Hey guys!
Is it possible to get VoLTE on Dev edition M9?
If it supports 4g then yes but if the other person you're calling doesnt have 4g for whatever reason then you wont be making a volte call to them.

Here in India, there's this carrier called Jio in which you can make calls only if your phone has VoLTE, but the stock dev edition M9 doesn't have VoLTE, so I wanted to know how to get VoLTE.
Thanks for replying.
Im quite sure the m9 does support it so long as the carrier supports it. As I said, both phones, both carriers, both must have a good 4g signal. If you are both on Jio, both have a good 4G signal then you should have volte. If they are on a different carrier then there could be a cross network issue at the carrier end. Maybe a call to your carrier could answer in more detail?.
The m9 is clearly marked as volte capable on various sources and the wiki page here: https://en.m.wikipedia.org/wiki/Voice_over_LTE but searches also indicate that it may be dependent on what the carrier has enabled at their end.

This has been my experience. On both T-Mobile and AT&T, with the developer edition SKU RUU installed, VoLTE has not been enabled. I'm fairly convinced it's because there is some carrier setup that doesn't support it.
It may be different if you have your carrier's SKU RUU installed, but I can't confirm that - just a theory.

The M9 doesn't really have VoLTE, only a few versions of it do (such as the T-Mobile version).
Also, from using it on my other phone (a S7 Edge), it doesn't matter if the other person has VoLTE too, it'll still be able to make a call, just not a HD call.

That's because the Dev edition doesn't support VoLTE. You could check this thread out for more info.
It kinda sucks that hardware wise it does support it but not from a software view.
I want to use VOLTE in korea, So I have to know my htc 10(unlocked ver) support TTA VOLTE CODE.
Does HTC 10 support TTA VOLTE??
TTA VOLTE is code which makes VOLTE available.

You need your firmware and your carrier to support it. Unlocked model of HTC 10 supports VoLTE. If your carrier does then you are good to go.

I already know unlocked htc 10 support after nougat. But I searched , To use VoLTE in korea I need some code(or type) in firmware.
My carrier (Sk telecom) doesn't support international VoLTE code(type). They use their code not international code.(I don't know exactly).
International VoLTE include all VoLTE types? If yes, then I can use VoLTE.!

If your carrier doesn't support VoLTE, then you won't be able to get it. I'm on Telus in Canada with a US Unlocked device. US Unlocked supports VoLTE, but my carrier only supports it for the newer iPhone models. So I don't get it and you won't either, unless I/you change carriers or our carriers decide to support it. Sorry, but that's the way it is.
EDIT: I misread your post. And don't understand it to tell the truth. VoLTE should either be supported or not. If they don't use International/WWE code (?) then try US Unlocked firmware instead.

As someone who lives currently in Korea and understands this issue on a very real level (lolㅠㅠ),
most carriers in the world use a VoLTE standard defined by the 3GPP. What Google claims regarding baking VoLTE into Marshmallow is according to the 3GPP standard. This is why I can buy a phone in Spain and take it to Germany and use it no problem (for the most part).
But Korean carriers established their own VoLTE standard called TTA-VoLTE before 3GPP could create an international standard. So any phones bought in Korea likely won't work with VoLTE abroad, and vice-versa (save for some exceptions).
In terms of carrier, the key exception is LG U+; since their network depends exclusively on LTE and CDMA, for BYOD customers (해외구매폰) they have to support the 3GPP standard on top of the TTA-VoLTE standard (see link below). There are some success stories of people taking their Hong Kong phones and using it on LG U+, their LatAm Samsung phones, etc.
In terms of phones, iPhones and some Google phones, some Sony phones (flashed with Korean ROMs), and some LG phones supposedly support TTA-VoLTE (check 2nd link).
My advice? If you have the phone with you, either take it to LG U+, see if they can register the phone as "OM-Phone" (Open Model), and see if VoLTE works; or just live without VoLTE as I have been doing for the past 2 years (ㅠㅠ).

Before i explain what i/we all hope to achieve, ive been increasingly worried about network shutdowns. Ive seen at&t shut their 2G network down, I believe verizon is next with sprint or t-mobile to follow. For those who dont know without VoLTE, us verizon users use 1xRTT which is 2G voice. So, if verizon shuts the 2G network down, what do we do? So now that that speech is over.
Ive seen threads around on other phones and somehow the devs for these phones got VoLTE working on united states carriers. i dont know very much but i hope we all can use this thread to gather info and come up with ideas to get it working. I do know that the stock software has some sort of "sign" that in some way shape or form verifies the phone in some way.
The unlocked one supports many 4G VoLTE bands. If you want to know your carrier supports or not, ask your carrier customer support for VoLTE bands and cross check with below link.

Useful info, but I believe our main issue with custom roms is some sort of signature that tells the carrier something, thats about all I know
I'm curious as to what doesn't work when you purchase an unlocked version vs Tmobile branded? Im told you may have issues with wifi calling/rcs/video calling/and visual voice mail....
2. How easy would it be once you get the unlocked version to flash the carrier software to make everything work and then flash back to original if needed to be for resale or warranty
The reason im asking is that samsung is giving a bigger refund on the unlocked version...

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

Note 9 was able to do this and I did it. I don't see a reason why you shouldn't be able o do it in Note 10+ once carrier firmware become available to be downloaded.
I pre-ordered the unlocked version myself and I have AT&T so it should be as easy as waiting for the carrier firmwares to become available on SamMobile and flashing with Odin. My interest is now with DeX supported with microsoft if Odin is even neccessary to flash firmwares anymore?
from what i can see on sprint i think they are using the qualcomm chip, i could be wrong, its labeled as SDM 855 Octa-Core SDR8150 and when searching that in google qualcomm documentation on the 855 pops up
Very curious about this myself. I preordered the unlocked version because that gave me more value for my trade in. I'm curious if I get the unlocked version and flash TMobile carrier software. Will I then get tmobile updates ota?
It's been the same for years now, hardware wise phones are the same, you'll need princey odin to flash unlocked/carrier firmwares. I buy unlocked and flash the carrier unlocked firmware. No bloat but it has the carrier specific radio. I prefer the native caller Id, no bloat, and the RTT over the carrier bloat and video calling. Google duo is better anyway

Are you TMO or ATT? I have accounts with both.
I know WiFi Calling, which is what I really need as far as carrier goes, is usually more difficult with ATT.
If you are TMO can you get WFC to work without flashing carrier?
How long do you usually have to wait for the carrier firmware to come out?

Wifi calling has no issues on unlocked firmware with tmo. At&t I'm not sure but if you flash the att csc and and cp files, I do believe that's all it takes. I believe you need to flash the at&T AP file.
My Note 9 is unlocked. Using on T-MOBILE with no issues with WiFi calling. I am not able to use the stock visual voicemail though which I would prefer. With T-MOBILE I'm forced to use their visual voicemail which really sucks. Does anyone else know if they're is a way to use the stock visual voicemail on T-Mobile?

When I inserted my SIM it appeared to automatically install the T-Mo firmware, but that's the problem.; it forces me to use the T-Mo VM (which absolutely sucks) and not able to use the Samsung VM which is pretty nice. I had previously used the Note 9 on Verizon with my work SIM and I was able to use the stock VM. When I switched to T-Mo it forced me to use the T-Mo VM. I can't see a way to get back to the stock VM unless I'm missing something...

I go into the phone app call or SIM settings and find the call forwarding settings:
Then I do they conditional forwarding to my Google Voice number (I then, after setting up Google Voice, turn on Do Not Disturb for Google Voice, so I don't get there phone ringing twice)
Then GV serves as my VM

^^ What he said. Do not make the mistakes I, and many others made in the past - do NOT buy a US version from T-Mo, or from Samsung USA website, unlocked or otherwise. All USA versions are snapdragon based, and will have permanently locked bootloader - no rom flashing of any kind, no custom recoveries or improved radios. What you need is SM-N975F/DS Exynos version (unless you use CDMA carrier like Verizon or Sprint). It will have the same bands supported as Snapdragon one, with the exception of band 71, which you dont really need. T-Mo's B12 serves the same function as B71 (extended range LTE), and T-Mo made the tech available only in limited number of cities anyway. In all likelihood, by the time they roll it out in your city - you're gonna be thinking about buying Note 12 or 13.
Don't worry about software features like voice calling or any other - with all the custom roms and development available for Exynos version you'll be able to find yourself a rom that has any features you like and then some.

This is great advice ..... IF ..... you are looking to root and/ or do custom ROMs. But having done every release S9+/Note9/S10+ with Exynos it's NOT always that easy to get the CSC stuff right and working (and the development is often done by people who could care less about NA CSC because they don't live there).
Root / Unlocked bootloader = the Exynos device, like you said.
So what appears to be the answer (for the thread, assuming no root) after looking at all the answers in this and a couple of other threads is that the Unlocked US Samsung device is the same (or can, in worst case scenario, by Odin flashing carrier firmware, be made to do) device functionally as the carrier devices --- calling features, etc.
For me, the difference was going to be $300 bigger discount.

That's only true if you want to unlock the bootloader and root. The OP was merely asking about flashing carrier firmware on the US Unlocked version, which does not require root or an unlocked bootloader.

the bigger trade in value was a deciding factor as well for me...Well we weill see how it goes on the 23rd
I want to be able to root and flash TWRP on my Note 10+, but when i did this on my Note 8 i bought the N950N which was the korean exynos version and CRC support for t-mobile sucked ass, i want to make sure
A) what model do i buy for
- Rooting and stuff
- and best t-mobile network compatibility without going through all the dumb stuff

Same here. When Samsung stopped hobbling the OS, and added more features I didn't need root anymore. The extra $300 was my deciding factor. I have the unlocked Note 9. The only thing I have noticed aside from slower updates is that the camera sound can't be turned off independent of the global phone sound. Everything else works fine and I haven't noticed anything useful missing.

I was actually giving advice to all folk, considering purchasing, not just the OP....Also, just curious - how do you Samsung's locked bootloader on the unlocked Note (I hope you know 'unlocked' means SIM unlocked only) will accept firmware, signed by T-Mobile? It's not a given Samsung original bootloader, untainted by carrier branded modifications, accepts carrier signed ROMs. You may need to be using T-Mobile version of the bootloader, for it to accept T-Mobile signed images.
Does the U1 (or U) unlocked US version of s21 fe support volte in India on Jio network? As far as I can tell, it has the required bands (B3, B5, and B40) that Jio uses, but I found that many claimed it doesn't work on older devices like the S8. I know that S8 works on airtel in India becuase thats what my dad uses but Airtel calling works without VoLTE. Please help me out since I need a new phone urgently. The phone will be used in the US for atleast a couple weeks so the region lock should not be a problem.
Any help is appreciated.
@AyushDhoot please update here mate. Did you get the phone? Is VoLTE working? I'm planning the same so would appreciate your reply.

Hey, I went ahead and got the s22+ instead. I'm still in the US so I'll update once I get back home in a couple weeks.
