XZ1C - wifi calling VoLTE on Metro PCS - Sony Xperia XZ1 Compact Questions & Answers

So I cant get wifi calling or volte to work on metro pcs.
BUT
I popped in a deactivated project fi sim and it reconfigured for wificalling volte. I then restarted with the metro pcs card and I had wifi calling for about 5 seconds before the phone said configuring for your network and rebooted.
Anyone have any idea? It seems the XZ1c is seeing the metro card and turning off that stuff. It doesn't seem to have anything to do with weather it will actually work or not.
It's just not just not working, the xz1c takes away all the features *#*#4636#*#* has volte and wificalling grey and non switchable. With the project fi sim those are turned on.
Maybe i should just switch to t-mobile...

I use "Ting", an MVNO that uses T-Mobile for their towers (like MetroPCS I think?) and I got WiFi calling working through this guide:
https://www.reddit.com/r/SonyXperia/comments/7dlwe7/xz1_compact_fingerprint_scanner_volte_wifi/
The gist is you use UK firmware but replace the UK's OEM.sin file with the US OEM.sin file.

Did wifi calling not work before you reflashed ? Also has anyone tried this on the newest update?

Any progress on this? I'm in the exact same boat with Metro PCS - would love to get wifi calling and/or VoLTE working on my xz1 compact but don't want to go flashing roms until I know it'll remedy the issue.

I have the xz1, after flashing the compact's OEM.sin I tried to get volte, needless to say with my metropcs sim it didn't work. So I grabbed an old straight talk(t mobile carrier) sim and even though the sim isn't active the volte option was there and then I grabbed another working t mobile mvno which when put in the phone worked great HD calling while staying on LTE. So in conclusion it is a metropcs sim problem and I am not sure what if anything can be done about it. I know the sim can do volte, before I bought my xz1 I had an LG k20, and my wife had an LG G5 both of those volte worked perfectly.

The basics of it though are this, if you don't have an E911 address in metro system you put on in and then change the apn

EE UK Wifi Calling

Hi folks, I'm having a bit of difficulty or confusion with wifi calling. I'm on EE but my phone is an XEU. There was a wifi calling option that didn't seem to do anything; no icon when enabled and no obvious network connection.
So I switched to the EVR firmware, wiped the phone and set up from scratch. Still got the same wifi calling option, still no icon or network activity with it enabled.
I don't seem to have VoLTE either, I would have thought the EVR CSC would enable that too?
Does anyone have any insight on this?
Thanks.
I have been having weird issues too with a dual SIM version and EE Wi-Fi calling. Inserting a microSD card in second slot can sometimes disable Wi-Fi calling in that I don't even see the option for switching on.
Hopefully future firmware fixes these glitches as I'm really loving this phone after using iPhones for a few years .
Jake
Wifi calling and VoLTE enabled itself after a serendipitous restart today.
Did your wifi calling ever actually work without an EVR CSC or firmware @ajdjackson ?
Edit: Looks like EE had some stuff to set up on my account, problem was at their end. My account says they're setting up roaming and could take up to 24hrs so something has happened to instigate these changes.
Anyway, now I'm really wondering if I need to EVR firmware at all. Samsung's multi CSC system should allow EE's wifi calling but EE would insist that it doesn't. Can anyone chime in?
Yes - strangely mine seems to working OK now even with the sd card in second sim slot. I haven't flashed any firmware at all.
Jake
Right, after a switch back to XEU I can confirm that EE Wifi Calling does work on a non EE phone but VoLTE does not!
So I switched back to EVR and everything's working fine again.
Quite surprising since EE have always insisted that Wifi Calling is exclusive to phones supplied by them, yet I've never read the same about VoLTE.
Hiya,
Just thought I'd share my experiences...
Like you, I'm also on EE and again like you my NOTE 8 is an XEU SIM free model, in my case from CPW. I found the same issue in that the wifi calling option could toggle on and off but the setting didn't seem to do anything; no icon when enabled and no obvious network connection.
I phoned EE on 150 for support but all they could suggest was to reboot my router at home even though I told them I also have a "work's" mobile phone (iPhone 5c) also on EE and that combination does have working wifi calling.
I decided to try a test to determine if the issue was with my Note 8 handset or with my new EE 4G SIM by swapping SIM's between the two phones. The work SIM worked immediately by activating wifi calling in my Note 8. My personal SIM was active in my works iPhone for approx. 2-3 minutes with no signal before a pop-up message appeared asking if I wanted to activate wifi calling. I obviously selected 'Yes' and when I swapped the SIM's back to their original handsets my Note 8 now magically works with wifi calling with the original SIM.
It's almost as if the menu item in the Note 8 for toggling wifi calling on and off doesn't activate the sim card even though the graphic animates to show the function activated.
Anyways, I now have a Note 8 with working wifi calling.
Hope that helps anyone else with similar issues involving EE wifi calling.
*EDIT* Hehe looks like my signature is a little out of date.

Thanks Steve. Do you have VoLTE? I can't get that working without swapping the firmware for the EVR specific one.

Hmm I don't know. I know that I have 'Mobile Networks' setting 'Network mode' set to 'LTE/3G/2G (auto connect)' as opposed to the other settings of '3G/2G (auto connect)', '3G only' or '2G only' but how can you tell if a voice call is routed over 4G? Does a special icon appear as in the case of wifi calling? Hard for me to say as I have zero signal at home and very poor signal at work so in both cases my Note 8 defaults to wifi calling.
Have you tried calling EE to check if VoLTE is only supported on branded firmware as opposed to generic XEU? I know that in the case of wifi calling their website is very explicit in stating that wifi calling is not only supported on EE branded/sourced handsets but also works on certain generic handsets such as S8 / S8+ & Note 8. Their website on VoLTE or as EE term the service '4G calling' is not so clear...

This EE Community Forum post seems to lay the blame at Samsung's door as opposed to EE's...
https://community.ee.co.uk/t5/4G-and-mobile-data/VoLTE-on-Samsung-Galaxy-S8/td-p/559521
Reading the thread fully, it seems VoLTE is only available on EVR and not XEU.

Yes, this shows the VoLTE icon which appears whenever I have no wifi or I disable wifi calling.

The discussion on EE you linked is interesting, so they do limit VoLTE to their own supplied phones. I'd recommend switching to an EVR firmware, despite the guy who says there's no advantage for the user, I've found VoLTE very useful, especially in conjunction with Wifi calling. VoLTE/Wifi calls are so much clearer, they can seamlessly switch if you lose the wifi signal and they seem to connect a bit quicker too.

Ahh there is a symbol, thanks for sharing the picture. I can confirm that do not get VoLTE and whilst it would be good to have every function that I pay for working the fact that I get zero 4G signal at home and at work where I spend 90% of my time means I'm not realistically going to miss VoLTE as my phone now has a working 'wifi calling' service. I suppose that if EE ever get round to providing coverage in the blackspot that surrounds my home location then I might consider swapping to EVR firmware. I won't hold my breath though because in the 20 years that I have lived at my current address, EE and Orange before them haven't bothered with trying to provide adequate cellular coverage.
I remember going through exactly the same crap with my Samsung Galaxy S2, Orange firmware got an app called signal boost and the vanilla xeu firmware didn't and we had to do a number of things to get the app ported over to XEU. Seems like no matter how much technology advances over the years some issues never change.:silly:

Tips for Getting Functional Wifi Calling on AT&T.

Since there have been a few posts about people wanting to get their non-AT&T S9 working on AT&T with all the advanced features, I figured I'd post some tips since I have 2 S9s that have been successfully converted.
1. You must come from a U1 firmware to the AT&T U Firmware.
2. Make sure your Sim Card is fairly new. I have had sim cards work in an older phone but not a newer one.
3. Have AT&T hard set the IMEI of a AT&T branded phone(that supports wifi calling). Do this by putting your sim card into the AT&T branded phone and call AT&T customer service and say your Wifi calling and HD Voice are not working.
4. Make sure Wifi Calling was active on the AT&T branded phone before moving the sim card to the S9.
Also make sure you have ATT csc installed. There are a few required apks that are in the odm folder. I was able to get it working on a SM-G965F
I wonder what else could be tried?
I have done all of the above coming off a brand new unlocked U1, flashed the U FirmWare with ATT User data file. I can actually setup WiFi calling on the new handset (it doesn't really work ,however) and about 10 minutes later I get a provisioning failed message.

Funny you should ask this. Up until last night I could swap the SIM into the old phone and WIFi calling would provision and work. I tried this morning and the old phone is now giving me the same "ooops... we cannot provision..." message. I was thinking bad SIM card again? It's 10 days old though.
EDIT: Chatted ATT and verified they have the old IMEI set from the old phone that had working wifi calling.

I will be at work tomorrow which is located near the ATT store also and at work I have access to a fiber fed service with WiFi for "Non Work" use that is great and I will try that. I have Gigabit CATV internet at home wired thru a Ubiquiti Router and POE Switch and using a MU-MIMO (UAP HD Nano) access point which gives me a 433mbps wifi link to my S9. At home, I also have a 1st GEN At&t Micro-cell which I have left unplugged in case that could be an issue.
If WIfi calling doesn't activate on the work wi-fi then I will grab another SIM card at the at&t store and try again.

Sounds like a plan. I wish I knew why wifi calling is such a pain, I could never get it to provision on my old AT&T uverse internet. I ended up provisioning my Dad's Galaxy S9 wifi calling via the hotspot my S9. If anyone you know would be able to hotspot their At&t phone that might let you provision wifi calling.
1. ATT must have a Samsung Branded ATT Phone's IMEI in the system, so that the features are allowed on your phone.
2. If you have U1, you need to use the U CSC, the U1 CSC breaks wifi calling and all other features that AT&T gives you.
3. If you are able to get root, and can see the system apps,
Under App Folder you need to have
UnifiedWFC
Vsimservice
Under Priv-App You Need to have
NSDSWebApp
WfcServiceV2
3. When you are trying to enable Wifi Calling Service, what happens when you click the wifi calling quick toggle.

Could not provision on my work wifi or my AT&T iPad hot spot wifi.
I went to the AT&T store and got another new SIM card. I then chatted 5 or 6 AT&T Cust Svc. agents and got one that re-provisioned the IMS features and set my IMEI from the S7. They now work on my ATT branded S7, but not on the unlocked S9.
Within 3 second of toggling the WIFI calling feature I get the "ooooops we cant turn on wifi calling, please have an authorized person call.........."
I flashed the HOME CSC when coming from U1 to U. Can I just flash the U CSC as is, or would it be better to flash back to u1 and then back to U with the proper CSC.?
It would appear I had several obstacles to getting this enabled.

LOL Failed again!!!
Flashed U firmware and ATT User Data file. Nothing works. Same message.
What is "...Also make sure you have ATT csc installed......?" I have not been able to find any FW that is AT&T for the U. Every other carrier, yes. but no AT&T.
SO I have flashed back and forth a few times this evening. I did not locate a specific "ATT" CSC file. I did find the ATT USerData file that places the WiFi calling option in the menu like always. So it looks like you can use IMS features on ATT as long as you have the ATT U Version or a Carrier U version variant.
However, If you have the U1 version then it is not possible to use these IMS features on ATT.
I think you can just flash straight to U make sure your sim card is in the phone. If it doesn't work, try factory reset and then flash U CSC
I forget are you able to root to see what system files you have?
You could probably update the phone to the newest U1 buold, but switch out the csc with the U.

All U CSC's include att CSC.
Not rooted yet. Looking forward to it. I'm on U FW now. I couldn't get the IMS features working but I strongly suspect its AT&T. If AT&T
Disabled and enables my IMS on their end then my S7 wifi
Calling works. So into my S9 the SIM goes, it allows me
To check my 911 address and begins to provision but usually
Fails within 10 minutes.
Then, from there on I get the standard "Oops we cant provision" error message on subsequent attempts. Which requires lengthy calls to ATT to disable & enable IMS again. This makes me believe that my S9 IMEI is getting checked and flagged, then IMS is disabled.
Out of the blue I got a forced ATT OTA update today that updated my FW to ARBI, now I see another pending software update waiting. For the new boot loader I assume.
I did try my MINT Mobile SIM and even on the ATT FW I got the IMS features to work, and toggle in the "secret" device info.
I thought I'd give it a go w/o rooting.
My auto-update OFF was overridden and I got pushed the G960USQS2ARF4 to my handset last night.......
US OR US1? Well you can flash the arf4 U CSC right?
So they have you with an ATT S7 ? PM me or telegram me at @Psyscope I'll give you an imei for s8 that will make sure you should have wifi calling provisioned for your account.
These three apps are needed do you have them when you go to Apps?

Sounds like you are running the latest AT&T firmware. If you put your sim into the S7 and call AT&T Customer service and report that Wifi calling isn't working(make sure they hard set the IMEI of the S7 to your account), then re-activate wifi calling on your S7 and then move your sim card into the S9, and try to activate wifi calling.

Could one of you kind folks upload the above mentioned files from an S9 device for me .......... I am experimenting with an S9 port on my S7 Edge and can get WiFi Calling to provision but it still doesn't seem to work on the Phone app itself.
I get all of the activation responses and can even modify my Emergency Location dialog etc. , but no work with WiFi only or poor cellular area.
My CSC Flash and device doesn't have WFCServiceV2 ( just WFCService) and I don't have UnifiedWFC in the app folder
I can get WiFi Calling on Nougat and finally today on Oreo --- but I'd really like to run the Sac23 Port --- it seems the smoothest

Question --- This is kinda what I've done in the past to get calling features on ATT but I do it by going to my AT&T Business portal (I'm a business customer) and changing the IMEI there. That has worked for me in the past by using an IMEI from a branded store model phone - lol
But I have had some issues ---- when the IMEI that I put in the billing portal doesn't match my actual phone that I'm using then When I go to Phone > Settings > More Settings > Call Forwarding I often get errors or can't set the provisional forwarding numbers (I used Youmail for Voicemail in the past and currently I have been (when Busy, Unreachable , or Unanswered) forwarding to my Google Voice phone number that now has a Google Voice over WiFi Beta program. The other issue is that setting the IMEI to another number messes up Call Forwarding with things like Samsung Gear (AT&T numberSync) ???
What exactly did you get the AT&T Customer Support to do when you called ? maybe its different than what I'm doing in my Business Portal
A different imei has no effect on forwarding, that's related to your sim card. The IMEi if it is an AT&T branded one you call them and tell then to update it to one that's linked to an att branded Samsung phone that is wifi calling capable.
In regards to the s7 edge you would need to extract the csc files from an odin. Then find a custom rom and move the files around. Are you using the an unlocked S7 edge u or F? Because ttkg has a CSC selector.

You know call forwarding rarely works that way. There is the feature
Where you manually setup forwarding.
Dial **21*, followed by the 10-digit number you wish to forward the calls to, then dial #. For example, **21*1235556789# forwards your call to 123.555.6789.

Mi 9 cant activate with LTE on AT&T network?

So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.

I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?

So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?

For those who use Verizon MVNO's VoLTE Now works after Update!

I have a Verizon S9 with flashed T-Mobile firmware from back when I had it on Metro, which has the Verizon bloat from inserting a Verizon sim, anyway I use RedPocket CDMA Verizon on this phone now, and apparenlty VoLTE was broken last year after an update and there was work arounds like enabling emergancy mode and swaping the sim and it would stay until reboot.
Well Glad to say the new July update, it now has VoLTE!! There is now an option under Mobile Networks for VoLTE. And it works!
One strange thing though now instead of it showing Verizon, as the network it shows "Roaming Indicator off" which its not roaming. But just glad to VoLTE now works!
Another note: This T-Mobile update doesnt show avalible yet online? but yet it updated.
I wonder if there a way I can get where you are. I have a tmoble s8+ and put a verizon sim in to switch it to verizon and then switched that for my red pocket sim and VOLTE option shows in the menu but when I go to the *#*#4636#*#* menu also available through forceLTE app I see VOLTE but its grayed out. Also just as weird is that wifi calling is switched on and I cant turn it off. DO you have wifi calling on and which firmware are you on? I am on security patch level april 1st 2019.. Maybe I need to get your update and that will do it, but I show no update available.

You might have to manually flash the update. But the April patch doesn’t have it for the S9 anyway.
I don’t think redpocket does WiFi calling volte setting is under mobile networks

Is your software ver PPR1.180610.011.g955USQU5DSD3?
Yeah red pocket does not support wifi calling or video calling that is why I cant figure out why that is turned on on my phone. I just want VOLTE to work. I have it in the network settings menu just not on the field test mode 4636 menu and when I make a call no VOLTE.
I might just start from scratch with oden and download the latest verizon image. My CSC says VZN/VZN/TMB. Is that what yours says? granted I know your on an s9 but the s8 and s9 and even the 10 are really similar with there software packages.

YeAH i Know the guys on telegram say most of the stuff works the same between the 3 phones with only minor differences..
This has to be what your talking about.. https://9to5google.com/2019/07/25/g...ng-out-w-july-security-patch-qr-code-scanner/
Here is the reason I believe Im not seeing the update.. https://thedroidguy.com/2019/06/wha...-plus-wont-install-downloaded-updates-1081849
Son of a... awesome.. Ok so I re-enabled auto pre-config.. See here: https://forum.xda-developers.com/ve...0v-success-t3558214/post79937998#post79937998
THen I put in a tomble sim and got the update for july. Im downloading it now. I thought that disabling auto pre-config would be a good idea but I relaized the verizon is so anal that they would not allow me to get the update because my phone is really a tmoble branded. Anyway tmoble will give me the update then I can auto preconfig back to verizon and be using VOLTE... THANK YOU for your topic.. finally got it..
---------- Post added at 10:23 PM ---------- Previous post was at 09:56 PM ----------
Unfortunately I'm not getting as lucky as you are. I cant get on VOLTE, I cant even get on CDMA now with my red pocket sim. Ill keep working on it and see if anything else needs to be done, maybe a reset. I got cdma and i think ill have to disable auto pre config.
I wanted to post another update to those who are using an MVNO verizon or possibly other carriers, for s8-s10. I was finally able to get VOLTE to work but you must flash the matching carrier firmware, auto pre config will not work when using an MVNO. I Flashed the verizon firmware for my tmobile S8 and got the verizon modem file which I think made the difference. My CSC changes to vzn/xaa/tmb. Use odin and flash the CSC or CSC home and everything else in the other fields minus userdata. CSC will erase userdata, csc home will not.

Glad you got it! On my s9 as long as auto config switched it was fine. Even worked on T-Mobile firmware for volte before the auto config

VoLTE on At&t

So I spent an extensive amount of time about this whole VoLTE situation with this phone with both At&t and ASUS. My question is how do you know if you are actually utilizing the VoLTE connection?
I am able to make clear voice calls while browsing the internet or downloading an application. My speeds vary anywhere between 60 and 100 Mbps with no connectivity issues. The phone has no indicator of LTE connection but is constantly 4g++. Asus and at&t both stated that is the LTE connection. So I went into the phone settings via the image in this and it shows the VoLTE setting not toggled.
So the next question is, what indicator is there that this connection is NOT VoLTE other than this toggle? The speeds appear faster than Hspa+ but nobody I spoke to had the technological knowledge to be able to explain this. Also what speeds down and up is everyone else receiving?
From what I have read, this phone doesnt support VoLTE. And what worries me is that all the carriers are transitioning to VoLTE starting in 2020. Some are saying phone calls will no longer be possible on this phone. Which confuses me as it just released.
You can tell by making a voice call and seeing if the phone stays on 4G++ or drops to 2G/3G. I am 99% sure we will not get VoLTE on this phone. TMobile rep suggested tweeting TMobile on Twitter as the marketing team there might help, but I just don't care anymore. I'll stick with my pixel 2 xl for now.
Is ANOTHER thread on this necessary? Wtf? No volte. Not now, not ever. Get your money back. Asus are idiots for releasing this phone in us with no volte. 2020, no phone calls. Enjoy!

I know VoLTE is 100% possible on this phone, however not in the USA. It has something to do with the USA companies and At&t told me VoLTE is definitely a possibility as well as WiFi calling in the future but that has to be certified by the US companies. This phone supposedly works with WiFi calling as well as VoLTE in the European market as they don't have the same issues with the companies controlling the way it operates. I am moving to Norway on the 23rd but honestly the connection has been fantastic and I do like the phone quite a bit. During my phone calls I remained at 4g+ or ++ while surfing the web or watching Netflix with no issues during the call or the film itself.
I have messed around with it to see if there was anything that seemed off about it but so far it has worked just as well as My note 10+. Also the phone is operating on 4g so saying that it can't be used is silly. The 4g band will be around for quite some time while some companies like Verizon are removing 3g as it operates on the cdma versus gsm. At&t will continue 3g operations until 2022 and 4g will take years to completely phase out from 5g and by then another phone will replace the ROG 2.
I will however annotate how this phone operates on the European networks once I arrive. As per my previous post I can obtain 40mbps up to 100mbps which is definitely 4g speeds. 3g can not obtain those types of speeds. The bands available are key to the operating network for sure though. I think at&t seems to offer the best fit here in the USA.

I am currently using this phone with AT&T. So should I be good for calls through 2020 and 2021? Reason I ask is because I literally just got it a week ago, and then read this news about the whole VoLTE thing and was just devastated thinking I have to now find a way to sell it and find a new phone.
Also, since I got the phone, I am only ever on H+ for the signal. I thought it was LTE capable? I came over from Verizon, so the H+ was something new to me. I know I am in a LTE area. Do I need to do something to activate it?

Was this a ported number? When I went from Verizon to at&t there was an issue when I ported the same number back to at&t. They were able to get it resolved by calling Verizon having them refresh the port and then re initiating the LTE from their end. And that was with my Samsung. I did speak to at&t again today about the LTE and they may have to make sure your Sim is "LTE" and also making sure they unlock it on their end. Supposedly the LTE and volte have to be activated from them. Also ensure you have the appropriate APN setting as sometimes with unlocked phones those setting do not carry over.
And the phone should be working fine until a minimum of 2022 even with 3g or H

I did bring the number over from Verizon. I may have to go in to AT&T to resolve that from what you're saying then.
Dealing with the APN setting, I am good with tech, but this part has me a tad confused. What should I be looking for on the phone? I see under APN, it says AT&T is selected. There are other options like tracfone, but I assume its fine then if it has AT&T selected?

Here is what at&t recommends for APN settings

And yes something about how Verizon and at&t handle it some things can get "hung up" in the system

I tried those APN settings and it seems to not work. The signal bar still shows a signal, but there is no longer a H or H+ sign. Hmmm

That's interesting, but I would recommend going to at&t and confirming that LTE is good to go on your phone. They can also verify nothing is stuck in the system and your appropriate APN settings
