Restore wi-fi calling - carrier unlocked - T-Mobile Samsung Galaxy S8 Questions & Answers

Hi. I'm new (and old) so apologies in advance for any faux pas. I couldn't find another thread with a problem like this, so I'm posting a new question.
Here's what happened:
I have been using Ting MVNO SIMs on two Galaxy S8 phones for about 18 months. Preparing for an overseas trip, I asked T-Mo to unlock the phones so I could use foreign SIMs.
T-Mo unlocked the phones, but now I can't get wi-fi calling to work on the Ting SIM. Tried a MintMobile and FreedomPop and the same thing, no option in the tools or phone app to activate wi-fi calling although it is activated at the MVNO and the E911 addresses are correct.
T-Mo says it's impossible that unlocking did that. Well, it happened. Ting doesn't have a clue about how/why it happened or how to fix. Samsung says it's the carrier's problem not theirs.
I factory re-set hoping it would restore the lock, but that didn't do anything. I don't get a signal at my home, so wi-fi calling is necessary. My next step is to buy new phones.
Ideas? Thanks!

3G not working...

Briefly, I have had a few issues with my device. One was the inability to register my S/N on HTC's EU site. Several other reports of this have surfaced as well. That is being addressed through MobilePlanet's very helpful rep James. Glitch on HTC's database apparantly. The second, as Dan mentioned, is my phones total failure to see the 3G network. I now know why...
I spent almost an hour on with AT&T's data support and the guy said the reason was the failure of my devices IMEI# to register the devices hardware. There seems to be no hardware profile for the TyTnII ansd therefore it comes up as an "unknown device" in their provisioning system. I confirmed this on my visit to the store this afternoon as the rep there showed me the screen and sure enough, it comes up as unknown, and the setting for this selection is GSM, not UMTS which all of their 3G phones are set to. He said, your device "does not exist" in a valid profile as a UMTS device and therefore will never be able to see a 3G signal even if I was sitting under a 3G tower... He showed me his phone which is 3G capable and id did indeed have UMTS and a valid hardware profile.
So, looks like I am SOL for 3G unless MP can help. Not happy tonight... I am going to speak with MP again tomorrow or Monday, and see what they suggest, if this can't be solved, I may be returning my new baby. 3G was an important selling point 4 me as I do a lot of data xfers.
BTW, I'm in NorhtEast NJ within a known 3G area. area.
hummmmmmm??? granted i'm in dallas, but, i'm on AT&T and i just popped my 3G SIM (used for a 3125) into my Kaiser and i get 3G with no issues. i would have tried the ATT guy's SIM in your phone (and vice-versa) to validate the profile issue. you didn't mention this, but i assume you have a 3G SIM , correct? i'm interested to hear if other ATT users have had this problem....what about trying a new SIM or one from a friend that has 3G?

Yes, that will work. Per AT&T data support, since mine is an unlocked unit with an IMEI# not in ATT's system, it will never be able to do 3G. Everyone that did get it to work just switched out their existing 3G capable sim to the new Kaiser. I came over from Verizon, so unless I buy a cheap 3G ATT phone, I'm out of luck.
Switching the sim for a new one did no good, same IMEI#, so no help.

I made the mistake of giving at&t my new IMEI# when I went from the 8525 to the Kaiser. Now my phone profile is set to GSM only since it is an unknown profile in there system. I will either have to buy a cheap 3G phone and use that SIM and IMEI# so there system thinks I have a 3G phone or return the Kaiser since I won't be able to get 3G. Right now it is not an issue since I don't live in a 3G area. hhhmmmmm

There is no need for 3G SIM card. Any card should work. I'm using old AT&T Blue SIM with no problems at all.

True any card will work. Did your old phone have 3G on it already when you swapped it?

Bill will test it tommorrow when he borrows a persons sim who has 3G. If it works then they are correct.
You got a pretty good load of BS from the AT&T guy. All you need is a 3G capable phone and the right provisioning to get access to the 3G network. Signing up for a MediaNet, MediaMax, or PDA plan should so it. YOu should NEVER give them your IMEI # unless it is an AT&T phone. Cuz at that point, if there are any issues that require deviations from their "scripted" support, they will say that's the issue. Unless you happen to get lucky and get a real technical support rep.
Just tell them you got an aftermarket unlocked Blackjack and you want the 19.99 MediaMax 200 plan. If they ask for an IMEI number, tell them that shouldn't matter. You can then make any changes to your plan online if you'd like. And that should get you access to the 3G network.
Thats the problem. Talked to several CSR and they won't change the provisions becauses we did give them our IMEI numbers already. They got us there but there are workarounds and lesson learned.

Not so -- my last two phones (Kaiser & Wizard) have been unlocked & not registered with AT&T, and I get 3G HSDPA. However, I don't have (and never have had) a data plan -- I pay $0.01 per KB for data a la carte.
I have a suggestion based on what i'm facing: try disabling the HSDPA in settings and reboot (it will ask you to reboot anyway) then see if you have 3G.

That is total BS sounds to me you dont have the right settings on your phone. Did you use the Network wizard to set things up for you? that might be the problem if you did. I have AT-T and a brand new Kaiser direct from HTC and have no no no issues what so ever with 3G or HSDPA i also think i am getting a little a HSUPA here and there
FYI and a request for some assistance
I use quite few different phones and one day my account froze on me. I had been using a palm treo 650 because my kaiser was out of battery.
when i reinserted the sim into my kaiser days later phone worked but no data no sms worked again. in any att phone all shapes and sizes. I thought it was from the treo because i used the data no problem.
its a company acccount need password to talk to csr at att.
after researching and seeing this thread I retracted my steps
the only other thing i have done is reported an imei on my account for a tilt i needed to unlock for a friend before there was an unlocker.
I believe the imei on file controls my provisions.
Provisions
the only solution to no data on phone that was working is provisioning a pit stop to a service center.
Is it possible to create a solution or is it totally a carrier fix at this point? Is there any other way to adjust provisions with out a walk in or call?
FYI
to change a reported imei number simply call 1-(916)-843-4685 and have them update your device to what ever imei you want them to have.
Note once they update the system make all your changes for rates online the only info att has is what is provided at point of sale or givin by the client
this is just some info to add

[Q] Verizon LG G2 GSM Support

Hello All,
I have been thinking about traveling to Japan this coming year; I have looked at Verizon's International plan, and it seems like they are very pricey.
I have heard that the VS980 has GSM support, with no LTE, which is fine. I have looked into the h20 network, as they have exceptional prices for their international plan.
I have googled it and have gotten mixed answers, so I came here. I have a h20 sim card, and it pulls the APNs, but does not get any service. Is it that I am using a custom rom?
Thanks for the help in advance! :laugh:
aerial irrntsrt
Please someone answer this. I'm in a similar boat.
I'm on the stock verizon ROM. I have a Piranha mobile sim card. I am testing the setup in the US to verify it works. It connects to the T-mobile/Piranha voice and sms network, but data is not working.
Their setup instructions call for setting the apn to openroamer.com, but no mention on the mnc or the mcc values. If I just set the apn to openroamer.com I'm able to save and select it, but as soon as I change the mnc or mcc values to t-mobile the apn disappears after I save. Do I need to set the mnc and mcc values to something specific? I tried to track down exactly what they do, with no luck.
I see mention in another thread that Verizon locks the phones to be unable to connect to other US domestic networks. They also mention that once I'm overseas I'll be fine. I'm skeptical.
I was thinking of going to the t-mobile store to see if I could borrow a sim card to confirm it's a firmware issue. I would rather not root at this point. Any other courses of action?
Thanks for shedding any light.

It turns out to be a activation error for me, after I correctly activated the sim, it worked! (silly me!)
For your problem, I looked on your carriers website/ help websites and there are no values except the APN.
You might need a data plan active. I would try using other carriers, because for me the h20 sim worked with data.
Verizon has no control over what network you go on either, FCC has a couple laws that prevent from Verizon doing that except exclude the hardware needed to connect to other networks.
Sorry I could not help.
I popped my Aio Wireless (AT&T) SIM from my Nexus 4 into my G2 and after a little APN tweaking I had HSPA+ working with no issues. It is my understanding if you have AT&T Band 4 LTE (limited markets) and the correct service providor, it will even connect 4G/LTE on AT&T networks. I swapped my Verizon SIM back in and removed the APN's and all was well on Verizon again. I am stock (KitKat) and rooted with only a few few Xposed modules installed, no custom ROM.
It sounds like, from reading the posts above, the Verizon LG-G2 IS a World Phone and should function straight on from stock on a UK provider like Three just by purchasing a sim and plugging it in then configuring the APN settings !
The problem is that when my Susan went just this morning to a Three store in London, the guy there told her that her Verizon LG-G2 was LOCKED to Verizon network only, and that she would have to do something like obtain an unlock code because the phone would not work on any other provider until she did that.
Verizon's International folks told us earlier that the phone would work fine, given GSM frequency issue restrictions, overseas and there was no need for any UnLock proceedure or code.
Does she just need to find a competent tech at a different Three store ?
Or is she going to be unable to play Ingress the whole two weeks she is over there in England and Scotland ?
Update...both Three and Vodaphone folks in London have now told her that the Verizon LG-G2 is carrier locked and cannot be used without Verizon unlocking it on any other network. So, Verizon was wrong and she is limited to WiFi only for the next two weeks ?

No global mode Verizon phones are carrier locked.

It is very odd. We tried it on a T-Mobile sim over here before she left, I am pretty sure, and it just worked. Still, over in London Three & Vodaphone say it is locked and useless on their networks and their sims don't work.
Maybe it is subsidy-locked ?
Maybe they just didn't set the APN and data settings right at the stores ?

Can't Activate Note8, fails on configuration with Sprint & Boom Mobile

Hi Guys, I'm wondering if someone more knowledgeable can help advise. I've spent 12 hours and cant activate my Unlocked Qualcomm Note8 on any of my service providers (SMN-950U1.)
I want to use it on Boom Mobile Red (Verizon MVNO)
I cant get the Network Operator to configure, when I select Verizon it fails on configuration. I'm not referring to APN because I do not even get calls, the Operator is listed as "Emergency Calls Only". The Sim works perfect on my Pixel XL and iPhone 7 Plus. This phone was purchased unlocked form Samsung direct with clean IMEI. I called Samsung and they have no idea, they said the phone is defective, which I believe it is not.
I had an issue activating with Sprint and still have not had Data working, though I was able to get calls. I've given up w/ Sprint and will upgrade that line with a iPhone X.
I inserted my friends Verizon Post Paid Sim from his Moto Mod phone and everything was perfect (calls, TM, LTE calling) and the phone got LTE+. Is it possible the Note8 unlocked will only work with the big 4 carriers, ST and TW? I read a similar issue people from Boost Mobile have when they insert their sims it says invalid Sim. I really have no idea what is going on - Boom doesn't have many customers and their support team has never delt with this issue, they said the phone is defective. Has anyone been able to use a Unlocked Note8 on Boom? I've tried flashing various variants of firmware, including Verizon with no success. I'm puzzled with what is going on.

No Voice over LTE

So, I finally talked my wife out of her LG phone and got her an identical VZW Nexus 6. So we now have identical phones. I have unlocked the bootloaders, installed TWRP, and both are running CarbonROM weeklies.
For some reason, my phone has voice over LTE, and everything works just fine. Hers drops LTE every time she makes or receives a call. I've been searching xda and google for 3 days, checking and double checking that all settings match on the phones, flashing different radios, etc. And the setting for "Enhanced LTE Service" doesn't even show up in her settings.
If I put the preferred network to "LTE", (same as mine) she can't even make a call. It acts like it's going to dial, then drops signal completely.
Any ideas?
I would check and make sure Verizon has it provisioned to use volte
How would I go about checking to see if it is provisioned for VoLTE? It is on straight talk service now. When I contacted StraightTalk support, they told me that their service doesn't support it. And they didn't have an answer after I told them that mine does it just fine. LoL
Actually, they said maybe the phone needs an update...
Clarify the following. Are both N6es on Verizon, both on Straight Talk, or one on Verizon and the other on Straight Talk?
The last time I looked into it, Straight Talk didn't support VOLTE. Has that changed?
They are both on Straight Talk, using verizon sim cards. The tech support told me the same thing. That they didn't support VOLTE. And had no explanation when I told her that my phone was using it just fine.
It doesn't function on the AT&T side of Straight Talk and AT&T definitely has VOLTE. Thus, the fact you have it is an anomaly, and your other device not having it isn't an issue with the device or its firmware. In other words, consider yourself lucky.
Well, I'm not one to give up very easily. So, after some thinking, I may have come up with an idea.
Both phones were purchased from Swappa. My phone was listed as a Verizon phone, while the other was listed as an unlocked phone (no idea what carrier it was previously used with).
I'm thinking that adm1jtg may be correct, My phone would have been provisioned for VolTE, and the other phone may have never been on their network to get provisioned...
So, I think I will switch her to Verizon prepaid which doesn't cost much more and see if that fixes it. Maybe after a month switch back to straight talk. I will update this post afterwards, and let you guys know if that does the trick.
Maybe overthinking it a bit. After I switch her to verizon prepaid, and get her phone all set up and see that VoLTE is working, I'll pop my straight talk sim in it and let you guys know the results...
Soo... I had some time to think about it, and decided to just swap sim cards between the two phones. Turns out, it isn't her phone at all. With my straight talk sim, her phone got Enhanced 4G/Lte.
With her straight talk sim, my phone did not. Put my straight talk sim back in my phone, and Enhanced 4G/Lte came back.
Turns out that Strephon Alkhalikoi is correct.
I wonder how many BYOP sim kits I would have to go through to find another anomaly... LoL

Activate Wi-Fi Calling on 4XL via command? I've seen it...

Wi-Fi calling is no longer working on my 4XL. I have Verizon on an unlocked 4XL.
The options are completely missing. I've spent over 4 hours on the phone with Verizon tier 2 tech support and gotten nowhere. They insist that Wi-Fi calling is active on my account/line and that its an issue on my phone.
I should mention I have a dual SIM setup running both Verizon and T-Mobile, T-Mobile is an eSIM. That said BOTH worked fine until I popped my Verizon SIM into a Verizon Mi-Fi and the SIM from the Mi-FI into my 4XL.
Verizon said they could see the two units reprovisioned but as far as Wi-Fi calling on the 4XL, it's active and SHOULD work but its almost like the Verizon software is blocking it the settings from even showing. I have NO options for Wi-Fi calling under the phone settings anywhere, they are gone but I do still see them for the T-Mobile eSim.
I remember back in the day Verizon blocked Wi-Fi calling on Pixel devices that were unlocked and or not Verizon branded. There was a command-line you could run to "unhide" the settings and turn them on.
Does anyone have anything like this for the 4XL? Verizon said I may need to completely factory wipe my 4XL but I have it setup perfectly, I really do not want to do that if possible.
Thanks!
I use 2 SIMs as well. My T-Mobile account is ESIM and my Visible is physical sim. I have no issues with WiFi calling on both. I attached a screenshot, do you see the same menus as me? Also, is your Google pixel the Google store variant or a carrier?
Here is my TMobile settings.
