrier does not support it? Have you tried to add the code to the build.prop file manually, and not with terminal?
[ASUS ROG Phone II Questions & Answers] suzook:
Yes
[ASUS ROG Phone II Questions & Answers] stiffis:

YEs....its more of an issue with VOLTE in the USA
[ASUS ROG Phone II Questions & Answers] stiffis:
Hmm, to bad ? hope you guys figure it out asap
[ASUS ROG Phone II Questions & Answers] ddragonfly:
I think if you don't know why VoLTE is not enabled in the US without a clear explanation from the technicians in ASUS then you might to have to test it systematically to isolate the issue and try to work the reason why VoLTE is working in the rest of the world and not in the US. Prehaps you can try and get some help from the devs at Zenfone 6(2019) to figure out why it is not working in the US and how they managed to enable VoLTE for the US carrriers.
[ASUS ROG Phone II Questions & Answers] suzook:
They only got it working on Lineage, not stock os. Which would be fine with me, but i dont know how to build a rom.
[ASUS ROG Phone II Questions & Answers] ddragonfly:
Actually HSPA+ is part of the 3G network, it's also known as 3G+ or H+ in other countries. In the UK, it's usually displayed as H+ on my phone's notification bar. The mobile network operators can repuropse the 3G bands to 4G /4G LTE but it's on a different techonology. It's very likely they might shut down HSPA+ alongside with 3G, You have to check with your mobile network to confirm this.

Not in USA .. I'm ROG 2 user from Malaysia have a same issue.. my Telco only use 4G cannot make call and sms.. now I can only use internet data from this phone..this phone very useless without Volte access..very2 disappointed..
[ASUS ROG Phone II Questions & Answers] jkeener88:
I never had Volte, even on my previous phones, so I don't know what is so great/important about it, but what I do know, is that I use my phone extensively and have 0 issues in Houston, Texas USA and many surrounding areas on the same sim card I had from my Samsung Galaxy S8. So yeah, just throwing that out there.
[ASUS ROG Phone II Questions & Answers] mhnizam24:
No issue without Volte if your Telco support 2G and 3G..my Telco only support 4G no 2G or 3G.. without Volte I cannot make call.. for gamer if you received call without Volte you got lagging because you line drop to 3G when call in..

Its a long shot, but does T-Mobile authenticate IMS via IMEI?

If thats the case maybe doing a sktechy IMEI swap with a valid T-Mobile phone would allow for VoLTE?

No they don't....any phone volte capable works on tmo. It's Asus that disabled it.
[ASUS ROG Phone II Questions & Answers] MyronAz:
What possible reason could they have to do that?

:confused:

EDIT: I am not meaning to imply that they didn't, just wondering what possible reason they could have had. It seems very odd.

Is it possible they need to pay someone a royalty to enable VOLTE? Maybe they are waiting for a patent to expire?
[ASUS ROG Phone II Questions & Answers] SavageCat-TX:
It’s seems the phone manufacturers have to pay the telco to have their phone or the features of a phone “certified”. Asus didn’t so the telco won’t allow them to enable it. This is my understanding only - I’m not quoting anyone here so I may be wrong.

I’m not sure why other phones such as the Red Magic 3 is able to have it enabled and at a such a lower price point so it doesn’t quite seem like the decision is financially driven. It almost feels like asus pissed off the telcos and this is the backlash from it. Again not quoting anyone here, just my opinions only.
[ASUS ROG Phone II Questions & Answers] suzook:
It's just Asus being cheap fcks.
[ASUS ROG Phone II Questions & Answers] stealthj:
I think it has to do with FCC E911 certification or something like that.

I still believe we'll get VoLTE working once we know how the zenfone guys did it

[Touch Dual, MDA Touch Plus ROM Development] Blob8me:
Hi. Hoping someone can help me out here - I seem to have "Fried" my mini-usb port on my Touch Dual? :(

I had connected my Dual to my Vista PC in order to flash the latest Mary Rom - it started to charge the battery but hadn't picked up the device in Windows Mobile Device Manager (as happens some times?) - when I started the CustomRUU I of course got a connection error and this is when the port seems to have "died"???

The Dual now no longer charges - either from the main power supply or from PC or Laptop and I get the error message "USB Device has exceeded the power limits of its USB port" when I plug it into an XP Laptop?

I'm hoping that this is not a permanent "hardware" issue and that someone has had the same problem before and has a solution?

I have tried: Soft Reset, Hard Reset, Removing the battery, Changing the battery, changing the software settings for the usb port?

Help.....?????
[Touch Dual, MDA Touch Plus ROM Development] Blob8me:
So its been a few months now since my Dual died - I've just found it in the bottom of a drawer in my office and its reminded me to take a look and see if anyone else has had this problem so I thought I'd refresh the thread....

Any (ANY) advice would be great - I cant return it to HTC as its stuck with a custom ROM loaded and I cant connect the USB (obviously) to change it back to a shipped rom......

Is there any way to flash an original rom from a memory card? :confused:

[Touch Dual, MDA Touch Plus ROM Development] mjbozzy:
I am new here, but i am an electronics technician who has had a similar problem with my NEON 200. Seems that PC USB Ports can only supply 5VDC @ 500mA max and the NEON power pack is 5VDC @ 1A. I continually charged off my PC and Laptop when i could not find my mains pack - i think this eventually killed my phone or battery as now it just does not charge and i cannot turn on the radios. I did however measure the volts on the battery to be correct, and i did briefly get the device operational again (without the battery warning then turning itself off) for long enough to get a new ROM on the phone hoping this would fix it. FAIL! I have the same problem again... I hear there is a fuse on these that could be open cct, so i am going to look into that now. Hope some of this helps.

BTW - i hard reset the thing about 50 times (hoping the vibrate on start up would run the battery out) and this is how i got the thing working again the first time (before the ROM update).
