:crying:I'm facing some problems with my duos s7562 when using 3G connection. that is when I set the 1st SIM card to 3G (or auto) for a while it works then for no reason I'm unable to make any calls from the outher SIM and also if people try to call me the phone seems off. The signal indicator always shows good signal.
Already tried to exchange SIM cards between slots and nothing...
This means that I can only use both SIM cards in GSM mode which sucks. does this anyone else has this problem? or any hints?

SM-N950W : Mobile Data not working.

Hello,
My note 8 cannot connect to mobile data. Whenever I activate it, nothing happens I don't get any mobile data signal what so ever. I also checked the APN's configuration with my Mobile carrier and they were unable to solve it.
It should be noted that my note 8 has a stock Canadian firmware and I am using in Morocco with a Moroccan sim card

did you check with your morocco sim does include data from your plan? Also which carrier are you using in Moroccan? it could be either your plan doesn't include data plan or the carrier doesn't have the UMT/LTE band for your note 8

Yes, I still have around 1gig of data available and My plan includes data.
My service provider is INWI and they do have LTE band since The same sim card worked on my previous J5 2016 normally.
I forgot to mention that, After activating mobile data and roaming, I checked the sim status in the setting where I found that Mobile network state is DISCONNECTED and Roaming is not running.

Can you test if you can make call or text? if so, i will suggest double check the apn. I checked your carrier in Morocco , you should be able to get HSPA data connection in Canadian Version Note 8(N950W) unless you select (LTE ONLY).

I can confirm that I can make phone calls and send texts without a problem.
I checked all options and none worked .
As for the apn, the configuration message was sent to me by my service provider itself.
I performed a factory reset that didn't help too.

Since you can make the call, I don't think it is something wrong with the phone. I checked there's only 1 hspa band and none for lte available for note 8 from your carrier. I guess either double check with the carrier for the apn or maybe the phone just can't pick the b1 hspa signal from your location.

I won't mind HSPA since there's not much difference between LTE and HSPA in Morocco. I doubled checked with my carrier today and they told me that I have to wait for 48H for them to look into the issue.
The weird thing is when I used an app called LTE Discovery I found that I do have a signal for LTE band 3 yet I have no internet.
It is mostly the service provider's fault, I think.

They might be similar to AT &T where they need to recognize the device IMEI number before allowing full data access onto their Network.

I checked with my service provider. Unfortunately, they don't need to recognize the IMEI number.
They tried to shift the blame to my phone saying that I might have a faulty device. It doesn't make any sense.

First thing I'd do is research and see if it's true what your service provider told you. It might not be. Second use another sim from another network in your device. Third borrow someone else's IMWI sim and use it in the note 8. Also check APN again.
Did the phone receive 4G or LTE prior to coming to Morocco with the same device?
I also don't fully understand on your earlier post about the phone status not being roaming. It shouldn't be roaming status if using a local sim card.

I still haven't tried another INWI nor another Moroccan sim card.
I have no idea whether or not it received 4G Before coming to Morocco since I won the phone from a Dbrand's giveaway. I think it's brand new.
Shouldn't roaming be active when you activate it in menu ?
I turned on mobile data roaming and nothing happens. Check the picture for details.

I turned off my Data Roaming and the Mobile network state remained the same - connected. I'd think " Mobile network state " has anything to do with roaming being on or off unless one is roaming out of their Network onto another network.

I turn them on and off yet their status remain disconnected. I understand why.
I really don't understand how to get mobile data working on my phone.

Hopefully someone else will try and assist.
In the meantime
On the phone dialer enter *#0011# and *#2263#
Also, the mobile network state will be disconnected if you are connected to WiFi.
Should get the following screen.
Also make sure that the correct APN is entered and active / selected.
Then try and go to the connections menu and toggle lte/3g/2g... to 2 or 3 g and back to to 4g to see what happens.
Also make sure Mobile Data is turned ON.
Go-to settings then search for Mobile Data.

Thanks a lot for your efforts.
It turned out that my service provider does not support the bands on my note or something.
I tried an other provider's sim and that worked like charm.
Again thanks alooot for your efforts.

That's weird as when I checked Frequency check website with device sm-n950W and your service provider INWI , it lists it as fully compatible. The other Moroccan networks were not though.
This would be the second instant whereby Frequency check has got it wrong. First being Samsung device I used to own.

I checked the frequency myself and I came to the same conclusion.
I was only told today by an INWI agent that devices from Canada and USA always face the same issue.
I triend orange which didn't work too. Gladly, IAM worked as it is the largest and oldest network in Morocco.
From now on, I won't believe what websites say till I see for myself.

wifi calling

I got a n950U1 unlocked note 8 ( not rooted) which is a snapdragon version. I am not living in the states but bought my mobile in my holidays and was wondering how to get wifi calling on this phone. My carrier has it available as i was using it on my previous mobile, and can still use if i use my sim in iphone. I heard that the t-mobile version has it but how can i activate the setting or get an apk which can enable this setting for me? Is the app completely missing or any secret setting needs to be enabled?
Or is there a different way to enable this feature? I know that the N950F version has it but why not this one? I wasn't aware that there are differences in such options.

Also unlocked N950U1 is able to use wifi calling.
If not yet upgraded to Oreo, you can enable Wifi calling in IMS settings, using Shortcut Master app. (Search this forum for thread)
Setting will then be in Phone/Calling app, not in the general phone Settings.
After Oreo I no longer can access the IMS settings, but luckily Wifi calling remained enable after FW upgrade.

I have tried to enable via shortcut master but the app itself to make wifi calling seems to be missing. There is no setting to enable in IMS settings

I also have SM-N950U1 and I have NEVER seen or found the WiFi calling in this device, regardless of version Nouget or Oreo. I have read also a few months ago that using Shortcut maker it "should" be able to work but I also have had no success with this. You are able to find bits and pieces of WiFi calling but no actual app for it to work.

As I stated, the setting is in the Phone / calling app. In Shortcut Manager look for "WfcPref".

Not really a solution but more of a bandaid , maybe resort to flashing the t mobile firmware if all avenues have been exhausted?

I also have checked that option but there is no actual app launching, it is all tutorials or help files. I suppose it is not included within the firmware. Or maybe it is because i haven't initialize it with a t-mobile sim card. I was just hoping that maybe there is some sort of apk app by which we can have it.
This is all i get in shortcut master

Just to add also the phone/ calling app screenshot and the connections/ more connections screen

Here is what i noticed.
Note: I'm on note8 exynos csc xme
I use dual sim.
Sim1 do not support wifi calling
Sim2 supports wifi calling
I have wifi calling setting to switch it on only when i switch everything to sim2, data messages and calls.

It's restricted by 2 factors. Your telco and csc.
Obviously to have wifi calling ur mobile operator must support this and allow ur phone number to use this function.
Second is the csc of your phone. Some branded phone restrict this, they do it via csc code. U can look around on this forum there is ppl that manage to decrypt the csc files edit it and load it back. Root required for this.

Hi again,
My telco has it as i was using on my iphone. The problem is with the note 8, There is no functional app or apk for this when i do a search on shortcut master. After rooting will i be able to get the wifi calling app from somewhere after editing the csc?
Or is it much easier if i change the firmware with tmobile branded and then use my phone with it. Do you think i will get the app then by editing the csc file?
Or will it still not work as it is t mobile branded.
This is so annoying, it should have been much easier and with much more freedom, why is this wifi calling even missing as app, they already can disable if the telco doesnt support it. I never had such issue before

With Note 8 N950U1 you should have wifi calling without any problems.
Check with T-Mobile site how it works and what to do, i.c. check the requirements.. Did you put in 911 address?

Hi vash
My wifi calling is working well on sim 1 until I change this sim card to slot 2, then changed call/text and data to SIM 2,
(because I inserted SD card with 2 sim cards now, my another sim card was issued by another country, cannot get new one, so I cut the SIM 1 and moved to SIM 2)
Then wifi calling disappeared, it's gone..
Looks wifi calling will be working on SIM 1 only.

I'm sorry.
WiFi calling is working for SIM 2 as well.
Depends on the WiFi internet connection quality.

yup.. wanted to ask you to check internet connection quality. if the connection is not good wifi calling doesnt work. most of the time when i am overseas, hotel wifi is not good enough for wifi calling.. thus kind of useless for me.

Yes, thanks.
But probably not only internet quality, I think carrier will check some certificate or something.
Because no WiFi calling icon when I'm using the employee WiFi in office, I logon with my user name and password, and sometimes public WiFi is also not working for WiFi calling,

On the main screen click on bottom left call icon to make a call. Then go to setting on top right 3 dots down. You will see wifi calling enable or disabled. You can turn on or off. If it can help someone. I was looking everywhere and it didnt help, but eventually found it. It's not in connection and more setting like some place stated.

[RROS v5.8.5] Che2-L11 Kirin 620 - Sim Cards not detecting!

So basically I have a phone purchased from UAE which I brought to India. I am using Jio 4G and BSNL 2G in SIM 1 and 2. So here's what happens:
When I have Jio in slot 1 and BSNL in slot 2: No sims are detected
When I have ONLY Jio in slot 1 or 2: It detects it in both the slots
I also keep getting these Mobile Broadcast messages (even when I disabled every single one of them in the settings). I cannot read them because they're in a different language. THIS IS CAUSING A MAJOR SPAM ISSUE.
PICS: https://imgur.com/a/drkox
What should I do to get the SIM cards to work? I believe this is an issue of region locking or registration or something like that.
Thanks.

Sim card needs to be able to support 4G or it won't work. But you don't need to have 4G connection, just sim that's capable for it. I believe that's the problem.

Have you tried to swap your BSNL sim to 4G capable sim like I suggested. At the moment that's probably only solution, until you have confirmed it doesn't fix it or that your BSNL sim already is 4G capable.

Question Wifi calling using cellular data of 2nd SIM ?

Hello,
Does Oneplus support Wifi calling using cellular data of 2nd SIM ?
Instead of putting the 2nd sim card in a different mobile and enabling hotspot to use the Wifi calling, can I just put the 2nd SIM card in the same mobile oneplus 10 and still be able to use wifi calling for 1st SIM using the cellular data of 2nd SIM

I'm pretty sure ..No.. because you actully need a sim card in to enable wifi calling . No setting come up for the one without Sim in it.

Actually the SIM will be in, and wifi calling will be enabled, no issue here
My question: Does Oneplus support Wifi calling using cellular data of 2nd SIM or it will only work in wifi connection
When I travel I don't like to use the roaming for my main SIM card but I need to make and receive calls so usually I try to get a local sim card and use it in another mobile and open hotspot to connect my first mobile so I can use the wifi calling for my main SIM.
If I put the new sim card in the same mobile oneplus 10 will wifi calling work in the main SIM by using the cellular data of 2nd SIM
I know this is working in some other phone like google and Samsung and some time it is called backup calling
but I don't know if it will work in oneplus 10
