Unlocked S9 cannot register on Verizon MVNO?

I've got my unlocked S9 from Samsung. I have a Redpocket CDMA sim card, which works fine in a Samsung S7E and a Google Pixel. However, when putting this sim card in S9, the S9 could not get on its network. It shows Emergency calls only and "Not registered on network" when making a call.
Sometimes it shows "refreshing sim card data" and no network. When turning to network modes, it says "LTE/3G/2G" etc but redpocket cs seems to believe the right one should be "LTE/CDMA" instead, which is not in the list.
I tried various usual ways such as factory reset etc, which did not change anything.
I tried a project Fi and a verizon sim card in the S9 and they were recognized with no problem. Thus I think the S9 is not defective.
I did some searches and people mentioned S8 had the same issue too: https://forum.xda-developers.com/galaxy-s8/help/unlocked-s8-failed-to-register-red-t3736850
I am wondering whether anyone has this problem or a solution.
Will flashing to verizon firmware help?
Thanks.

I'm having the same issue with PagePlus! I just put the SIM from my VZW S6 into my unlocked S9 and when that didn't work I chatted with support to do an ESN change (I thought perhaps PP needed to do something on their end). I was told if there was no "LTE/CDMA" option that the phone wouldn't work on PP.
I tried using an app to switch between different network modes (including the LTE/CDMA/UMTS auto which my S6 uses) to no avail.
I'm tempted to try flashing the VZW firmware, but the post here makes me wonder if it will accomplish anything.

I tried that APP to force network mode too but it did not seem to work.
As an update, Redpocket customer service is really great that they moved my number from Verizon network to their GSM/ATT network, and everything works fine now. I do not want to try flashing verizon firmware for the same reason...
Too bad Samsung could not get such a simple thing right.

Can we sue them?
I faced the same issue too. Apparently, Samsung does a setting update that prevents the sim from registering for Verizon's MVNOs. I called them and they said they NEVER heard of this issue. Apparently, you all did too. I am tempted to sue Samsung for this since this could be an antitrust issue. They are preventing competition by working with Verizon and feigning ignorance.Can any of you comment on this?

I was going to go with one of Verizon's mvnos. And their SIM card would not work and I did not realize it until I spend the $40. I had to put an actual Verizon sim in my unlocked phone to use the Verizon network. So either Verizon is blocking the S9 on mvns or the mvnos don't have the updated information for the S9. Total wireless told.me it Had to be a Verizon branded phone for it to work. So I think if someone flashed the Verizon firmware on the unlocked version it probably would work.

i dont see anywhere on the post where you contacted the MVNO provider, to register the ESN or IMEI of the device.
Also does this MVNO even allow BYOD?
i remember I had a line from Cricket or Metro that had a sim card, it worked on my Nexus 5x, however inserting it to another nexus 5x, it didnt work, I had to call them to register my IMEI

Hey guys this is an old thread, but maybe this will help someone. My old Red Pocket SIM would not work on the S9, but my renewal came with a new SIM, ending in 8222-15XX (old was 8180-50XX) For ****s and giggles I put it in and it showed LTE/CDMA and verizon. Had RP CS switch my active SIM and now it works with no workaround!
TL;DR Try a new RP SIM if you are using one a year old or older.

I also have similar issue.
Where I used to get lte over voice, but no longer getting after a recent update from samsung. Using Redpocket cdma sim
Now I have lte and voice, but dont get lte over voice even though redpocket said they have enabled Volte on my line

We just added an Unlocked Galaxy S9 (replaced S5) purchased from Amazon (Black Friday sale), ordered new Sim from Pageplus (MVNO using Verizon ), called them to transfer the phone number, popped it in and the S9 configured itself for Pageplus, and everything works perfectly...

That's great news. I switched to GSMA due to CDMA issue. I will switch back to CDMA after my current plan expires.
I heard that RCS (messaging via wifi connection similar to imessage - samsung messages app supports it in pie I believe, not sure about oreo) is active in verizon now including mvnos. Have you tried it?

I tried for my unlocked note 8. For the new sim coming from red pocket, it works great at the first time. But later when I switch the sim to a GSM sim for international travel and then switch the sim back to the red pocket sim, the same problem appeared. I have to use verizon sim to get LTE/CDMA back in the emergency mode.

I think you've found the answer for those who are unable to get their existing RP SIM to work on the S6-7-8-9's running OREO or PIE. I just took a later serial numbered CDMAV SIM (89140000018821472XX), inserted it into another S8+ that I have, booted it and saw the Verizon Wireless scroll across the top. I'll chat with RP today and see if they will switch the ICCID numbers between old and new.
After countless hours looking into this problem, I tip my hat to you for the solution provided.

Try as I may, in the end it didn't work for me.

It worked for me when I flashed the latest un-branded U1 firmware G960U1 UEU6CSI1 via the patched Odin, from:
https://updato.com/firmware-archive-select-model/?record=E68EDDB6DBFB11E99E59FA163EE8F90B
I've also done a full factory reset from recovery after the flash.
I guess they must have fixed it with the latest firmware updates... ymmv

Since the August update, both of my Verizon branded S8+'s work directly upon inserting a RP sim card.

POSSIBLE SOLUTION!! (YMMV)
I had a similar problem when I upgraded to Android 10. I no longer had CDMA as a choice for Network mode. Here is the solution that worked for me:
Step #1:
Go to the phone dialer and dial *#*#4636#*#*
This will bring up a new screen
Select "Phone Information"
You will be greeted with a scary-looking screen with lots of stuff
Scroll down and look for "Set Preferred Network Type"
Select "LTE/CDMA auto (PRL)" from the drop-down
This will give you phone service... but not data.
STEP #2
To get data services, you will need to create an APN.
Go to settings/connections/mobile networks/Access Point Names
Click on add and enter the following:
APN Name: Verizon
APN: VZWINTERNET
MCC: 311
MNC: 480
Authentication Type: None
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6
I found that this APN worked for me... (YMMV)
Hope this is helpful...

are you folks still having trouble with this? it doesnt seem like a difficult obstacle to overcome

Thank you sooo much! Creating the APN did the trick.

How does pixel family manage VoLTE and VoWIFI?

Hi Guys,
Have a P3XL and it works with VoLTE fine with my main carrier - Vodafone Australia.
However, in the coming 12 months, I will be working extensively throughout the Asia Pacific.
I know previously with some Android OEMs, it was basically baked in for that phone/carrier combo, and even if your phone and network potentially supported the service, if you were on the wrong region firmware, you were SOL.
How does the pixel family manage this? Would it detect the sim card that I have and automatically configure the VoLTE if it were supported by that carrier? I know recently, via a tweet from @LlabTooFeR that some people are modifying to gain this, but dont want to resort to this if I dont need to. (Phone is rooted already though haha).

WARNING! V30 (US998 possibly others) No Longer Works Well On TMO

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.

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?

Fake phone device model to network carrier

Hi,
I own an Oneplus 7T, which is VoLTE and VoWiFi enabled. Is it possible to make my network carrier believe I'm connecting with another phone model? Like a Xiaomi Redmi 10 for instance. I need my network carrier to stop disabling VoLTE and VoWifi from my subscription. It does so because I own a OP7T.
Here's the whole story...
The OP7T has two SIM slots and they are populated as so:
SIM 1: Orange Telecom (french)
SIM 2: Bouygues Telecom (french)
Orange won't recognize my phone as VoLTE or VoWifi compatible, whereas Bouygues does. I finally got in touch with a skilled employee there who told me that this is Orange's stupid politic to enable VoLTE only on phones they sell at their store! Gosh... There are some Xiaomi, Huawei, and fo course Samsung, Sony... but no Oneplus.
When I put my Orange SIM in a Samsung compatible phone, VoLTE and VoWifi work and remain ON, forever (I tried 3 weeks). If I switch to my OP7T, the VoLTE will work for 2 to 24 hours (very random) and then it turns OFF (only for the Orange SIM).
Ok, but why do I need this VoLTE and VoWifi so bad? Because I bought a Samsung Watch LTE, whose LTE option won't work if my carrier disables the VoLTE option!
=> I configure the Watch on my crappy Samsung phone, in which I've inserted the Orange SIM, and everythings works fine.
=> I put the Orange SIM in my OP7T and the Watch's LTE keeps working some hours (also the VoLTE sign is ON for SIM 1 & 2)
=> When the VoLTE sign disappears on my OP7T, for SIM 1, the Watch's LTE stops working too.
That turns me crazy... and Orange is the only carrier to provide a LTE option for my Watch so... I'm stuck. Of course, I don't want to buy another phone, this one is new
So, any way to fake my device for my carrier? Please...
Thank you!
Edit: my thread has been moved to the OP7T forum, but it does not belong here at all. That's a general Android phone question about chaing the model presented to the carrier. So I guess I'm not going to get any answer here...

volte and wifi calling only work for the sim you have as primary data. just making sure that's not your issue

Hi, thank you for the answer, however both work for both SIMs on my mobile. Also I can have LTE activated on obth SIMs at the same time, and for example keep the LTE data on on SIM2 while having a phone call on SIM1.
My issue is absolutely the one I described, which is that my carrier disable VOLTE when it recognize my mobile as being "incompatible" (so they say)

Something like this?

Question New update for US TMo - adds eSim

Just updated this morning, we now have eSIM support (supposedly) with the second IMEI showing up in settings. I haven't tested it yet though, so ill try to later today.
Edit:
So my secondary carrier is GoogleFi, which won't recognize the available eSim. So I had to convert my physical TMo sim to an eSIM (permanently disabled your physical sim card). This allowed me to move my GFi card to the phone.
GFi app recognized the sim card and activated, however it looks like Samsung/TMo baked in a TMo network selection feature for this sim. Instead of recognizing that it's GFi with it's networks, you had to select if this card was a TMo/Metro/Assurance carrier. I selected TMo thinking that GFi uses them mostly around my locale that it'll work. However we now get the X on the signal chart.
My guess is this is the good ol network lock coming into play. So we got eSim and 2 sim cards...we're locked to TMo and Metro still. Hopefully better luck for those with Unlocked US phones

I have a Samsung version (still on TMO but not TMO branded) and got the update today with esim too

So new update: becareful with converting your Physical Sim to an eSim. I can't figure out why, and am on the phone with support, but the eSim for TMo doesn't register on the network. wifi-calling works for the eSim, but nothing else. In the Sim card settings, it detects an "unknown" carrier, whereas the GoogleFi (which doesn't work probably due to network lock) at least detected GoogleFi.
Edit:
So...whatever you do, don't listen to Help desk. They had me removing my eSim so that I can do the "scan qr" method even though I did the proper Convert to eSim method previously. The removal doesn't actually remove anything from the phone, so you can't "start over" hoping to try a different method. Even if it could, you disabled the physical sim, so you have no method of receiving the TMo verification codes needed to add a sim card to the phone. You literally lock yourself out of the network until they send you a new physical sim or reactivate your old sim
To reactivate the old sim, while forgoing the text message, is a 10min processs. Fortunately that's probably the most straight forward aspect. The 10min wait is to let the verification process timeout and it'll just activate.

I gotten it 5 days ago I really like the new features

What is esim?

Esim is where you can ditch the actual sim card and your phone have a built-in sim card manager to keep digital copies

I switched one of my other lines to my fold3 esim today (on TMO network) and been on with support for a while now they have no idea the issue. But it detects it as a T-Mobile network but it won't discover the number. It stays as unknown number. Can't use the data, calls or texts but it activated
Edit: after going back and forth with tech support, the issue has reversed itself. Now the esim has a number but no provider lol will keep this post updated
Edit 2: after more back and forth with some escalated executive support team they found the problem and fixed it. It's supposedly a bug in Samsung's esim that needs manual high level settings changed on TMOs end to fix on a per device basis

I'd like to say that after several days with physical sim and esim, I've zero problems. It just works. My only complaint is how voicemail is handled for the 2nd sim.
