Hi,
I've had my SGS2 now for around 2 months and thought it maybe be a firmware bug, but have recently upgraded to the latest via Kies which is KE4 and still notice from time to time that the my 3G just wont work.
If I try and access anything via 3G for example webpages you just get page cannot be found, but strangely enough what I have noticed the is H symbol will have a Green UP arrow active but nothing ever happens. In order for me to fix it I have to disable 3G via apndriod and then turn it back on again, as soon as this is done the 3G works as normal. Does anyone know of a fix for this?
I'm on the O2 network if that helps but I think its more than likely a bug with the firmware/phone.
Cheers in advance.

I've noticed it happen once or twice... but I just hold the power button, and then de-activate and then re-activate the connection from the popup menu. Sometimes when it has hung it can take a fair while to kill it after de-activating as well. But its literally only happened 2 or 3 times in the whole time I've had it; I've had catastrophic battery drainage more often which is a lot more annoying.
I've had the same issues on my phone aswell. I just got mine back from the repair shop and the problem still remains. The guys on the repairshop said it worked fine when they had it, but now its the same again. I dont know if it is my network operator who has problems with my phone staying online or what it is. But its damn annoying, I to have to disable / re-enable the 3G connection for it to start to work again.
I've yet to find a fix for this.. I'm on a network called OneCall, in Norway.
Any tips would be great
I had the same problem when I disabled fast dormancy.
Hello. Since about a week ago, I have this problem PERSISTENTLY. My phone is 3 months' old, I bought it new and unbranded from a store in town, and never rooted it. Only thing I did was upgrading the firmware through kies to the latest version available in my contry (KE7 if I'm not wrong). I have adroid version 2.3.3.
Well, I have found no solution to this problem that is absolutely unbearable.
I shall get rid of this phone as soon as I can because I am really annoyed by discovering problems after problems. I never had any iPhone, but I will try buying the iPhone 5 when it comes out. Hopefully it will work better. After all, it can't be so difficult to make a phone better than this one!
By the way:
I have 2 contracts with vodafone, one on this phone and.the other on a Nokia n95 8GB. Tried swapping the sim cards. Reault is that after the swap on the nokia there still are no problems whereas the SGS2 is still hanging on 3G and H.
So it isn't a problem of the operator, neither it is a problem of sim cards (also because they are different, one is 32k and the other is newer, and 128k).
Now, before throwing this absolute crap of a phone out of the window, I'd like to try a factory reset. But the question is: will I have to reinstall feom scatch every single app, after the reset? Is there a way to back up allbthe installed apps and easily reinstall them, without rooting the phone? I absolutely don't want to root the phone because I'm pretty sure I will end up selling it and so I don't want to loose the warranty.

Factory reset will mean you lost all data, everything on the phone that you dont backup.
But that might not fix it, your best bet is to try a newer modem, as its more a modem issue not a rom issue.
Thank you, veyka.
I just seem to habe found the solution! I disabled fast dormancy by dialing *#9900# (there's a hidden menu).
So far it's working great! It appears that my mobile network is not optimised for that protocol, therefore it must be disabled im.order to get proper internet connection.
So... anybody with this problem, try dialing *#9900# and tapping on "Disable fast dormancy" it is a fully reversible action (just in ca se...). Im fact, it cam be re-enabled at any time from the same hidde menu.
POST NOTE: No. This doesn't work. I spoke too soon...

This problem has been around for a while and I read somewhere that Samsung said they were working on a fix for it. I have had the problem from day 1 and it still does occur with Fast Dormancy disabled. I don't know if some of the newer Firmwares have fixed this or not. I am running official UK KF3 Firmware.
In fact, the fast dormancy trick worked only foe a short time. Now I'm back on wifi. What a disaster of a phone.
I talked to my network operator last night. They told me to go to settings->wireless and network->Mobile networks->Network operators and set it to manual, instead of automatic.
After this it seems like the problem wanished, but it might be just for now. Will test for a few days and come back to this!
Hey this is certainly a good suggestion! Maybe when signal is poor the phone starts searching for other networks and drops the connection. Good point indeed. I will make some trials as well.
Cheers

I was just wondering if anyone has had trouble switching from 2G-to-3G and back? I'm on Orange and once I'm on 2G it won't budge to 3G or H.
I know the signal is there as when I force the phone into WCDMA only mode it picks up 3G but if that's not available it's obviously not able to switch back down.
Update: Okay, I've done both a soft and hard reset on the phone, switched it to WCDMA and back to Auto several times, pulled the battery out to do a few cold reboots, selected 'Orange' as my carrier manually and I'm STILL not picking up 3G after I've gone down to 2G. I don't really want to flash my phone via Odin as there's no guarantee it will work and I don't want to lose updates via Kies.
Any idea that to do?
Update 2: Just re-flashed using Odin as per the guide and it still doesn't work.
I really don't know what to do now
Update 3: After all of that it looks like it was bloody Orange's fault! There is a fault with the 3G in Bristol which is forcing people to use WCDMA only for now. Hopefully it'll all be fixed by tomorrow and I nabbed a fiver off 'em.
I Have Asked My Frnd About your problem! my frnd hasnt yet faced any problem !
There are extensive threads in this forum regarding 2g/3g switiching issues or connectivity issues..try and search it, maybe yours is having the same problem.

Hi I am currently a T - Mobile customer and when I originally bought my Samsung Galaxy S2 with the company, I thought I could take advantage of using both the T - Mobile network and 2G services of the T - Mobile Orange Network.
However after successfully using it for the first 2 weeks, after my KE7 firmware update, I have an unbranded phone, it did not connect to the network anymore, stating, even if I manually select T - Mobile Orange in GSM mode only, Cannot registor with network, Unable to connect, then it states it is registered and yet I have emergency calls only stated and not either T - Mobile or even T - Mobile Orange. Then it will not connect to either network manually until I restart the phone.
I have since flashed my phone with various other firmwares, am currently on cognition s2 1.13, it's a great Rom, and still the same thing occurs.
I have contacted T - Mobile, they can't fix it, I have took the phone to a Samsung Repairer and they couldn't see anything wrong, stating it was a fault with Orange, as the guy in the shop's T - Mobile branded Galaxy s2 did the same.
Anyone solved the mystery, or is able to explain the issue to me?
It's doing my nut in, I have had phones like these for years, flashed them and enjoyed them, and usually work things out for myself, my last phone was an Samsung I8910, which was great with custom firmware support and I must say the Galaxy s2 is by far my favourite ever phone, but even my Samsung Omnia I8910 works properly on T - Mobile and Orange, and the latest and greatest phone won't!!
Have you tried flashing a different modem? Seeing as the cognition rom is based on I9100XXKG1, I know of a couple of forum members that have had trouble with the KG1 modem, and had to revert to the KF2 modem.
Worth a try? It won't wipe you phone of anything daft either.
List of official modems: http://forum.xda-developers.com/showthread.php?t=1131950
Before you do anything, can you dial*#1234# and just check what phone software is installed?
Thanks for the option Unfortunately I have tried the KE2, KE7, KF2 and KG1 Modems now, none of them have worked. It is really bizaar as the bloody thing works really well on T - Mobile, when there is coverage, plus the 3 and H is great speeds when they are in coverage, it just won't switch to Orange

one moment, I'm on t-mobile aswell.
text YES to 2121.
Homer moment: Doh, you cant text can you?
Just for reference, I'm with Orange and in my network list I have both "Orange" and "Orange and T-Mobile". I can connect to the Orange one fine, but not to the other one. It does switch to T-Mobile sometimes though. I've seen it do it.
Hi again, I have text yes to 2121, and it was working on my phone before. So yours has no issues then?

No, but I remember I used to have an everythingeverywhere app in data/private, which is no longer there.
I just texted yes to 2121 and now it lets me register on orange aswell as t-mobile.

Unfortunately if I let mine automatically switch network, it switches to emergency calls only if I am out of a t mobile network range, not orange, and it used to switch to orange no problem
Then when it is in emergency calls only, I have to turn it on and off to get it to work at all, as it will not register back to T mobile
My last attempt......when you go into wireless/mobile network settings, is data roaming ticked?

Yes it is, cheers for all your help. It's very frustrating and I can't fathom it out, so cheers for trying yourself
You don't need data roaming ticked in order to use Orange. T-mobile and Orange are both considered 'home' networks.
I'm on T-Mobile without data roaming ticked and it switches automatically to Orange without any issues. Might be worth phoning t-mobile up and seeing if there's some sort of issue with your account.
I installed Lite'ning Rom and found that I couldn't connect to Orange on my unlocked tmobile sim. Turned out that I had the "com.orange.authentication.simcard.permission" apk missing.
Downloaded it here:- http://www.contentsd.nl/apk/SimServicePermission.apk
and installed it with titanium and registered ok on orange.
Hope this helps.

Hiya guys. Sorry to jump on this thread but I am having the same issue as OP. I'd just like to give you an update on what I know so far. It is a nightmare trying to speak to someone at T-Mobile who actually knows whats going on, but I was persistent and got through to an engineer who said that they are having transmitter problems in east anglia and surrounding areas...not sure if you are in that area or not. Unfortunately all the engineer said is that they are working hard to a. figure out what the problem is ang b. fix it! He also could not give me an ETA and said that the only way to get back onto the network is to reboot the phone a couple of times. Not ideal, but I though it was something to do with the VillainRom that I flashed...so here's stupid me flashing stock, bricking/unbricking the phone etc etc only to find out later that its not the phone...on the plus side I have amazing battery life now haha who would have thought ey!
Anyways, hope this information is useful to you all.

It is not a ROM issue - it is a T-Mobile/Orange fault

Absolutely right Steph, it is not ROM related.
T-Mobile have acknowledged that there is a problem with registering T-Mobile customers on T'Orange cell towers.
I've been having this issue for a couple of weeks now (also in East Anglia), and after a lot of perseverance I got transferred to Level 2 support (Technical Support - not Customer Support) last Monday. They said there was a 'rectifier problem' on a mast in Henny Street, near Sudbury, Suffolk at the end of June and it has had a knock-on effect on other masts in the area. It was/is a level 2 priority for fix.
I wasn't happy with that explanation as it happens all over Suffolk!
Still with the issue on Thursday, I called them again and got straight through to Level 2 as they had marked my account as an on-going problem which Customer Support (in the Philippines) couldn't handle.
While explaining in detail the 'Your SIM does not allow you to connect to this network' problem the Guy I was talking to received an internal notification that they were aware of issues registering on T'Orange cells, that they'd known about it for 72 hours, have no idea what is causing it, and no eta to fix.
I've been using a forced connection to T'Orange for the last couple of days (poor T-Mo signal in house which always caused it to hunt for T'Orange anyway). Downside of course is that it won't get a 3G signal when forced into T'Orange mode.
Still happening today so need to give them another prod...
Oh, and I found this thread searching for answers - I don't have a Galaxy S, I have a Desire. Further proof that it isn't ROM related.
I'll update when I find out more from them.
Aaron
Just spoken to them again, problem is still on-going, they are still investigating and looking for more samples of the problem to try and isolate the issue. In light of that I would suggest anyone else having this to phone them and ask for Technical Support and register the fault - the more samples they have, the better chance of getting it resolved.
In other words, they still don't know what's causing it or when they'll fix it.
I've had this Galaxy S II since launch and everything was fine upto the first ICS beta firmwares, after that I just keep getting random no service which is starting to get annoying.
I've tried reinstalling older firmwares which didn't produce this problem in the past but it still happens and I've tried different modem files.
It's not signal strength as it's usually very strong.
Any suggestions guys? I could really use some help.
ive had similar issues on three uk.
My problem was my phone was picking up 2 cell towers and automatically connecting to the one that was furthest away, thus a crap signal all the time and sometimes nothing.
I solved it by going to the mobile settings, doing a manual carrier search where indeed three appeared twice, i tried them both to see which was the better one, then i manually registered to that one.
Since then ive had no problems at all.
I'm with giffgaff and I selected O2 manually, still getting no service.
Thx for the suggestion though.
Bump
Would like to sell this phone soon, so need it working normally.
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 .
jje
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)
Hello there,
I have been using Tesco Mobile with my Redmi Note 2 for a couple of months now and have had no problem. I decided to switch networks to a VPN called Life Mobile. They use EE's network in the UK. Since putting in the sim card today I have not been able to connect to the mobile network. I am wondering if anyone else on this network with this phone could help? I have called Life Mobile's helpline and all they wanted to do was run me through EE's apn settings. I had already used their app and also searched elsewhere on the web to find a few different APN settings but none of them worked.
One thing I'm wondering about if whether or not the custom ROM/firmware (MUI 7 I believe) that the phone shipped with (bought online from China by the way) is having anything to do with the internet problems. I get the feeling the customer service for Life Mobile were fobbing me off when they said that maybe my phone just isn't compatible with their network. Phone calls and texts work fine by the way.
Does anything think flashing the phone to the standard android ROM that's available would have any affect on the internet settings. I'm no mobile expert, and with the phone not being on general sale in the UK yet as far as I know, I would appreciate your help to get this internet/mobile data settings issues sorted, as I do use my phone for work.
Thanks in advance for comments and help.
I definitely know that the ROM that came with my phone from Gearbest was the worst piece of software that I have ever used in my life... ever. Check your MIUI build number and see if it's something like 5.xx.xx or 7.xx.xx. If it's something more like 77.55.66, then you have a knock-off and it may be eating your battery, performance, and experience (the original ROM Gearbest flashed on my phone had so much bloatware that the antivirus warned me about one of the programs every ten minutes, and heated up significantly on the home screen). If you have an unofficial ROM, try flashing a developer weekly or stable.
Hi all.
Well, would you believe it, I have spent a large part of the day trying to figure this out and finally I've done it. I'm not quite sure how but I've done it. I'll explain briefly to help anyone else who may be facing the same problem. It seems that changing the network preference setting within the sim settings from LTE to 3G did the trick. Life Mobile does not support 4G as far as I'm aware. That's no problem for me as I'm perfectly happy using 3G when necessary. After doing that and fiddling with the network settings, eventually reverting back to the automatic selection of the network as EE and using the APN default settings as given by the sim when it first was entered into the phone, things suddenly start to kick into life and we had INTERNET!
Thanks for your help in resolving this, and happy New Year to everyone.

Well, they sent me a new SIM card and I had all the same problems until I switched on "data roaming" and it now works fine (it didn't do anything with the last SIM though, when I tried it in another phone, I had to have date roaming on in order to even get a regular signal- data still did not work). I have seen transient "R" occurring when the SIM was activated/deactivated so had suspected this as a problem.
