[Q] PLEASE HELP! Phone loses service when it is locked! - Galaxy Note II Q&A, Help & Troubleshooting

I am having problems with a Samsung Note 2 that I found. I thought it was my lucky day, but when I put my SIM card into the phone, the phone works and has service and I can receive and make calls. However, for some reason, when I lock the phone, the service just dies out and I have to unlock the phone and wait a few seconds to a few minutes before I get service back and can use the phone again. Please let me know if anyone has experienced these kinds of problems before and/or have any solutions that might work.
P.S. I'm not much of a phone techie but I spent a whole day rooting the phone, adding CWM, and adding the Jedimaster-X ROM on the phone, hoping that this would fix the problem but it did not. Any advice or help is wanted! Thank you in advance!

I haven't tried it with wifi. I just know that the service bar goes from having 4 bars to a crossed out O right after I lock my screen. I can see the crossed out O when I re-light the screen by pressing the power or home buttons. I have tried various SIM cards and still no change. I also tried changing the ROM, no change.

1.93 ROM cant find any network

I recently updated my ROM to 1.93 with Radio .05 and now my phone is not finding any service, it just has the ! mark on top. I went into connection settings and used both manual and auto settings and it cant find my t mobile network. I am using T mobile in the US and was wondering if any of you had any suggestions. Thanks for your help

hi,
did u find other providers or is the list completely empty ?
try the following 3 points of success
1)just try whether you can make a emergency call
2)hold your diamond to a speaker in your near and listen whether there is a strange noise(turn on the speaker loud)
3) if you had another pda try the sim in the device
post the results....

thanks for the reply bro
in my area, t mobile and AT&T show up as networks but my phone will just not connect to them, its just says "searching" and stays that way
1) is 911 the only emergency call you can make cuz i really dont wanna get in trouble with the law you know haha
2) i do hear a strange noise when i turn the volume up
3) i put my sim in my old n95 and it works just fine
its like my diamond is not even detecting my SIM card, i put my friends AT&T SIM in it and it doesnt detect that either

Okay ill take a look at that, and yes I can choose between Auto, GSM, and WCDMA. I usually leave it on auto, but even when I switch to GSM it does not pick anything up.

holy potatoes i dont know what i just did but it worked!!! i put the SIM in my old N95 and it found the t mobile network. i sent some messages, made some phones calls, then put the SIM back in my diamond and it found the network!! wow thanks a bunch for your help bro, i cant thank you enough
okay scratch that it worked for a little bit, until I started installing some apps and had to restart my phone, now it cant find a network again when it booted back up. Is it the apps that im installing that might be causing this?
no man i dont think so...
i think that was a mistake by the sim or by tmobile self (i think if they have any problems, they didnt say anything to their costumers )
if you have the possibility to go a little bit away from your home, for example into downtown then do this and test if u get there a signal.
i live in vienna - austria. vienna has 23 districts - when i had this terrible problem - at least in 7 disctricts i became immediately a signal and in my own district i became to no time a gsm signal (or more accurately described - i became a gsm sigal after 5-10 minutes waiting time (every time i turn off and turn on the phone, always i had to wait about 5-10 minutes) then i could make calls but no internet connection was possible. but in the other 7 disctricts where ive been, all works fine

thanks for the help man your awesome, i really appreciate it. but i think ive finally found the issue, when i restarted the phone it couldnt locate any network. but then i started to charge it and boom!! it found it again! so does the battery need to be near full for it to locate a signal? haha wow, craziest phone ive ever had!

thx - i do what i can
but i dont think that the problem is gone - you will see - it wont work long. i signal must be there - it should does make no matter whether the battery is - not load - half load or full loaded. it must always work! at 1% of battery it works on my device - it is impossible that that is the problem of you. go to the next tmobile store and let change your sim card - or make it like me - just wait 4 days - hope tmobile have fixed their problems - and be happy if it works.
otherwise it was a hardware issue and you have to send it back to tmobile for repair. but if you do this you must restore the stock software... otherwise you lose your guaranty!!

oh i forgot to say in the first post that my diamond is unlocked, im just using t mobile as my carrier on it but my phone is not locked to any network. so im not sure if its t mobiles fault but just my phone. My SIM card worked fine right away when i put it in my N95 8GB, but my diamond did not pick it up right away when i put it in. I had to plug in my charger first then a few seconds later it found a signal. Not sure why it did that, maybe just needed a little boost to grab that signal or something. Could it be the ROM or Radio I am using?

ok, then send it back to htc, or bring it to the store back where you bought it.
but do this only if you really see no more chance to fix it...
remember what i write, i try my sim in a nokia 3310 and it works, a few seconds later in diamond and 2 other pda's i got no network - back in nokia and it works i dont know how this could be possible!!!
i also try 5 different roms and all radios that exists too - and with all was the same - just nothing.
its your choice my friend - be patient and hope for better times or send it back to repair. but then also upload the original htc rom, radio and spl
i go now sleep - at vienna its 23 o'clock iam verrrrrrry tired from a hard working day...
but post further results, i read it tomorrow...

same here
i have a very similar problem.
i can only make and receive calls on the wcdma network, but not on gsm.
in both, it says that i have reception, but when i try to make a call it just goes silent and after a while the call is ended.
if i dial *102# which is the number to access your mobile credit status, on wcdma it opens a little bubble coming from the network icon and says the correct values, on gsm it simply waits and says connection interrupted.
i have tried several roms and radios, and the problem persists...
you can view my current setup in my signature.
any ideas, what could be the problem? is it the hardware? does this have to do something with hungary?
the sim works just fine, since 1997 (i have no idea how can 3g work on this little baby, but it does) =D
any help appreciated! tx

hi,
i was really wondering why this strange problem happens now on more and more users... thats really interessting....
did you try the sim in a other phone?
if it there also not work -> go to a store from your provider and told them that u have a old sim card which not works with your current phone.
normaly they should give you immediately a free new sim card.
and please tell me whether you have tmobile as your provider.
just for info because you write, that u can use 3g.... when i recieved my diamond i also had an old sim card which doesnt support UMTS or 3G but HSDPA was working, that cause because the sim is not responsible for this communication mode - only your phone!
the problem the guy has in this thread is almost exactly what i am experiencing right now
http://forum.xda-developers.com/showthread.php?t=409733&highlight=network+problem
except mine used to just keep restarting an wouldnt boot up so i just let it do that for about 10 min and it eventually loaded up. Is there a specific number I can dial that will reset my SIM card settings or something? My phone has been like this for a couple days now and it sucks not being able to call or text anybody.
I thought I solved this problem when I plugged in my charger to my phone, then it started finding the EDGE network but my signal was still being dropped when I made calls, only some text would go through and thats it. Please guys, somebody save me from this misery!

Okay, nope not fixed... Flashed it with 1.37, connected to the network for a few seconds, dialed somebody and no ring or anything, but when i called my phone i could hear my own voice. So I guess i have to send it in for repair. Damn.

at this bad time i also restore to stock rom 1.37 and he found in 1 second a signal BUT then it was also impossible to make an internet connection...
ya i was starting to think it was tmobiles problem until I put my friends AT&T SIM in and it was doing the same thing. It would just say "searching" and thats it, and well I just charged up my phone to almost full battery and it located a signal again. But it still drops calls almost immediately and I can only send text. Does the 1.93 ROM do anything to the Radio or antenna because it has been like this even when I flash back to earlier ROMS and radios. I am almost sure that flashing or changing radios will not solve the problem because I have done that countless times already.

Phone keeps reverting to Emergency Calls Only

I'm running MIUI on my UK Desire Z, on a T-Mobile pay monthly contract. The phone frequently goes into Emergency Calls Only mode for no apparent reason, then goes back to normal in a couple of minutes.
Has anyone else had this problem?

I have not had this problem, but I believe that once the phone goes into Emergency Mode, it should require a battery pull and/or a reboot to return to a normal state of operation. Perhaps try a battery pull? This is supposed to be a security feature so that if something happens your location can be tracked... or so I've heard.

That's the strange thing - it rectifies itself after a minute or two WITHOUT requiring a battery pull or any other kind of intervention. I'm just wondering what puts it into this state in the first place???

I think it may also be a sign of a bad SIM card. Actually yeah, I don't know why I didn't think of that first. If it were me I'd try a replacement card and see if that resolves it.

Trying a "replacement card" sounds easier said than done. Do phone companies issue replacement SIMs without the need to port the number from the original SIM?

Yes. SIMs go bad from time to time, and they can easily issue you a new one (keeping your existing number). Not sure about UK, but in the US, the easiest way is just walk into your carrier's store, and they can fix you up. Some carrier ware technically supposed to charge you $10-20 for a new SIM, but they will often overlook it. Really, the things cost close to nothing. And the SIM simply enables you to use their service, and for them to make money off of you. So why not give you one for free?

The phone moves to 'emergency calls only' intermittently when switching networks or turning in/out of airplane mode, etc.. if its staying in that state, your phone is either having trouble keeping network connection, or isn't properly registering on the network. Id check to make sure your APN's are correct and if they are then id go about replacing the SIM possibly.

Have the same problem, but need to reboot my phone to work(( Have no idea except bad SIM-card. But it's registered to the person I've never known, so I can't change it((
I'm having the same problem in uk on orange (signal sharing with tmo).
As I wright this I have 1 bar but says SOS. Bam.... 2 bars orange. It seems to be when it would normally switch to tmo. Been like it for 48 hrs now.
I'm going to give it another day or 2 then investigate further if needed. Could be they are doing network maintenance.

it might due to soft bugs or sim or singal issue. Need more info for investigation.

[Q] No Network Access on Galaxy Note 2 ATT

Hello my name is Stanley, I recently bought a Galaxy Note 2, I'm from the Dominican Republic so I'm using Claro Dominicana, which uses the same baseband as AT&T, basically instead of the signal bar, I get a circle with a straight line on it, I don't have data, I can't make calls, I can't send sms, when I try to call I get no network access message, I believe it does recognize sim because I don't get any type of error when my cellphone boots up, when I bought this cellphone it wasn't rooted, so I decided to root it and flash a rom, I'm having same issues.
Can you guys help me out please? I already have my APN information but it's not helping, I've tried flashing roms and it's not helping, I really don't know what to do, when I first bought it, I tried my sim out and it did have internet, I decided to do a factory reset through settings menu and after that I haven't been able to get any type of signal, I would deeply appreciate your help guys, I'm getting kind of desperate here.
No signal bars means no modem or a sim card for a dead account. Did you pay for any airtime?

I did try it, I'm pretty sure is unlocked because it was just working before factory reset, I guess I can try to do it again, but I'm pretty sure is unlocked.
I tried several roms and modems and nothing worked, the last thing I did was going back to stock through Odin, but I still get same circle with the line on it, a stop sign, right now I'm on 4.1.1 stock..

i don't know if this might be an issues or not, but check your IMEI. T-Mobile webpage has a method to confirm if it been blocked or not.
http://www.t-mobile.com
As of August 8th of 2013, they've re-designed their webpage.
http://www.t-mobile.com/bring-your-own-phone.html
following that link, scroll down until you see this: "Don’t see your device?" and under that, a search box. click on the link below that search box. it'll bring up a screen within the webpage. input the IMEI from your phone (*#06#) and avoid adding "/ ##" as those aren't part of the IMEI. If it report as stolen, chances are, they probably blocked it. If not, then maybe your provider doesn't support the phone itself. you might have to call customer service from your area.

I couldn't find information about my imei using that webpage, it wasn't able to locate it, I used this webpage which said is clean http://swappa.com/esn I don't know if that page is good, but it says it's clean and ready for activation.
Try a friends sim card to rule that out
If the phone worked on your network before you rooted and flashed the new rom, then I imagine you must have flashed an incompatible modem. If you flashed stock back via Odin and that didn't fix it, I'm scratching my head. Try stock again. Then remove and insert the sim or toggle airplane mode. If it worked before, stock should fix it.

Hello guys, in this case it was actually a hardware problem it seems that the internal antenna of the cellphone which receives the network signal was damaged, I'm already getting it replaced, I'll let you guys know the results.

Do you know what was damaged. Is it the wire connecting the USB flex or is it the antenna built into the back housing?

[q] samsung galaxy note 2 serious issue

Hi everyone. I bought a galaxy note 2 from a friend two days ago and now I cant make calls, use 4g data or send/recieve sms, everything else works (including wifi), let me be as clear as possible as to what happened.
I purchased the phone from my friend 2 days ago and it was working fine. its a Telcel (mexico) galaxy note 2 N7100. I tested the device fully and everything was working, I made calls etc and data was wotking also.
I took the phone home and used a soft damp cloth to wipe the battery cover clean, it was greasy and all note I removed the battery cover from the device. Afterwards I replaced the battery cover, connected to my home wifi and then there was a message on my phone "set up software update' which i agreed to .
I then switched my sim card with a different one( it had call credit on it). and upon powering on the phone, i was greeted with a screen with a small padlock and the words "SIMLOCK". i swiped up and bypassed that screen. MY PHONE WAS SHOWING 4 SIGNAL BARS BUT UPON TRYING TO MAKE A CALL OR SEND A TEXT MESSAGE, I keep getting error messages such as "NOT REGISTERED ON NETWORK".
I have tried every single thing to get rid of this. I even purchased galaxsim unlock from the playstore and it claimed to have removed the simlock but i kept getting that screen with the padlock and simlock message and also no calls or text can be send or recieved. I tred different custom roms, official roms, I tried flashing different kernels, modems etc you name it and still I cant use my phone.
The phone was on android version 4.1.2, now its on the official/rooted 4.3. I read online that samsung may have region locked my phone but this is very strange because my friend was using it for several months. and the issue arised when I took it home. I have never given up on an android device EVER. I have spent days trying and succeeding in unbricking phones but for the first time i actually feel helpless.
I have used so many samsung devices befoe including a galaxy s4 from europe without any problems.
Lasty even when there is no simcard in the phone, THE PHONE IS SHOWING 4 TO 5 SIGNAL BARS ALL THE SAME, IS THIS NORMAL??? also the phone detects the simcard, i can see my contacts etc. The phone can search and detect available networks also but when i try to connect to a network manually it fails to do so, or sometimes it will connect but i still get that message saying network not available.
also the phone only allows emergency calls, but when I try to to dial emergency it says OUT OF SERVICE AREA. Someone please help me if you can

Hi everyone. I bought a galaxy note 2 from a friend two days ago and now I cant make calls, use 4g data or send/recieve sms, everything else works (including wifi), let me be as clear as possible as to what happened.
I purchased the phone from my friend 2 days ago and it was working fine. its a Telcel (mexico) galaxy note 2 N7100. I tested the device fully and everything was working, I made calls etc and data was wotking also.
I took the phone home and used a soft damp cloth to wipe the battery cover clean, it was greasy and all note I removed the battery cover from the device. Afterwards I replaced the battery cover, connected to my home wifi and then there was a message on my phone "set up software update' which i agreed to .
I then switched my sim card with a different one( it had call credit on it). and upon powering on the phone, i was greeted with a screen with a small padlock and the words "SIMLOCK". i swiped up and bypassed that screen. MY PHONE WAS SHOWING 4 SIGNAL BARS BUT UPON TRYING TO MAKE A CALL OR SEND A TEXT MESSAGE, I keep getting error messages such as "NOT REGISTERED ON NETWORK".

[Q] Very bad service, not able to update, doesn't recognize other simcards

Something really weird is going on with my At&t galaxy s3. I'm new to this forum so I'll just explain what I'm experiencing and do my best to work through it will all of you. This phone got rooted by someone else and when I got it, the rooted program was in chinese and was acting all weird and wasn't getting good reception, although it was before it was rooted. I flashed it back to normal and it's acting very curious. It will receive an At&t simcard but the service bars will go from 1 bar to 4g to Edge to 1 bar all in a matter of 20 seconds or so and doesn't seem to work. It will occasionally work to send messages, make calls, but it seems like it can't ever receive calls. I checked and the IMEI number is still the same. Also, I had originally tried to unlock it to another carrier and when I put in different simcards (From other carriers such as verizon) the service bars don't show up, instead, all it shows is a cancel sign and doesn't ask for an activation code or anything. I'm honestly not sure what to do here, I thought I had broken the simcard reader and replaced that, but that made no difference. I'd greatly appreciate any help. Thanks!

Unlock is supposed to be permanent so it's odd that you lost it.
Now as for your problem, a lot of people are getting this issue lately, where unlocking damages their nv file. The solution can be found here: http://forum.xda-developers.com/showpost.php?p=43842387

Thanks for your quick response I have been looking for a long time and never saw this issue before. I'm not sure where I'll be able to find a replacement nv file...but i'll see if anyone I know has a galaxy s3 from at&t. Maybe once I do this the unlock issue won't be messed up anymore.
