N910V No signal in Argentina

Hello everyone,
I bought a Unlocked Note 4 from Verizon in USA. In Argentina I don't have signal. We use GSM so it should work right. I know this device has not root access. I just want to make some calls or messages.
It doesn't let me search network manually. It throws an error "error searching networks"
Android Version: 4.4.4
Network Mode: Global/GSM
Somebody could help me on this.
Thanks in advance.

I am in Europe past month, leaving to us in few days and was using my note4 in GSM mode all the time and switching between carriers on a prepaid sim. I would do factory reset or maybe get a new sim.
My prepaid sim allows roaming on all carriers.

I already flash the mobile with Odin thinking that the Android version might be the problem. It still not getting signal. I'll try with another SIM card.
Did you use others GSM carriers instead of T-Mobile?

I tried with many SIMs, I flashed the device three times and I still having. So maybe there is a another issue. Please someone can help me. How is the Micro SIM should I use?

Which carrier are you using this on? Verizon has always used CDMA for 3G, not GSM. The Verizon Note 4 (SM-N910V) does seem to have limited GSM support, but it might not work on every GSM carrier.
This website seems to be pretty accurate: http://www.willmyphonework.net/

Acording to that page my phone should work perfectly
with 2G, 3G, 4G LTE.
I'm using:
Brand: Samsung
Model: SM-N910V
Country:Argentina
Carrier:Claro Argentina
I don't know what is the problem.:crying:

You may need to add new APN settings before it will work.
On mine, the option to add a new APN is disabled, but I'm actually using mine on Verizon with a Verizon SIM card, so I'd have no reason to edit the APN settings manually. Are you able to edit yours?

I already set the APN and nothing happens. I'm not sure APN could be the problem. Should be something else.

If the APN settings aren't correct, it could absolutely be the problem. It's worth double checking.

APNs
I tried with severals APN and nothing happens.

I have an Oneplus One with the same APN and works perfectly. That's why I think the APNs are not causing the problems of signal. I still having no signal. I cant make neither a call nor send a message.

Hmm sorry bro not sure what is going on.. last thing I could suggest if you have some money to spare try any other sim card from different provider or ask a friend to swap it for a minute or two,anything to test that it's not your carrier somehow not wanting to work with VZW N4.

Hey I read something couple days ago and forgot to get back at you.. I read somewhere if you block activation agent it should work some people on T-Mobile USA had the same issue. Use debloater to block activation agent on boot. They said this could be because the note could never been activated on Verizon even for 30 seconds and this is why it might be happening.
So block activation agent,and setup wizard so it's blocked on EACH BOOT.
Let me know

Well, just did a very quick research and it turns out the it does support VoLTE on T-Mobile, but I guess that statement is for the US only.
Is there any way to find out if that is also valid for the German T-Mobile and/or other networks, since we use other bands too? (I don't have the phone yet).

You are wrong. It supports VoLTE globally. I am using it in India.

I had those information from some reviews that stated it couldn't. Apperently the providers have to unlock each specific phone type to use VoLTE. T-mobile germany didn't so it yet and have currently no plans to do it for oneplus 3 nor even nexus.

I had to "enable" VoLTE on my MotoX PE (on T-Mobile USA) and I am wondering if you need to do the same... Not sure if this will work on a OnePlus 3 but try this sequence from the phone dial pad: *#*#4636#*#*
this will either do nothing, or enable a hidden (testing) menu (I am not sure if this is baked into Android or device-specific, but you will see). If you get the "testing" menu, go into "Phone Info" and scroll down to "Turn On VoLTE Provisioning Flag" and tap once (if it says "Turn OFF..." try toggling off then back on).
I am considering the OnePlus 3 (on T-Mobile in US) and would like to hear your feedback. On a side note, do you know if Wifi-Calling works for you? Try enabling "Airplane Mode" and then turning on Wifi and making a call... Also, I have heard you should have "WiFi-Calling" in your Settings if it is supported? Thanks in advance for your response!

If it defaults to read "Turn Off" then it is turned on (enabled in software)... That's too bad about Wifi-Calling... That's a feature every new device should be able to support...

Yes, I have been using it on JIO from Day 1. Ofcourse, you have to set the other Sim to 2G or 3G mode and use JIO sim for Data in Settings. Works alright after that.

You have to change your APN to T-Mobile IPV6 and it will go away. I'm on T-Mobile and I am getting volte.

US998 Hidden Menu LG V30/V30+

EDIT: If the dialer code doesn't work for you, see this post for another way to access the Hidden Menu.
________________
US998 Hidden Menu LG V30/V30+
So, I went looking for the hidden menu dialer code for the US998 LG V30.
https://www.reddit.com/r/tmobile/comments/75tbsc/lg_v30_and_others_engineering_menu/
*#546368#*998#
That's a different menu, and doesn't provide the band locking option and you can break your CA and LTE combos if click the wrong thing. Just wondering if that code works. You can get to the Engineering Mode, though.
Click to expand...
Click to collapse
Found it. Literally you copy and paste this code into your dialer. Do not hit "call". Once you paste it in, the menu instantly pops up.
Unlike for the T-mobile variant, it doesn't let you checkmark off all the bands you want -- at least with AT&T Prepaid, which I have. I think the bands it shows it dependent upon the SIM card you have in your phone.
I was able to click each LTE band my phone IS showing and with one exception (LTE band 30), a box popped up and "Success". Whatever that means.
I think if I had AT&T postpaid it might show more bands. (AT&T Prepaid doesn't allow domestic roaming, but does have roaming in some other countries.) Or if I had T-mobile it might show different bands, like even LTE band 66. Since I have AT&T Prepaid -- with no U.S. roaming -- it's not going to show me a band I'll never use? At least that's my working theory. While the dialer code is the same, possibly options are different depending carrier/SIM card[/B]
You can also go into the Service Menu and turn off MOISTURE DETECTION. Just an FYI for those who need to know that.
I did go into the some of the VoLTE/Wi-Fi calling settings. While VoLTE was already enabled, VoWifi (Wi-Fi calling was not). I enabled it. As an AT&T Prepaid customer, we don't get that yet, and I don't really need it. (I have Google Voice.) But I checkmarked it to enable all that. Didn't seem to break my phone.
I took some screenshots to get into the LTE bands menu, but I didn't take screenshots of the other stuff. Of course, be careful! You can break functionality.

LTE BANDS on AT&T Prepaid

Okay anybody know how to get the LTE band selector back to automatic? Apparently clicking on one of the bands chooses only that band. I am stuck on band 12 which is prevalent in the Atlanta area, but I would like all bands.
By clicking on band 30, I had no LTE whatsoever . I had to click on band 12 to get some LTE signal.
In that menu, I do not see a method to choose a batch of bands. I only see a method to choose one band at a time. Whereas before I mess with the menu I had several bands automatically depending upon signal strength.
I rebooted my phone, hoping the band selector was only for that one session . But still I'm only seeing LTE band 12. I don't want to reset my phone. This got to be away to make it go back to automatic.

Whatever I just did, now I can get other LTE bands. I'm now on LTE band 2.
But I didn't choose LTE band 2, it just found the strongest signal. Whew.

Funny, i did the same thing this morning when playing with the menus. I thought it was a checkbox and saw a 'SUCCESS' toast show up on clicking. Oh no , what have I done.
I rebooted the phone and everything seems to be back to normal.

A slightly different code for the AT&T version of V30
The code didn't work on my AT&T version, BUT!!!!!! ........ I noticed how the last 3 digits correspond to the unlocked version and substituted them with 931 which corresponds to H931/AT&T phone version and voila!! I get into the hidden menu.
So for AT&T version of V30 the code is *#546368#*931#
Enjoy!
The menu looks a bit different though e.g. band selection is not there

I'm still concerned I may have done something to prevent my LTE bands from automatically switching properly. I've been on LTE Band 2 for two days now and only LTE band 2. Normally traveling to and from work (30 miles down I-75 and across I-285 perimeter) I'll switch bands, according to LTE Discovery app.
But today I'm heading into north Georgia where LTE band 4 is prevalent, so we'll see...

reposting here also as it's very relevant to the US998 hidden menu.

Hey All,
I unfortunately messed around with the LTE Band Settings on my US 998 (US Cellular) in the hidden menu and am now worried that the phone is locking to specific bands. Right now, no matter how many times I reset network settings and restart the phone, it will only lock to one band (12 or 4). The lock is dependent on which LTE Band Setting I select. Anyone know where in the hidden menu I can reset the band selection? Any help would be appreciated.
Thanks!

Please tell me exactly what you did to fix the problem? When you factory re-set, did you allow Google to restore your data and apps? I really don't want to do a factory reset if I don't have to.
I've already tried airplane mode, as well as chosen other bands (I stick on them unless I re-select LTE band 2.) As well as rebooted multiple times daily.
I've been stuck on LTE band 2 for 4 days now. I selected LTE bands in that hidden menu and it stays only on the one chosen. Before that I was stuck on LTE band 12, but 2 is better than 12 if I have to be stuck on one.

Unfortunately that doesn't help. It's the US998 menu. You click it, it chooses that band. You click another it chooses THAT band and only that band. It stays in the last band you chose and only that band.
I can select another band besides band 2, but I would then be just choosing another band to be stuck on. I did that initially when I was stuck on band 12. Now I'm stuck on band 2, which is better than being stuck on LTE band 12 in the Atlanta metro area.
I went up to North Georgia last weekend where AT&T LTE band 4 is prevalent, and I was on WEAK LTE band 2 the most of the time, and then on HSPA. I never switched to LTE band 4.
That's why I asked the guy exactly what he did to fix it. He said factory reset, but I would like his details. I don't want to completely reset my phone for nothing. If only a true factory reset will fix it, I'll wait until next weekend when I don't need my phone during the daytime.
Also, did he allow Google to restore data and apps?

Has anyone found a solution to this? I have tried a factory reset and it did not solve the issue. I also tried a couple things such as changing the RAT Selection to WCDMA ONLY (since VZW) and then LTE ONLY and then to LTE/WCDMA but that results in no service at all whereas I at least have service with WCDMA ONLY or LTE ONLY.
I imagine there should be a simple way to fix this as it is literally just disabling bands in the modem...it is just a matter of figuring out how.

same issue here. anyone succeeded in restoring the default settings? weird hidden menu on this Phone and keeps me frustrated...

Hey Chazz, sorry for the delay. I have notifications turned off. But yes, I had to do a factory reset from scratch. I didn't restore any settings and started with a clean slate. I then used LTE discovery to see myself connecting to different bands. Toggling airplane mode showed band 4 and 12.

Thanks for the answer. The V30 with the problem is now my backup phone, as I'm using a V30+ as daily phone. I didn't dare touch this menu on that one or my wife's V30.

Yeah, the US998 needs the T-Mobile hidden menu, where you can select all the bands you wish, not just one at a time. Very strange design choice from LG.
There is an option in the hidden menu to reset networks. Did you see that? Maybe that's what needs to be chosen?

I also see Network Settings Reset in the the regular Settings menu. I don't have a SIM card in this phone, but if I did would it re-set ALL my network settings?

I think the Network Settings Reset in the regular settings menu is already covered by the factory data reset. Thanks for getting back to us though. I'm not entirely sure if Factory Data Reset worked for me or not. T-Mobile around where I live is mostly Band 4. I've looked through cellmapper for towers that had band 2 and were spotted recently, and as I drove by them I didn't notice my phone connecting to anything other than band 4.

OnePlus 7T Global ROM - Voice over Wifi (vowifi)

I've been looking all over the Internet about enabling Voice over WiFi on the 7T with the Global ROM. I've found several sites talking about the 7T Pro or 7 Pro, and I've tried those techniques and was able to get the voice over WiFi setting to show up, but when I toggle it on, it is turned off again the next time I enter the Sim menu. I've verified with Verizon that Voice over WiFi is turned on for my phone, my phone is registered in their DMD, so everything should be good on their end. It just seems to be an issue with my ROM not allowing me to use it. I apologize if this has been answered but I couldn't find one for the 7T that matched my situation.
Alternately, this was originally a T-Mobile phone that I converted to the Global ROM. How would I go about converting this phone to the regular US ROM (from here, for example) to see if that would fix my issue? I don't really *need* the Global ROM, I just installed it because that's what the conversion guides to get off the T-Mobile ROM prescribed.

I wouldn't expect the us rom to work for your issue if the global one does not. I'd also note that I find vowifi with it to be finicky without any display on why it might be failing. I have 2 sims in mine, and its well known now that one can't get vowifi working without the primary data sim being the sim you want to do vowifi. but even when I do that (and even set primary calling sim to the tmobile one), it more often than not, doesn't connect via wifi (i.e. pop up the icon). It has worked (i.e. I have been able to get the icon and place calls while in airplane mode to the US while overseas), but it hasn't proven to be reliable. Then again, it wasn't reliable either with just a t-mobile sim and the t-mobile rom. I just wish there were some logs that would say what was failing.

What process did you follow to get yours working?

I don't have verizon, as I noted. as I said, I would play around, set primary data and calling sims to the # I wanted for vowifi. Put it in airplane mode, turn on wifi. sometimes that would force the vowifi to come on / sometimes not. take it out of airplane mode. sometimes that did it hen the previous step did not, sometimes not. rinse and repeat.
I mostly gave up on it for now. The only US number I give out is my google voice # anyways, so it doesn't make a huge difference.

I only have one sim, so I don't think the issue is with it not knowing which is the primary. I tried the airplane mode trick but it just said I had no connection to dial. The issue with me is until I did the little hack shown here: (https://forum.xda-developers.com/t/guide-enable-volte-vowifi-on-all-devices-no-root.4105817/), I never even had the VoWiFi option, but even when I got it, it wouldn't stay enabled. I was thinking the US ROM would help because I am in the US and my carriers are all in the US. I felt like the Global ROM maybe wasn't compatible with Verizon or something.
Bonus question: Is there an easy way to search within a single thread on this forum? I can only find how to search all the forums and it makes it difficult to zero in on information.

Verizon DOES NOT support VoWiFi on the 7T. So far as I know they do not allow vowifi over their network on any non-verizon branded phone.
VoWiFi turns on, fails to get the proper authorization from Verizon to use their network, turns back off.
Even with the 1+ 8, the VZW model is the only one with vowifi on their network. I was told that it was due to “security concerns” since non-vzw phones didn't go through VZW testing.

Thank you for the Search help, of course it requires clicking the button I'm so used to typing and hitting enter I don't even click those anymore.
On the Verizon VoWiFi, I wonder if results may vary on that, because they had told me it was enabled for my IMEI. Of course, that is largely dependent on the rep you get, I'm sure. But at minimum, I'd at least like to have the option to try it. Plus when I travel abroad, I would like to be able to turn it on for other carriers there as well. I did find another route that involves using PDC to manually enable it, but I'm going to have to root the phone for that. I'm not using the phone yet, so now is the time to play with it I appreciate your answer though, it may be for nothing, but I've got the mind of an engineer, you can't tell us no

I was unable to get either VOWIFI or SMS to work when I bought my unlocked 1907 7t (with global rom from factory) to work on Verizon. (Despite all the guides to do as such)
I both messaged them on their platform and called several times. Every time was same shtick. Them: "Phone doesn't support all features" Me: "Yes it does, has all bands, please add IMEI to database and turn on cdma-less provisioning" Them "Ok, hold please..." 5 min later... "Ok it should enable within 24 hours...when should we call you?" Me: "Same time tomorrow is fine" Them: "Ok, then"...24 hours later... no call, I call, repeat, no change.
They honestly just lie/yes man you to appease you until you give up/satisfied with their programmed responses. They have no intention of going out of their way in any technical capacity (Esp. if you're prepaid) and being forthcoming with their policy to only activate "Verizon Phones" on their network will never deliver a technical reason (this band/that band, etc...) This was not the first time I've had to attempt technical workarounds (on another global unlocked LG phone) , which also failed (on their end). They are an incredibly dishonest company imho.
So I got a T-mobile sim and it works great! (vowifi perfect!) I keep the old Verizon one in the second sim slot, just in case I want to punish myself at some point in the future ;0

See, my SMS works fine. That's why I say it seems to depend on the rep you get. I'm just really curious if I could get around the carrier block OnePlus has apparently put in place for VoWiFi (per their customer service), if I could get it working still.

There is some sort of certification or something baked into VZW phones that their network looks for when you try to connect via VoWiFi. If that is missing VZW's network will not let you connect even if customer service ”activated” it.
It's not a carrier block 1+ put in place, it's a “not VZW certified” block that Verizon put in place.

Oh, I see. Idk what OnePlus was talking about then, because they literally said they block VoWiFi if it's not T-Mobile.

Hi, this solution perfectly works for me. Link. So simple way to enable volte and vowifi without unlocking bootloader and rooting.

I use telefonica uk commercial since oos10 for malaysia and my telco is digi and unifi. but for 11 i use required to use from extracted mbns, so i tried using extracted pixel4 mbns. Still lookimg for op7T oos 11 extracted mbns.

Question Volte

Has anyone had this working yet, does it even have an icon to show its on because my network provided said the Pixel 6 has no option in the menu, does it even show on the phone if its working/on?

VoLTE is working fine with EE in the UK. There are no signs it is working from what I can see, except for the fact it stays on 4G rather than drop to 3G. I've had HD calls (shows the tiny HD icon when the call connects) on 4G as well.

You can check using the phone service menu (*#*#4636#*#* or a version of the same... I always have to check!).
Mine shows volte provision as on (EE UK)

Mine is greyed out

It depends on your carrier.
Some offer the ability to activate it on your own (call a number, send an SMS), some activate it automatically, some won't even give you the ability to deactivate it/activate it yourself.
It needs to be activated and attached into the carriers system as an information that it's activated for your contract.
Are you sure that VoLTE is activated properly?
I have no problems with activating it on my phone.

I've been in touch with them today and Volte is active on their side but I've got no option

Same problem here ... Youfone network in Belgium ...
VoLTE works fine when I put the SIM card in my OnePlus 8 phone.
VoLTE does not work on the P6P if I insert the SIM card there.
I chatted to a Google support guy, he said it definitely is the provider whi must change something ... they claim the P6P supports VoLTE properly ...
But that is strange to me ... why would the SIM card have VoLTE in OnePlus phone and not in P6P? Could the provider really fix that? I doubt it ... but I am not a VoLTE specialist. I will contact provider anyway to see what they have to say.

Hmm ... I checked my provider's website ... they (explicitly) say that VoLTE is availabe for the following phone brands: Apple, Huwai, LG, OnePlus, Samsung, Sony, Nokia, Oppo. So maybe indeed the provider has to "activate" it for specific models/phones ...

I'm told after checking settings that Volte is switched on in fact it can't be turned off due to the carrier config file, greyed out on 'yes' however no Volte working.
The phone supports all the bands so this has to be an issue with the phone itself

No option for Volte and carrier confirms this, Google has hidden it for some reason

Hmm ... see attach. Same issue here. VoLTE works on my OnePlus, does not work on P6P. Chatted with Google support (see attach); they claim it is the provider who has to activate it for the P6P model (which I find strange). I will check with my provider (but I'm pretty sure they will bounce me back to Google). Ping pong.

So I hate volte because if my phone signal is weak and it decides to call over data the call gets all distorted and robot like if you know what I mean!! So I always turn this feature off, normally! Been a Samsung user for years and always had a setting to turn volte off via the SIM/network menu, well as it seems I've had a few of the distorted calls and gone to turn of volte but not a setting in sight and I think I may have figured it out. Seeing this post triggered me look into it deeper and after using that phone code above to establish that the carrier volte setting is switched on but greyed out, as somebody posted above made me switch my SIM to My S20 and check the volte and I can confirm that although the mobile provider has it switched on permanently for active Sims the phone has the hardware to switch it off.
If you look at the screenshot from my Pixel 6 Pro and read what toggling the WiFi Calling switch does, it actually states "When Wi-Fi calling is on, your phone can route calls via Wi-Fi networks OR YOUR MOBILE'S NETWORK"
What I take from that is the toggle on/off is for both WiFi Calling and volte at the same time and we can't have them as independent switches like on my S20 and probably other phones. It makes sense as to why none of us can turn it off, which is cr*p. Especially when my mobile signal is dodgy in my house so I relay on WiFi Calling and sometimes as I have 2 AP's I could have low WiFi signal so it decides to use volte but my mobile signal is also weak thus making my robot distorted calls to happen. I'll be sending feedback via about/send feedback to Google and just hope somebody picks up on it.
Do you agree?
Unless I'm missing something then appolgies for waisting your time.
If you do agree please could you send feed back to Google via "settings/about phone/send feedback about his device" as the more reports they get we have a better chance of the toggles being separated.

I don't even have a setting 'Wifi calling' ... so I guess this is present in your case exactly because VoLTE is enabled.

Have you opened settings and searched for wi-fi calling?? See screen shot. I'm guessing you have and if it's not there then possibly your network provider doesn't support either... Is your phone on the latest firmware?

I do not have a setting when I search for "Wifi call". My phone is on the latest (November) firmware.

That's strange and does your mobile network support both WiFi Calling and VoLTE services? If so then all I could possibly suggest is maybe a factory reset, making sure all your data is backed up first of course. It's a bit drastic I know but sometimes it does fix issues especially if the update missed some steps out when it was applied.

Well, VoLTE for sure, when I put the SIM card in my OnePlus phone I have VoLTE (not wifi calling; that may be the reason why I don't see the entry in settings).

Quite possibly, like you can't have one without the other... If I'm correct that they have a joint on/off switch I really hope Google fix it. Hope you manage to get something sorted.

This is a carrier setting first and foremost. My phone came with it enabled on EE here in the UK, but not explicitly. I have Wifi Calling enabled on my phone as well, and I believe that works for wideband voice calls.
I've tried both VoLTE (unmarked in status bar, just as "HD" in call log) and VoWifi, both seem to work with my P6P.

Update: I've had one call where its shown as HD (Volte) on my call log even though the areas I go are all covered by Volte so I'm going to guess this is down to the rather poor modem on this handset which shows weak signal strength compared to my last handout (Oneplus 8 Pro)
