[Q] EE WiFI calling - Galaxy S6 Edge Q&A, Help & Troubleshooting

So I have an S6 Edge running on EE but bought from the carphone warehouse. As such, I have recently found out that I cannot use WiFi calling as that is only available on handsets that have come directly from EE.
My first question is why is this? Is it something to do with IEMI numbers of trusted devices to make sure that only known phones can access that part of the network? Or is it that they put a different software build on the phone?
The 2nd question is that if it is a software difference, do we think it will ever be possible to enable this ourselves?
I'm quiet annoyed that I was told that I could use WiFi calling by the Carphone Warehouse when I bought the phone. Apparently it is only iPhones that are on EE that can use it if they haven't come directly from EE

You will be able to flash EE software via odin when released or in the short term you could get a refund from carphone as you have been miss sold if they guaranteed you wifi calling

Assuming that it is software that enables it then yep, I guess flashing is an option unless anyone can find where the difference is in the phone application (assuming that's where it is). Maybe its just a switch somewhere....

Damn, that's annoying. I was looking forward to having that feature, my parents house is in the back of beyond so I never get signal when I visit them.

If anyone has an EE supplied device, maybe you can check your build number to see if it matches my Carphone Warehouse one and maybe identify if there's just a build difference or something on EE's side that enables WiFi calling.
My build no: LRX22G.G925FXXU1AOCV

Got my phone from EE and the build number is:
LRX22G.G925FXXU1AOCY
Is the WiFi calling option completely missing or does it just not work?

The toggle in the phone application isn't there. Not sure how big the change set is between the 2 builds, I don't know much about decompiling android stuff either or where the configuration settings would be stored. Maybe someone here can shed some light on it...

I have exactly the same issue. My phone was bought from the Samsung Store in London (Carphone Warehouse in disguise) and I have no wifi calling option either.

Have any of you guys who want WiFi Calling rooted yet?
I ask because there are some files in the CSC folder that mentions WiFi Calling being enabled and such, so it may be either missing or set to False on other models and may just need changing.

I think flashing this EE firmware should enable this feature. I'm in same boat, EE from car phone warehouse. I can test if you want but it. Won't be for a few days as our Internet is out. I'm not really intrested in this feature as i get good coverage but it would be cool to try It.

I would imagine that would work.
For those of you who do get the option don't forget to text "Wifi calling" to 150 to get it activated on EEs side

Currently downloading both the EE firmware and my original firmware (just in case) and will see what happens on my S6 Edge. I see Kies is no longer supported so I guess I should use Smart Switch to do this rather than Odin?

Need my phone this morning for some development work so will try and flash that firmware this afternoon with Odin and will report back.

I flashed it, but no extra options appeared, but checking EE's website , they say you just make the call with no signal and it will connect via wifi instead , not sure how reliable this information is....
anybody else have any luck?

I would expect you to see the toggle for it in the phone application as per these setup instructions. Did you register by texting "wifi calling" to 150 also?

Those are much better instructions. Lol. But my menu only goes as far a vibrate. But I only dirty flashed. I'll give it another go tomorrow as I've got family coming round in a bit.

Did you flash the EE baseband too? Maybe it has something to do with the modem?
Download a Root Explorer and have a look in the CSC folder in System and post what the files in there contain?

Yeah.
but there is no CSC in my system folder. Any other ideas youd like trying.
Sorry I couldn't help you guys out more. buthe like i said if you have anything else you like me to test I don't mind. Anything for this community

In the phone type *#1234# and see what the CSC code is.
There are apps in the Play Store that let you change the CSC for the device, but I don't know whether they work for the s6 or not.
It's probably something to do with CSC though. You could try copying the CSC files from an EE firmware into the System Folder, but I have no idea if this will work or not.
CSC.zip (This is the CSC folder from my System Folder on EE s6 Edge)
Root.Zip (These 2 files were in the system folder, not in the CSC folder)

Bravo. That did it. Now have wifi calling enabled. Not that I'll use it but. It might come in handy one day.
and i have no way of testing it actually functions but the option is there in phone setting now
This just needs to be made in to a flashable zip to make it a little bit easier For some peole.
P.s just realised I'm not even on EE firmware any more reflashed this morning to stock u.k. so this should work for anyone.
the amazing thing we can do when we all work together. Really do love this community . Hope this helps someone out. If it does remember to give lakobos a big thank you.

Can't make phone calls

This is happening randomly I can't make phone calls. Most of the time I can't make any calls or receive any, I cleared the storage and looked up problems about this but couldn't find any(other than doing a full flash which is something I wouldn't want to do)
I was making phone calls last night and it didn't work for a while and then kaboom! It started working again but after a while I couldn't make any calls at all.
I got this phone yesterday its the t-mobile version and its unlocked I live in ireland and my network is 02.
My two questions are:
Why is this happening? And how can I fix this?
If I switch to android would I be able to make phone calls in this situation?
Please help!
Hmm, well it shouldnt make a difference, but try installing the cab i posted in THIS thread, post 4(which will have the added benefit of auto setting up your data connection settings too)
I'd also get rid of the stock rom too, though again, theres no reason it shoudl affect calls.
EDIT - oh hang on, when you say the t mobile version, do you mean the uk t mobile version (which is teh same as all other hd2s)? or the US t mobile version (which is a different phone in certain respects)

I have the US version with the upgraded ram.
oh ok, (though they all have the same ram, it just needs unlocking on the regular hd2, its the rom that you have double of.)
give that connection cab i linked to a try, just so you can rule it out. also, i know you said you don't want to flash a new rom, but it will sure get rid of the useless stock tmo apps.
I tried the .cab file and I still can't make phone calls. It still only works randomly and I can send messages but I can't recieve any.
Hmm, the phone is unlocked to the network you wanna use, right? and it supports the right GSM bands? (Im sure ot probably does)
all i can suggest is open teh phone screen, hit menu, options, menu - advanced network - and try disabling HSDPA/HSUPA
also on phone screen - menu - options - scroll down to band - and try messing with the settings in there (GSM wcdma, and teh band frequency options)
i've got the same problem.
Did you solve it?

Connected to carrier but signal says Roaming, no APN settings, but have internet

OK guys the title explains my predicament. I live in Costa Rica and am currently with the I.C.E for any of you that may be from here. I purchased a used S2 from a guy that bought it from Claro. So the first thing I did was get rid of the stock and I flashed everything like I wanted which is:
CheckROM v6
Using DarkKnight's Kernel
I'm using the KI3 radio but I have about 20 others and none of them changes my situation (coming up)
Original info was:
PDA-KG7
Phone- KG4
CSC - KH2
NOW here's the deal, my network icon has full bars but with an R for roaming. The phone works fine, I somewhat have data connectivity although SLOW, BUT when I go to APN settings there is nothing there NOR will it let me save a new APN, BUT I do get the 3G and H icons depending on where I am, I just can't program in a new APN or get rid of the Roaming icon no matter what ROM I flash, kernel or radio combination...
I have tried automatically and manually selecting my networks also, no dice...
I have of course already gone to *#*#4696#*#* and changed settings and tried all the variants but currently have it on WCDMA preferred.
I have also gone to *#2263# and tried all those variants but left it on WCDMA All Channels.
So I am more than open for any suggestions.
Go to Sammobile.com & search for stock firmware for your country/carrier (or just your country if they don't have any carrier specific firmware for your region), flash this firmware via Odin following whatever instructions Sammobile have for firmware downloaded from their site.
Once you've done that, check your APN setting & see if you have full connectivity. If for whatever reason your APN settings are blank (if you only end up downloading/flashing a country specific firmware only, for example), call your carrier for the APN settings and then enter these manually.
First thing you do when you have these problems is go back to stock & see if you can reproduce the problem or whether going back to stock fixes same

Thanks alot for your response MistahBungle.
Well on stock firmware is where I originally have the problem, that's the reason I began flashing ROMs and radios. IF I use a SIM from the original carrier which is Claro then all is well. BUT if I use a SIM from one of the other two carriers then the phone signal says roaming and I can't save any APN settings, no matter if I'm on stock firmware or any of the other ROMs or radio combinations that I have tried.
OK. Looks like we'll have to dig a bit deeper
So do you have baseband & IMEI in settings/about phone ? That issue of not being able to save APN settings with those other carriers sounds to me like a SIM or network issue. My first thought was it's a problem with the baseband, hence I suggested to flash a stock rom. But if that was the issue, you probably wouldn't be able to enter APN details for any sim/carrier.
Actually, now that I think about it. You know what it sounds like ? That the phone is network locked to your original carrier. That would explain everything.
If your phone *should* be locked (like you're on a contract where you only 'own' the phone at the end of the contract, etc), then I guess you can either pay the original carrier to unlock it. Or you can try one of the many unlock methods you can read about on here/apps you can get on the Market. Or if it shouldn't be locked yet it is, maybe ask the original carrier to unlock it.
You could also try flashing a specific rom for one of the other carriers, but I'm pretty sure that phone is network locked.

Ok just to clarify... all that makes sense, but what is ODD to me is that I don't think the phone is locked... I have full phone capabilities. I can make and answer calls, send texts, I even have full internet capability (even if I can't save any APN settings and there are none to be seen in the menu to choose from), I have the full speed of what I'm paying for from my carrier... the phone just won't let me SEE what APN settings it's using and in the signal it says R for roaming, but in networks it shows that it's connected to MY network...
Yes my IMEI does come up, BUT when I try one of those unlock apps I always get the message that it was unable to unlock it, but it's working with my carrier.
Ahhhh. OK. Yep that's a bit clearer now
OK. So we're pretty sure it isn't locked. That is really weird that it won't let you enter APN settings (regardless of which rom you're using), but you still have internet connectivity. Again, showing your network as the network connected to, yet showing up as roaming on the taskbar, is weird.
I've gotta say I"m pretty much stumped then. Haven't read a similar situation on here in the 4 mths I've been following the Q&A section of the board pretty much every day. Sorry I can't be of more help
Hopefully someone better qualified that me reads your post & can help. If you don't get a reply in a day or two, give it a bump.

Hey don't apologize, as you see no one else has ventured to give me a response either and I'm completely stumped myself. I looked for 5 days for an answer before I started a new thread because no one will go off on a noob for not searching quicker than I will, but I just haven't seen anyone with a similar situation on any forum anywhere...
THANKS AGAIN!!
Now to the rest of you devs, come on help a fella out and tell me what files I need to be looking for or modifying
Ok MistahBungles I got an update for ya... I decided to download a different firmware package (the PDA and Phone match mine but not the CSC), it's for Claro Argentina, BUT the ROM isn't branded when I booted it (the ROM the phone came had a CLARO boot logo (another reason I started looking for a different ROM)) and THIS ROM automatically has my APN settings in the menu without me doing a thing and the R in the signal is gone....
So now my question is how do I go about flashing the ROM I wanna use which is CheckROM but not lose my new found freedom (I ask because I'm not sure if this is a simple radio issue)

The Phone maybe Network Locked.(Not sim locked) As taken from gsmlocker.com:
Q. What sorts of locks are there?
A.
- lock phone to SIM
- lock phone to OPERATOR (network lock)
- lock phone to CODE (product lock = offer lock)
If your phone is locked to the sim you cannot use any other sim than the one you have: SIM broken makes phone useless.
If your phone is locked to an operator, you can use any SIM from this operator in your phone. You can switch between contract and prepaid as you wish, but not to a different operator.
If your phone is locked to a code, the phone checks a special "password" (GID) on the SIM that must match your phone. Providers often use different passwords for contract and prepaid.

OK I get your point BUT the phone if fully functional, I'm using a SIM from a different carrier, I have a data connection, make and receive calls, the whole nine yards, it just won't let me see what APN setting it's using and the R symbol is in the signal... once again, IT IS allowing the use of a different SIM from another carrier
Yes its the same as me! I have the R showing as well.(if you put the Claro sim in the R will disappear yes?)

BREAKTHROUGH... I think that I have found the culprit... since I live in Costa Rica I use Market Enabler... apparently whatever it changes is causing the problem, which is weird because I have 3 other android devices, I use the same app on all of them and don't have this issue... NOW I'm really scratching my head... guess I need to contact the dev?
Ahhh. So Market Enabler is changing the CSC which is causing the network settings to disappear/barf.
Nice work finding the source of the problem Yeah tell the dev. Hopefully they can find some sort of fix/workaround so you can still use Market Enabler.

Well I just through and installed and tried ALL the market unlocking apps and they all apparently do the same thing and causing the same result, my phone thinks it's roaming, so now the head scratcher is why my other Android devices don't behave in the same way? This is my only Samsung. The others are Dell Streaks.

Sorry to bump this up, but I'm having the exact same problem. I was wondering if you ever figured out how to fix it.
I have a HTC Sensation and it happened to me right after I upgraded my custom kernel version to a newer one.
I never installed Market Enabler nor Market Access but when I check the SIM info it shows incorrect MNC and MCC values which
I can't change... they won't save in the system options.
I thought maybe my SIM card is screwed up, so I'm thinking of getting a new one from my service provider.
I just have to check it on a different phone first.

No mobile network but data works

Hi all,
So my friend has a galaxy s 3 and he's not getting service so I said i'll take a look at it.
So i rooted it and changed roms and stuff and I put my sim in and add the apn settings of Giffgaff and
I got data connection H+ but then I tried to make a call and it says No mobile network phone.
I checked the imei and doesn't appear to be corrupt and I checked *#0011# and it said IMEI CERT = Pass.
So don't know what the problem is and the phone is sim unlocked .
I checked online to make sure that the phone he gave me wasn't blacklisted or anything just in case lol
Thanks!

Must be hardware failure then..If phone is not stolen/blocked different stock software doesn't work imei is intact apn settings are ok and patched modems kernels not working than all options are pointing to some sort of hardware failure.

Getting a H+ signal is different from actually getting a working data. Try to check if data is really working (browsing etc).
If there's no data even with the right APN, means the phone is probably black-listed from the carrier or you need a new (patched) modem. The right modem will solve this issue if it's not black-listed
If the data works but no phone calls, means you can try to flash stock rom and see if the problem persists.
If you were on 4.3, don't flash to 4.1.2 btw
PS: There have been a lot of refurbished/refreshed Sammy phones on the market. Their hardware issues are well known like bluetooth stops working etc etc. So if he/she got a refurb, then probably hardware issue as well.

Data sometimes works even if the phone is black-listed depending on the carrier and their implementation policies. Wifi always works though.
You mentioned changing roms.
So which rom are you currently using?
More questions:
Can you try stock 4.3 for your device/carrier?
Are you using the same telcom operator (carrier)?

I am looking for the same solution. You have achieved it?
I have the same model and I can't get the code to work in the stock dialer. How are you guys getting to open up?
Thanks

Same here. If you just want to access the network settings you can download an app like "ForceLTE" or similar.
I'm facing the same problem, I am appreciated if anyone have the solution?
Check your carrier and location
Whether you can use VoLTE or not depends on a few things:
* Your location, your account with your carrier, and the model of your phone.
* The carrier, carrier account, location, and phone model of the person you're calling.
* Some carriers support VoLTE only in certain cities or area codes. Contact your carrier to ask about your area and account.

Thanks for your reply, the problem is I have no problem to have VOLTE by using Galaxy S10 with same sim card and I couldn't find the volte "switch" in the oppo UI and couldn't turn on/off. As a result couldn't use the VOLTE function. Therefore I do think it is the firmware problem from Oppo.
I just thinking about if I could flash the official Taiwan rom of same global phone model to my current one for solving the problem. But I'm not sure if it is workable or not.

Ah. I have CPH1919 (UK) and only option is call over Wi-fi. There is also no way to get to the hidden service menu either like in every other phone I've had.
If you know for sure that Taiwan firmware has it, then I suppose, in theory, it would work providing that it is also definitely CPH1919 - any other variant has different partition structure. Be careful. Read around and let us know. Good luck
I have a CPH1919TW, it's using the same global firmware as CPH1919EX (even Oppo TW provides CPH1919EX ROM for download), the phone will ID itself as CPH1919TW.

May I know if your phone have the VOLTE enable switch in the network manual?

Unable to connect to my mobile network

I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

Thank you so much for your reply. I looked through the software section in the about section. I found the following codes about the rom.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
