volte and T-Mobile? - Samsung Galaxy S8+ Questions & Answers

anyone use this and have seen volte working? Made a few calls on mine today and the phone always drops down to 4g only.
I have put my sim card in my pixel xl and every call goes over lte.
I have also tried resetting network defaults and resetting apns and that didn't help. And all the data works perfectly fine on lte for me still though.
Any ideas?

I have the Verizon 8+ and I'm using a TMO sim as well. Mine drops to 4g too. I don't know why nor how to fix it, as all major carriers are "u" models.
*edit
I'm starting to think it's software specific because I don't have any option to video chat. It only comes up when I insert the Verizon sim in it.

Interesting. I have a button for video calling but it just fails. Does volte with if you put the Verizon sim card in?

Verizon card brings up video chat. With the TMO one in it disappears.
Side note...
I'm curious to know if i flash the TMO tar will it fix the volte and video chat issue

It doesn't surprise me that VoLTE won't work on a Verizon model, since it doesn't have the T-Mobile software. VoLTE works just fine on my T-Mobile branded S8.

I have the Verizon model and my VoLTE is working perfectly fine. Maybe if OP tries selecting HD Voice Only as opposed to HD Voice and Video Calling under Advanced Calling settings.

I have T-Mobile S8 and it does not have ant VoLTE settings. Also Video call S8->S7 does not work

Wonder if there is something goofy with the software going on.
Just downloaded the firmware from updato and looking to see if I can flash with odin.
It seems like the package is not a standard tar file I can flash all at once but seperate files like I saw with the s7.
There is also a userdata_tmb in there as well. Not sure exactly how to flash that though.
Is there any guides on exactly how to flash it yet that I might not be able to find?
Only seen basic ones that say about flashing a single file which don't really match up to what I see here.
Waiting now to see what the download from SamFirmware has as well. Need to wait about 4 hours so I will need to look at it tomorrow though.

Yeah I can't find a setting for calls with volte. I need to turn it off. Calls have always sucked for me with it on. People always tell me in breaking up whenever I have it on.

I am having the same exact issue and it's very frustrating.

In Poland it works great. VoLTE and VoWifi too but before it works I had to activate this option via sms on T-Mobile.

Didn't touch any of the settings.

Did you do that urgent DQA update Samsung pushed out yesterday? I'm thinking maybe that changed something for me?

Verizon SGS3 no 4g... bug

so on verizon I got my sgs3 and activated successfully ..... so I thought. didnt notice 4g at any time, so called in to verizon and said that I have read a few posts of people not able to activate properly and I think my 4g is missing.
tier 2 rep didnt have the phone to look at and after an hour said it might be a bug, like one that was with the razor maxx. so I get to wait till today for a call back and them to tell me they dont know why Im in a 4g coverage area but not getting 4g....
fun times verizon thanks because being on the "better' network makes it all worth it.
I had to restart my phone after a while then 4g showed up.
I have the same issue. Activated 2 SG3's yesterday. Both are only showing 3G connection. I live in Tyler TX and I know we have 4G coverage. I talked to a rep yesterday and they pretty much told me the same thing. She said maybe there is an update coming to fix it.
They also had me pull the battery and reseat the sim card. Still no 4G

Same here, I'm getting spotty 4 g at best and the signal is **** when I do. My tbolt would have-79 at my house, my Sg3 gets -112 at its best. Just spoke to second level support and was asked to take the SIM out for a few minutes and try again. Same results as before. Here is a pic off my current status. Oh yeah- 32gb pebble blue here.

losing root was my first thought when rep mentioned the update. but in the end, one of the phones hugest points is 4g. Without that i can use another phone.
I have no issue with 4G, and haven't. I am also rooted and have been since it was announced.

I'm not sure what to say really. It could be everything from service problems, to the phone having issues, to Verizon working on the network... I mean, had you had a 4G device prior you could compare with?

[Q] LTE on Straight Talk?

Upon using my Straight Talk Nexus 5 with an AT&T sim, I noticed the data connection displayed LTE, which I've never seen before on Straight Talk. Is anybody else noticing this change? As far as I can tell on their website they still only support up to 3G speeds...I'm using the tfdata APN.
Here's pictures of LTE in the status bar as well as my speed test with two/four bars:

Is this a new thing or does anybody know what's up?
EDIT: after looking further into it I saw people have been getting LTE on the Nexus 5 with Straight Talk since the 15th of November withe new AT&T sim card and tfdata APN settings. I'm still curious however as to why LTE is just kicking in now instead of a month ago when I got the phone, with the same setup.
It's been a few months they started offering Lte service

ST has been supporting AT&T LTE since release of their "new" SIM cards which use the tfdata APN. Not knowing where you live, I suspect AT&T just rolled it out in your area.
Are you using the ST recommended APN settings, or have you modified them slightly as some websites recommend?
This.... The main reason I moved from Note to Nexus 5. Very quick. The other change they made recently is to be more clear on data usage. I think it explicitly states 2.5 GB now before throttling. Be careful with that LTE!

I'm using the recommended APN settings from apn.straighttalkbyop.com, for zip code 53095, although now I am curious of what changes are recommended, and their benefits?

[Q] Oneplus dropping from mobile network

So my oneplus one occasionally drops from the mobile network. It happens almost daily and it just says no internet connection, no signal bars, no LTE/H+/anything. Only fix is to reboot wich is annoying. Has anyone reported this. Have unlocked and rooted with super-su, no modifications. I wiped cache and dalvic cache with no help. Used the phone few days and it's a constant problem.
I read about one guy with the same problem. He couldn't find a solution though.
Very helpful post..
I have the same problem but no solution yet. dbm values get very high 22453576 sth like that. You tried a different modem?

Lose the attitude. Maybe there is no fix for it, he was letting you know that. You should be thanking him for taking time out of his day to try to help you. How ungrateful and rude could you be?!

Try another sim card. While unlikely, it's still possible it causes the issue.

If there is no fix, that means one thing: RMA.

Had similar Problems (With my international OPO)
Flash this radio! It worked for me
I have the same problem and I think it's my sim card.
Had the same problem with my HTC One, and now with OPO.
It's the same sim card so it could be what's causing it.
Not a SIM issue (I think)

I was lucky enough to be able to buy 2 1+1s. My wife has an older SIM with no LTE support - great signal.
Mine has LTE, but like above, shows very high # signal in status screen, but signal goes from high to low to no signal. I tried wife's SIM, full signal all the time.
I'm in Canada on Fido (Rogers). Great LTE speeds when it works tho.
I am having the exact same problem, seems to happen when i charge over night on wifi and then after i unplug it in the morning, mobile signal drops . Mobile data section in settings also disappears. Not sure what it could be.
Now that you mention it, I did lose cell signal yesterday. I put it down to being in a bad coverage area, but once I got home it was still dead. Rebooted and it was back up to full bars...
I get it but it comes back if I use aeroplane mode on and off.
I'm in a well covered LTE area and minevnever gets higher than this. Also drops to Edge most of the day.

Has anyone had an issue with At&t VoLTE and 4G LTE not being displayed? I've had the phone since release and when I first put my sim card in and turned it on, I had VoLTE and 4G LTE. After At&t customer service updated my imei to the sim card, I lost both and my phone would only connect to 3G. I have gotten it to go back and going to the At&t store and them updating my imei with a LG phone and then doing a factory reset. I then lost it again because I had to do another factory reset to restore my phone apps and settings. Right now, my phone says 4G LTE but doesn't say VoLTE like it use to and I feel like my reception poor now. I have spoke to several At&t reps and they all are saying that its because the Nokia 9 isn't recognized in their system and automatically sets it to a 2G device.

If anyone cares, all 3 major carriers in Australia (or Sydney at least) support VoLTE. Tested on Vodafone, Telstra, and Optus.
No German provider would be supported

Still no support in Germany for any Carrier for any Nokia Phone.
I guess I'm done with Nokia. The 9 is ok, but Camera, Finger Print and no VoLTE/WiFi Calling are not working properly.
I think the Pixel is the next Phone.

In Poland T-Mobile support VoLTE and VoWiFi (WiFi Calling) for Nokia 9. Orange and Vodafone (Plus) don't.

I am also waiting for someone to test this. Regardless of the bands, Rogers do not always 'allow' 5G and VOLTE on their network for phones that are not officially recognized. I found this out with the Oppo FInd X5 Pro which cannot get 5G or VOLTE on Rogers. VOLTE is especially an issue as it means you cannot make phone calls if there is no 3G.
I am hoping the 12S Ultra does not have this issue and can get VOLTE.

Only seen LTE+. However my area doesn't get 5G and I haven't had a chance to test it otherwise.
What carrier are you on please and do you see the VOLTE option in settings?

I'm also on Rogers and have ordered the Xiaomi Mix Fold 2 which has similar firmware. I'm curious whether VoLTE appears in the Settings/Mobile Network by virtue of your SIM, or whether you can enable it with the Xiaomi dialer code (disable carrier check). If not, I assume you can unlock, root with Magisk and use a VoLTE enabler module or edit your build.prop to get VoLTE. Not an issue for us yet as voice calls drop to Rogers 3G network, but when we follow suit with the Americans and shut down 3G we will need VoLTE to make voice calls over 4G (or one day 5g VoNR).
Finally got my phone. Can verify 5G works on Rogers. I'm in Winnipeg. Cheers
Canadian - bought phone from PDAPlaza - on Koodo
all is working well from a network perspective
any of y'all that have the phone, are keeping the china rom, and have any good tips on how to tune the phhone (debloating, app settings or anything else) please post for us!!
I'm still experiencing alot of little quirks here and there that I can't seem to figure out
I have an unexplained connectivity issue I can't quite put my finger on as the main quirk - like the network performance is generally good and speeds are fast but..there's these times when it seems to want to take a sec to properly connect to a server. Examples would be if I focus Discord it'll say "connecting..." for like 3-5 seconds before refreshing the content - it's a strangely long lag for something so minor. Another one is if I open my friends list in Pokemon go it's unusably slow (while it connects to the corresponding pogo server) for like...5-7 seconds then is perfectly fine. Those are just examples but there's others where it's fine once it establishes the connection but isn't in any hurry to establish it
I haven't noticed any connection issues. Most of the Chinese stuff can be installed. The only issue I have is WhatsApp isn't showing contact names. Just profile pic and phone numbers.
That's just permissions. Allow it to use contacts and you should be ok
Hi there,
May I know can We Unlock WiFi 6E(6GHz) by flashing to EU firmware?
Like the default China MIUI firmware won't support 6Ghz when it's not enabled in China, but I don't know if there's 6GHz RF and Antenna which could allow us to flash the phone to EU version, then able to connect my new router which supports WiFi 6E(6GHz).
