I bought a refurbished LG G3 D851 T-Mobile from eBay. The phone is GSM and Unlocked, as the seller mentioned.
I tried to switch to 3G network mode, but couldn't. If I select WCDMA Only in network settings then I find no network signal at all. In our country we only have 3G connectivity and that's the only choice we have.
What should I do to get 3G connectivity? Any help?
Android version: 5.0.1
Build number: LRX21Y
Software version: D85120e
Kernel version 3.4.0
Try and call customer Support..........
Not like that...

Thanks for your kind information. But living in another country using other network I can't just call T-Mobile customer support for help. I thought of flashing my LG G3 D851 ROM to D855 European general version ROM--so that I can active 3G connectivity. I want to know the process.

Hardware inside (radio, bluetooth, WiFi) are different. 855 firmware or rom will not work.

Thank you for your reply. Then how can I activate 3G in my smartphone?
Try Advance Signal Status app in the Play Store. If you are rooted, the advanced screen lets you change signal options.
Hi,
I just got a sim that only supports LTE and VoLTE for calls and messages and basically any connectivity. So what I am looking for is a way to add VoLTE support to my LG G3 D855 32GB International Unlocked phone. It can be a stock ROM addition or a custom ROM, which supports it. Internet data connectivity works fine, just for the VoLTE part I have to use a custom app, which calls over the internet through LTE, but I'd like to have the VoLTE functionality integrated in the ROM. If someone has a solution then it'd be greatly appreciated.
Thanks!
First of all check if your phone is capable of VoLTE.. Most of snapdragon and Mtk phones are capable of it.. Second if it is capable then change modem/baseband as per the requirements of service provider. And some minor build.prop addition.. Then you may use Volte. Anyhow cm13 can be made volte capable..
Hi guys,
I just wonder if M9 supports VoLTE calling. My carrier told me that HTC M9 will never support this function because I have to have stock rom literally from my Vodafone Czech carrier. But it seems to me that in that case nobody with alternative roms could use this function so my question is..does it support VoLTE if I will root my device and install some patch what I've seen here for volte support or do I have to install another Rom which supports VoLTE or any other ideas? Does my carrier have to really support precisely my model or is it just software issue on my side? I have newest Android 7 stock. Thanks for all replies!
Yes, the M9 absolutely supports VoLTE. Disclaimer: I have one on the desk next to me fully operational on a large carrier in the USA.
Given that, your network and your device work in unison to make the 'magic' work. You'll need an IMS APN programmed in the device, and one in the LTE network that validates the new default (signalling) bearer. My suggestion is to chat with a knowledgeable tech support rep. at your carrier, and be sure to ask if there's extra charge for the VoLTE. Since carriers understand that legacy circuit switched infrastructure has a limited future, they *should* be willing to move all your voice/SMS/MMS over to the IMS/LTE network they've invested in.
Best of luck.

Thanks for detail info. VoLTE is new in our country so I couldn't get any tech info even from my carrier. And I already found out that VoLTE isn't extra charged and even video calls are for the same price so that's great but I have to find precise info about IME apn setting. I hope somebody tell me precise settings. Thanks for info again!
Volte is carrier dependent. Both phones must be capable, both carriers must be capable. The problem is that Volte is not cross carrier at the moment so you and the person you're calling must both be on the SAME carrier, the carrier must be Volte capable, both with Volte compatible phones, both in a 4g signal area.
4g is a data only protocol with voice capabilities "patched" in to it. 4g was NEVER designed to carry voice signals so don't expect carriers to be in a hurry to implement Volte when 5g is just around the corner.
As to the answer to your question. Yes, The m9 is in fact Volte capable so it is purely down to the carrier investing in new technology. Carriers are NOT obliged to roll out Volte in any case. It is purely a case of demand vs supply. We already have a perfectly good 2g-3g infrastructure for voice and data so 4g only offers better data connections depending on signal strength. I think a lot of carriers are going to hold back for a while until the technology becomes proven or more so, an ISO standard is put in place.

Thanks for answer. My carrier already support VoLTE technology and we also have around 95% coverage of LTE infrastructure and I know both must have VoLTE support and LTE connection.
What I am trying to is use this technology if I am able to. My carrier told me it's not possible because my phone is old for it but I've read few articles that it's possible.
What I don't know if I need some option in settings (rom implemented settings) to activate it because I don't have any inside, on the other side when I go to cellular info through *#*#4636#*#* I have info about IMS and also about VoLTE what I can switch off.
So generally is it enough to find out how to setup IMS APN in settings to run VoLTE on my device or do I need also ROM which have implemented in settings VoLTE on/off?
Maybe I just don't get it correctly but I would like to have precise info what I need to get from my carrier to set up IMS APN on my device to run VoLTE if it's possible of course.
Hope it is understandable.
So no need to any special futures implemented in Android. It's enough to set up APN for IMS and LTE bearer.
The only device that needs adjusting for volte is the dev edition, i believe.
Otherwise this device is completely volte compatible. Maybe your carrier representative is confused..

So I finally talked with someone who knows more technical info from my carrier but he told me that it's all about radio bearers, channels of phone (don't know precise terminology) and my phone has to be unlocked for that channel, so it's kind of firmware problem because in our country isn't firmware unlocked for that channels yet. And nobody knows if it will be. Also each carrier has different channel for that and that's why it's incompatible with the same phone from another carrier.
I've seen also some utility to change that radio settings over PC with debugging mode on but don't know more info about it. So I guess I can try this for a last option.
If your phone is locked to carrier and branded then there is a possibility they've switched volte off but if your firmware region is 401 then your carrier rep is talking s**t as all 401 wwe (unbranded) phones are volte ready and it is the carrier who is lacking the technology.

Thank you, I don't have for now rooted M9, because I bough it recently and until now I tried to find out all option if it's possible in some way but I'll do it and try it later. Thank you very much for your help!
So I've tried and it doesn't work, no VoLTE , no Wi-Fi calling, so I am not sure what could be wrong. I can see setup in system and it's enabled but none of this works. Is there any log or anything what I can explore why it's not working? My carrier has a app for Wi-Fi calling so I wouldn't need it as a part of system but there could be setup which I need also for VoLTE if I get it right. Or is there any other flashable file for trying?

VoLte And Video Call in Verizon M9
Hi Guys,
i have tried t-mobile rom for volte it worked great. also i notices that if i am changing firmware , volte is not working , as the volte options are still showned, when i get back to t-mobile firmware its worked. so i also searched that t-mobile rom has integrated IR92 lte support for volte, RCS integration and many things. Were i found that Verizon version has Integrated IR94 lte support for voice and video call over lte.
So Can any one help me further for this.

I have an AT&T running latest firmware unlocked rooted s-off the whole nine yards and my VoLTE will not work I can go into *#*#4636#*#* and turn on the provisions for it but when I exit it turns back off I guess I'm going to have to go back stock cause this sux I bet I've missed 15 calls today!
Is or has anyone else been able to get VoLTE working on T-Mobile US on this model specifically? LTE and WiFi Calling work in general, but the "Enhanced 4G LTE Mode" toggle isn't there to allow VoLTE. The model has the same number of bands as the XT1710-01 model, but is on the RETLA channel, by the way.
Hi, actually I was having similar issues. VoLTE, seems to be different but is based on your Carrier mostly. If you call someone from a different carrier it may not be enabled. I'm with AT&T, whenever I call someone with AT&T and we are both with good 4g LTE, in the call, changes the status to HD. But, just with AT&T. At least that's how it Works for me. We should wait someone to confirm is this is how other carries behave.

Apologies for the late reply. Definitely no VoLTE or HD voice between me and other T-Mobile users. No matter what I tried it just never came up. If anyone's considering using this specific variant of the phone in the US, I'd be aware of the limits beforehand.

-06 is a North American dual sim variant, correct. Updates should go through ATT Mex, I believe. And yes, you can use sims from other carriers. I used one sim card when I tried it and only utilized one of the sim slots as a result. T-Mo VoLTE just doesn't seem to have been certified for that variant.
So T-Mobile WIFI calling works on this variant of the Z2 Play? If so that is good to know especially when traveling overseas even if some other advanced features don't work.
I have an XT1710-06 retla device and I can confirm that wifi calling with T-mobile does *NOT* work on my device. There is a setting to enable wifi calling, but it never seems to connect and all calls still go over mobile. This is 100% testable if I for instance go into a deep basement that has wifi but no cellular signal -- I can browse the internet but cannot make phone calls or SMS, even though I have wifi calling turned on.
This is probably related to why VoLTE doesn't work either.
Also (as mentioned in another thread) still no updates for it past February 7.1.1 update. No later security updates and no Oreo updates.

Hi,
I'm super curious how did you get your Z2 Play to have VoLTE. I 've tried everything - new sim, IMEI of ATT branded phone, activated SIM on ATT phone, etc. , to no avail. I'm so frustrated and about to get another phone, because my HSPA signal is much weaker than LTE where I'm at and constantly have missed (straight to voicemail) or dropped calls. Please, let me know how did you get it to work.
Thanks
Maybe the problem is VolTE itself. As I tested. Unless both phones are with the same carrier and working good over 4G (good signal area) you can't get it working. At least in where I live that was true for a friend's phone and mine. So VolTE was good, until signal dropped hard. But impossible to work with other carriers.
Even it was good under Lineage OS and tested with Toxyc OS, but I saw the main thing is that 4G LTE should be firstly working fine. And same for anyone you call. Otherwise call will be normal. And for 4G LTE it depends on area support too.
Sorry for late reply

Same phone (XT1710-06 retla, rooted stock ROM on Oreo), and wifi calling on Tmobile also doesn't work for me. I can enable it in Settings, but I cannot send SMS or make calls over wifi with no cell service. After a while (a few hours) I get a Moto Settings notification that it can't enable Wifi calling, with a message underneath that says "Enabling." I can't dismiss the notification, only snooze it for up to 2 hours, and after I disable wifi calling it does eventually go away after a couple days.
Your problem is because none of the XT1710 variations have the 600MHz Band 71. It is the most recently added band and very few phones currently out there support it yet. As far as the HD voice issues mentioned...both people on the call have to be using a Volte supported phone and then HD automatically activates.
I have purchased LG G7+ thinq Indian variant recently. I am facing issue with VoLTE for Airtel network. I am getting 4G but not volte. I didn't find any settings to enable it also. Can some one with Indian variant help me on VoLTE issue.
Reading the forum here I have tried flashing Singapore firmware but that didn't help...
Have the same problem here in mumbai.. airtel works only with 4g not volte.. whereas Jio volte works well.
Same case here..in India only JIO is supported..no other networks VOLTE is supported by this Flagship mobile of LG.
Somebody from India needs to call up their software update centre to develop and release updates for India as well....all most other regions have got at least the Sept updates.
Who knows..might be also possible that LG might soon exit from their Smart phone business in India like they had in China earlier this year..given it's dismal market share...if that's the case..no more updates..

Volte is licens based. Your operator have to pay for the licens to get it Working on every model.
So. Maby your operator havent bougt the licens for lg g7.
