Mobile data stops working after a while - SM-N920C - Galaxy Note5 Q&A, Help & Troubleshooting

Hi everyone. need your advice and opinion.
I am using Note 5 902C for couple of months now. Uptill now, i was using only 1 SIM and the phone was working absolutely fine. Once i inserted a secondary SIM it has developed some odd behavior.
1. this happened once that i stopped receiving calls. when i was told that people are looking for me, i restarted the phone and suddenly i got tons of missed call alerts. no idea why it happened. The problem didn't occur again as yet.
2. more frequent problem is that from time to time, 4G stops working. It only shows uploading arrow but no download. i have to check it constantly to make sure things are working. Whenever this happens, i do the reset via airplane mode. After coming back to life, it starts working again.
Kindly advise what to do? i am not even sure this is because the second SIM.
Waiting for your advise.

Thats such a coincidence, I was googling this exact same problem today and when I did not find anything about it, I thought it might have been a problem with my network. I am having the exact same problem of the 3G turning off and only showing the upload arrow, except my Note 5 is the single SIM variant not the dual one.

so if you having the same issue with single sim, that mine is prolly not because of dual sim.

Nop, I don't think it has anything to do with it. A software bug maybe?

Cant find Network on Kaiser

Hi, I have noticed that a few have already complained about this issue
I'll tell you what happened to me:
I went on holiday from Israel to Jordan for 2 days.
My Kaiser did not roam as my sim wasn't open for Intl. Roaming so it couldn't find a network.
Also I did not charge it so the Battery went dead.
Following that two days I got home gave my Kaiser a full charge and could not get the network back.
I have done many Soft resets, 2 hard resets & spoken to HTC Help Desk.
The only thing HTC could tell me was to send the Kaiser to the UK for repair as they have not heard of this issue before.
Obviously I do not want to send it as I am sure it's not hardware but something else only.
My Kaiser was perched in the US (made in GB)
Network is Cellcom , which by the way I have tried other Sims in me Kaiser since this happened but with no success.
This issue is very frustrating as I feel helpless regarding this issue & I don’t know what to do
If any one has an idea ………….Thanks

First, try just removing the SIM card, then re-inserting it to see if the phone reconfigures itself. You may have to do a power on without sim card, before you re-insert it.
If that fails, do a hard reset so it goes back to factory default settings, then the inserted SIM card should set up the phone settings properly.

Thank, but like I said before……
I have done 2 hard resets tried every way of rebooting with sim / without sim
Nothing works !

hello saper747:
mine switched to flight mode and swap back,it cant find network any more,too,no matter hard-reset or flashing rom,its still.........
looks like we got the same problem, is yours telling "no sevice"? just a "!" on the service icon,right?

I think this MIGHT be a bug/issue
I had this last week for almost 4 hours. I dont think the network was down but if it was then T-mobile did not state anything anywhere
I had reception all day and then suddenly around 5:30pm, I lost it and did not get it back until late evening

Hi , yes its the same problem
It shows the networks arround but it can't register to them only the !.. icon
This has nothing to do with the network carier as the sim works in all my other phones .
Hi i was wondering if anyone has a solution yet ?

I have THE SAME situation. I believe this is the bug which MUST be solved by HTC! Or at least by someone. I still haven't found the solution. Have anybody done??
Has anyone tried what happens when 3G is disabled (GSM mode)?
I'm having the same problem for the last couple of days in the UK with Orange, but when I switch to GSM (Settings->Personal->Phone->Band->Network Type = GSM) it works fine.

I tried to do that - no result. I have made hard reset - no result. I have dowloaded update WM6.1 from offical site HTC and installed it - no result.
Also, during two days, I calculated at least 20 persons who had this problem around the world. I can not believe that nobody researched this problem yet!
Me 2
I am also suffering from same issue.
My kaiser drop network at around 5PM till 1 hr approx, it hapeend for a week almost then I update radio then it was working ok, but still its not permanent solution.
Now a days my kaiser leaves network anytime and then it will not connect how hard u try, reset, hard boot, flash anything and after sometime suddenly it works.... magic.
I check sim with other phones its working gr8. but with this phone network gives trouble, I dont have 3G here in India, so its running on GSM.
Please somebody find solution, I'll post if I get any solution.
Thanks,
Dilip
Did you try with manual selection of mobile network (start->Settings->Personal->Phone->Band->Network)?
i did the network setting and put it as GSM and it works like a champ
BUT
i lost the 3G capabilities. One of the reason i purchase Kaiser is because the 3G capability.
using other Kaiser will give me a full 3G capabilities so i start wondering whether this is a hardware issue or software

[Q] Tablet shuts down when trying to access SIM card

Hi chaps, I have tried searching across the internet with no luck, here's the deal.
I bought this p1000 galaxy tab some days ago from a guy on a forum. tried it thoroughly before paying, inserted my phone SIM, got a phone call, sms, 3G internet, wifi, all working flawless. I used it for some days wi-fi only waiting for my new tablet SIM to be ready.
Monday, I receive the SIM but it still had to be activated. I just kept it in the tablet waiting for it to be OK. Zero problems, just the usual "no service" message like you would expect from a sim that's yet to activate
This morning I finally get the SIM activated, but as soon as I try sending a text or something, the tablet just shuts down. After that, no way trying to boot it up again: it reaches the Samsung logo, then bye bye. If you remove the SIM from the tray it magically comes back to life.
I already tried the usual stuff, like hard resetting and like, cleaning the SIM or something. I also tried with another carrier sim and I get the same behavior. I'm starting to believe that there is some hardware fault with the SIM reader, but I thought I'd try to get some hints from here before calling Sammy's assistance. Also the weirdest part is that it worked some days ago!
If anyone has any idea/experience to share, I'd love to hear from you mates. thanks in advance!
(oh and btw I know how to hit a thanks button)
I'll update the post with further intel, maybe it will help someone down the road.
The tablet does not like freshly activated SIMs. I know it sounds crazy but that's where we are at. We have tried like 4 different SIM cards from different operators, all work flawlessly; The SIM card of the above NOW works flawlessly as well, it just needed a couple days to settle down. I have no idea if this is a software bug, a hardware fault or some strange network settings from my carrier, but the problem seems to be solved for now. Luckily i didn't send it in for repairs!

[Q] N7000 3G Radio failing

I've had my GT-N7000 for about a year. It has been rooted and running various ROMs since I had it and has always worked wonderfully. I had settled on CM 10.1 about a month ago. Since the last 3-4 days I noticed that my 3G signal showed no bars from time to time. Normally, just a quick 'airplane mode' dip and everything would be fine.
2 days ago was still having the same problem and I had to completely turn off and on again to 'maybe' get a signal. If I got a signal, it would only stay there for a few minutes and then disappear.
I changed the SIM card yesterday just to be sure but I still had the same problem. The same SIM card works perfectly well in my GT-I9000 running CM 10.1 as well.
I cleaned the SIM slot contacts, verified the internal antenna wire and even flashed a few modems and still have short lived and intermittent 3G signal. Any idea about what could be happening? Could it be the 3G radio failing on me?
Thanks for any help.
JF.
Anyone?
Does this happen after you move from one area to another? For instance from work to home or Vice Versa?
same problem
Hi there,
I've got the same problem than you. I got my Note 1 year ago, and since few days, I've a problem with the SIM.
On boot or reboot, the SIM is perfectly recognized and works good. I can call without problem, and can connect to the wifi without problem. The problem is when I use 3g, the SIM is not recognize after 1-2 minutes. I mean, I can access internet, do whatever I want, for just a minute or two. After that, the signal drop instantly. I tried:
plane mode: doesn't come back to normal mode cause the phone says there no SIM card
change modem: don't resolve the problem on all XX*** modem for JellyBean
change ROM: I was on German-leaked 4.1.2 Stock ROM, i tried 4.1.2 Switzerland ROM (where I live), 4.1.2 custom ROM and cynogenmod 10.1 (4.2.2). Always the same problem.
Tonight I'll try another SIM in the phone, in the case that the SIM is the problem.
otherwise, I don't know what else to try...

You're ****ed if it's the same problem! I tried a lot of technique and the one I warn you about is changing the RIL. Useless waste of time and ****ed up everything. At the end I tried an app available on the play store for thé modem, can't remember which one. But hey, you're on the track!
Good luck

Are you sure it is the radio causing the problem and not the antenna? I know on mine, the USB charge port can be a real PITA when it
goes bad, and I had to buy about 3 before I found one that worked properly. With the wrong one, the radio signal would fluctuate all
over the place, so that's why I wonder if it could be a bad antenna/connection/board problem, since it is contained on the same
board as the USB port?

I had an update..
I figured out that when i change the network mode to GSM ONLY it runs very well and never drops network signal or get the NO SIMCARD message..
but when i change the mode to AUTO or 3G/CDMA it drops network and gets NO SIM CARD after a few minutes !!
still don't know the reason & still searching
Let's talk about this problem. Mine is similar. Not getting errors with aim card but when i place or receive calls while in wcdma mode, conversation is normal at first place, then after few seconds i can not hear other side, and other side cannot hear me, sometimes that call ends and that is it. On gsm only, calls work normally, but internet is not working, while in wcdma internet works... pretty nasty issue. I tried flashing different roms, tried several modems to flash, problem is not disappearing, but from modem to modem i can see improvements. Sometimes it does not drop at all... can you help me with this?

[Q] N6 - No incoming & outgoing Calls, mobile data gone.

Having my Nexus 6 for almost a month. Things working perfectly in the starting(or after reset), but after two or three days, No incoming calls, no outgoing calls. No mobile data. Cant realy tell it as a mobile sometimes. Wifi is working good always. After reset, it is working properly for two or three days. Whenever it is not working, I am able to see a !-mark near the tower bar.
My mobile always connected to 4G when no wifi.
No Custom ROMS and no root. Plain Android given by google.
Anyone having this issue. Any suggestion?
Go get a new SIM.

I was begining to think i was the only one who had this problem!
Yesterday morning i woke up and to my suprise my signal bar had a (!) it it but it was still displaying my regual signal level.
I switched my wifi of and i couldnt get a data connection just the (!) sign. I got my girlfreind to give me a ring and see if a
call would go through which it didnt it just said that i was unavalible. I then desided that a reboot might sort the problem
but when i my phone booted back up i was presented with the holow triangle signal icon to say that i had to signal. I then
popped my simacard out thinking it could have just been a bit of dust on it. I gave it a little bit of a dust of and popped it back
into my phone and i was given the same no signal and emergency calls only yet it was picking up that there was a simcard inserted.
The day before i had flashed the alpha version of PA so my next thought was that this would be a ROM bug and went ahead and
flashed chroma which i was using prior to PA and i had had no issues with. Held my fingers crossed as it booted up but much to my
dismay i was greated with the same no signal problem but i went into the settings and searched for networks. Three was one of
the network it had picke dup so i tryed to reconnect to it but i got the toast to tell me i couldnt connectto the network and to
try again later. I checked the APN settings and it had automatically grabbed threes APN from the sim card so at this stage i was
completly baffled by them problem.
My next move was to try my sim in my girlfreinds phone and what do you know it worked a charm. As a last shot to check everything
was okay and i was upto date on my bills etc i gave three a ring and they told me there was nothing wrong with my sim and everything
was working as it should be and that it was a problem with my phone.
That brings me to the point i am at now completly baffled as to the problem and slightly angry at the 2 week old phone that had been working
perfectly up until now has suddnely desided to stop with no warning.
So you are not the only one and i expect their are more of us. I am going to flash the offical stock rom from google and see if that does the
trick but im not holding up much hope i feel like im going to have to contact google and find out where the problem lies.

I got this as new nano SIM from the retailer and seems like working in all other mobiles except Nexus 6. Also I can see lot of people having the same issue with Sprint Provided in US. One more Victim replied too.

i reverted back to complete stock using the image from there site to no luck so i relocked the bootloader and took it back to the carphonewarehouse and they straight swapped it for a new one which is working perfectly
My sim died after a month. My calling went out and then only lte worked no 3g. Got card replaced and it works perfect now. I have US Cellular.
I've posted this in few other threads also, but I had also problem where I only had tgt exclamation mark no matter what I did. I solved the problem by waiting like 5sec before inputting my pin-code. If I input my pin code too fast after a boot, it will open my phone, but won't give me cellural network. This seems to happen in every ROM I've tried
Hi,
Solved the issue. Working fine after enabling request for SIM Pin and set my sim pin.
Usually i disable sim pin lock to have uninterrupted boot. But with ROM this is not working.
Enabling SIM pin request solves the issue.
Is this problem with carrier or Android L?

I have not seen this issue on three devices I've owned with Lollipop. So it appears to be a carrier issue?

HTC One M7 No Network with Working SiM

Hey guys, I've been recently having a problem with my HTC. Basically my phone seems to be not receiving any network even though the phones reading the SIM. I thought it could've been my SIM card so I rang my network provider and they sent me a new SIM. But still the same problem because ive tried the SIM on another phone and it works perfectly fine.
I've tried to factory reset the phone yet it hasn't solved the problem
A very unusual thing happens as well. Sometimes I will get full service or a few bars and if I try to call anyone then nothing seems to happen - it hangs up after 5seconds. I've also tried to use data when the service comes on for a bit and sometimes it comes up with E which is 2.5g i think? So very slow speed. However this works for about 5s then the network goes again.
I have tried to manually search the network and it sometimes finds it and sometimes doesn't.
Really not sure what the problem is and very concerned the phone is over 2 years old but still looks brand new!
Would really appreciate if someone could help me. Thank you in advance!
