Strange issue with Sim card - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Few days back I had issue with the USB module. I went to samsung repair store to fix it (not the authorized one ). After that I was returning home and mid-way the signal went to zero. I tried different roms, full wipe, stock rom but nothing worked.
Now the strange thing. Next day i was going back to work and mid way the sim started working, even 3G was working fine. But again when i was going back home the same issue happened.
So i tested and found that 1km around my house, i get no signal and the same issue occurs on few other places. Same sim works perfectly on other phone.
Has anyone faced this issue?

Sounds like your device is having trouble registering at your local base station. A call to your service provider might help. Good luck!

also check your logs for rill crashes. You could have a rom with faulty issues there.
Or you may not have connected the usb module correctly. You may need to check if all connectors are properly aligned.
However its more likely if its at the same geographical location your connection breaks that its a bad connection area. Call your provider and tell them lol

No carrier and reboots

Need help!
My diamond searches for carrier, but can not find it. Whan i manually select the network, it shows all available, but when it select one, it sais "no signal". When I try to call, it sometimes reboots. On some roms it reboots in a loop, showing htc animation. Without a sim card it works fine. No reboots.
Phone is shure GSM/3G, and it is sim unlocked.
I set up HardSPL, I flashed different radio versions, and roms as writen here. Nothing works. Any suggestions how to make it work?
have the same problem too here man, running t mobile. have tried a whole lot of roms and radios but no luck. I have gotten rid of the restarting problem now but it just cant find a signal to my network, im about to just give up and send it back in
Some more details on the issue.
It works fine, when I plug it into the charge.
Sometimes I can call when it`s plugged into my PC USB.
Doesn`t work without any external power.
A local service center (not HTC) said, the "gsm-radio module" is broken (hardware), and they don’t have any to replace it. They may replace it, if I find the analog.
Does anyone know, which "gsm-radio module" is used in diamond, and are there any other phones (Samsung, nokia ...) with the module, that will fit in diamond?
Does the official htc service repair the phones, if there is no guarantee?
Please help me someone
ya i get a signal too when its in the charger, but still get many dropped calls. it sucks that so few people have this problem and there has yet to be a solution to it. I think im just going to send it back to htc to get it fixed as it does not seem to be a software issue.
I've also recently started having this problem. Mine seems to work fine if it's at 80%+ charge, but as soon as it drops below, it has problems connecting to the carrier.
I've emailed HTC a couple days ago, but haven't heard back from them.
EDIT: Want to add that I'm on 1.93.831.1 WWE ROM and 1.08.25.20 Radio.
I don't have the restarting problem, but I do have a "fake" reception problem where it'll show that I'm connected and have signal, but I won't be able to make or receive calls.
Bumping this thread to see if there's been any progress with this issue.
HTC STILL hasn't replied to my queries. I've since sent another one and haven't gotten a response. Their customer service really is terrible.
same problem here :/

Nexus one not reconnecting to mobile network

My N1 will not reconnect to a mobile network if it has been sitting for a few hours in a no-coverage area, such as a building. I cannot get it to reconnect, even after refreshing the network search. This action only leaves me with no result or a message saying that there was an error in searching or connecting to mobile networks. The only solution is to restart the phone. Every time I try to turn the phone off after this error has occurred, the shutdown sequence hangs until either I become frustrated and do a battery pull, or it automatically restarts and do a battery pull, or it automatically restarts itself. Furthermore, the phone used to give me an error notification saying that the phone does not have carrier service. Now, it does not. Furthermore, the phone used to give me an error notification saying that the phone does not.
I tried uninstalling all my programs and nothing has worked for me. I've also tried toggling the airplane mode to no avail.
I'm considering putting on the cyanogen ROM to see if it would fix this error, but I am hesitant to void my warranty. It's a pretty serious problem as I'm very frequently in a building where I don't get service. It's quite frustrating to have to wait to reconnect to a mobile network once I leave the building and hope that the error didn't occur or have to do a battery pull every time I realize that the phone simply won't reconnect.
Can anyone suggest any solutions?
Mod it. What have you got to lose? Your overall performance will increase. The radio signal may even improve. Your call.

Hey!
You dont want to lose your warranty, then use it!
Your phone seems to be faulty...
My phone is experiencing the same problem as of yesterday. Won't connect. Wonder if it's a T-Mobile issue.

Its only glitchy coz you have stock rom
Cyanogen is really stable and adds alot of features / functionality.
Fair enough you dont want to lose warranty but i remember in the general thread that lots of hardware failures and others can still fix your n1 under warranty even though they unlocked the bootloader.
I too have this problem, hopefully the 2.2 update will fix the problems.
Can you guys confirm if its android or your service provider thats causing this...

I have the same problem and it's starting to bother me a lot because my car is parked in a garage with no coverage. My in-car BT then becomes useless as my phone won't reconnect to the network once I exit the garage
I just called Google support 10 mins ago about this and they went through normal protocol to reset to factory settings. They then called Tmo and let them know what the issue was while I was still on the phone. Tmo unregistered my phone from the network while my battery was taken out of my phone and then reregistered my phone to the network. Tmo asked me to monitor this for a few days and call them directly (not Google) if the issue persists. They will then elevate this to a higher level because they feel this would be a network problem, and not a hardware issue.
Hope this helps! Please post what you have tried to solve the problem!

^ it worked! my phone reconnects to the cellular network after what Google/Tmo did for me on the phone!
I haven't tried calling tmobile, but it is NOT something that will be fixed by hopping on cyanogen's rom. I've been rooted on cyanogen's rom for quite some time and this problem still exists on my n1 which is SUPER annoying. I will try calling tmobile to see if they can fix it on their side, but rooting is not the fix here.
I had the same issue. I used anycut and phone info shortcut and changed the wireless default setting to us and it totally fixed the problem. Have not had that issue again.

I resolved this by going to the T-Mobile store where they replaced my SIM card. They made a copy to a new SIM card, installed it and everything works fine.
For the record symptoms included:
* "Error while searching for network" message
* Found networks but said "your SIM card is not authorized for this network" when connecting
* Network listed as "No service" or "Emergency calls only | T-Mobile"
I get this too with an at&t phone.
Have asked for a replacement device from HTC (since the reception is crappy to begin with).
I also have audio quality problems when reception is only 1-2 bars.
Will see if the new phone is better.
I had this problem regularly. It hasn't happened once since I upgraded to Froyo, so I think it has been fixed in that release.
sometimes have this too, i fix it by going to the settings > wireless > mobile networks > APN. at first i deleted and retyped my password in the selected APN, now i just click my network in the APN settings, don't change anything and leave. It immediately reconnects after that.
edit: and i have stock froyo & live in belgium.
I got a new, replacement phone from HTC today.
This new phone has a BIG PROBLEM with this issue.
Even if I am only without reception for a couple of seconds (go through the garage, etc.) it will not connect to any network until I reboot.
My old phone would only experience this problem maybe 25-35% of the time.
Very, very annoying!!!

I had similar issues and called tmobile support. I was first linked to Google support. They went through the similar process as described by in the first page. (#*#*4636*#*# select USA band etc). While I was on hold, they called t mobile tech support and had them reset network connection and tried to get me onto a different tower etc.
Tmobile support stated that my sim card (had for about 2 years) was the cause of the issue as they can't handle smartphones as well as their new sim cards. They also said the new sim should improve reception and connection stability (Don't see how a new sim could do this but what do I know?). Moreover, they noted my account and told me to go into the nearest store for a new sim card. Went into the nearest tmobile store told them the issue, they pulled up my account and gave me a new sim. Took less then 5 minutes and I have not had the issue with staying connected to the tmobile network.
I will update this after a few days to see if I still have the issue.
I have the same problems that i cannot connect to network here in germany. first i think it was my sim card, but befor i had another provider (E-Plus) where i had the same problems with reconnecting to network. and one day my eplus sim card is broken so i had to buy a new one by t-mobile. i have tried a lot of roms from here (cyanogen/ 5.0.7 /5.0.8T5 Kangorama rodriquezstyle and leofroyo) everyone seems to have the same problems with reconnecting to network. i hope im not alone with my problems and someone can help.
hmm...
Count me as another. I just upgraded to froyo and it went beserk. Had no service for a while. It would only come on after constantly tapping "select network automatically" until it kicked me out of the menu. It started getting better but kept kicking me out of 3g. I set it to stay always on 3g and it seems to be better... still I'm going to call tmobile and see if I can get a new sim as well.
Thanks for the info guys!

[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] mobile network not available

Hello I'm having difficulties with my i9000.
The problem first started when I smashed my screen. Bought a replacement screen and middle plate frame bezel, including the home button flex cable. I also unfortunately damaged the loud speaker and thus replaced that also. Now everything is installed and the phone works great except for connecting to a network and making calls.
When I dial a number I get "Mobile network not found". When I check available network it finds my network and attempts to connect. Then I get a message this network is not available for this sim card, or something along those lines.
The sim card works in another android phone and other sim cards gives the same message.
The IMEI is intact and correct.
The phone is unlocked
I started on 2.2 and have flashed the firmware with many different types and still with the same message.
Now my question is this, how would changing the screen, middle plate & loud speak have this effect on the phone? Bear in mind that the phone still functioning with the cracked screen and making calls.
If anyone could help put me out of my misery it would be most appreciated.
Try flashing different modems now !
I'd say you might have disconnected a cable or forgot to reattach it. However, that might not explain that you do see the network sometimes. So yes, modem's probably a safe bet.

Ok I'll try this, not quite sure how the changes I made would effect the modem.

All cables have been checked and triple checked, and the network is always visible to connect to. Thanks for the advice I'll try the modem, is there a particular one I should try? I'm in the UK and my phone provider is 3.
Tried various different modems, giving sometimes better signal quality and sometimes worse. None of them have any effect. The message i get when connecting to the network is "your sim card does not allow connection to this network". Which to me sound like it may be locked again. So I'm going to try and dig out the original sim card and try that.
Try some other network and check !
Tried other networks and still no joy. I've flashed it many times now, gone back to stock firmwares and nothing will work. Spoke to Samsung and they just tell me to plug it in to Kies, which does nothing. I'll take it to my nearest Samsung service centre and see if they can fix it.
1. In security remove SIM pin request at restart.
2. Reflash MODEM with odin
3. At searching network check (automaticly)

Mi 8 - No SIM/WIFI, random reboots

Hello there
Long story short, I updated my Mi 8 (Global Version) to MIUI 11.0.1.0 before the update got suspended. A few weeks ago, my network provider had some technical difficulties, so I lost the signal a few times throughout the day.
A few days later it happened again, even though my provider fixed everything.
But this time I also lost my WiFi connection and I didn't get it back to work.
After rebooting, my SIM did not get recognized and my phone didn't want to connect to the WiFi network
After rebooting it over and over again for like 10mins, everything worked again.
But this issue occured every day since then.
A few days ago I updated my phone to MIUI 11.0.3.0 and the issue was gone for a day or two.
But now I am experiencing those things again, but this time it usually takes a few seconds and the sim activation service starts again and everything works fine for the next few hours until it happens again.
I will provide a full log later, hopefully someone can figure something out.
I really don't know whether it's a software or hardware issue, but losing signal and WiFi like every hour is driving me crazy and I'd like to avoid resetting my phone....
Oh and by the way, I don't have TWRP installed and it's not rooted or anything else.
Hi,
With me it happened exactly the same, I already paid to solve it and nobody has done it until now. I already lost hope of ever being able to repair
I've been having the same problem.
It's been incredibly frustrating.
[Update:] I went to a local repair shop, it's a hardware related issue.
For everyone else having this issue, try the USSD Code *#06#
If you receive an error, your Baseband Chip may be broken.
At least that's what I was told.
I have unknown baseband, did you replace the baseband chip?
if I put *#06# (no sim card in phone) it just shows up blank white pop-up with label IMEI, but no IMEI number or numbers or nothing else.
Mi8 no signal SIM/WIFI
Hello again
Same problem to my Mi8
When I tap *#06# show my MEID, IMEI1 and IMEI 2
Did you solve the problem ?!
Good morning. I have an MI8 MIUI 11, when I insert the SIM it recognizes it and disconnects itself constantly, the connection is not stable, when I turn on the wifi with the SIM on, the wifi is constantly disconnected and at times the wifi does not turn on, at some point too only the computer was restarted. When I take out the SIM the wifi works stable and well. Any idea of the problem ?? soft or hard? A technician told me that the problem is the display module, but they tested it without the SIM so I calculate that it is not the issue.
Yes, Hardware problem
Confirmed the problem is the baseband, but this cell phone model has the baseband integrated in the SoC (CPU, GPU, NPU and Ram) all one, it seems that it is a soldering problem
