I was wondering if there is a way to get VoLTE working on a factory unlocked S8 that is using a AT&T Straight Talk SIM card. Right now when I make a call, the data goes to 'H'.
Anybody?
I'm not sure if it's possible but have you tried carrier switch your unlocked S8 to AT&T firmware. That's the only way I could get it to work on my unlocked S8 but I do have AT&T though as a carrier
How did you get it to work on att? I am on att as well and it does not appear to be working after carrier switching my unlocked S8 to att branded also wi-fi calling does not work.

It worked for me the first time but then the second time I went back to the Oreo beta they went back to AT&T I was only getting H after that when I was calling so I had to borrow my wife's phone IMEI and they provisioned it and it worked again
so how exactly do i go about doing that? I assume this involves calling att or going into a store and giving them the imei from another phone? Does the imei you use have to NOT be already used or can it be in use by 2 phones at the same time? Also so far we have not even told att about this phone we have just moved the sim card so wouldn't they still have the imei of the old phone or do they pull that automatically OTA? If they do pull it automatically then whats preventing it from getting updated again?

Hi guys,
I bought the unlocked firmware phone back in December 2016. The phone is great, the problem is I am using EcoMobile MVNO. It's refusing to recognize the network with the MVNO's sim card. I've spent hours on the phone with them and they claim all is OK on their (and Verizon's) end.
The phone sort of works, so I've just been grinning and bearing it so far. Using 4G switcher, I can put it in CDMA only mode, in which case it connects to '123456' and I can receive and make calls, and receive texts, but have no internet. If I put it in full LTE/GSM/CDMA auto mode, it connects to LTE, so I have internet, but it claims I'm not connected to Verizon network and in fact it's not available. So in this mode I can't receive calls or texts. Can't send texts under any mode. I've done a full factory reset at the MVNO's behest, of course that did nothing. The phone seems to connect fine to Verizon's network if I borrow someone elses's Verizon sim. My MVNO sim also works in my wife's iPhone5 without a problem. So it really seems to come down to the firmware on the phone. I'm holding out against hope that when Nougat comes to the G935U firmware, this problem is magically solved... but just in case decided to post here.
Please help, any ideas would be appreciated.

Flash the vzw firmware or go through the steps for the hybrid rom with vzw modems implemented.
Thanks. I was really hoping for something less intrusive, maybe some CSC edit fix, or some such.

Welp, the 7.0 update is here, and it didn't fix my issue, in fact now I can't even get LTE data as I used to get. :crying:
So I had this issue when I first got the nougat update. When I got my S7 I put in my brothers sim card to made sure it worked on Verizon cause i was buying it from someome and anyway I activated my straight talk verizon SIM and everything was great until I got the update and my service was weird and I didn't know what to do and then it dawned on me, I put in an actual verizon SIM card, doesn't need to be active let it register and then put your SIM back in and everything was great! Hope this helps...
Switched to TotalWireless, phone works now. They first sent me a SIM which didn't work, then had to send a different, post-paid one.
I now suspect if ECO also sent me a postpaid based SIM it would start working. Things are always way too complicated when Verizon is involved.

I'm tempted to try this as I'm having the same problem with my 935U and Xfinity Mobile (Verizon MVNO) SIM, instead of connecting to the Verizon network, it connects to network 123456. I did load the 935V firmware, which worked fine, but I'd prefer to return to the U firmware if this would work. Is this still working for you, and if so, do you just need to put the regular verizon sim in once and from then on the MVNO sim will work, and continue to work including after a reboot?

I put in a Verizon SIM in it once and that was after the nougat update. But every time the phone restarts, I have to make a phone call for it to connect to the service or it will just stay stuck in "searching for service" but once the phone call connects, I hang up and everything works as it should.

Thanks, strange problem. I'll probably just stick with the 935V firmware for now as that's working fine (just have the Verizon bloat and failing the hotspot check). I also have a dialog going with Samsung support to see if they're aware of the problem and have a fix.
Is it possible to get volte working on Unlocked Firmware S8+ with straight talk at&t
I've got a att s8+ phone as well as a tracphone s8+ which are both on the unlocked firmware and upgraded to the oreo latest beta. I'd like to get volte working but not sure if it's possible.
Thanks!
Actually may have found a work around to make it work myself and this may help others.
I was able to put in a T Mobile Sim which rebooted the phone and added whatever settings. Then once it was booted, I put the straight talk sim back in. The volte menu option was not under mobile settings prior. If you click volte off, it will disapear. If you leave it alone, it keeps it activated. I turned off the phone and on and confirmed, it retains it. Called a friend who I know has volte and you can tell the connection is volte. It appears atleast to me that the sim turns on the option and the straight talk sim alone does not support lte but the network does.
Good info, thank you.
According to ATT and Samsung the SM-950u is not att branded, they are been sold in swappa as such, i bought one and found out wifi calling wont work on this device as even do it has att firmware and the bloatware it wont provision. any ways to get this done by flashing the wifi calling provision from att
I had this working by flashing the att fw to a u1, and using my att sim, then i changed my imei to an att s7, but it stopped working and my ims registration turned off. I think they suddenly can cross the sim to the imei and block it. The imei on my account updated to show my u1 on its own.
I just got my S8 unlocked from Sprint, the UICC says it's unlocked for all sims in the settings. But I've tried both an AT&T sim and a T-mobile sim. The tmobile splash screen comes up and it even shows the tmobile phone number in my about phone settings, but I can't get any data or calling or anything to work. Same for AT&T. It even says AT&T up in the top as carrier but nothing works.
Do I need to do something like flash it, or is it possible they only did international unlock is why this is happening? Or is it because I still have Sprint service on the phone? All I know is in settings area for UICC it says any sim will work, but it's not working.

Sometimes service is dependant on the apn settings. Check those and make sure network settings are swapped to global. Also radio switcher app.
Lastly the sprint firmware may not have needed bands enabled. These are all the things to check first
I already SIM unlocked my T-Mo McLaren 5G (and waiting the 7 days for bootloader unlock) but I don't have any other carrier SIM on hand. Can anyone test the McLaren 5G with other carriers and let us know if it is working fine/how well/how it compares to original carrier phones? (SIM Unlocked McLaren 5G of course) Thank you!
probably not much help, but my LOCKED T-Mo McLaren 5G ran a mint sim exactly like the t-mobile sim. so, t-mobile mvno's should work.
cheaper plans same 5G coverage.

Here's a screenshot of where I unlocked phone after it was granted the unlock from the reps! Hope this helps
Ok I did that but I got a failed and I hit up TMobile they told me that's wired because on there side it's eligible for unlock. They can't pin point why it's getting that error

How? I tried the network unlock from settings as shown above and I get "Unlock Failed" Error Code=255
I bought the phone online and I live in Canada so I can't even make a T-Mobile account and they wouldn't do anything regarding a network unlock over the phone when I wasn't a customer.
Tried a few websites but they all say the IMEI registers as CDMA yet the phone has a SIM card slot and the specs say GSM so I'm very confused as to how to get his unlocked so I can try and use it on Bell.
mine worked on freedompop att, on mint now, same 5g as t-mobile

You should check and see if it has been blacklisted. If not you can possibly use Mint Sim. Mint Sim is an MVNO of T-Mobile which you can use without sim unlock I believe.
It will NOT work on Verizon at this time. I've spent hours on the phone with Tier 2. The farthest I got was " I filled out a form to have yours added to our DB and I'll call you back in a week either way". Needless to say, that call never came. I can get Data using my VZW SIM but no calls or texts.

Just a quick thought... Did you try installing the Google Dialer and Google Messages to see if it was the Oneplus apps preventing the calls and texts.

Unfortunately, unless the IMEI is in the VZW DB, you won't get SMS and I'm unable to make calls. I read a few people were able to make calls but no SMS/MMS or RCS messaging. From what I've read, calls should not work due to the IMEI issue. I honestly don't understand how anyone could make calls with a VZW SIM.
As of software version .25 today, Verizon CDMA-less sims now work. Previously only data came through, now talk/text/volte are all functioning. You'll need to have the SIM provisioned CDMA-less with a different CDMA-less phone before swapping the sim card in. Note that as of software version .16 however, band 13 support has been removed.

I thought 13 was the primary band for VZW LTE? If it's gone after .16, wouldn't updating to .25 be an issue?

It is their main band, but VZW has a lot of band 5 around and thick cell density so it would still be usable, just not the best experience possible. Version .13 had band 13 enabled, but I never tested .13 to see if VoLTE was working.
As of last night. Still no go for me. I had one of my VZW Sims put into another CDMA-less phone, called VZW and had them make that SIM CDMA-less. That phone worked for calls and SMS. Shut down that phone and the McLaren, swapped SIM but same problem. No calls and no texts. Called back and was again told my IMEI is not in the VZW DB.

I have a Verizon tracfone line tied to a Oneplus 7 Pro, moving that sim to the T-Mobile 5G McLaren works after a reboot for calls/text/VoLTE. Maybe something is happening on postpaid VZW causing CDMA-less to be removed when you're moving the sim, I'm not sure.
VZW finally added the 7T Pro McLaren to their DB. I put my VZW SIM in and booted it. I was able to make and take calls and send texts outbound. I called VZW and had my line setup as CDMA-LESS and started getting texts. Data is working fine.
I tested a Verizon prepaid SIM. It connected to LTE and data, SMS and phone call all worked with no problem.
I'm on build 10.0.25.HD61CB
I've never contacted Verizon about this and I'm not provisioned in any special way. When I ordered the Verizon service I signed up with a BYO Pixel XL.
I have to pay my t-mobile one plus 7T pro mc claren phone completely off before I can get it sim unlocked by t-mobile right? Thanks In advance for any information on this topic. Thanks!!!
