wifi calling - Samsung Galaxy S9+ Questions & Answers

Hello,
I purchased a S9+ from Samsung for the ATT network. I just had my ATT account suspended due to a military move and had the phone unlocked. I just got TMobile service, the unlock worked fine, I still see the ATT stuff when it's booting and I know that's firmware related, but when I try to enable wifi calling, it let's me turn the slider to on, but as soon as I do, it closes the page and the calling option is still greyed out. Any suggestions, I am going to need this feature overseas.

I think wifi calling only works on the phone's network. If you change networks it stops working.

WiFi calling.

While in Mexico next month can I WiFi call to the US on my g3 ?
I have the HTC One (M8) and did my update (Which added the Wi-Fi calling app). I am currently in Mexico (Been here since Saturday) and I couldn't get the Wi-Fi calling to kick in while connected to a Wi-Fi. Everytime I tried to connect by enabling the Wi-Fi the location part of the Wi-Fi calling app would kick in and I would get a message something to the effect that wi-fi calling wouldn't work in my current location (Not exact words but that is what it would tell me). So I decided to turn off the locate me feature in the Wi-Fi calling app and enter my home address (from the US) and it said confirming address took a while and it seemed like nothing happened. A little while later all my text messages and my voicemail s started to show up on my phone and the Wi-Fi calling icon showed up on my status screen.
I'm going to be honest. I was also tinkering with the network connection settings and manually selected cdma/lte in the network mode and enabled Domestic voice and data. I just wanted to get some type of service (i didn't care if it was going to go into roaming because I needed to make calls back to the states). So I'm assuming I am using the Wi-Fi calling feature because I don't have the data portion on the phone turned on and I don't have international voice or data enabled. But I will find out on my bill next month.
If I'm really on Wi-Fi calling mode then the key (i think is to trick the location servive of the Wi-Fi calling app to think you in the US by typing in an address in the US and not letting the app locate you automatically to Mexico....
I was trying to upload screen shots from my phone but the web browser let's me. I will pots the images after the 19th..

I just returned from Mexico and had turned the wifi calling on my last day their. At first worked great made a few calls back and it worked crystal clear. Then it started to ask for location I tried everything even when it did accept a location over the border in the U.S.(I was in a border town) it stopped working. My friend who has the wifi calling from T-mobile had no problem. Hopefully Sprint (lol) will get a clue.

internet on WiFi only

I have a SCH-i605 on Straight Talk network using Verizon towers. It's rooted and running Bean's rom. For the past month or so, I cannot use internet with WiFi turned off or out of range. It's offline. In settings data is turned on. Airplane mode is not. Yet when I go to about phone/status/Mobile network state, it says disconnected whether WiFi is on or not. Straight Talk tech had me change APN settings which didn't help, then said it has to be the sim card. It's the same with the new sim card. Does anyone know what's causing this?

Unlocked SM-G965U1 and verizon wifi calling

Question How to enable VoLTE and VoWIFI on AT&T with unlocked Pixel 6?

Hi folks,
The title pretty much says it all. I've got a new unlocked P6 bought from Google, using it on AT&T here in the US. It doesn't show VoLTE and when I go in to turn on VoWIFI I get an error to the effect that "we couldn't turn on VoWIFI."
The VoLTE worked out of the box on my prior phone (OP6T) but I never attempted VoWIFI with it.
Is there a special process to go through, or do I need to chat up the ATT reps? It's possible I'm not provisioned appropriately; my SIM is the same SIM I've been using on several phones over a good number of years.
Before I go in "cold" to a conversation with them I'd prefer to know exactly what to ask them for.
Thanks
Here's their whitelist:
Note this is the latest updated list (edit)
I had to have them enable it for me. I did it via chat support. It broke the ability took make regular calls but a quick call back (from a different phone) and it was fixed.

Thanks. I will see about chatting them up. Hopefully they won't break my regular phone capabilities.

Funny thing before I chatted with them my Pixel 6 showed up on my account after they did whatever they did it now shows unknown device. It works so it doesn't really bother me. Edit: I have the unlocked version from Google as well.

Ask for "advanced tech support" when the dud robo attendant ask what for, repeat.
I posted (edited) the updated whitelist, with more models and harder to read
I double checked my devices... but the proof will be when they still are working.
Lol, what could go wrong?
Yeah, be afraid, be very afraid
On with chat now. Just gave them my IMEI. We shall see soon
OK, I'm all set. I think, or maybe I hope.
The chat function worked well. After getting past the chatbot I spoke with a real agent, explained my need, and she quickly took my IMEI and got it set up in the system. I got a text quickly that some ATT stuff got activated (I'll be able to turn on spam blocking and such). I was able to go in after a reboot and turn on wifi calling, leaving my preference as using Mobile Network.
I made a test call and it actually used the Wifi instead of mobile, which concerned me. I disconnected from my hotspot and tried a call, and mobile network calling worked fine, though.
Agent said my preference setting should take hold within 24 hours, in any case. We also went into the dial menu and verified VoLTE was turned on:
"Open dial and Type *#*#4636#*#* Choose Phone information option from test Screen. Now you can Enable VoLTE Support Provisioned Flag. Restart your device. Now you can see 4G LTE option under Network Bar. This will activate unlimited HD Voice Calls."
It was on and grayed out, so should be active. Just surprised there was no special icon showing in status bar like my old phone had.
Everything seems to be working so I think I'm good to go. Thanks for your help guys!
edit: after getting me set up she did a hard sell to get me to use the eIMEI for another ATT account. I declined.
How can I tell if VoLTE is enabled?

See my post above. Enter the code in the dialer to access the hidden menu. It will bring up a screen that shows some settings, one will be the switch for VoLTE. For me it showed on but grayed out, which apparently is the correct setting. If it shows off, that would mean you aren't provisioned for it and need help from your carrier.

*#*#4636#*#* Thanks, very nice. On my N10+/pie this is the only place were the VoLTE setting can be seen as a toggle which is on. Yay.
Oh, one other note. Wifi calling seems to be working fine, though I haven't had a chance to check its integration with Google's visual voicemail.
What I notice is that the decision to use wifi instead of mobile is kinda hair-trigger. At my home, LTE bars are low but calls always work just fine. However, now with wifi calling turned on (with preference being mobile network), the system usually decides to use wifi anyway due to low signal. I also noticed at a grocery store, where my phone auto connects to their wifi, that when I was in the back of the store (weak LTE) it switched to wifi calling mode, then switched back to regular mode in the front of the store (strong LTE signal).
So, the system is conservative and moves over to wifi pretty often rather than treating it like a last resort. I guess that is good behavior.

I have an unlocked P6 direct from Google on AT&T. I have it greyed out but on. Does that mean I need to contact AT&T?
I had never gotten wifi calling set up on anybody my previous phones, so I definitely needed to get that turned on/provisioned for my account. The rep also told me that adding my non-ATT IMEI was needed; indeed several options became available once that was done. I don't think anybody this was needed for VoLTE though.
So pat of this might just have been due to my account history.
To cap this off, I got a wifi call just now and it transcribed fine.

Not needed for VoLTE on AT&T as I can switch the sim card between my AT&T N975U1 and unlocked N975U seamlessly. However I never use wifi, tethering or more advanced features on these two devices... so no idea about that.

S9+ will only make/receive voice calls in duo mode

Just what the title says. My phone tells callers that I'm not accepting calls and when I attempt to make calls it simply refuses to do so or displayed a "call ended" message without ever dialing the other person. Everything else works fine and I can even make voice calls if I use duo mode instead of mobile. I can also receive calls if the caller uses duo mode.
Have been through everything except an actual reset. Unable to do that since the phone was a hand-me-down and I don't know the PIN. I've about reached the point where I do a hard reset manually but I hate to lose my data. Does anyone have anything I could try to either bypass or recover the PIN or something I could use to get mobile mode to work again?
Your sure you have service? If you do, do you have credit? Both of those would prevent you making calls. You can still use Duo if your on WiFi or you have a data only service. If you are showing that your connected to the network and you are certain you have minutes in your plan or credit available then you will need to call your network provider so they can see if there's any network issues preventing your calls. Check the network operators status page to see if there's issues in your area.
@Nofsdad
It appears that when using a Galaxy S9+ with ATT service the phone is unable to do VoLTE
The way that I was able to have internet on the phone and voice calling was to go into the APN and set the Network Mode to 3G/2G (auto connect)
That fixed it for me. Still pissed off that I can't use LTE but oh well it will work until I upgrade the phone.

Hello, I have an unlocked s9 that is going through a similar issue in not being able to make or receive calls. Can you let me know how you got the APN settings for 3G/2G? Going to APN settings I only see the nxgenphone setting open and active, which I heard was for LTE.
Also, can you let me know what setting it has to be in the 4636 mobile network settings in order to restore data? Thanks
