Hello everyone! I have a question, which I'm sure I already know the answer to, but figured I'd ask all the smart people here.
I have the unlocked 2XL from the Google Store using Project Fi. I have both an eSIM and physical, both giving same results. My phone always defaults to Sprint as the carrier of the three (Sprint, T-Mobile and US Cellular). I can forch jump to T-Mobile or US Cellular, but my phone will always default back to Sprint after a reboot or after sitting for about an hour. I've also purchased FiSwitch (amazing app btw), and I force jump to T-Mobile using it and even the dialer codes (same difference), but it always goes back to Sprint. I reached out to the Dev of FiSwitch as well and was instructed FiSwitch can't force it to stay on T-Mobile. Sprint's service is just subpar to T-Mobile in my area (home and work). T-Mobile provides better signal strength, quality and network speeds. I'd love to make T-Mobile my default unless I choose to change it.
My question... Is there anyway to force my phone to always use T-Mobile as the preferred carrier? Through build.prop or other means? My guess is this might be programmed into the radio, meaning I'm probably out of luck. I am rooted as well, which hopefully will help me with replies. Thank you!

Thanks for the quick reply! Those codes, along with FiSwitch are what I've been using. Unfortunately, after force jump to another carrier from Sprint, my phone will always move back to Sprint after a reboot or after just sitting for about an hour. Force jumpting to T-Mobile, for example, doesn't actually turn off the auto feature permanently. Per the FiSwitch Dev, he's not sure there is a way to force it to jump to and stay on T-Mobile, the phone after sometime will always jump back to "auto", putting it back on Sprint in my case.
I guess I'm looking for a way to not temp jump to T-Mobile, but force my phone to always use T-Mobile unless I chose otherwise.

I have that app, it's the one I mention in the OP. It can force switch, but it's not permanent.
Hey! Have you had any luck with it? I’m facing the same issue...
I've not found a way to force lock it to a certain carrier, but I did find by accident that using the "next" option with FiSwitch, cycling through until I land on the carrier I want, it will stay there until I hit an area where it drops, in which case it will automatically switch to another that works in the area.
I basically sit locked on TMobile now except one area I go where TMobile doesn't work well and it will jump to Sprint. I just hit "next" in FiSwitch when I leave that area and lock in TMobile again. :good:
Woah, thanks a lot for your kind reply. I’ll see how it works on my pixel. Strange, that they haven’t came up with a solution for a longer period of time as looking around, much people has this kind of issues.
Thanks for your prompt reply!!

My phone on reboot will default to the best signal, I live in Chicago but work just over the border in Indiana, when at work often my phone will reboot to Sprint, but as I cross back into Illinois it will go T-mobile on a reboot. I am using an E-sim. I also use Signal Spy for my switching needs.
What happens if you only use e-sim?

I get the same results with ESim vs physical. I just mainly use physical over the ESim because of my flashing between stock and custom ROMs and Google 2FA is a pain with only an ESim since the phone is not activated until I actually login to my Google account whereas with physical SIM, I can get a SMS backup code right from the start. :good:

I know this is not exactly what you want but what if you used Tasker to do the switch to Sprint for you on reboot.
Only decent workaround I could think of.
I currently have an Unlocked Galaxy S9+ directly from Samsung running on Verizon's network.
I can't seem to find a way to enable the HD Calling/Video Calling/Advanced Calling features.
Some rumors suspected if you installed the MyVerizon app it would enable the advanced calling menu, but that didn't work.
Is there any way to enable these features?
Is there a command through ADB to enable this?
Would I need root access?
EDIT: Model Number: SM-G965U1 - Snapdragon
No way to get Video and WiFi calling to work (yet), but go to Connections, then Mobile Networks and you can turn VoLTE Calls on or off, which is HD voice. It was there by default on my unlocked S9+ on Verizon. If you don't see it, you may need to add HD calling to your Verizon plan (it's free, but you have to login to the website and add it as a feature).

Ahh, I already have VoLTE enabled. Guess I will have to wait until someone finds a way to enable those other features.

Yeah, I know that they support video calling, along with a ton of other apps, but there is a native video calling option.
They got it working on unlocked S8, using some of the APKs and CSC from the Verizon phone. See below:
https://forum.xda-developers.com/ve...to/how-to-video-wificalling-unlocked-t3615027
Or just by flashing the whole Verizon firmware on the unlocked phone (kinda defeats the purpose of getting the unlocked phone):
https://forum.xda-developers.com/ve...axy-s8-unlocked-version-wifi-calling-t3699806
So I'm hoping it's just a matter of time, as I also need the WIFI calling to work on my unlocked phone. I think that's what is needed in order to send texts over WIFI via the Verizon Message+ app, which is what I ultimately need when in poor signal areas (sending texts over WIFI, without getting a second number with Google Voice or asking people to install secondary apps like Allo/Duo). Or I could just switch to T-mobile I guess, where all these things work with the unlocked phone without the additional hassle.
Here is to hoping we can get wifi calling and native video calling working on the unlocked s9/s9+ phones for those of us on verizon.
I have the S9+ (G965U1), and I have used the included Wi-Fi Calling app.
Look for Wi-Fi Calling.

I just got my unlocked S9 what do I need to do to get everything working on VZW I mean HD Calling, and video calling etc.? I've never owned Samsung Phones, I've always had unlocked bootloader HTC phones that I could do anything I wanted with. I don't know anything about Samsung accept "Odin". I still havn't put the sim card in cause I was thinking of returning the phone.
Thanks for the hint Dudeman456! I found WiFi Calling under system apps and went to its settings and activated its permissions. Now I can send text messages over WiFi using Verizon Message+ app (and not the included Messages app or Android Messages). I still don't have WiFi calling through the default phone app on S9. I wonder if there is a different phone app that I need for that purpose (Verizon Phone app?).
Same issue as my unlocked Note 8 I got from Sammy. You can enable video calling in the *#*#4636*#*# menu. You will not be able to activate WiFi calling though unless you flash the Verizon firmware. You also will not be able to use any Verizon features such as watching NFL games (but I think that is changing and won't be a Verizon exclusive) and premium visual voicemail. Really is a deal breaker for me.

What in the world does this mean "*#*#4636*#*# menu"????
All,
This is a KNOWN issue with Verizon.
I got my S9+ on Wed 3/14 from pre-order and could not get video calling to work. Went to Verizon store on Sat 3/17 preparing to wage war with them. The Verizon tech stopped me in my tracks and said it's already known. An email sent from corporate to all verizon stores indicating the problem with video calling. It is an issue with Samsung software which they are "diligently" working to correct and will push an update soon.
Notice this.. go to either MyVerizon app or the website and login. then go to devices/manage devices...then go controls then to adjust service blocks and you will see the video calling is blocked and cannot be unblocked. Apparently this is done for "our own good" until Samsung fixes the issue.
No date from the tech on when a fix will be issued.
DONT try anything crazy to enable video calling..just be patient and wait for the fix. My S9+ is unlocked too and i was assured that video calling will be enabled once a fix is issued.

That is odd. I am using my G965U1 on Sprint and my Wi-Fi Calling app is in the regular app drawer with everything else. I did not expect it to work, since it is Sprint, but it did. The Wi-Fi Calling app was available before placing a sim card inside.

I don't think it will unblock. If you didn't buy the VZW branded phone you most likely won't get video calling. I assumed this from the start. I spent a good portion of the day speaking with a VZW 2nd level support engineer supervisor with 20 years experience. He asked is there anything else that could be done besides unblocking video calls to make me happy, because that at this time it is impossible as the phone is not a VZW phone. Look in you phone profile on their website, does a picture of your phone show up? My profile is blank, that means the phone is not in their system of phones, even though I flashed the full VZW package with bloatware and all after first a full reset. My Phone has VZW splash screen and all the advanced calling menus, in about phone it says SM-G960U, but that block cant be removed. Maybe I screwed up somewhere and alerted them by booting with a sim card in? Maybe they flagged my IMEI? I don't know but the rep said point blank they can't unblock video calling on that line, and unlocked phones are not supported.
Are you all seeing LTE+ (carrier aggregation) on your Verizon S9 devices? I'm in Vegas and my device appears to sit on B13 (700mhz) and does not hand off anywhere else.

You need the right apps for Wi-Fi calling and some in framework. I don't own a s9 but that's what you need to do to get it to work. Along with some csc edits
I've called both Sprint and HTC and they point the finger at each other or think I cant read the menus. They tell me to go to the Sprint store which is in another town. I've called them multiple time over the past year. The M8 and M9 could do it why cant this still current high end model do it? I really could use wifi calling as my new employer has real bad signal but good wifi. I'm open to rooting/modding, as a last effort I 'upgraded' to Oreo and I'm not thrilled with it.
There is no mention of advanced calling or wi-fi calling in any of the settings menu. I do find internet calling, but I don't think that is the same. Help is greatly appreciated.

I've just started looking into this as well. For a short time I had a Verizon branded HTC-10 and that was GSM. It showed the Advanced Calling sub menu and configuration for WiFi calling. But my Sprint CDMA version does not. It appears to be locked. I've read elsewhere that unlocking the phone will "open it up" such that WiFi calling is available. But, it's no guarantee that you'll be able to use it. You have to check with your carrier's administrator. In my case, I'm with Ting and they're an MVNO for Sprint.
Hey all, I've been pouring over the forums here and other places trying to find a solution to my issue. I just got a Pixel 2XL the verizon version and I'm using it on Straight Talk with an AT&T sim card. So far so good except I cannot get wifi calling. I'm pure stock, android 9/Pie, no bootloader unlocks/rooting etc. The wifi calling option does not exist in the phone app nor in the settings anywhere. Even when you search for wifi calling, it simply takes you to the network and connections section of settings but wifi calling is no where to be found. I've tried the adb command (the one that apparently used to work on Oreo but not longer does on Pie) and that didn't work (though I didn't expect it to since many people said it no longer works on Pie). I have an Unlocked Note 9 as well and its wifi calling works perfectly fine so does anyone have a way to make this work? Reception at my home is somewhat lacking and I really need wifi calling.
Thanks!

Could you attach a screenshot with the WHOLE section of "Mobile Network", found inside of "Network & Internet" in the Settings -- make sure that you click on the drop down menu next to "Advanced Calling" -- this will help make sure that wifi calling is really missing as well as might point something out that may help with a solution. Moreso, personally, because I can't even imagine what the settings menu looks like missing this...

It might be a long shot but try checking the settings in the Google phone app. There should be a place that says configure IMS calling. I have this setting here and in the network settings. If you have it that's where you can enable wifi calling.

Been there done that. I have no options for setting up IMS calling. I only have SIP options. Also, I have tried the phone dialer trick (where you dial *#*#4636#*#*) and that shows the wifi calling option as a toggle but its greyed out and cannot be enabled. I even tried an adb trick that used to work on the 1st gen pixels, but to no avail.
What happens when you enter your information here?
I'll have to initiate a chat with Straight Talk. Like you I have a Pixel 2 XL with a Straight Talk AT&T SIM. The only difference is that mine is unlocked. I just ran my phone number and the IMEI of the SIM through the linked site and it tells me my device is not compatible. Since I have a BYOP SIM and the IMEI is of the SIM itself, chances are high that the SIM needs replacing with one that includes WiFi calling support.
EDIT: According to the representative I just spoke with, there's no guarantee that changing to a newer AT&T SIM will enable the feature. The only guaranteed method according to tech support is switching to a T-Mobile SIM.

Hey thanks for the help. I tried that link as well (before I posted here; sorry I should have mentioned it) and it said my device is also not compatible. I initiated a chat with them and they told me the same; switch to T-Mobile. I am tempted to do so but the one thing holding me back is my home is already a place I get poor signal and T-mobile's coverage while much improved still isn't as good at AT&T's. I realize that having wifi calling would fix any lingering signal issues but I do manage to get 1-2 bars of 3G at my house with AT&T, I figure I won't even get that with T-Mobile. So I am weary of the switch. I'll have to consider it though. I could also wait for the full rollout of the latest google voice (since it finally is bring VOIP without the need of hangouts) and just use that number instead.
So I contacted Straight Talk and ordered a T-Mobile sim card. It'll be here in a few days. I will post my findings after it arrives. Straight talk support says wifi calling works with all T-Mobile sim cards so we will see.
Hello all,
Okay, so I finally got switched over to a T-Mobile sim card (again still with straight talk). It took a while cause I had to buy a new one (the old one I had expired; who'd have thought?). Anyways, switching to T-Mobile solved all my problems and then some. Not only do I have Wifi calling, but also HD voice, VOLTE, Tethering, and 3-4 bars of LTE (previously on AT&T, I got 1-2 bars of 3G). I realize the signal issues is merely a coverage thing but I can say with certainty that switching to a T-Mobile sim card will give you all the advanced features. I hope this helps others who might experience this problem. I've been using AT&T (in one form or another) for the better part of a decade and can now honestly say, AT&T sucks.
Is your download speed throttled?
I use TING (a TMO/Verizon MVNO), and upgraded both of my phones to their new "FLEX" plan which came with new "Tmobile X3" sim cards and it pretty much rendered both of my V30 phones useless by removing their VOLTE capabilities despite using stock OREO rom.
They told me that although the V30 is on their "compatibility" list, but don't have entries in TMO's IMS database. Basically, with the new X3 sim installed, I lost all VOLTE/WIFI calling options in my settings, AND I would FREQUENTLY miss phone calls, texts, etc:
"So from what I can find that is a T-Mobile mobile network code aka mnc that is used by dish for their roaming agreement with T-Mobile. It kinda makes sense why volte doesn’t show up as when I went snooping in the log v30 update files to find the ims.apk file it only listed normal T-Mobile and the standard mvno mnc. But didn’t list this or the sprint hybrid T-Mobile mnc. It’s possible there’s an update that can fix this for your device but it appears ting screwed you by moving you to an x3 sim and some other people are having similar issues."
I had these same issues early this year when I manualy upgraded to PIE, but because of the way VOLTE is handled on the US998 I had to downgrade back to OREO to get it back. Well, the new sim removes these options once again, even on OREO.
Anyway, ultimately my fix was to replace both of my V30 units with V35 phones, which work perfectly at this time. It's sad having to stop using two perfectly good phones but it is what it is. Luckily I was able to find them used at good prices, but I felt a need to warn the community here about my experience. The good news is I now have PIE so that's something.
I should warn you the unlock/root method for the V35 is a bit more complicated, but still not all that difficult if you go step by step.

I think you could have gotten VOLTE and VOWIFI to work by following the WTF thread and flashing a non-US998 ROM, no? @ChazzMatt ?
I wonder if this X3 SIM a Ting or T-mobile SIM card? Could this be a Ting-only issue and actual T-mobile SIM card would be fine or other T-Mobile MVNO SIM cards may be fine?
Wow! Interesting.
I've been wondering how the TMO/Sprint merger would play out, and it sounds like they are switching to a new hybrid MNC instead of the old TMO one. And of course Oreo doesn't have that carrier config.
I would think V30 Pie should have it if V35 does. Maybe it doesn't have user interface and must be controlled through Hidden menu. But that's still better than nothing.
Thank you for reporting. You should mention this in @ChazzMatt's ongoing VoLTE thread.
Edit: Chazz mentioned it there

US998 firmware has been open and friendly to T-Mobile. It has all the bands except for LTE band 71 and normally automatically allows VoLTE and VoWi-Fi with T-Mobile SIM card. I remember in another post, and he reiterated it again in this post, that he had to downgrade back to Oreo US998 as Pie US998 wasn't allowing VoLTE and VoWIFI anymore. But then, he uses Ting -- which is a T-Mobile MVNO. No others have mentioned issues like that, so I figured it was just an unusual situation where the MVNO infrastructure isn't communicating properly.
I'm tempted to think that again... unless others with actual T-Mobile SIM card or SIM cards from other T-Mobile MVNOs chime in.
As for other firmware, the AT&T H931 would be compatible with T-Mobile bands as would the Canada H933 -- BUT I don't know if you automatically get T-Mobile VoLTE and VoWi-Fi.

I doubt H931 ROM (AT&T) would give VoLTE on other carriers. And it certainly would not support this new hybrid MNC as we only have a mid-Oreo version of it.
H932 (which my wife uses on Red Pocket AT&T) doesn't allow IMS on other carriers. It has the bands alright and regular voice & LTE, just not VoLTE. I expected to move her to a Red Pocket TMO plan down the road, but if this new hybrid MNC applies to TMO broadly, even H932 may not work long-term. She is on Pie though, so they had a chance to update it.

I'm pretty sure the "X3" SIM card they sent me was a TMobile sim. They also offer a "V1" sim card which is Verizon. They sent me one of those to try as well to try but in all honesty, by the time I ported my number to it to "see" if it would work and if it didn't then I would have to port it back and go through all that hassle.. I did throw the V1 in to see if my VOLTE options appeared.. but they didn't (for what that's worth) so I didn't bother activating it.
I found a couple used V35 ULMs on swappa like new for a really great price so I had to jump on them. I notice my phones now have two APN entries.. one for wireless.dish.com and one for fast.t-mobile.com.
I also received this message from TING, "As for the OS its just a hunch I have as I've noticed some other changes in moving to the X3 that could be related to the difference in IMSI range or the way the SIM is identified by the network. We'll keep digging on our end and if we can find a solution we'll definitely pass it along" of course this was several weeks ago and I've never heard anything since. I would have loved to get my two V30s up and running without playing "phone carrier musical chairs."
At least I'm not sacrificing anything by upgrading to the V35 (other than a little bit of money). I don't regret buying them it just seems so.. wasteful LOL
V35 is an awesome phone in other ways too: 6GB RAM (vs 4GB), SD845 (vs 835). And as discovered by head-fi titan csglinux, its audio output measures significantly better than V30 - while maintaining the DSD and MQA features lost by later LG models. All with the same great form factor as V30.
And now it appears to also have more updated IMS support, which stands to reason.
I kick myself for missing it during the summer 2019 sale when Cricket unloaded AT&T's inventory of unlocked V35 for $150 (as I recall).

I have one, like new in box. The only thing is it's 64GB internal memory. The only 128 V35+ version was sold in Brazil. I was in Brazil for 7 weeks recently and still couldn't find one. Well, not that I had time to look, as we were very busy with other stuff...
But I'm too used to the V30+. My wife uses 64GB V30 and the V35 would be good for her. But I dread the migration.

Yeah that's the thing about V35: Only 64GB. And since it's an A/B device, I assume it has even less available storage than a 64GB V30. I guess if I put all my music files on an SD card it wouldn't be an issue.
I recently switched from Sprint to Mint mobile. I kept the v30+ stock while on sprint and only performed the ls998 to us998 conversion when i ported over. Works like a charm. VoLTE and wifi appear to work just fine for me.

Thank you for reporting!
Can you tell us whether you are seeing the following on your setup (US988 on Mint/TMO):
1) Menus to toggle and configure VoLTE and VoWiFi (WiFi Calling)?
2) Indicator icons on the status bar for VoLTE and VoWiFi?
3) Did you have to use Hidden menu to configure anything?
Thanks again, and in advance!
This is my experience
1) See attached screenshots. I have a persistent notification that i can't seem to hide indicating that calls will be made via wifi when connected to wifi. Also attached are screenshots from inside the phone app's settings.
2) I'm certain I've seen an indicator on top of the phonescreen telling me that an active call was either HD or wifi? For some reason I can't remember. But im certain i saw it.
3) I didn't have to configure anything. I activated over a separate phone with a live representative just to make sure port would go smoothly. No joke, within one minute it was up and running.

Do you get voicemail notifications? Pop-ups?
What US998 are you on?
Do you get a status bar notify for VoLTE.?

Thanks a lot for sharing this!
Good to see that US998 is working well on TMO (Mint in your case).
@islandfever: I'm increasingly thinking the logic is no Statusbar indicator as long as the settings are working, i.e. as long as you can make phone calls. It is still puzzling why the indicator in the Hidden menu didn't work for you.

Status bar is not as important... Just trying to find out what rom he is using now...
Right now im using the us99820h rom.
Heres some screenshots of phone use while not on wifi. Theres no notification or status bar icon, but you see it on the dialer button and in an active call on the top left. Pretty sure that means volte is working.
**edit** also - voicemails are not visual voicemail and you have to dial in for them. I believe there is a visual voicemail app that works for tmobile that would also work with mint called "My Visual Voicemail" I haven't installed that yet but might in the future.

@pjsnyc One more question. How does voicemail alert you of a message on Mint? On 20H with Red Pocket and their GSMT SIM i get no notifications . Does it give you a popup or icon in status bar?
