Hi there everyone.
I have a Samsung Galaxy SII. I live in Australia, have an unbranded phone, and am currently with TPG as my phone provider.
I have been experiencing these problems for a long time, and after trying to figure out what's wrong with it, it's time to ask for help. Haha.
These problems started after I flashed a new modem after installing a ROM. Previous to flashing, the reception had been fine. After flashing the ROM, and not the modem, my reception was still as good as it was when I first received the phone. However, after flashing a new modem, the reception dropped significally. Where my brother also with a i9100 could receive full bars of HSPA/3G, I could only receive 2/3 bars of G. Where he would have 3 bars of G (in our house, it has this stupid insulation that really nerfs reception), I would receive absolutely no reception.
I have tried countless modems (pretty much ever modem since K13, testing for reception, but never have much luck, maybe a 1 bar fluctuation up/down).
Do you have any ideas what could be wrong? How I could fix it? Thanks very much.
find the modem your brother have ,download it from the intratech and flash it
have you tried KE7?
I got a good expereance with this on Data speed, but I dont know about reception strenght.
go through discussions of this thread http://forum.xda-developers.com/showthread.php?t=1131950
He hasn't updated for a while, and is using the K13 modem. I have tried it, along with the K14, and KE7 already.
do a factory reset without the sim and sd card....
I tried factory resetting without the SD and Sim card, but it still didn't work.
Any other ideas? Haha.
Do you have i9100 or i9100t

The international i9100. The phone was originally bought from Vodafone, then unlocked with a code.
Mines vodafone australia and its a i9100t.have you tryed a t modem
Sent from my GT-I9100 using xda premium
I haven't, maybe that's the next thing I'll try. But does your box say i9100, or i9100t? Mine just says i9100. Haha.
Edit: Omggg I love you. Hahaha. I flashed a T-modem, and now I'm getting full reception. Thanks somuch!
Under the battery.if it does try the vodafone modem

Just wondering what the best modem is for ATT and some other question about modems.
Right now im running wanam lite kj1 5.6 with ICS domination theme. I have KI4 modem flashed because i was on villanrom which i might go back to because it has better battery life.
Does the modem affect the ROM in anyway? just wondering because most roms have a modem prefix to them on the development forum. or is there a certain modem better in every senario?
Thanks for your help!
I too would like to know the best modem for at&t. My current one (Current official uk unbranded) seems to completely lose signal after a phone call or just randomly, it quickly reestablishes connection but still annoying.

Have you tried Odin to push the uckj4 leak modem for the i777? All the 9100 modems I e used on my i777 turn the radio off when a voice call occurs then reconnects after call fails.

Maybe i9100 modems just dont work on i777 and vice versa. Hopefully someone could correct me but i guess its worth a try. Is it better to flash modems via odin then CMW? and another question whats the difference between a modem and a kernel? I know on some level the kernel has something to do with the firmware and the modem has to do with the baseband, but im still unsure about the difference.
Thanks again!
Also have the same problem. The 3g lost the signal randomly. my baseband is "UNKNOWN" . Any idea?

I'm assuming these guys are running real I9100s on AT&T (otherwise they're in the wrong forum) - pushing an I777 modem will likely completely break them.

Hey, did you ever find out the answer to this question?
I want to know what's the difference between flashing with Odin and CMW, is one do more than the other?

I'm on baseband XXKI3, running my I9100 on AT&T... don't have any issues. No call drops, no signal drops after calls are done, etc. Works fine.

Funny - I have XXKI3 as well on AT&T and periodically I get drops and it's almost always just as syncing is initiated.
@robsw
I noticed you are located in Chicago. the problem could just be that AT&T sucks horribly in the downtown area. specifically anywhere near River North or the loop. I have tried just about every available modem and I still have data connection issues in those areas. Even friends with iPhones comain about poor data in those areas.
I use the ki1 modem on my I9100 on at&t in louisiana. Ive found this modem gives me the best signal in my area. I did use ki4 for a while but i kept getting dropped calls inside my house. Now with ki1 no more dropped calls
Sent from my GT-I9100 using XDA App
I live in Champaign,IL. Data drop/hang issue always there on KG2, KI3, KI4 modem. I had data issues even I have full bar of signal. But I do realize that data drop issue is location related. Every time I go to the same place, I got slow or data drop problem. Ha! maybe something isn't configure nicely between the tower and our S2.
yea, I was in Chicago this weekend, kept turning on Airplane mode and back on..
at&t is making me pretty mad.
GT-i9100
4.0.3
Baseband version
I9100XXLPH
XXLPH Kernel as well.
I am in Colorado and my service is great. I dont have much experience with the GB radios because as soon as I got the phone Iw ent to ICS and never went back
It may be worth checking the sticker under the battery to confirm the phones version. In Australia, New Zealand, Israel and some other countries they also sell the I9100T which is just the same as the international version but works better on a T model modem. There are plenty of them linked in the Aussie thread in general.

I'm in the North suburbs. This most often occurs when I'm driving. The call will drop and more often than not, when I glance down at the phone, data will be syncing.
Hi guys I got a big problem, hope u can help.
I have this phone for a couple month already, when I was still running stock I discovered my cell phone would tell me I got no signal. Turning on air plane mode and then turning it off didn't help to get back signal. So I had to turn off the phone and turn it back on to get back my signal. Problem is I never know when it happens until my wife asks me y my cell phone is switched off. So I went ahead rooting it and I flashed a rom on it. But problem isn't gone. I still lose signal but on this rom it shows me full bars, only cannot make phone calls,SMS,and gprs. Tells me no network or no sim card is inserted. I always have to turn off and turn it back on. Now that it is rooted with whatever firmware I can't bring it to Samsung store to fix
please any suggestions?

Sounds more like a carrier problem. I'd ring them. Check your APN settings too.
Hi,
I have similar issues. Doesn't matter where I am and how good the network coverage is on all other phones around, my SGS2 keeps changing the coverage icon, from 1 to 4 "sticks" of indicator, or to no coverage state (crossed circle icon).
Sometimes the wireless is not working also, or juts gets very weak signal, though the signal is good on other devices near by.
When I try to turn data network (by pressing the power button and selecting data network activated from the pop up) sometimes it's not even showing the data network icon in the system bar (top of the screen), it's like being disabled data network or something.
I can answer a call and stay on conversation for no longer than a minute, then the signal goes dead and the phone just freezes, when I try to tap red button to end the call - no reaction, I have to turn the phone off.
When I try to make a call it just says "dialling" for ages with no result and eventually the phone freezes, so I have to turn it off and back on again.
Sometimes it turns off itself though the battery was showing almost full icon.
I went to O2 store, they gave me new SIM card, but it didn't help, so it's not a SIM issue.
I did a full (hard) reset - no help.
The guy from the O2 store told me, that I can root my phone, and I will not loose the warranty (I purchased the phone only one month ago), only thing I need to do is to revert it back to original state before bringing it (in case of hardware replacement).
But if it is not a software issue at all, so what's the point of rooting and having all the hustle, then reverting, etc... Can there be some hardware issues? I don't know: antenna, RAM, CPU, whatever???
I hope I've explained everything clearly enough. Any ideas would be appreciated. Thanks in advance.
What firmware are you on have you tried to Upgrade via KIES .
Rooting will void warranty and will also increase the custom rom counter from zero . Yes they can be reset in most cases .
Rooting will not fix anything at all .
Network is first check are you getting problems at all locations .
When in the O2 store did they check the signal ???
Choice return to service centre
Flash a stock Samsung firmware via XDA possible to also try a different modem via XDA .
None of these will fix hardware problem .
Personally i would factory reset the phone and check all the network details are correct on the phone then return to service .

when you have this problem check if you have an imei (*#06#) if the response is empty then you have to reflash...
Hi all again,
after posting my previous post I phoned my friend during a lunch break at work. We had a quite long conversation and the quality was perfect. Then on my way home I turned on data network and enabled GPS (LOL), then launched navigation app and it took me home without any bugs (I know my way home though I did it only for phone testing).
Now back home, sitting in my room and my SGS2 starts to fool around again: unable to turn on data network, poor wireless signal (but it's good on my PC), the network coverage icon turns into "no signal" state and comes back to normal again all by itself.
I will definitely test my phone again tomorrow on my way to work and in the office. But it seems like there's something wrong with the place that I live. I've moved in recently and must admit, that all my problems with the phone started only then. And I didn't noticed any bugs while at work or anywhere down town.
Meanwhile is there any way to scan/check the area around my flat? Maybe there's something wrong with the in house router, or maybe to many routers in surrounding flats, or some other equipment/hardware things messing up, or just a mysterious house blocking O2 network and hacking the phone LOL??
The only strange thing is that I'm having not just a network/coverage/wireless issues, but the phone freezes, battery full-empty-full-empty status randomly, etc...
BTW, my details:
Model: GT-I9100 (not a I9100G)
PDA: XWKJ1
PHONE: XXKI4
CSC: O2UKJ1
Android version: 2.3.5
Updated via KIES about a month ago, was working good until now. KIES says that at the moment I have the latest firmware.

let me list the modems ive tried so far
xxki4, nefk2,xxki3,nekd5,xxki1,xxke7,xxkg3(on this one right now since morning),xxkh3 and xxkl1
6 more modems on the list havent tried, wish me GL
So I changed modems to the T-Mobile.one or whatever to try it for the heck.of it cause I have a backup prepaid that roams on T-Mobile 3g and of course it worked. But anyways I had horrible service with my att. Sim with just edge. So I put the stock att. Modem back on. Well when installing it in cwm it says T-Mobile something while installing. But when I check status it shows ucla1 or whatever. But it seems like my service kinda sucks than what it did. Anyone experience this? Didn't really wanna reset the phone

Hey,
I was playing around with a few Custom ROMS today, and my mobile data stopped working. The APN settings are correct. I have flashed multiple ROMS but no luck. Even stock ICS ROM. I think I have the wrong modem/baseband combination.
My phone show H+ or 3G icon, but as soon as I try to use the internet, it vanishes. Wifi works fine.
Any ideas?
Seems like incorrect apn.. but you already say it's correct..
Try to Flash the stock modem..

Yes the APN is correct.
Could someone possibly tell me which firmware I should flash? I purchased my phone from Pakistan, but I'm not sure which region it is for. Will that make a difference?
Something happening with this phone. I had the same issue a few weeks later.
I tryed almost every modem available unsuccessful. Just my local carier can solve. I didn't known what they did, but solved until now.
Although your apn settings may be correct, they may need updating.
This sometimes happes in the uk.
Maybe if you tried deleting the apn settings out and then ringing your carrier network up, and asking them to sent your correct apn settings to your phone, maybe this could help.
Its not a dead cerainty but always got to be worth a shot mate

Had the same issue with my GS3 (I9300) after switching from those Straight Talk Bastards to AT&T:
Whereas Straight Talk simply f*cked up b/c of a collapse of their data network, so I assume (with nobody at ST saying a word for 2 days, of course.. ), it turned out that AT&T actually had deleted my new account - by mistake - after just one week of 'happy browsing'.
A trip to the local AT&T store solved the mystery and got me up & running again.
Unfortunately, though, it took the AT&T folks a while to figure it out, as they are not used to unbranded/international/ unlocked phones wanting to join their US network. (Don't even try to solve this over the phone, if you have a choice).
Kudos to the AT&T staff, though, as they got the problem resolved eventually. It definitely helped a great deal that my phone had been working just fine on their network just a week ago, so I was able to stand my ground and insist that the problem was at their end.
One of the reps - apparently without a clue - tried to tell me all sorts of BS, e.g. that the I9300 would not work on AT&T; that some Samsung phones supposedly don't work with their network... bla bla blub blub...
Fortunately, I knew better and told him so. Otherwise, he may have successfully gotten rid of me; making me search for the problem someplace else (a.k.a. giving me the run-around or making me chase my tail, etc. :banghead: )
Thanks to xda (and the Internet), however, I had all the knowledge necessary to make sure they get it back to work. Now I'm browsing the web again with 7Mbps Down/3Mbps Up speeds, using AT&T's really fast HSPA+ network here in the Chicago Northern Suburbs (close to O'Hare)... Yay!
Good Luck with finding the problem with your data loss issue!! :thumbup:
P.S.: Let me know if you need my APN settings; just for comparison (.. in case you are in the US, too).
Cheers,
AA

hi. I have a samsung galaxy s2 i9100 (for now 3 and half years)

for some time i have been experiencing loss of network all of a sudden thoughout the day
specially if i tether my phone via wireless
i have changed its software (rom and modem) and I am still experiencing this loss of network
in order to get network again I must reboot the phone, it is the only way of getting it back working
I travel a lot to Portugal and take the phone but I do not seem to have experienced this there
tough i dont tether there nor i use the connection for data
currently i am using a slim rom 4.2.2 build 8 official
the baseband is i9100xxLs9
any toughts about what is happening? do you think the phone is to blame? software? hardware? sim card?
Modem is what the culprit.
Change to other modem and see

Hi! Thanks for the reply!
I already tried that. I reflashed and put a new modem aswell.
It improved the simptoms but they still persist
Any specific modem that you think i should try?
Some times my phone freaks out and just gets corrupt and i have to reflash
Do you think it might be going to die? Maybe replace it?
Best regards

Put it on gsm mode which is also called 2g mode.
Monitor it if you still loose signal.
If so, then i would recommend you do a clean wipe, use any rom wipe script available and then install your rom back
