Lost signal . Can't connect to network - Samsung Galaxy Note 8 Questions and Answers

Hi,
On the way back from work, my phone lost signal. Reset didn't help, I try to install new firmware but didn't help. Only emergency calls I can make,
SIM card works normal on different phone. In side settings, I see my carrier name.
Maybe someone had the same issue ?

Hello there!
I too have same issue from few months. Did you find a solution for this? Everything else works. Looks like some issue with antenna

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

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

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] loosing Network Signal and it don't come back!

Hi Folks,
how in the topic, im loosing my signal at point where my signal is weak. if i lost it, i can run around to get it back to write messages or call someone. it doesnt work, because my phone say's "only Emergency calls". i wait one hour but the phone can't connect to my provider. The radio is at the moment 32.36.00.28U_4.06.00.12_7, i've already tried newer and older version of the radio img but always the same issue. From the beginning when i had the phone, it sometimes doesn't regognize my sim card, i have tried everything to get it to work (new rom or radio img) but always it fails. on the next day without any changes the phone works again with the same sim card. So now here is my question....... what the HELL can i do to bring it back to work, so it dont lose the signal in weak areas, and if the phone loses it, what shall i do to automaticly reconnect the phone automaticly to the provider. and airplane mode is no soloution for me. thanks for answer.
Have you tried another SIM card in there to see if the problem still occurs?
Sometimes the card itself needs replacing. Just a thought..!
this i havn't tried out yet, but i tried my actual sim card at the phone of my wife and it works a whole day without connection lose. I'm just thinking its a software problem maybe its the wrong radio version.
No "wrong radio version" will lose connection and fail to reconnect.
It's either your ROM or (most probably) HW problem.
You can try to wipe and install a clean ROM and see if the problem persists. If it does - use the warranty.
which rom would u suggest ? I tried CM6 / CM7 / MIUI nearly all modded roms here. The problem is to try out if the rom works i have to go out to a point where the signal ist weak, and hope for a signal lost. Sometimes it works and i get a reconnect to network and sometimes it doesn't work. in zones where the signal is strong i haven't any trouble. Did i get any problems by HTC if my phone is unlocked? I already had it gave to a repair 3 month ago with a broken usb connector and there was no trouble with warranty at unlocked phone but what is now? can they change their opinion ?
I got it. The Problem was the the Phone has to set the Network search to manual and not to automatic search. it works now for over 1 day and it seem that is now no problem with lost signal. Thanks for Help. But i just wondering why i have to chose manual network search an not automatic.

[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?

Question Mi 11 ultra isn't getting phone signal

Hey everyone. I bought a Mi 11 Ultra from china but I don't know why isn't getting signal at all. It detects the SIM but it doesn't let me make or receive calls neither messages, and obviously it doesn't connect to mobile networks. Can somebody help please?
Where are you, what network are you trying to use and have you got some screenshots of your network and SIM settings?
Hey, thanks for answering! Im in Mexico and about the network, any of them. I thought of changing the ROM from the CN to the global one to see if that help, but I need the mobile data to unlock the bootloader, and since the phone isn't getting signal, I cant do that.
P. S. Sorry, what do you mean by SIM settings?
Attached are screenshot of my SIM settings. Yours will be similar. Make sure your apn is set correctly. Make sure your SIM is recognised. Just basic setting checks. May be try other sim slot and of course, make sure it's right way up for either slot.
Without any screenshot I cannot see what may be wrong, so start again with SIM. Shiny side outwards and make sure it is recognised.
Hi again. Yeah, I have tried with both slots for the Sim, each one the correct way, but is the same result for both of them. Thanks for the example of the SIM settings, now I attach mine. As you may see, the SIM is getting recognized, just don't know why isn't getting signal. I've also tried with other company's SIMs, but I get no different result.
Looks good. I think you need to try with another SIM on different network and same. Try this SIM in different phone as it looks all good on screenshot but may be provider has not enabled it properly. If different network SIM known to be working doesn't work in your it must be hardware, hopefully not .
Also look at settings, all specs. Check SIM status and press 5 times on memory for deep phone info.
Hello and thank you again! Yeah... I've tried different SIM from different companys, all of them known to be working, but none of them has worked on this phone. I'm starting to lose hope... But here are the other settings, just to make sure isn't about software
The screenshot show that your radio is off. This is saying that your phone SIM is not turned on for some reason.
There is not much anyone remotely can do, if you are unable to get it turned on.
Maybe someone else has an idea? If not, and it cannot be resolved by resetting the mobile network ( in settings somewhere) or phone reset, then it may be back to seller as a hardware fault. Sorry I can't help. Let's hope someone else can?
Thanks a lot for your effort. Since you told me that the problem could be the hardware, I asked the seller about this issue and he told me that this problem is covered by the warranty, so I'll send the phone back to them. Again thanks a lot for answering!!
Just for info have you seen this thread about att? https://forum.xda-developers.com/t/not-a-recognized-device-by-att.4462649/#post-87088003
No, I hadn't heard about that, but still, I wouldn't hesitate on changing my provider if another one works, but since I tried changing to another provider SIM and nothing happened, I guess it was a hardware problem. Thanks a lot for the info!
Try doing manual search of network. If it shows nothing then try checking network frequencies of your network provider and comparing them with this phone supported frequencies. Sometimes its due to your network provider doesn't operate the frequency which this phone supports.

Samsung Note 9 960N Converted to 960F call problem

Hi
I have Note 9 960N device converted to 960F/DS Dual through software. It was all working well untill it give me "Moisture Detected" warning.
I took it to Repair shop and they dried it and it started well. No hardware was touched.
After I inserted my sim it gave me 4G+ signal and data was working properly.
Then I noticed that I couldn't place any calls nor can I receive calls while LTE/3G/2G option is selected.
I can get and place calls while on 2G mode also Edge data is working.
I got in contact with repairman and they said it is software issue and NVM needs to be reset. I had him reflash the rom and even IMEI repaired/changed but the problem remains the same.
Can anyone please guide me in correct direction or diagnose that what actually could be the problem with my device?
I am not a pro in mobile flashing etc but I understand the terminalogy as am a software enginner and can perform rooting or rom instalation, so your valuable input will be welcomed to guide me in correct direction.
Thanks
anyone here?
