Download the firmware for your region, the correct one, and flash through odin.
Hope you have flashing knowledge. and that will fix the modem issue.
thx my friend .. ya know how to flash with oden ... one more Q is my problem in the modem 100%?? can the problem be in the hardware?
i was in the Official GB 2.3.3.. is it the same thing or i have to try this one also?
Modem can be the main problem if you dont have signal at all.
But even after flashing the correct rom and modem for your location and you face the problem there could be chances of hardware, very rare though, or could be the area your living at, far away from the city or maybe some area that dosnt fall under a proper network coverage.
could be anything. Just flash the correct firmware rom modem whatever, check that your at an open good place, call and message your friends and check for network problems. Hope this helps.
thx friend.. there is a signal but weak and NOT about the aria i live in coz my brother has HTC with the same network nothing wrong also my sis has Nokia n8 with the same network company also nothing wrong at all clear sounds receiving and sending not as my cellphone many problems with sending and receiving sounds i hear them clearly but they barley hear me and sometimes the line goes off!
this problem is killing me.. plz help
up up up up up
you're wiping cache and dalvik cache in recovery before flashing these modems? also, don't plug your charger/usb in while doing it; it's known to cause zero signal when flashing UCKF1, even though it would work otherwise.
Also: you could try entering service mode and checking your settings there.

Oh, I linked to you the wrong post in that thread.
http://forum.xda-developers.com/showpost.php?p=9201884&postcount=2
First one, for signal -- choose menu items by the numbers like he said.
Also find out what bands your network uses (both for calls and data) and make sure you have the right settings -- they likely should be; they'll be in that services menu.
Sorry, figuring this out will take you a lot of searching, reading and playing around. Just note down what you do so you can go back to it if you have to.
man i did what he said and there r 1.8.3 but 6 not there in my menu there r just 1.2.3.4.5 ... 6 is not there????????
up up up up plz help
:'(
what should i do?? i'm going to throw it
Please try your SIM card in any other cell phone (eg. your sister's). If it has the same weak signal then it's possibly the card that is caussing all your trouble. I heard of similar problems when people received new SIM cards from providers because of network issues. I don't have any idea what a SIM card has to do with signal strenght but that's just what I was told.
If this also doesn't work then it might be your hardware.
nothing works :'(

Try flash a stock firmware let it boot and see if the problem persist, if all is OK then flash back to your preferred rom.
@intratech has a lot of roms,modem and guide, search his thread

Hi everyone,
I recently got a kaiser phone and tried to unlock it.. I'm not sure if it worked.. but then I tried putting a regular at&t sim card and it doesn't get any signal.. What do I do.. I did install the new rom for it.. Maybe I should restore it to the orgininal rom that came with it.. (anyone has the old rom that comes with the phone when it comes) I can try to call and see if they can send me another one.. Or what should i do. I put at&t and get no signal.. It keeps telling me search for network.. HHHHHHHHHHHHELLLP. I paid 420 dollars for the phone and I really don't want it down the drain.. I will donate to anyone that helps me fix. it.
Please specify everything better. I cant really tell what version you have what you installed and what exactly happened .

Have you set the phone (under settings>phone>band) to Auto sellect the phone band? If not it may be trying the European frequencies.
Just set the bands to auto and then select GSM and then it sould be fixed, if thats the case .
I recently got hands on to my friends Galaxy Ace, who complained that the phone is locked.
When inserted SIM card and dialed, got error "network not available", but the phone shows signal bars.
When dialed *#7465625# to see network locks, it shows that all locks are off?
Any ideas? Should I root the phone?

Root aint gonna help u in anyways!
Check Your Friend IMEI ... *#06#
If Shown only 0000000 at your friends IMEI ... you got your self an expensive brick!
If not try with other sim card ... if all locks are off, phone is unlocked for sure! you could have a modem problem
It shows phone full IMEI code.
OK try this,
go to settings > wireless & networks > mobile networks > network operators
once you tap on that it will search and find all the available operators choose the one that is yours or try some others. My friend had same kinda problem but he is in another country and well this is the way he managed to solve his problem. so try it. and if I helped press the thanks button thank you.
Good luck ;-)

you have two more options either try a different network as said above or change your ROM. if those don't work then its a hardware error. which unfortunately we cant do anything about it.

it depends on what you would expect from a ROM. performance or battery life or look or ...
here r my suggestions:
miracle edition v4 (performance is good so is the battery life and its ics themed so its at the top in my list) >>>I'm a link ;-)<<<
Jusada's ORIGINAL ICS Final (performance really good and battery life is good and its ics themed but you may run into stability issues if you over clock and use the phone continuously. but overall its cool also its got cool transition animations that most other roms don't) >>>I'm a link ;-)<<<
or you may use the official cyanogenmod ok? let me know if you need any help with flashing roms. ;-). In additions if I helped pressing the thanks button is the way to help back around here.

Hi RaidoRi, did you ever manage to find a solution to this problem? I am experiencing the the exact same issue - I am trying to get a Swiss Samsung Galaxy Ace GT-S5830i phone+ Mucho (Swiss) SIM to operate in Canada - I HAVE to get it to work for a personal reason... I also have "Network Lock is [OFF] after dialing *#7465625# and I have a full IMEI (not just 000's).... The network that the phone selects automatically does not work with the Swiss SIM ... (The phone only works with "Rogers", and the Mucho SIM will only work with "Bell Canada" - because that is the company that Mucho's parent, Swisscom, has an international relationship with). Do you have any idea how I can get the phone to work and make my Swiss SIM card work here? I have been trying everything for over a year now but cannot seem to find a solution (the latest attempt was asking a friend from Switzerland to mail me a brand new phone and this is what I am now trying to unlock)... Other phones in North America will not recognize the SIM card at all...
Sorry if this is confusing but if anyone can help I would greatly GREATLY appreciate it, and I am sure by now you are all aware that I am not a developer so sorry if my question is kind of all over the place.
Thanks in advance!!
Hi Team,
I have heard lot about this forum and hope to get some gud suggestions from you guys.
I bought my Samsung Galaxy ace GT-S5830 with android 2.3.6 Gingerbread OS 6 months back but slowly I started facing few problems when my friends noticed and told me that your phone sometimes says switch off.
I also realized that sometimes even if the airtel network is there still i get an error message that mobile network not available I had to switch off the phone to get it normal.
Again people text me but it goes on pending and gets delivered after hours. I showed this problem to the service center they flashed my mobile but the problem persist I also tried changing my sim card but still all in vain. Now i am literally fed up with this phone.
Please assist me I dont know wat to do :crying:
Note: The phone is not rooted.
Thank you
err, are you sure this is because of the phone..? not the network..? because i never face any of the problems you mention..
may be you should try flashing stock rom with newest baseband for your region, find it on sammobile..

He said the service centre guys reflashed the rom. but agree that the sms thing could be network problem.
Faulty battery/pins (Switch offs)
Faulty hardware (Antenna?)
That's all I can identify.
Hi Guys !!!
Thanks for sharing your views
@demiorkan
The mobile automatically does not gets switched off but i need to do it manually as it keeps on prompting the error message "Mobile network not available" though I can see full network on my mobile.
I would really appreciate if I get any suggestions from your side.
Let me know if any more information is required.
If you dont mind you could try flashing another stock rom and see if that works out. If it did not, then it's probably a hardware problem OR the network (as mentioned). Try your SIM card on another phone as well, that should prove if there is problem with the network or not.
Mostly it might be a firmware problem. Service center might not have flashed a new firmware but simply wiped and gave back. (can't be sure on that). So I recommend on using ODIN and flash new firmware. Google is your best friend on this.
Secondly about the network, Turn on flight mode once and turn it off, you'll get the signal. You can even do some debugging by going to the testing menu (*#*#4636#*#*) and toggle the radio and the preferred connection type and stuff. But if the place where you are is such that you get low signal, then don't try any things on phone as it's ultimately the network problem. Trust Me, the place where I stay, I rarely get proper reception and Even I'm on the same network. Flight Mode trick saves the unnecessary reboot.
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!

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?

Flash full stock ftf and try again
I tried but it didn't help. Any other suggestions
guys please help me out with this, it is very irritating
Try to keep your phone in 2g only mode. When i keep 3g only only mode i sometimes can't receive call from other party. But 2g only mode solved my problem....
Sent from my C6602 using xda app-developers app
How do I shift it to 2g mode?
menu->settings->more..->cellular network->network mode-> Only GSM
PS. type: *#*#4636#*#* and check in "phone info"
signal strength
GSM service(if enabled)
In old galaxy spica I had similar problem and I had disabled GSM(dunno why) and after second full flash of fresh stock ROM It was working again.
its not helping
I tried everything possible.
So maybe we start from beginning...
Few quick question before we can help you:
1. When those problem started?
2. After what? did you flash custom rom or Kernel ?
3. You had any app/script that could modify your phone?
4. You had ANY hardware problem before?
5. Your phone fall to the ground?
6. Did it have any contact with water?
7. What system do you have now.
8. did you check sim slot?
9. do you have signal strength in this menu that i post earlier?
1. This problem started a month back
2. It all started suddenly, I am on the stock rom without root
3. No I dont have any app that can modify my phone
4. Yes I had a faulty battery problem which was fixed
5. NYes once it had but it was a long time back before the problem started.
6. No it did not have contact with water
7 I use the stock android 4.4.4 kitkat
8 Yes I have checked my sim card slot, I have also replaced my sim a couple of times
9. Yes I have signal strength -79dbm and 25 asu
My sim works well with my other phones. Is it a hardware issue?
I think Im getting a clear view of the problem, my phone isnt able to shift from 3g to 2g I guess. I came to this place where only 2g works, I had my network mode setting as Wcdma(preffered)/gsm, its reluctant to shift. Is it a hardware problem?
Hmm.... If you have signal and phone see network its not hardware problem. To be honest its more like system or more specific kernel problem in 4.4.4 I say this because you ares sixth person who i know that have network problem in 4.4.4
For examle after flashing kk on my phone i have looooooots of reboots if i have 3g network on, and my phone swith to 2g if its in sleep mode.
My friend also have problem similar to yours but it cant use phone function if its have LTE enabled.
Best part is that when he flashed 4.3 problem is still there, but he didnt had it before when he had 4.3
I cant flash any other system now(i use phone too often )so i dont know if i also would had this problem...
So if you can, you could flash even 4.2/4.3 full clean rom and check, just to be sure. Its a bit "extream" downgrade but flashing it and checking its max 1h...
Probably like always its small weird bug or specific system setting problem, maybe different region rom...
So for now you could check other rom, even branded and downgrade to your old 4.3 to see if you still have such problem.
Seriously its a relif that its not a hardware problem yet.
I also flashed the lower version of the kernel. I am facing the same problem . I use the local region ROM only,
I think Im gonna give up on sony now
Hi there
You are not alone, I am also facing this issue and do not know how to resolve it too.
Sometimes when I try to call (full bars on) it makes a bipbip then Call not possible...
Same issue while switching from GSM to H... Most of the time I have to reboot and let it settle for a while.
I am suspecting my network provider
Sent from my C6603 using XDA Free mobile app
I called up the service provider, it seem to get fixed for a day but again the same problem continues
I'm tired of this, the phone guys can't do anything and neither can the service providers
Such an irritating bug by sony
Did anyone get a solution to this problem?
This is very annoying
Same problem,posible solution temporary.
