Need Help Getting Sprint Network on Verizon Note 2

Okay, I'm sure the information is all out there, so before I get told to search forums or google, I have. My issue is that I'm just having the hardest time putting all the scattered information together and understanding it. There's too much information to decipher whats needed, accurate andd up to date for my situation. So I was wondering if someone whose done this before could just give me the straight to guide.
I have verizon, my girlfriend has sprint. She broke her S4. I have an old verizon note 2 that is unlocked, rooted, custom recovery and on CM11.
What I need to do is get it on the sprint network and get her service switched over to it.
I know it has something to do with APN settings, but there's so many different ones whether it's for internet and MMS. I basically just want her to be able to use it to make phone calls and maybe regular texts. I got all confused when I saw things dealing with PRL and what not, so I don't actually know which things I need to make this work.
I put the sim card from her S4 into my Verizon note 2 and opened the access point settings under mobile network. There are a bunch of sprint ones in there now, I don't know which one to choose. I tried the one just labeled "Sprint" and then rebooted to get the APN settings to switch over but I still have no service to try and activate the phone.
So could someone please give me a simplified walk-through of putting in sprint's settings on a verizon note 2. I tried flashing a Sprint CM11 rom but it failed. So now i am going to try flashing a sprint touchwiz rom to see if that will make all the necessary changes for me.
Update: I Just finished flashing jellybomb touchwiz rom, it flashed but wont get into the phone setup, says there's an encryption error and the phone needs to be reset. I did that and it still does the same.
Thanks in advance guys, I've flashed a lot of roms, I've just never switched my phone to another carrier before.

You can't activate a non Sprint branded phone on the Sprint network. Period. The esn is not in the Sprint database and even if you wanted to use the phone strictly for traveling internationally, The sim card from Sprint will not work in the Verizon phone for the same reason. You'd have to "clone" the phone/esn and that is completely illegal. I would spend my time on craigslist or Facebook and try to trade your Verizon phone for a Sprint one. That's what I would do.
FYI . Verizon phones are actually in demand due to the much larger customer base so making a trade for a Sprint S4 or Note 2 should be fairly easy. But MAKE SURE you check the ESN with Sprint before making a trade because a blacklisted esn phone can NOT be activated and you will be SOL.

So only networks like at&t and T-mobile will work on my Unlocked verizon phone?

If you're referring to your Verizon phone being a "world phone" which does in fact have a sim card and gsm network capabilities, then technically yes it would perhaps be possible to get it to work on AT&T or T-Mobile onl;y but it would be very difficult and time consuming to unlock the sim portion of the Verizon phone and hack it so that it would not be rejected by either network due to the ESN. You'd have better luck trying T-Mobile because they seem to be more lax with unbranded iPhones etc on their network. But in all honesty you would be better off trading your Verizon phone especially if it has a clear esn and getting a phone that's ready to go with no headaches and fully functional on the network.

thanks for the replies

[Q] Note 2 from Sprint to Verizon, basic questions

I got a galaxy note 2 with Sprint on it, and plan to switch over to Verizon wireless (I use one of those 3rd party companies that use Verizon lines) and I heard they don't like unlocked phones. I have a few basic questions, please note my phone doesn't have a SIM card. I like Sprint, but their coverage is more city based, and the problem there is I don't live in a city, and big red has got us covered under 4G LTE.
Will I be able to pick up a Verizon LTE service, I remember there was some sort of error with my older S3 and it roamed on a Verizon 4G network, i'd assume my Sprint note 2 can do the same, and is capable of picking up that signal.
Also, will the company be able to know I have an unlocked phone? Or will it assign me a new MEID with Verizon when I select that option, (Yes I know how to unlock, real simple process) And when I go to type in the MEID/ESN for activation, will it recognize it is on an unlocked phone, if so how do I fix that without doing anything illegal (Like changing the MEID, which is very complex, and illegal)
And will I be able to keep my current MEID I have on Sprint, if I select Sprint under the network options.
If you are confused on my wording, i'll be glad to help you out. Also if you know anything about the HTC One M7, will I be able to switch that over too, and would I also need a Verizon SIM.
Thanks for the help, I am not an expert so try not to be too complex, I also perfer to avoid CDMA tool if possible, I dread that software at times.
If there's also a way if 4G won't work to trick it into thinking I have a 3G only devise under Verizon that would be cool too. I don't expect this to even be possible without a dreadful process.

Bump, not sure if you are supposed to do this.

Unlocked Sprint S6 on Verizon?

I have an unlocked Sprint Samsung S6 and I'm trying to get it to work on Verizon but it doesn't want to work. It shows an exclamation and R where the signal bars are. I have tried setting up the APN and a Verizon rep put the sprint phone in their system, but that didn't work either. Is there any way to get this to work? Do u have to flash Verizon's Rom to it? I noticed that even unlocked it still seems to have the sprint activation stuff..... Please help, scoured the Internet and forums to no avail :/

If you actually got the phone activated onto your line on Verizon, you will need the Verizon PRL on the device for it to show it connected natively to its towers (the 'R' is a roaming indicator...your device is seeing the Verizon towers as roaming since it loaded with a tower list with Sprint towers prioritized). Verizon is still CDMA, so you will need the proper PRL flashed to the phone for it to work, first & foremost, along with your NAM information and all of the Verizon data settings flashed in place of the Sprint data settings. With regard to CDMA switching from Sprint/Sprint-based to Verizon/Verizon-based, there is more to it than merely an ESN swap (activation by an agent) & inserting a SIM.
I am not here to hold your hand through the flashing of anything, but I'm letting you know what will need to be done. These phones have different model numbers for a reason (unlike "hybrids" like newer Nexus devices, newer iPhones & the recently released Moto X Pure). These different models are designated per carrier and the bundled carrier software for many CDMA devices is used in its OTA programming. Sprint devices typically are packed with MSL/SPCs unique to the device and needed to edit the internal NAM & data settings while Verizon branded counterparts have 0s instead of uniques codes. If this is all over your head, you may need to seek the assistance of someone or a company familiar with flashing to get you going if you are hellbent on using THAT device. Good luck.

worked for me but not stable
I also have the s note 5 from sprint and been trying to make it work on verizon. After so many tries in the mobile network setting i got it to partially work. it still have the R symbols on top, which shows your roaming but you will get a 3g speed. My current setting is
Settings>Mobile Networks>Network mode >automatic
Settings>Mobile Networks>data roaming>Roaming network>automatic
Settings>Mobile Networks>data roaming>Roaming guard> all off
Settings>Mobile Networks>data roaming>everything else on
you also have to use the verizon app settings.
i've also tried flashing the prl but had no luck. Any suggestion on how will be appreciated.

So, how about an idiot's guide for making this happen?
If I need help from a vendor, how about posting some referrals, what needs to be done, and how much is fair to pay?
I am a self-professed newb and I just want to take the Sprint S6 that I own outright to Verizon.
Especially because I paid full price for the S6, and Sprint's service sucks inside my building.
Thanks .

What VicFreeze said above is 100% correct, you would have to reprogram/flash the phones CDMA chip/radio and even Verizon will not be able to do so (legally or maybe not smart enough to know how), you want to be on Verizon you need to get one of their phones. Your phone is a G920P, the P is specific to Sprint and the phone has been flashed internally to know the MIED, MDM/MIN, PRL and login passwords for their networks along with the MSL Code direct from the Samsung factory just for Sprint.
So Yeah you can change all this by reprogramming the CDMA chip inside the phone, first you need professional software that will cost $$$ hundreds of dollars, software like CDMA workshop, QPST or DFS will work, learning to use this software is not for newbies, you will also need to get the information from Verizon to flash their carrier specific codes and numbers into the phone, it's not like swapping out your SIM Card like a GSM Phone and your on a different network, this is CDMA and its why Sprint/Verizon use this, its to lock you down. (no, that's not why)(LOL)
Just Google "Carrier programming on CDMA phones"..
I think it would be cheaper to sell your Sprint phone and just get a Verizon phone and save yourself a lot of hassle. Get a G920V, its already flashed with Verizon Codes to access their LTE Network from the Samsung factory (Hence the V is specific for Verizon). Verizon's sales staff might not even know what a CDMA phone is so would you really want them to reprogram it??

VicFreeze and MindTricks sound dead on in there advice. One thing I am pretty sure about unless someone corrects me is .... even though Sprint and Verizon are both CDMA, they operate on different frequency bands which is probably why your getting the 'R' for roaming. CDMA Workshop has the ability to change the radio frequency. I think the two companies also encrypt or code their voice and data traffic and you need the software flashed that has their specific decoders or encryption software for the device to work on their system. I am not sure if the specific radio software changes any of this or not. I am not even sure is CDMA Workshop is compatible with newer Samsung phones now as two years ago I programmed my Sprint HTC EVO 4g to work on my Virgin Mobile talk and text plan without much trouble but have not been able to get CDMA Workshop to connect to a Galaxy Grand Prime as of late. What I did two years ago was easier since Virgin runs off of Sprint Service Towers. Having a ROM compiled for Verizon may help but things have changed. What I did with the EVO two years ago ..... the ROM had Sprint radio files compiled with it. I am not sure if some of those files are separated in the system now on more modern devices as ..... back two years ago Sprint was EVDO and not their LTE uses a SIM card to work. So, things have changed and keep changing and evolving. One thing is sure, is almost every year Service Providers along with device manufacturers are changing what they do and how they do it.

That's what everyone would love to do but at times proves more hassle than what it is worth. this is why there are sites like Swappa and eBay where you can sell your phone for close to competitive price and pick one up a device that is a comparable condition for the service provider you want to swich to for about a break even price or not much more out of pocket.

I dunno if this thread is dead but process should go something like this.... flash factory binary firmware checking "auto-reboot, nand erase, and F.reset" options. Once it boots enable developer options and oem unlock and usb debugging (then do a factory reset from settings menu). Then you can flash the CSC from Verizon stock. Placing VZW .pit file in appropriate section. Then you can flash the BL,AP,CP files from VZW rom. Personally....this seems like alot of unnecessary work with a great chance for missing something. Might be better to root sprint device and manually install vzw modem files, apns.conf, prl, telephony.db.....better yet why not just flash a custom rom from twrp. thats just one zip file in twrp.

I don't know what I've done differently, but I currently have and use without any problems a Sprint G920P on the nations most reliable network… Verizon. I can tell you that I didn't have to jump through all or any of the hoops that others in this post have outlined. I will tell you what I did ; Flashed G920p with Bigdaddy PL3 Aroma V1.x ,TWRP-3.2.1.0, SuperSu-v2.82, and 3.10.61_Stock_Modified_Kernel_By_Aurora_Rom [email protected]#1. Phone has been unlocked by Idonne apps. I believe that last bit has a lot to do with my success. there is a setting in his app if the phone is to be used on a CDMA network or a GSM network. And not to discredit the person that discouraged you from having a Verizon employee help you but it was he that figured out how to make Verizons system find my phone. Not sure exactly what he did but I saw him take his company phone out of his pocket and scan the sticker on the back of it into the system saying "we will just make the system recognize it". Voila, worked perfectly and continues to operate without flaw on their network. I do get a roam "R", but checking settings indicates that I am not roaming. I live on the border to Canada so it is to be expected, but not the case. As far as Network, device says Preferred Network instead of Verizon. It could say your name for all I care as long as it works! Hope this sheds some light on it for you without having to make all of those unnecessary changes. One last note.... the salesman did say that mine is the first Sprint Device that he has seen on their network.... I guess that makes me special huh? Lol...

AT&T tech support said my OP7T not LTE Compatible

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...

AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal or data, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

I'll bet if you look in the settings your model is HD1905 or the global model, not sure the number.
Actually if you could take a look for me and post back here that'd be good. It most likely won't make a difference but I'm curious.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Anyway it's BS. If the carrier supports the phone, and the phone is capable of VOLT!/WIFI CALLING, it should work.

Yes Verizon. I have heard hear many times on this site, that phones are blocked from wifi calling by the IMEI, I or they could be wrong.
Vowifi works on the unlocked Pixel, but are they going to butt heads with Google? Volte works fine, I got a network extender, and I can use google voice to make calls over wifi if I really need to.
If vowifi is a must, get an approved phone, that is all you can do.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?
I was able to get it to make calls after a refresh signal was sent out, but it could not connect to mobile data . My sim is fine. I even popped it my son's Pixel 3a and LTE started immediately.
The seller is saying the fact that it was able to make calls means it is able to connect to mobile data. And I should take it to AT&T before returning it. I don't think he's scamming. He says he has the same phone on AT&T. And he's sold Hundreds of them. That kinda checks out based on reviews and some of those people do report it works with AT&T.
These phones are hd1907 T-Mobile but supposedly OnePlus unlocks them before sending them out to some sellers. I sort of believe the guy but is it true? If it were locked to T-Mobile could I get it to make phone calls?
Obviously I'm not talking about a hack. Because I thought locked was locked. Is it possible for a locked T-Mobile phone to make calls on the AT&T network?
Also I got AT&T to make it work but once I removed the sim/reinsert it, the thing displays weird behavior. Wifi goes in and out. It forgets the apn settings that were set prior.

I agree, ATT was the most horrible experience I ever had. Tracfone may have even had a better customer support.
Verizon CDMA service may be antiquated, but their customer service and tech support is 2nd to none.

It should have no trouble using data BUT you'll have to change the phone's APN settings to match your carrier before you can. You can google it and find them. It's not hard at all to change. Somewhere under the "network" settings.
Someone correct me if I'm wrong, but as I've understood it the phone will keep trying to access the previous carrier's data network, which is why you didn't have data. But as said above the APN settings should fix that.

If I told you the whole story, which started on Friday morning and in the end involved 7 AT&T employees, 6 on the phone and 1 in the store, it'd probably be removed because it's spam. Too long of a story.
But in the end it didn't get to connect to mobile data..at least not consistently. I took it to the store. The guy removed the Sim reset it, turned it off and boom! - LTE, calls and texts. His theory was it takes a little while for it to unlock and get set so when I tried it the other night it wasn't working.
I was happy because it literally took 5 minutes. I ran some errands and was out for like another 2 hours. Everything was working. Some point between the store and my driveway, the signal was gone. I never got it back. Of course I tried reset, remove Sim, reboot, change apn settings.
I called AT&T... the first woman didn't even know what CDMA and GSM was. I politely got her to transfer me to the guy who 'knows his stuff'. He got it to make calls again, but in the end concluded this device can't work on this network. I didn't wanna argue anymore. He had a BS answer for everything including 'If it doesn't work, why DID it work just a half hour ago?'
He said I could try getting a new sim. They have no idea. My son's sim won't work on this phone but pop it in my old phone and it works. And my sim works in his phone. It's not the sim. I know it.

I took it back to AT&T yesterday. There was someone in front of me so I sat down, removed the sim from my working phone, popped it in the op7t... instant lte, calls & texts. The same thing happened the day before I went to at&t. It worked perfectly well there in the store and even 2 towns away but not m my neighborhood which DOES connect to LTE, has for years on every phone we've had.
The tech (if you can really call him that) updated the sim. That got it done. I've had a working phone for 24 hours. BUT no LTE. It only connects to H+.
I haven't had time to call or go back to the store, but I'm hoping it's an easy fix. This has been the weirdest week I've ever had dealing with a phone. I've learned that AT&T doesn't know what they're doing. I still can't believe I needed to explain what GSM and CDMA was to one of the people on the call.
I'm gonna try a few things tonight after work.

Thanks for sharing, but I've never really needed to mess around with the settings as far as mobile data goes. It either works out of the box, or at most I'll need to put the apn in manually on some custom roms, but even that's rare.
How does the info you provided apply to my problem. I know the phone can connect to lte. It was connecting briefly on Monday afternoon and while I was at At&T yesterday, it connected before they updated the sim.
Is there something I can do with this? It's a sincere question. I'm not sure if I can apply it somehow. Thanks

I think his point was to show that the OP7T does in fact work on all AT&T bands. Normally you don't need to do anything with this if the SIM is provisioned correctly.
What are the chances that you are on the edge of the local AT&T LTE signal so it drops to H+ because that's a stronger connection? At the AT&T store the LTE signal is stronger so the phone is favoring that one. Some phones are more sensitive to signals than others (or more aggressive at switching to a stronger band).
Try using a program like "LTE Discovery" and see what bands you actually are connecting to. It can also let you know what is going on in your area with tower location.

That's what I said but the guy at the store said it's really not a stronger signal at the store. Plus I know I can get LTE at my house and in the store because all our other phones connect, even this one, briefly at the at&t store.
The seller have me a code to input into the dialer but I'm waiting for tomorrow to put it in. It's my day off. If something goes wrong it won't be a huge deal. I will look into what you sent at some point though.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

Your posts are bouncing between VoLTE & VoWiFi.
LTE bands and VoLTE work fine on Verizon's network.
Verizon allows VoWiFi on the OP 8's that they sell. They will not activate VoWiFi on the OP 7 series, the claim is that the phone did not go through their security testing. IIRC VZW doesn't allow VoWiFi on any outside phone.

Cricket canceling 7T on their network?!! As of Feb 2022

I made a call and got a message that my phone would no longer work on their network since they are upgrading things. This phone isn't that old. I wonder if their system doesn't recognize it. The lady said their system was showing it was a 2g phone so I told her it handles 4g. She said on Cricket it's only able to use 3g. Does anyone know if this is true. I don't trust some operator in another country reading off a script. It sounded like they want everyone to buy phones from their website. I can't imagine a relatively new phone not having the right band. Maybe there is a setting I need to tweak or flash onto my phone if I'm only using 3g on Cricket. I'm sure I've seen my antenna say LTE. Or maybe Cricket is screening out non Cricket phones.

Check it's specs.
If it supports the needed 4G bands it may need to be reconfigured. I haven't a clue how to do that.
Maybe Access point names but it may go deeper than that.

I'm going to google and see exactly what specs Cricket will require. I think you're right and maybe something to reconfigure. I can't imagine Cricket shutting off tons of new ish phones just because they aren't bought from Cricket. Ran a speed test now and got 2.77mbps download and 8.49mbps upload. I am showing LTE now which means I'm not on 3g as she was saying now. I bet it's a sales gimmick to scare less savy folks. What mean loose phone signal in Feb hehehe.
Edit: I was on wifi when I got the message so maybe when I phone is on wifi and not using their LTE network it doesn't detect anything which is why they told me I have a 2g phone. When I shut off wifi LTE popped right up so it's probably a glitch in their way of informing us.
Edit2: Spoke to a tech at Cricket and he said my phone currently isn't compatible with them aaahahahhaha dumb. I told him I'm currently using it on LTE just fine no issues. He didn't have anything to say when I asked him since I'm not using 3g then it shouldn't affect me. He just said he wants me to have great service so buy another phone from Cricket. BS

Only HD1905 works

I have HD1907 and it's currently working on LTE. Are you referring to not working in the future or currently working?

Not working in the future. Here is the list of devices can work after Feb 2022.

Yes I was able to download that list when I googled. Judging by what it said these are phones that are tested and will work, not so much that other phones won't work. My phone was originally branded for Tmobile so I'm sure they wouldn't have tested it but it would have only had a different OS with Tmobile bloatware which I took off. The cricket people said their LTE isn't changing so I shouldn't have an issue but it will be interesting to find out. They must have just been looking at this list which is why they said my phone currently isn't compatible.

Funny this was asked but no answer given from ATT. I'll keep googling

I read a discussion here from 2019 someone else asked and the different variants are by region as they usually are for the different LTE frequencies. 1905 is North American, 1907 is Tmobile in North America so I would imagine my LTE frequency is still going to be fine. Those that bought Chinese phones etc probably not.

This is weird. The current ad for it on Amazon says it's currently not compatible with ATT and Cricket. I wonder if me flashing another OS for North America or USA I forget is why it works fine? Maybe I'm screwed hehe
*** NOTE: Due to changes with AT&T and Cricket, this phone currently cannot be used on AT&T/Cricket. Compatible with T-Mobile and all GSM Networks along with their compatible MVNO networks such as Red Pocket GSM, Ultra Mobile, Mint Mobile, Ting GSM, Google FI and many others. This phone is NOT compatible with Verizon, Cricket or AT&T. Please verify with your network to ensure complete compatibility.

I work at a prepaid carrier store (not Cricket) and am having to tell customers the same thing. It's not just about if your phone has the radios necessary, they have to have the IMEI approved in their system and if it's not then you can possibly escalate to someone who can help get it approved but you probably won't get very far. I can't activate my own OnePlus device with my company either, even though it's currently running on our parent network. I have spoken with internal support folks about it multiple times and have gotten nowhere so I gave up.

Believe it. It sucks and it sounds insane but it's really happening. For me? I have to tell everyone with a Samsung Galaxy S5-S10 that they have to buy a new phone to be compatible with our new network changes. And I can tell you here that it's (probably) not the sales rep lying to you to make a commission sale, our tools are indeed forcing us to do that.

I'm just wondering why they are saying my phone currently isn't compatible when it obviously is. It works great. Even streams HD in an instant on Crickets network. Corporations aren't super efficient at checking all things under the sun. They are just checking phones they approve. They told me the same thing that my imei currently doesn't work but it does. Unless they are trying to be like Verizon and only allow specific phones in the future I'm still thinking once they shut off 3g then when someone wants to switch from Tmobile to Cricket with their unlocked working fine non 3g phone they still can or are they saying no they are going to be like Verizon and it has to be a Cricket branded phone. I don't think it's the later. I think they are just saying what will work, but not saying what won't work. Let's find out =( hehe

Read a discussion from 8 months ago. Seems like most are fine, one guy with a 1905 had issues on ATT. One guy did what I did so maybe that's why mine is fine for now. I haven't had issues like dropped calls etc but maybe the real issue I will have if Cricket adds wifi calling and VoLTE is if they use a specific frequency and the 1907 is missing it then I won't be able to use those. If Cricket only uses VoLTE then yes I am screwed in February =/

"I am currently using a 7t that was advertised as factory unlocked on ebay, when it showed up and I turned it on the big bright pink Tmobile boot logo came by. I did some research and found the convert to international/global thread on xda, I got rid of the crap hydrogen OS that came with the "unlocked" Tmobile phone. Using ADB I was able to flash the international firmware Oxygen OS and haven't had any problems with at&t now."

If it's an IMEI issue, flashing with the hd1905 fw probably won't help matters. I have a hd1905 on cricket since 2019, everything but wifi calling works. The same cricket sim in a samdung s9+ yields working wifi calling.
So while the hd1905 and 1907 are essentially the same hardware devices, the serial #/imei may determine what happens come 2022.

Yup, I'm wondering if the hardware or the IMEI will determine things. I didn't even know Cricket had wifi calling. Did Cricket even let you download the wifi calling app but it didn't work or did they not allow you to download it?
Edit: I looked it up. Looks like wifi calling will work on phones that have it built in to their OS settings. I probably won't use it if I end up buying another OnePlus phone. I wonder if there are any phones where wifi calling is working on Cricket that isn't on the list but is in the OS settings.

Wifi calling app? The s9+ was hybrid flashed. Everything but the main OS came from the U firmware (carrier), while the rom came from U1 fw. Result was working carrier features (volte/wifi calling) without the bloat.

The s9+ is probably the same as the s9 as far as the wifi calling since "+" isn't mentioned on their list.

Huh? It's right under the s9.
