RCS messaging for U1 on T-Mobile?

I am running unlocked firmware on the T-Mobile network, which I prefer over T-Mobile firmware for many reasons. The only feature I feel as though I'm missing from the T-Mobile firmware is RCS messaging. Does anyone have insight on how that could be activated on the unlocked firmware?
Thanks in advance!

You need to be on the T-Mobile CSC, basically no way to do it without being on T-Mobile firmware.

Flash the newest TMO CSC and CP it should be under cloud and accounts in settings 'multi line settings'

If you do that, won't it return the T-Mobile boot and disable smart call, effectively restoring T-Mobile firmware? I believe that's the case, and if so, not worth it IMHO.
Thank you, though

Just flash the G955U1UEU1AQG2 Firmware and keep the Tmobile modem. You then have an unbranded phone with RCS and smart call. I got to keep my video calling, though from what I read, your mileage may vary on video calling.
the thread I followed Here
Unless I'm reading you wrong and you're not using a Tmo S8+.

What do you gain by flashing back Tmobile cp/CSC?

I did exactly what others are suggesting a few weeks ago...flashed the U1 XAA firmware and just the TMB CP file. While most everything worked, RCS did not, and in fact I couldn't send/receive MMSs from my girlfriend who also has a TMB U model. I had to flash the TMB CSC to get it all working again, which yes means you are then stuck with the T-Mobile splash screen and you no longer have the native scam blocking, and at the same time the T-Mobile Name ID app for scam blocking doesn't work, That being said, you can still use dialer codes to get T-Mobile's scam blocking to work. It's not the native Samsung s**t, but it works.
To enable Scam ID or Scam Block and check their statuses:
#ONI# (#664#) – Enable Scam ID
#ONB# (#662#) – Enable Scam Block
#OFB# (#632#) – Disable Scam Block
#STS# (#787#) – Check Scam Block enabled status

Thanks for that! Yes I tried the above too. No RCS unless on T-Mobile firmware (flashing CSC counts as the same!). Unlocked/unbranded firmware isn't worth giving up for RCS and video calling imo!

The rcs messaging was working for me with Samsung messages app, but I recently got a android wear watch and it wanted me to use android messages (Google's messaging app NOT Samsung's) and rcs doesn't work? I guess that's just part of it?
I can not long see the other person has read the message, or when they are typing while I'm using Google Android message app.

Verizon Advanced/HD Calling on Unlocked S9+

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.
Thanks for the info!

Whatsapp and Duo appear to support video calling over WiFi

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.

My S9 does not show LTE or 4G. I think there are a lot of bugs still.

Yes - unlocked on Verizon.

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

Enabling Cricket Wifi calling on 960u1

Hi,
I am trying to get the wifi calling option to appear and work on my 960U1. Here is what I've done so far.
1. Utilized Odin 3.12.3 (not patched version that I've seen on some forum posts) to flash AIO firmware G960U1UEU1ARBG (which i'm pretty sure is the only cricket CSC from updato.com, Sammobile has nothing listed for AIO )
2. During flash I made sure to select the CSC (not HOME CSC)
3. The flash looks like it was successful and the phone was automatically factory reset.
3. I am still missing the wifi calling option (i checked both settings-> connection menus, and the Dialer. I also tried making a call in airplane mode with wifi and it said i needed to turn on cellular.
Does anyone have any ideas what I need to do? Only thing I can think of is I'm missing a firmware or I need to change how I'm flashing the phone.
Here is a link to the cricket website saying wifi calling is supported on the S9 https://www.cricketwireless.com/sup.../wifi-calling/customer/compatible-phones.html
Thank you

Update:
So I was realized what I was missing was the AIO (Cricket) User Data. Once I located that and flashed it along with the Firmware using Odin I know have the Wifi-Calling button added to my phone. Now when I attempt to turn it on wifi-calling I get the "Please try again later" message.
I contacted Cricket Wireless Chat support, told them I have a S9 with cricket Firmware and they asked me to provide the IMEI, when I provided the IMEI they stated that it was for an unbranded S9 and that I would be unable to get wifi-calling to work on their network because of that.
Does anyone have any ideas on how I could get them to authorize my phone to get access?

It is not going to work no matter what. You have to be using an iPhone or their Cricket Branded Android phones.... -_-

Even if Crickett wanted to, their agreement with AT&T would probably prevent it. Even AT&T requires an iPhone or one of their branded phones for wifi calling. You can give up this fight.

If you had another Cricket branded Android that is wifi calling capable you could have them hard set that IMEI in the system, and that should get your S9 working.

Thank you,
I've considered this option, but now I'm weighing another consideration. It looks like mobile hotspot is disabled on the cricket firmware with user data. So unless I pay for the service maybe i should stay on a generic firmware so that it will give me mobile hotspot vs wifi calling...

\Again, FYI and maybee everyone already knows this.
The idea behind the "unlocked" handset and Android was that each carrier would have its own app to use for these handsets to enable these IMS features. As usual, the wireless US carriers have perverted the concept to tell then end user to f*ck off because you did not pay a premium for the carrier branded/bloated handset.
Man....MINT SIM is looking good.

Just FYI, Wi-Fi Calling will work fine on U1 flashed to Cricket's firmware. You just need to provision your SIM card for Wi-Fi Calling, to do that you need to insert your SIM into iPhone (SE or 6/7/8/x) and activate Wi-Fi Calling on that phone and test it out, once you see it active - remove SIM card and put it back to your S9. After you put the SIM back into your S9 - do a network settings reset, after that the Wi-Fi Calling should work. This is how I made my S9 work. If you don't have anyone to borrow iPhone from - go to your local Apple store, buy one then return it next day

Where did you find the User Data file? I've been looking high and low and just can't find any. Thanks

Also would like to know where you got the UserData.

I've been attempting to get this working on my ATT (carrier unlocked) S10+, but since Cricket only supports the S10 (not +) I'm unable to find an appropriate userdata. Do I have any options?

Wifi calling will work on non cricket device under one condition. You activate wifi calling on a cricket device. With your sim in it. Then put the sim in your phone. I also flash any multi csc firmware. And place cricket sim in the device so it auto personalizes. so then you have cricket firmware so to speak. I'm using a g950u xfinity right now on cricket with bit 7 even though cricket has only bit 6 out. And he calling and wifi calling work great

This is not true

Will flashing my unlocked T-Mobile S9 to ATT firmware allow me to use VoLTE?

And WIFI calling?
I had read in a few places this might work. I'm also not able to sync my Galaxy watch to send texts and make calls through my phone's phone number with numbersync. I'm hoping flashing the actual ATT software might fix these problems.
Any thoughts?

well, the worst thing that could happen is that it doesnt work and youd need to flash your other firmware back on the device

I flashed my unlocked cricket S9 to Verizon firmware, because I was on the U1 firmware and needed cricket wifi calling back (and cricket/att firmware downloads are mia) and when I did I got absolutely nothing of Verizon and the phone was recognized as a cricket phone. So in short basically all 0U firmware is the same the same as all 0U1 is the same. It's kind of confusing but basically on 0U your sim/carrier (even if you don't have it in at setup, it remembers the last one you used) determines your 0U for you, so I don't think what you're asking will work.

Samsung S9 Wifi Calling ROM Question

I have a new Sprint unlocked Samsung S9 SM-G960U1 and am trying to get the wifi-calling to work with Cricket Wireless. Currently the wifi calling option doesn't even show up. I was wondering if flashing an after market ROM would enable me to access the wifi-calling feature. Cricket supports wifi-calling, but only on Android devices purchased from Cricket (a note I didn't see before I bought the phone). If there is please letr me know which ROM would help me achieve this.
Thanks

Wifi calling and volte do not work on byod there is no roms for this phone. You can root but I can assure you this isnt gonna work either. All you can do is buy a cricket wifi calling enabled device

incorrect. it merely needs to be provisioned by cricket on the back end by someone who isnt the typical moron with a headset. the reason byod devices have trouble is due to the IMEI not being listed in their system and it takes a ticket to be sent to the telephony dept and have it added. They dont like doing it, but they will when pushed. Unlocked A8 and A6 on cricket both had wifi calling and VoLTE after provisioning was complete.
you also have to have the right csc on the phone.

I have a method with imei from a good cricket wifi calling phone. And have it working. But I have to give them another imei once I have it provisioned. Once their system updates with my imei I lose my wifi calling. But after provisioning I give them my actual cricket devices imei and tell them the system is still showing my byod imei they need to change it back to the other device. It works. But imei in their system is wrong.
Not imei switching or anything like that. I physically own a stylo 5 from cricket I dont use. So they think I'm on that and not my g9650. So I know it's possible just a real pain
