Sorry
Hi,
I am sorry but I am new to this can you tell me how to know the ROM. BTW its recently upgraded to Android4.0.3...

Yea this is mostly because of tata docomo's ****ty network. The only way is to restart.
Go to select network operator and select TATA DOCOMO. It works sometimes . Not always

Press power button.... Activate flight mode then deactivate.... No need to reboot...

Hi @chintamanijaipuri,
I already tried this thing ..but it wont work..
I took it to service center they said its a software issue but after service also the problem still persists..this phone becomes boring without Internet..
Please tell me if it is network problem or any other issue...

I have attached a scrshot if u want to see the error

Go to apps, find the dialer app and clear cache and data. This will reconfigure you're data connection.

Do u mean this??
Hi Spydertracks,
PFA ... did u mean this app ..but options for clearing data are disabled ...

Go to APN setting and reset to default it will let you pick your network provider after. Then, if this doesn't solve it, find the APN for your provider and manually insert them.

Not working
Hi Braxos,
tried this just now..not working...

So it was working and all of the sudden stopped? Ymmv did you try to remove the Sim card clean it abut and reapply it? And if you have another Sim try that too.

usually works
Hi Braxos,
It usually works but as the network goes and comes back say while I'm driving after that it won't come back again.
all apps who need net will show "network not available" the 'E' sign disappears from the phone.
after I restart it, it starts working...
does the sim card has any effect on this...?

It shouldn't have! That indicates to a bad radio or network in your area. Suggest to try a different provider and see if the problem persists. And Sim can influence the reception if it doesn't have a good contact to the motherboards pins.

Thanks!!
Hi Braxos,
Many thanks for ur quick replies...
that means i can assume its not my phone but its the network who is the culprit...
will surely try with a diff network service provider and let u know..!!

No problem mate I hope it isn't the phones antenna and it is your provider/Sim card as you said you took it to a service center, and of your picture I see 2 from max 4 of the signal strength and assuming this isn't hspa! You should have at least edge speeds on it. Did you upgrade the firmware of the phone? Via kies! There was some firmwares with crappy modem.open settings go to about phone and post a screenshot of it plz
Thanks

Chk this scrchot attached..
I didn't updated it. i gave it to service center people they have done the upgrade..

Now open dialer and give *#0228# don't press anything just take a screenshot to see the mode of the network you are and the strength of the signal provided. At least for me the ics modem sucks, the lc1 on last GB German version was awesome.

WEIRD! Emergency call only! O_o

This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...
Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...
It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

JP5 (i tried another one, don't remember what version but it's the same, it is not firmware related)
in settings->about phone->status it says:
network: 3 ITA
mobile network type: UMTS
service state: out of service
mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...
i haven't tried another phone yet... will do now...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...
Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!
Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!
I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..
me too, has no signal at home but works for another phone.

[Q] Galaxy Ace some kind of network lock

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!!

If you bought it over the internet...try flashing it with the right firmware for the location where you are at...Perhaps LGE Mobile Modem or whatever it is called, like iPhone's baseband has a problem connecting to the network provider, due to the configuration or firmware. But in most cases the problem is in KISS- keep it simple silly...and from my experience it is the problem with the network provider or SIM. Try the sim card in another 3G capable mobile phone if it works o another phone that it is not the sim card. After that reset to factory defaults your Optimus 4X and put in the card. Do not jailbrake-root it. Just test it with the sim card. If that does not help, upgrade or reflash the firmware. If you need assistance. mail me.
I hope it helps. Good luck.
We have a SIM tool kit that might helps. It's one of the apps.

1st i tried every thing i know
i called my carrier (Vodafone) and they stated that it is a Mobile phone problem after we tried all troubleshooting they suggested including adding the APN manually and etc. then i contacted LG middle east to help me and they couldnt help either
finally one of the Vodafone technical team called me and informed me that this is a known issue from their side and we configured the APN with different type and it worked
similar problem!!
I have a similar issue as the original poster.
I got my Optimus 4X HD about 2 months ago. Everything was working fine until a few weeks ago (I think it happened after an update I got)..my phone would just randomly loses connection to the network (no data, no text messaging, no calling). I tried turning airplane mode on and off and also tried to have the phone search for networks and they didn't work. The only solution is to reboot the phone. This is happening at least twice a day... I tried my sim on another phone and didn't have any issues so I don't think it's a carrier problem.
I also did a factory reset but problem still persists.
My phone's software version is LG-P880-V10d-OCT-16-2012
Kernel version 2.6.39.4
Baseband version L6260_MODEM_SIC_02.1216.01
Build number IML74K
Android version 4.0.3
Anyone have any idea how to fix this without rooting the phone???

xperia zr sim card problem. specifically on (Globe telecom Philippines)

My xperia zr works perfectly while using Smart, talk n text, sun cellular simcards but doesn't work on any Globe sim cards or touch moblie (tm), this providers that i mentioned is from the Philippines.
I am certain that this phone is openline. I've checked it using xperia codes in dialler that i dont remember.
When I insert the Globe sim it only shows no service and emergency calls. But it shows the Globe provider in notif. I connot make call and text.
But when i use other network it works perfectly.
Is there any solution for this. Thank you guys. Im new here.
My phone doesnt have warranty anymore. :crying:
I am not really really sure as I haven't faced this situation before. Is there anything wrong with that particular sim card? is it possible to get a replacement and see if it works.
Someone in the forum might have better answers than me Wait before you try it out.

Sir thanks for your fast reply!!
Sir I tried different globe simcards, Sometimes it works but when signal drops to zero it remains no service and cant make or receive call and text. But I can see that the signal bars are working. But when I use other providers like smart,sun It works like charm ( , im on stock rooter 4.3 jellybean.
Good day Lervzz, try using gsm only as your mobile network. i'm using tm and everytime I use wdcma, my phone oftenly doesn't have a reception. This may be a problem for globe prepaid subscribers only.

I'm quite sure that I only encounter that problem when I'm using wdcma only. Why don't you try bringing your unit to a sony experia stall, they may give better info regard9ing this. The phone was launched June last year which makes me wonder why your phone doesn't have warranty anymore.

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.
