This is more of a question for very advanced users (possibly experienced in unlocking hundreds of phones with boxes like nspro or riff).
Very strange - the same unusual problem that I have seen now TWICE in two i9100 phones. Both from Orange (ORO) and unlocked I believe with nspro. Both were with older Android versions (4.03 or so).
The phones start OK and register fine on non-ORO network with their SIM. Calls can be placed and received. However after about 2 hours no new calls can be RECEIVED - the phone can still make calls, but when somebody else is calling it - the phone looks from the calling end like it is turned off or out of coverage area (or in some deep sleep of the modem). Once you try to place a CALL from the phone it works, and then the phone can RECEIVE calls OK - but only for another 2 hours or so.
EDIT:
The problem is present in both original 4.03 and latest 4.1.2 with any modem+ril combination that I tried, including the latest once from the original ORO network.

I have an unlocked unrooted S3 on Vodafone UK. This issue has been happening for the last few days whereby i have full 3G/H+ connection, but absolutely no data is working. No email, no websites loading, no whatsapp, nothing. The issue goes away as soon as I restart my phone, but then it comes back after a few hours.
Has anyone experienced this, and if so, how have you fixed it?
Go back to your network/phone provider .
Or flash different modem .

I am having this issue too. I may be wrong, but i realise this happens if i turn off my Wifi, the 3G will not want to connect to the 3G network.. Anyone else having such problem?
By the way mine is International version (Location: Singapore)
I'm having a similar problem where I have a good 3G/H/H+ connection but data seems to drop intermittently across all applications - I get the same sort of error message in browsers/facebook/twitter that you receive when you have no signal.
Anyone have anything similar and know of any fix?
I am not having such issue so far. I been updating my SGS3 using over-the-air update. I guess the MODEM has been updated as well.
Go to market and download "fast dormancy"(by gorkhanmoral) then disable it and reboot.
Check if your speed has improved,if it got worse then enable it again.
U need ROOT to use this tool.
I it didn't help, then flash a different modem
This is good modem
Cwm flashable

have you got any battery saving app like juice defender installed in your phone?
Is mobile data working at all? or is it constantly "uploading" but never "downloading" (up arrow lights but not down).
If what I just described is your issue then this is a network issue relating to android in general.
Basically your phone will be connected to two radio towers and gets confused as to which one it should use, rebooting or flight mode may help force it onto one tower or you may have to speak to your carriers "high network technical team" or whatever they are called for you to get them to force it onto one tower.
I had this issue on the HTC hero (a long time ago now) and it took 9 months for Orange UK to work out what was going on.

Congrats. Orange Luxembourg (my gf's network provider) still hasn't got a clue.. But they seem rather clueless about everything except writing invoices.
Flashing an Asian modem on her S2 made the issue far less prominent since they seem not to get confused by antenna ping-pong. (Tango Luxembourg, my carrier, has this issue too in the main city)
Hi All,
I searched but I couldn't find anything as specfic as mine so here we go
I recently restored my s3 (i9300) to stock DLJ4 4.1.1 from UltimaROM, it all works fine. The modem is DLID by the way. My phone is unlocked, and i'm on the Three network UK.
After a few days however, my phone suddenly switched to emergency calls only, however, the emergency calls never had signal and there was no way for me to recover this initially, so I left my phone overnight and by morning I had signal bars for emergency calls.
I also put my sim card in another smartphone to check that it was fine - it was.
So this morning I put the sim into the s3 and eventually, after searching for searching for networks, restoring default apns etc. I got the phone registered on 3 again. However this dropped out again after say 5 mins. So I repeated, and then after 5 mins it dropped out again. Which is strange...It is also worth noting that sometimes, when I scan for mobile networks to try connecting manually, upon completing the scan it will connect for this 5 mins period and then drop out again. Also sometimes it won't connect to the internet at all, no matter what i do, and this is where I'm at now.
Any suggestions. Could this be a modem issue - but I want to avoid this because I just made the effort of going back to stock..
Thanks in advance
Check for
Wrong IMEI
Wrong Modem
Wrong APN setting .

First thing I did - they're all correct as far as I can tell
You should ensure that the firmware is available for your phone.
I know there are least three regions producing the GT-I9300 phone. They are China, South Korea and Vietnam. However, a large amount of product from Korea and Vietnam has the software problem so the phone bricks and they are most found from Taiwan and this also happens in some users in China. They need to change the components which is made in China in order to solve the problem. I don't know whether this happens in your country as well. Fortunately, I never heard this problem occurs in Korean version(SHV-E210S/K/L and SHW-M440S) although they are made in Korea.
My girlfriend has had a Samsung S3 (I9300) for a couple of months and has had no issues with it however she dropped it and broke the LCD . I ordered a replacement screen (Front glass, LCD, and digitizer) from eBay and fitted this without any problems. I tested all functions on the phone and it seemed to be working okay. The same evening my girlfriend went and run the update and went from 4.0.4 (I think) to 4.1.2 since then she has complained about signal issues which I have now witnessed myself. I wished she had waited a bit longer to make sure the phone was working fine before doing any updates as now I am not sure if this is a software related problem or hardware. There is no way to revert back to the older version to confirm software. I know one option on the software side would be to root it and install a customer rom but I have never done this before and even though reading through the forums the process seems to be easy I am a bit reluctant to do this just now.
The signal indicator sometimes shows a circle with a line through it, sometimes it shows a grey triangle with no bars in it and other times it will show a bar or two and even a full signal. I have noticed even without a sim in it that it can show a couple of bars of signal. I have not got this confused with the Wi-Fi signal. When trying to send text messages or make a phone call the following errors come up “Not registered on network” and “No signal found for mobile network”
Below is what I have done/checked so far
I have restored the phone to factory settings but as explained before this will only restore to 4.1.2. This time the only apps on the phone are stock apps, no additional apps have been installed just encase a third party software may have caused issues.
Her sim will work in any other phone. I have an S2 and have ported my number over from a normal sim to a brand new micro sim to try in her phone. Both of these phones are on O2.
I have made sure the IMEI number is correct and matches what the phone came shipped with.
I have double checked the APN details and these match what my S2 has. Although I am pretty sure this is only for internet and MMS and would not affect SMS and phone calls.
After check over the settings and restoring to factory settings I have fitted a replacement antenna which I also got from eBay. I doubt I have damaged the mainboard as all other functions on the phone work fine. (Touchscreen, Cameras, Sound, Wi-Fi)
For some reason I can get the phone to work at my house on both GSM (2G) and WXCDA (3G) although it seems to be more stable when it is on GSM. As soon as I leave my house and go into town (approx. 2 mile away) or over to my girlfriends (approx. 20 miles away) it will stop working. I have gone onto the O2 website and entered both of our post codes on the O2 network coverage checker and this reports that there are no services down in our area and that we should have a good signal.
I have come on this forum for some advice and hopefully someone can recommend what I could do next. I have had a little browse on the forum already but is there something I have missed? Should I root the phone and install a customer rom? If it was caused by the official update is there an a hotfix of some sort coming soon? Or is this a genuine fault with the phone? If it is a fault with the phone and it has not be caused by me I could try sending it back to O2 (where the phone was purchased from) or Samsung seeing as I can’t see any warranty seals so think I would get away with this.
Thanks in advance for any responses I get to this and I am sorry if I have rambled on and provided info that is not essential.
Flash O2 stock rom via Odin .
If that does not fix it its a hardware repair job and you will be refused warranty as you have self repaired .

Hi all,
Like many others I had issues after the 4.3 rollout last week - lag on unlock, Bluetooth, general lag. But I noticed something else as well that I cant find an answer to. Prior to the 4.3 upgrade the phone displayed "EE" for the carrier as I was previously an Orange customer. But after the reboot the carrier information is showing as "T-MOBILE [email protected]@@@@@@@@@@@@@@@". The phone and data was functioning fine it was only the carrier name that seemed to be the issue (disregarding the other issues that came with 4.3). I went into the manual settings and searched for the available networks and could see Orange, T-Mobile, O2 etc but no EE. If I select Orange it still shows as T-MOBILE [email protected]@@@@@@ but when connected to my in-car Bluetooth it shows as Orange.
Screenshot attached.
I decided the best way to get rid of the lag problems and try and correct the carrier issue was to flash CM10.2 . Flash went fine and I held my breath as it rebooted......but no the carrier is still displayed as "T-MOBILE [email protected]@@@@@@@@@@".
I called Orange yesterday and they said from their end everything looked ok but they did send me a SIM update in hope that it would be corrected....but that didn't work either.
So now I'm at a loss with it - as I said phone functions fine and data is fine - but just an annoyance. Must stress it was like this before CM10.2 was applied and the phone was fully stock before I flashed it.
Any help appreciated.
Also - loving CM10.2 - quick, good battery life, nice features.
HI All,
nearly a week now and no sign of EE resolving the issue - is anyone seeing this issue since 4.3 upgrade - or am I just particularly unlucky ??

Reading that as a faulty update .
CSC may have changed your network name but above is not in any CSC i have ever seen .
Hey there,
I've had my S3 for almost 2 years now (So definitely no warranty) and around 2 weeks ago it started acting out:
Whenever I answered or made a call, there would be no sound (media players could work fine in the background but no call sound) and after around 30 seconds the network signal would drop and take a minute or so to reconnect.
Texts, Apps and general internet usage works just fine but buttom line i've been without a proper phone to make calls with for the last 2 weeks.
I've tried flashing CM11 Installer version (used to be stock) and that helped for like a day, then I got an advice to flash a new modem but that didn't help either.
I've seen that this problem happened to some people around the web about 2 years ago but haven't managed to find a single [SOLVED] thread.
So, does ANYONE have any clue as to what's going on or how to solve it?\
I would really hate to shed 300$ on a new phone right about now =P
Flash the latest stock firmware for your country with Odin, then factory reset before booting. If still the same then you have a hardware fault.

Hello,
Were you ever able to find a solution for your problem? I have a customer who is complaining of the same issue(s).
She said that she is unable to make phone calls or send SMS messages while on Data (2G, 3G, etc.), as well as her signal drops repeatedly.
I was hoping that you'd be able to assist me if you were able to find your solution, as I think the next step would be a hardware (Antenna) change in the phone itself, if it isn't the software itself that's the issue.
