[Q] Note 4 internet/call issues

Hi Guys,
I just adquire my Note 4 from a friend and i'm having lots of problems to conect to the network in my country, i live outside of USA (Dominican Republic), somethimes it makes and receive calls, somethimes i don't receive any calls but can make it but when i make it the other person can't listen to me (i've tried with diferent phone numbers) also the internet 4G/LTE is no consistent. In summary, i'm having lots of signal\internet issues with my Note 4.
My question is, is that a hardware issue or i need to try with other baseband or modem to fix this?
please give me some light as i'm losing my mind with.
thanks in advance...

I would first create a new apn specific to your carrier...
Then i would check to see if in fact your running the latest modem for the device..
But start with the apn...

Thank you for your help @Flashvetrin i checked the APN and it is correct, my modem is also the latest available UVU1ANK4 (not 100% sure did not find any other on internet) for t-mobile stock rom, some say this could be internal hardware problems but i dont think so because the phone make some calls and internet works sometimes but is not consistant.
i made a hard reset and i worked for some minutes but lost signal and went back to this behaivor again.
really don't know what to do now..
thanks in advance.

Can you take the device in for a sim upgrade???? Does the device recieve stronger signal anywhere in your area???? Interesting how your saying that after a hard reset it helps..
Try using short cut master from the playstore use #2263 launch0 and run 4 thru 8 ....

It is most likely coverage problem. My understanding is that biggest cell provider in DR is company which uses cdma technology. Do a little research which gsm provider has better coverage in your area and if lte bands used are compatible with your note4.

I've done all of the steps you mention and nothing gets better, it just works when he wants (most of the time it donesnt). I will try installing a ROM just for testing purposes.
I changed my SIM card for the newest LTE capable one. @darekz im on Claro and they are GSM\LTE.
Thanks in advance,
Miggs

I did do quick search and appears that claro using lte band 4 which is supported by Tmobile note 4. Just to check can you disable lte in phone settings and see if daya transfer improves over 4g. With poor lte coverage phone will constantly fallback to 4g and keep looking for lte.

I have changed all the different options and nothing. I have a friend who has the same phone as me and we interchanged SIMs cards and my sim worked very well on his and her SIM did not worked on mine. Im not sure on how to update the baseband but i will try to do this and to see if this fix the problem.
Thanks in advance.

Mirror the apn.
And look in her build prop as well and see if theres anything under device= that you can mirror....

Hi @Flashvetrin,
The baseband is K4, i flashed the NJ and it keeps almost the same behaivor, i can say K4 is a bit better as at least i can make calls, no calls with NJ.
build.prop, i dont know how to edit it and i'm note certainly sure about it as it can brick my phone.
Let's assume it's a hardware issue, is the hardware in charge of control the siganl interchangable, can i buy it on internet, or is my phone destined to be a clip for papers??
BTW, i installed another ROM and it's the same, no way.
Thanks for all your help,

Question what was the behavior of the phone like when it was in the us????
Fyi there are things that can be changed..
(ALOT) of things in the build prop..
your phone wont brick....
I promise..
But if your not comfortable i understand.
It may be that the modem hsic just isnt or doesnt respond on "this" paticular network..
The phone that you compared it to was it purchased in the us as well...
If its infact an International Version it may have some bearing.....
No its not a paper weight...but i am starting to run out of ideas/solutions...
Please be paitent.. im gonna consult some else as well..

The phone is the same, a TMO Note 4 bought in US and taken to DR, that's why i say this could be a hardware issue as my SIM worked very well on her phone.
I will try with other baseband and let you know.
Thanks.

Is your unlocked N8 provisioned for VZW?

I just got off the phone with VZW. My HD calling, video calling and visual voicemail isn't working. Not sure if the CSR was right, but she said there is an advance calling setting on the VZW N8 that I couldn't find on my unlocked Sammy N8. I have seen it before on my S8+ so I know What she is talking about.
I said maybe mine isn't provisioned correctly. She said she wasn't sure. I am going to call back tomorrow to speak with tech support.
You guys have that stuff working?

HD calling is using the phone while on the internet? My HD calling works fine.
I don't use video calling or visual voicemail.
I have an unlocked note 8 from Samsung and Verizon is my carrier.

I would go on Verizons account page and remove and readd the feature. Then reboot your phone to see if it works. I have unlocked N8 and Unlocked firmware running on my S8+ and the option is present

You don't have those features because you have unlocked software on your phone. The unlocked software loses carrier features. Once the Verizon software is released, you can flash the verizon software with Odin to get Verizon apps and features.
The difference between Verizon and Unlocked phones is the software.

This is crazy, Sammy said unlocked is fully compatible with VZW. Killing me!!

To make matters worse, NFL app isn't supported so no live games. [emoji24]

I think your best bet is to either find someone who is willing to swap with you their VZ variant with your Unlocked version. Or I would just change firmware to VZ version. Updato already has the VZ firmware, just flash away.

This HD voice, are you saying the call quality is horrible when talking to someone without this working? I have an Unlocked phone coming to me soon and I am also on Verizon.

It's not horrible, but I have come accustomed to HD voice clarity. So it really makes a difference to me.

This was the specific reason why I went with the VZW variant. I had an unlocked Moto Z and I dl'd the NFL app. Didn't work.
VZW tech support said that its a locked app to phones from the carrier. Any unlocked phones lost this feature and others. SUCH A PAIN.

I had an unlocked pixel xl and everything worked fine.

This may help for people looking for video calling
https://forum.xda-developers.com/galaxy-note-8/how-to/guide-to-enabling-video-calling-t3670523

I promise that I'm not trying to be rude here. But what did you guys think you were buying when you bought an unlocked phone? It's carrier unlocked. Which means it comes without carrier software. With that you may also lose some carrier specific features. But it also works with pretty much any carrier. So you can switch carriers and take your phone with you.
Personally, I never experienced a difference with HD calling. I also never used video calling. Wi-Fi calling is the only thing if kinda like to have back. I've seen some people say they've found ways to get it back on other phones. I'm not sure what those methods are.

Did you have your sim inserted when you first booted up your phone by chance? On the s8 I had this issue because I didn't have the sim in during first boot. Had to fact reset with sim card in place to get properly provisioned.

What do you mean by provisioned? And how did you get the visual voice mail app
?

I switched my Verizon line from my V20 over to my Unlocked Note8 yesterday afternoon and have no issues that really bother me. When I called the Verizon number to swap phones I asked about WiFi calling, VoLTE and HD calling and the representative told me all of these are enabled and should work properly even though the phone is Unlocked, we checked and we just couldn't find the WiFi calling setting in my device to see if it works. I have never used WiFi calling and really don't care about it, when I make a phone call everything sounds nice and crisp so I assume HD calling is working fine and VoLTE also works great. I did have 2 questions though...
1.) In the My Verizon app it keeps telling me I need a code to access my account? (see attached)
2.) When I get a voicemail, I have no notification. Is this because the "Visual Voicemail" app doesn't exist? Is there a workaround for this?

I used pf voicemail plus to replace my visual voice mail and that works fine

Video Calling Missing on Sprint

Yes, I searched the Sprint Note 8 forum. So, I have a buddy with a T-Mob Note 8. He tried to video call me. Nothing happened. So, I went looking for the N8 manual. If you get the manual from T-Mob or VZN, they show an icon of a video camera on the dialer screen, to the left of the call button. We lucky Sprint customers have our vm icon there. WTF?! Are we the onlyN8 owners that can't do video calls? Is this because we don't (yet) have Sprint's version of "VoLTE?" Do any of you who bought an unlocked N8, running on Sprint, have this problem? Thanks for any light you can shed on this problem.

I don't know but the more time I spend with a stock note I think I could do. Perhaps my first non rooted phone since flip phones. Still got time to make the change top Verizon or AT&T... You know and actually have a useable network...

Actually, maybe T-Mob? Or is that like jumping out of the frying pan and into the fire?
I actually think you're right. This phone is great without rooting. Perhaps if we get the U version of software available for the Note 8, that might be worth flashing.

I'm trying to parse your dilemma here.
Video calling works just fine depending on what video calling service you're trying to use. There's a myriad of them out there, WhatsApp, Facebook Messenger, Hangouts...just to mention a few.
As far as i know, there's no native interoperable carrier-to-carrier plain-jane video calling (like native SMS, for example).
Just saying "video calling" doesn't work, or that your T-Mobile buddy couldn't video call you doesn't tell us much. Was your T-Mobile buddy using any of the aforementioned video calling apps/services?
I video call family on 3 continents using either WhatsApp or FB Messenger (on iOS and Android) just fine.

My note 8 came with google DUO. I thought that was androids version of Facetime.

I guess you can refer to it as such, although Hangouts predates Duo. But for you to "Duo" someone else, they have to be using Duo as well.

If Sprint included its own video calling option, I imagine it would only work with other Sprint users, anyway. Just use one of the many video calling apps that your friends have and can use.

Weirdly that call had to begin on Wi-Fi and it would be a seamless transition to cellular data right?
Apparently the note will get that same feature, but who's to say how long until it does?

Wow, and here I was thinking XDA members were smarter than that..... Just so you'll know in the future : each carrier's network varies depending on your location. That's right! How they perform in your town isn't the same as how they perform everywhere else in the US!
Where I live, just outside of Atlanta, Sprint is has the best coverage and fastest speeds. AT&T and Verizon are gradually improving, while T-Mobile is still a joke.
The more you know....

Sprint will update for VoLTE as soon as available like they did for S8 but Sprint does not have built in video calling like T-Mobile...after trying to force the setting, it still doesn't work because there is no app...with T mobile, there is a hidden app that links to the setting...Google duo, hangout, Skype are the only options so far

I have an unlocked sprint phone, looking at the dial screen, the button to the left is for sms. I believe this is one of the many things sprint has never supported.

The Note 8 feature for Sprint Video Calling is still unavailable and Sprint customer care had no answers for me! The video caller icon should be on the dialer not the voicemail icon

Sprint does not hasve video calling they include duo

That's what the issue is...the video call feature is a phone feature that allows you to video call other galaxy 8 owners...however its been disabled by Sprint when you buy a Note 8 from there network...

So it seems like RCS and video calling doesn't work for U1 devices on ATT , T Mobile or Sprint. Just WiFi calling works.
Would be interesting to find out if flashing to the appropriate U firmware enables them or not.

No dice. Tech support will send me a new sim (also 5G enabled sim hehehe) but currently my number is already registered with my old Note 4 and everything works except video call and advanced messaging.
Does anyone here with unlocked/non-ATT branded Note 9 able to get the Video calling and advanced messaging to work?

My research concluded that the unlocked usa devices don't have video calling or RCS messaging enabled with any carrier.

Those with att branded ones can u pls post this screenshot
Dial *#77467#, click "IMS registration" then "ATT VOLTE"
I'm interested on what "Services" say
Thanks

Thanks! So that's where the difference is

My test results:
IMEI filter is disabling the provisioning on the non-ATT BRANDED phones.
What I did:
Put sim card on ATT branded phone, in this case an old Note4. Wait few minutes..
Try video calling wife.. it works!! Try RCS, worked.. well, this is an Att-branded n4...
Pull out sim, put it on unlocked Note9, even with ATT fw.
As soon as you have cell signal, do a video call.. IT WORKED!!
Wait a few minutes for provisioning to kick in.. phone will report IMEI to ATT. ATT finds a non-ATT branded n9, and will disable the video calling. Video calling now fails
So while phone has not yet fully registered in IMS, video calling worked. As soon as ATT finds out it's a NON-ATT phone, the extra services will stop.
So basically, they do filtering on their end. ATT level 3 tech support is clueless on what I was talking about. So there you go, no dice here..

So while phone has not yet fully registered in IMS, video calling worked. As soon as ATT finds out it's a NON-ATT phone, the extra services will stop.
So basically, they do filtering on their end. ATT level 3 tech support is clueless on what I was talking about. So there you go, no dice here..

How about with stock U1 firmware, do the features work momentarily?

Unlocked Variant TMobile band 71 and WiFi Calling Support

Does anybody know if the Unlocked version will support these features. They were sold out of the TMobile one when I went to order so I went unlocked. After contact with a few reps from TMobile and Samsung they seem to have no idea what will actually work... So I have a hard time believing what they say. Band 71 was a big selling point for me on upgrading and I hope I didn't make a mistake going with an unlocked device.

I order the Unlocked Snapdragon for T-mobile and all usa bands including 71 will be there as far I as can tell... We need to get our hands on some of these for testing.

The s9+ unlocked supports it so I dont know why the s10 wouldn't

My only reason for concern is that Samsung and Tmobile are giving me information stating it won't, they (Samsung) even told me WiFi calling won't work (even though it shows it will on the samsung support site)
I read that all of this worked fine on the s9, it just seems odd that they are saying it won't... especially band 71.

Just got my s10 plus and I see no options for wifi calling or volte. Me thinks I should have gone with the T-Mobile carrier brand. Anyone know how to flash a T-Mobile firmware to an unlocked Galaxy phone?

My unlocked definitely has wifi calling. It will not allow me to take a screenshot due to security in that section.

Where are you looking because if your looking in settings for wifi calling your in the wrong place. Open the phone app and look in its settings. At least that is where it is in the s9+ unlocked

My S10 unlocked on T-Moblile has wifi calling but not VoLTE. Bkeaver is correct that you need to open your phone app and check the 3-dot upper right corner menu for the wifi calling setting.

Welp, do I feel like a complete noob. Thanks I do see it now. Now just need to remedy Volte.

My unlocked S10e has WiFi Calling on T-Mobile. You may not find settings for VoLTE settings, but it works too.
When I first put my sim card in, the phone told me that it would restart to setup a carrier. It did, then I saw that quick setting panel added new button "wifi calling" and I tested it right away, including VoLTE

VoLTE works too, I just can't find settings, but it is enabled by default on my T-Mobile sim

Based on Charkatak's post, I searched and found the following site: https://support.t-mobile.com/docs/DOC-4988 which says in part: VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network, and it's available nationwide. Placing a call connects twice as fast.
Switching between 4G VoLTE and Wi-Fi Calling does not drop a call. So I tried placing a call without wifi using LTE and switched to wifi. The call stayed connected. Hoping this indicates we have VoLTE.

Someone correct me if I'm wrong but I believe you can test VoLTE by making a call and then checking which antennas you're connected to. If you are only on LTE towers you should have VoLTE enabled. I did this test and it seems to be working for me.

Can confirm VoLTE and Wifi Calling works fine on T-Mobile with an unlocked S10 with Snapdragon.

Yup. VoLTE is voice over LTE, so no need to involve wifi. Devices without it simply fail to connect, or switch to 2G/3G automatically (when available).
Samsung has a compatibility chart, and VoLTE was already listed for tmobile.

Excellent news! :good:

I think I already know the answer, but I'm throwing this out there: the unlocked version doesn't come with the native ability to do multi-line for DIGITS. Clearly specific to the U firmware for T-Mobile. Has anyone happened to see a fix for this...like a T-Mobile CSC for S10, or something?
I mean, the DIGITS app still allows me access to my second line, but I'd obviously MUCH prefer the T-Mobile integrated solution in the dialer.

Yes the unlocked version absolutely can do digits. It is not specific to the U version. I have the unlocked version of the s9 + and had digits going for my Galaxy watch with no issues.

Does Digits just use one phone number for many lines? Like having a LTE Watch?

I'm not sure what you're asking. Yes digits allows multiple numbers to be connected to 1 line

I went to TMobile yesterday to setup my new Galaxy Watch. I guess They set up Digits to my line #, but gave me a new number for the watch line at $10/mo. They told me I don't use that new number, and it's only for the main# to forward to..
