question regarding nougat - Android Q&A, Help & Troubleshooting

Hey everyone,
i am new here, i have a question regrading android nougat.
i am a Moto Z Play user. problem i am facing is i cant enable VOLTE on my sim if i eject it once from phone.
to elaborate once i insert a sim on my phone it registers it and VOLTE and 4G internet works fine.
but if i eject it once from phone and insert it back only 4G internet work i cant make calls.
only solution to this problem is i have to change sim card.
after doing some tinkering i understood problem it seems once saved the volte setting are geting disabled
i need to know where does all this sim registration info is stored in nougat.
probably removing all this info and restarting my phone might help me from going to store to get a new sim.
have cleared cache from setting and tried alot of steps.
suggestions are welcomed.
any admin or moderator may move this post to any proper sub category as am not aware where to post.
thanks in advance

[Q] "Unable to connect. Try later"

Hi there!
I've found several threads with this issue, but still not that serious like mine.
I've been using my GS II for 3 month without any problem, untill yesterday. During surfing on the net the network suddenly gone away and since I don't have mobile network connection. I've got IMEI, CSC, signal from provider (unlocked phone), my SIM card works in other devices, I also updated the firmware, I made several hard resets, checked other SIM cards, checked the problem with flight mode, but I haven't found any solutions. The signal sign is there in the upper corner, but I'm not able to connect to any providers for 48 hours.
Please help me. I don't know what to do
Maybe a country specific CSC change? I don't know how to do that. I have one .tar file for that but Odin can't install it. I'm a beginner here...
Thanks in advance...
Have you tried checking the access point settings?
Sent from my GT-I9100
Yes. They are fine. I've just changed them and put them to default again because there was no change.
When the phone went offline I was just surfing on the net so I did not change any options.
Any other ideas maybe?
Thanks...
try talking to your provider. Your account may have a problem which could be fixed by a simple reset on their end.
Thanks for the comment. Well, I've tried to use other sims for the same and also from other providers, even a sim from another country, and none of them worked. I also tried to put my sim into another phone and the sim works fine there. The only logical solution is that the problem is with the phone.
I guess it's worth a try, maybe they blocked the IMEI of the phone because of something? It's not a stolen mobile though.
Now I've got a flashed brand new mp4 player from samsung. Nice, it drives me crayz...
Another idea. While I was surfing on the net I installed "advanced task killer" (before the "crash" happened) and I killed some ordinary apps (not sure about this) then I just deleted the program. This connection rejecting thing happened after this. That's why I thought I should make a firmware update, maybe the problem was caused by this task killer. Well, don't know if the is a connection or not...
I have exactly the same proble with my Galaxy SII - I went on a long trip - when I got back it stopped working. Has anyone found a solution to this?
To reiterate - the phone sees all the networks, but when I select Vodafone UK I get the message "unable to select vodafone UK automatically". The sim card works fine in other phones - there is clearly an issue with the phone. The only thing that has changed is I have updated some of my apps on returning home.
Any ideas?

My CSC is XEU (correct for UK as far as I can see - and has worked for the past 3 months)
Sim card works fine in another phone
Network is fine (my wife is also on Vodafone and has no issues - my sim works on the network on her phone)
My Imei is correct
-Everyone else who has had this problem had no joy with a factory reset so I'm loathe to try it until I''ve tried everything else.
Any other ideas?
Just to recap:
The phone is stuck in emergency calls only mode
I can see all my local networks (Vodaphone, Orange etc...)
When I try to connect (in any of the modes 2g/3g) I get the error message
The sim card works fine in other phones
Other people's sim cards have the same issue in my phone
There are plenty of 'Emergency calls only' threads around, but the ones that have my exact symptoms never seem to get solved. Does anyone have any other ideas, or better, has anyone come across a thread where the issue was resolved? Getting pretty desperate.
tried rooting and flashing different modems maybe its a hardware problem with the modem.

i have the same problem in greece galaxy s2 i9100....in ics i havent network in 2.3.5 i have...i dont know why...in cm9 ics i have network...
Last update - I have flashed the phone to Ice Cream Sandwich, (LPQ version), which means I have:
Carried out a factory reset
Flashed a new ROM and Modem
When I rebooted it asked me for my carrier (Vodafone UK) and filled in the APN settings itself. I still have the same issue. I can't work out what is left that I haven't reset/reloaded that could still be causing issue. There can't be many settings left that aren't new?

i try to put manual apns but i cant save this in phone...in network search found my carrier but not conected...only with cm9 ics found network...pff...
Success?!?! It looks like we have tracked down the problem (extremely helpful input from another forum). Quick call to Vodafone and it turns out that my IMEI has been blacklisted (stolen!) Imagine my surprise - currently having a very interesting with Carphonewarehouse as to how hey managed to give me a stolen phone - should hopefully have everything resolved shortly

Very odd - when you first boot after a flash does it not ask you to select your contract type (that is the bit that automatically fills in the APN for me?)

this helped to me
Had the EXACT same issue on my Galaxy Note II for two days. My last hope was trying to restore my EFS with the EFS pro app.
Now when enabled my wifi at home and connected to my home network my sim prompted for the pin code.
Strange but I guess it was waiting for a connection (from my home wifi (not any other wifi) from a "half downloaded" app from the play store.
Anyways I'm happy this issue is resolved.
Does your phone prompt for a pincode when you start it? (mine said unable to complete download everytime it booted)
Hope this will help you guys...
Samsung Galaxy "Unable to connect. Try later" issue still remain
Hi guys,
I have the same issue with the following device:
Samsung Galaxy S3
I live in continental western Europe. Operators tried: BASE, MOBISTAR, PROXIMUS, POST.
The IMEI is correct, does not start with 00. The phone was bought from a shop, new, I have the invoice, so is legal, not stolen.
For some unknown reason, suddenly it does not want to connect to the mobile operators, any of them. I see "Emergency calls only". When I try to connect any one automatically or manually, I always get the message "Unable to connect. Try later".
The SIM card work well in another device, a Nokia C3-00. Another SIM does not work in my defective Samung S3. I sent back the device to the shop to be repaired and they gave it back to me saying it work very well, they just upgraded to the latest firmware, etc.
I am very annoyed because the device is unreliable. I have it in my pocket and do not realize it is not connected to the mobile network, I cannot be called or receive messages. Also I am unable to call.
The WIFI work well.
I tried everything, removing the SIM, inserting another, shutting down, enabling and disabling flight mode, nothing works.
But the later for some unkown reason and logic, it just work again for some time.
You guys wrote about some solution by looking in a folder, but I don't see that folder. Also you mention rooting. Does this mean cracking the phone? I do not wish to meddle with this, because I could destroy my device and I paid a lot for it. It will remove the warranty. So if you have a solution, please give a legal one.
Anyone have a hint or explanation for this strange behaviour?
Thanks a lot.
had a similar problem with galaxy core prime.
bought without a sim card and no knowledge of what network it was on.
every sim i tried was getting unable to connect error as i was trying to register on network
dont know if this will work for everyone as mine is a dual sim phone but here goes.
inserted two different sims from different providers, ee and vodafone.
reset phone to factory settings and when it booted back up, it recognised the ee sim card, went to mobile networks and network operators in settings and selected the ee network and presto, it registered ! used sim manager to select voda card and repeated selecting vodafone as carrier and it also registered straightaway
as i said none of the cards would register before on their own, but somehow this method worked for me.
hope this helps
had to set one sim to gsm only and other to autoconnect

[Q] Vibrant Not Sending/Receiving Calls/Text Not Even Internet! Help ?!?!

I cannot receive calls or texts nor send them and i cannot get on the internet or use anything that needs data. my Vibrant says full bars on Edge - Sometimes it shows a G. But the problem persists. I have tried Factory reset, i have tried another sim card and it still doesn't work. i have had the sim card and SD card slots replaced. and its still doing the same thing. Pleaseee someone help i will Gladly appreciate all the help i can get from anyone out there trying to shed some holiday grace on me!!!! please help me. Thanks in advance!!!!!!!! BTW Happy New Years to ALL, since it's right around the corner!!!! Help
You probably need to restore your APNs.
Settings>wireless>mobile networks>apn. Don't forget once you put them in, hit menu and Save.
thanks for the reply but I do have my apn set right but for some reason it still doesn't let me use my sim card. What can it possibly be?
Not trying to be a smartass here but make sure your sim card is in correctly. Had this happen to someone not too long ago and went through all the troubleshooting things only to find that he put the sim in wrong. Once he figured it out, fixed it and it was like Vegas baby. Everything turned on.
Sometimes it might just be something simple like that.
Maybe check your modem too. Might need to flash a new one.
I have the sim card in right because it does show Tmobile in the notification but how can i change the modem if you can give me a step by step guide. Please i would appreciate it =D
Assuming you're rooted you can just flash a different modem. You can find all the vibrant modems here:
http://forum.xda-developers.com/showthread.php?t=868774
I flashed the KA7 modem to see if it would help but the problem still persists? It says "Connection Not Allowed" when i try to connect to tmobiles service. Or "Service can't connect" or "Service T-Mobile Unavailable" but it still says Tmobile on my notification and i can still see signal bars but cant do nothing at all.....Any ideas? I wud love to hear em'
Perhaps your NV_DATA.BIN got corrupted? Did you check your IMEI?
I can still pull up my imei but how will i know if its corrupted?
If it shows all 0s or says Unknown.
Are you sure your SIM card isn't locked? Not sure what ROM you're running at the moment so can't be sure where it is, but Settings -> Locations & Security -> Set up SIM card lock.
I wish i knew what the answer what thanks for all the reply but none were the resolution to my problem i guess its a hardware problem like the motherboard or something =/
Try getting a different SIM and trying it? Could just be something like that.
Thanks for the reply but it still does the same thing with another sim card.
yes i have the same problem but in my case by mistake i delete phone.apk by accident, please help help

Please insert SIM error on all sim except Airtel...lol

Hi guys,
I know my post does not belong to this section, but i posted this query in General section but i didnt recieved a single reply. So i am posting in this section since most developers keep vising this section. I urge mods pl not to delete my post so that i will get help from many people and i will not have to sell my lovely LG Optimus One
From 21st April morning i am getting strange error. I was on gtr_rc_4.6 (Talho ROM). It showed "No SIM card". I thought my inserted Aircel sim card gone bad therefore i changed it to Uninor but even that showed the same error. But when i searched for the network it showed my all the network available but i cannot select any of them.
I have 5 sim cards all are in working condition. But when i insert any sim card other than my default Airtel 9766****** No one works. Only my Airtel 9766****** works perfectly. I had earlier install Where is my droid and Anti-Theft Control app where i registered my 9766 as my default sim.
When SIM stopped working my flashed LG India's 2.3.3 kdz image but problem persists. I had also chaged the Clockworkmod recovery to AmonRa recovery. My mobile is no more in warranty so that i dont want to spend money on the problem which could probably be solved easily.
Regards,
Pl some one help
*edit*
I have contacted the developer of "Anti Theft Control" developers Oneo Solutions regarding my problem they replied, "Anti-Theft Control is not interfering with the phone's ability to recognize a SIM CARD.". I also had installed App "Where is my Droid" earlier and sent mail to them also. They replied "This app will not lock anything to do with the SIM. All will is programed to do is notify you of a SIM change, not lock the device."
As you guys are an android developer, can you please tell me how is this happening? I have installed various custom ROMs but still only my
registered sim works. Is there any software or test using which i will know what is the exact problem?
Pl reply guys
My first thought was a provider locked phone.
But I guess it is not...
Can't give a solution, but if something comes into mind I will let you know.

No network, registration fails

My smartphone won't log in to my network. It recognizes my SIM - I have to enter my PIN - but doesn't log in. I can manually search for and select the network, but the registration still fails.
The SIM works in my other phone. I've already tried resetting the phone and flashing the firmware.
I'm using a Sony Z3 (didn't post in its sub forum because I think it's a general Android issue).
Can anyone help me out here? Thanks.
Edit: It doesn't log in at all aka no bars. Also, I've noticed it will only find my network when I turn on LTE, Not GSM or 3G. Not sure if that's relevant though, might just be bad coverage.
Hey guys, I really need help here. No one has anys ideas?
I've pretty much narrowed it down to the phone not recognising the GSM/WCDMA bands since the factory reset in the MM beta. Is that even possible (if so, any way to verify?)? If that's the case, any way to re-enable the bands? Thanks.

LG V30+ Plus AS998 Sim Card Issue - cant make calls

Hello guys, my name is Ruben im from Peru
First of all, excuse my english, i will do my best to explain my problem
I bought this lg v30+ on ebay (LG-AS998) its unlocked and works great but i cant make calls.
I put my sim card in and i have full signal, 4G, and can enter internet, apps, play, watch youtube and everything works great but when i want to make a call i enter the dial, put a random number press call and the phone show this message "No Sim Card, or sim card error" . I also cant recieve calls. I have others phones and i test my sim card and it works perfect in others phones so im sure its a problem in this phone.
By the way, the phone has the AS99820b version. I also enter the hidden menu
*#546368#*998# - Service Menu - Test and The USIM card test is PASS
Does anyone has this same problem or knows how to repair it ?
Im thinking on buy the sim card reader on ebay and change it (not the trail, the whole reader) but i think maybe is not a hardware issue because i have full signal
I really appreciate it any info, thank you for your help!!

Try flashing to US998 Oreo firmware. See Frankenstein thread on how to do that. One, on the remote possibility your phone is SIM card locked to previous carrier that will carrier unlock it.you will be able to have access to newer updates. Two, you will be able to have access to newer updates.
Also, check your APN in the mobile section of Settings. Should be the APN of your carrier and should be set as the default (green).
Hi Chazzmatt, thank you for your quick reply.
The apn is perfect, im using my carrier apn and i have full signal 4G, i can use chrome, youtube, whatsapp, everything just cant make calls, thats why i think the phone is not sim carrier locked, i wont be able to use data neither, am i right? And i can receive SMS also!! Its weird right?
I will do the Oreo flash when i back home :good:

You're welcome!
Yeah, you have to DL PARTITION when first moving to new variant firmware, like AS998 to US998. "Upgrade" can only be used when already in the firmware.
In the Frankenstein instructions, you normally DL PARTITION to US998 Nougat first, THEN then "upgrade" to US998 Oreo. But there's exceptions. H931 has to DL PARTITION at both US998 stages, Nougat and Oreo.
