Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

It would be interesting to know your SGS2 is white version as well as mine.
I have to say that I have another SGS2 but old black version which is perfectly functional on the same 3 network. After playing a very long times with both phones settings, I have a feeling that the core of the problem lies in the "APN type" setting. Changing it's content affects how it connects to network. I have no deep understanding of what is happening behind the scene while changing this option, but there is a possibility that the portion of file system responsible for it somehow been damaged.
It would be great if the developers could tell us if this part of the Android file system is changed while flashing different firmware/radio, or it is persistent?

Dial *#*#4636#*#*, go to phone information and see the settings for the radio. It should be at the bottom. Google the settings for the GSM, WCDMA. Mine is currently 'GSM auto PRL'. 'WCDMA Preferred'is also a better option for 3G network.

Thank you. I fiddled with GSM, WCDMA settings as you said, but no luck.
What is even more interesting is if the network mode is set to "WCDMA only", then I'm not even able to register on 3 network. After an attempt to manually connect to 3 via "Network Operators" menu, it says "Unable to connect. Try later".
Also after connecting via WCDMA, and then reverting back to GSM, the GSM dies as well. The only solution is to restart the phone.
If it is a software bug, then I do not understand why this problem did not go away after flashing different Rom with radio.

exactly the same for me also, by the way i've a black version
Same problem
Same problem for me in Spain...
WTF happens with this Galaxy S2.First USB voltage problem and now no 3G/HSPA connection.
Any solution, plz??
Samsung: never again
guys....carriers can't sell a device that is advertised as a 3g capable phone. Call them and spit "misleading advertising" mixing "give me a phone that I can actually use" words. You could also add "Release me from my contract, I'm moving to other 3g WORKING carrier".
They'll just freak out.

Back to Business, are you completely sure of this? I am having the same problems, no 3g anywhere I've tired 7 different ROMs 3 different kernels, every setting I could find I've toggled and no luck what so ever, I'm on a T-Mobile no contract plan and I have the black I have the international unlocked version

T-Mobile USA?
If yes, you're probably in a market that they have not yet re-farmed the 1900mhz frequency for HSPA+ yet. The i9100 doesn't get 1700mhz, and the majority of T-Mobile USA's network uses the AWS band, which requires both 1700 and 2100mhz to work for 3g/"4g".

Hi there,
Since a few days, I've got a serious problem with my SGS2, it randomly loss any networks, saying that the flight mode is on. I tried to flash with another firmware ( stock KE7) it change nothing.
Any idea?
This is a firmware issue with the modem. Mine did the same thing. KE7 modem is horrible. I flashed to KF2 modem and I don't have this problem anymore.

i believe this is related to the network itself. for my 2 other phones before, whenever i am AUTO network Mode, many callers used to call me reporting 'My mobile was off'... also with S2 the same issue.
i switched to GSM mode only, LOSING my NETWORK Data SPEED, for this ..
i hope future firmware can solve this with as suggested above, Good RADIOS....
The problem is that i've already tested with another provider's simcard and i've got the same issue. I tried with some firmware (stock KE2, KE7, KF1, Litening 1.4) but it change nothing. I'm from france with 'Virgin" provider if this can help.

I'm on Orange UK and that happens to me quite often. It's something to do with the network and how it handles the switch from gsm to udma(I think, anyway). Sometimes the network doesn't fully recognize you've switched from one type to the other and reports your phone to be offline. It doesn't usually last long but if someone tries to call me during that time then I'll get a text message when the network catches up to tell me I've missed a call.

I don't think the problem can be fixed on the user end. I had the same issues with a Nokia N80 and N97 mini before I switched to the SGS2. It's apparently a common problem that all networks sometimes have and the only way it'll ever really be fixed is if the networks improve how they handle the switch.
I think it also depends on where you live. If you get a constantly good 3G/H signal then in theory the phone should hardly ever need to switch to GSM mode, but if you live in an area where the signal is not so strong then it might switch more often which will cause the problem to be more severe.
You could of course try setting the phone to WCDMA only which will give you good speeds, but then if you drop out of 3G range you'll lose the ability to make & receive calls anyway. It unfortunately seems like a lose/lose situation.
As for the flight mode issue, I really have no clue what is causing that. Have you tried hard resetting and/or flashing new firmware?

Change your phone..
I had the same problem on my first SGS2..everytime when gsm/wcdma auto is selected..phone randomly looses internet connection and radio switches off. In gsm only mode..everything is fine. Got my second SGS2 and phone is perfect..no loss of data connection even in the worst coverage area..
You can read "serious issue on 3g" thread in the general forum and see if you are suffering same symptoms

@Iznee
i dont think changing the phone might be the issue, i had the same issue on IP4... it might be solved with future radios/ roms...
So I have a Note 2 and a HTC one, for about three weeks I used my HTC one and then i switched back to my note 2. Yesterday I wanted to use my HTC one but every time I insert the sim card I get a no service message. what can I do to fix this?
I did not root the phone BTW.
Have you found a resolution? I just ran into the same problem. Phone was working great, then one Sunday afternoon it just stopped getting a signal. It's not the SIM as it works fine in my old SGSII (had to make SIM adapter). I am rooted and unlocked and running non stock recovery but still on stock kernel/radio. Haven't contacted HTC yet for obvious reasons.
I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.
A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically
If that doesn't work then try settings/mobile data/access point names/menu/reset to default
Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing
I have a bit different problem - I bought HTC One from T-mobile and unlocked it. I tooked it with me to Europe and device does work with american sim (ATT and TMO) but it wont recognize any of my national carriers. Insterting simcards(perfectly working) does not give me reception or anything. Sim cards are the same thing in EU and US I think - also those are GSM phones. I have friends having same problems with their S4 from AT&T in Europe. Does anybody know something to help make this device work?
OP - this happened to my Wife's phone for no apparent reason one day. I simply removed & reinserted the SIM and rebooted a couple of times, hasn't had a problem since.

I changed my SIM for a new one. Seems like a new SIM cards are a bit different from the old ones because after I did that I had no problems

Same problem here. I am on paranoid android though so maybe that has something to do with it. When I go into the settings to connect to the t mobile network, it says "your sim card is not authorized" or something like that. Maybe it's cuz I haven't paid my bill for 2 months? Lol but I don't think that's reason for them to block my sim :/

I had the same problem and I had to restart my phone sometimes several times a day, sometimes I had to remove the sim card enclosure and reinsert it in order for my phone to get a signal. So I contacted HTC and they told me that I probably had a defective sim card enclosure so they sent me a new one. After I installed the new sim card enclosure with the same sim card I had before the problem went away. I've been without any problems for the past four months or so since I got the replacement sim enclosure
type *#*#4636#*#* -> phone information -> make sure GSM/WCDMA/LTE Auto selected and Turn off radio
If you see turn on radio click that to turn on the radio. Is some cases the radio gets turned off and a reboot doesnt fix. This is the only way I know to recover it.
I've this same issue!
Did anybody found a solution?? I already tried everything... but seems like the phone is not blacklisted.. in case it is, something I can do? besides change my IMEI.
Thanks!!

I wonder if anyone can help please. My M7 can't connect to the network. The radio isn't turned off, I checked using the code given by Shane_pcs, so I know it is a hardware problem. I suspect the radio chip has worked loose somehow and isn't making contact like it should. Any tips on how to resolve this please? I have seen a tear down of the M7, but don't know if anyone on here has attempted to secure the radio chip before...not even sure what the chip itself looks like. Any ideas please? Thank you.

How about ask your local service person for the correct settings, or hopefully someone on this board who lives in your area can post theirs.
Is there an OTA specific to your phone?
While not the case with you currently, it may be important if you travel--there are some areas where certain carriers don't have that coverage:

Aircel uses 900 and in some places possibly 1800. Do you have a data plan? Have you spoken with a support person with any one of your carriers--they're used to things like this and getting in the proper settings. I would strongly recommend that.
Check the Settings->About Phone to find out which version of android you have, and if you are running a custom ROM or not.
Do all of that first--make sure you have a data plan, speak with a support person, find out a little about your phone.
If you are stock check with your support person if there is an upgrade for you, also.
If you are NOT stock, you might want to go back to the Stock GB or ICS (remember to update the radio also) so your phone will be basic and stable, to be sure it will work at all with data. Once you've determined if it will work with data, then you can try one of the custom ROMs if you like, but NOT JellyBean or KitKat, as they are all problematic.

I have a data plan activated...I have not done any change in software...the current version is 4.0.3..and aircel network is not at all working on my device..that y using Idea network (that too working only in 2g mode)...I cannot have support on the device as I purchased it online from someone else...and it is not a device which is for India... it is a T-mobile device..Do you this change of ROM will resolve this or will it still remain the same... can there be a problem with the antenna (but 2g network is working fine)....

I have a data plan activated...I have not done any change in software...the current version is 4.0.3..and aircel network is not at all working on my device..that y using Idea network (that too working only in 2g mode)...I cannot have support on the device as I purchased it online from someone else...and it is not a device which is for India... it is a T-mobile device..Do you this change of ROM will resolve this or will it still remain the same... can there be a problem with the antenna (but 2g network is working fine)....

I think it should still work. The tech should be able to give you settings regardless of the device origin--you're still paying for a plan, and some support should come with that.
Nevertheless, check this to make sure you have the right settings.
You "may" also have to call T-mobile and ask for unlock code for your phone--they will ask you for the IMEI.
I don't know if necessary, but have read something to that effect--that in using the Amaze 4G in another country, you need to have the phone unlocked. I'm sure someone else on the boards here will let us know.
The back cover houses the antenna, and yes, it could be the antenna, but unless you have another back cover to test it with, it will be best for you to check the settings first, and then see if it needs to be unlocked.
Then come back here with what you've learned--it'll help me learn too.
The ad said that the phone is unlocked... I purchased it from Ebay and I have a prepaid connection with the provider.. it is "pay as you go plan" so I guess they wont provide much help as I have seen customer care people putting their hands up many times saying it is a problem with the device and they cannot help...that's y I was trying to get some help here on the forum as someone else could also have faced the same issue and can help me with their experience...

Besides the firmware update, there has been a separate radio update.
I think these are the most recent updates:
Software number is 2.14.531.30 710RD
Baseband version is 1.15.550L.08DC_30.80.550L16D
It's possible that your phone will work with them.
Does anyone else agree?

You may be able to just put the official OTA on your exernal SD card and flash through recovery--not quite sure yet.
I gotta see some of the settings info, so for starters go into your settings->about phone, screenshot the page that appears and also scroll down to any new pages, and post screenshots here.
How to screenshot:
http://forum.xda-developers.com/showthread.php?t=1885386
After that, reboot the phone into recovery following these instructions, and screenshot the recovery screen and post it here also:
Power the phone off and wait about 10 seconds after the screen goes black to be sure it's off->hold Volume Down button, while doing so press the Power button, and release both buttons.
The phone will boot to bootloader, should say hboot up top, and have a little list below it.
If you can't screenshot it via the previous method, note if at the top of the page is says Locked or Unlocked, and if it says "S-Off" or "S-On", and note the version of hboot so you can post the info here.
Use the power down button to highlight the list item "Recovery", and then press and release the Power button to enter the recovery. After recovery loads, note if it returns to a screen just like the hboot screen, or if says in it "TWRP", "CWM", or "4EXT" or any such other thing, and screenshot that or get the info and post that here also.
Now that you've learned what sort of state the phone's in, you can reboot from whichever screen you're on, and have your phone back to normal.
Once you're back with your phone booted, you'll find a screenshots folder in gallery most likely, else you'll have to search the phone with a file manager app or google to find it, but check the gallery first.
After that we'll look for the proper update and update method for you.
Hopefully by then someone else will come along and say something like "All he needs to do is download this "Official OTA" [link included] and put it on the SD card and flash it via hboot"--hopefully, 'cause I may be making this more complicated than it needs to be.
Here, let me repeat that, "Hopefully by then someone else will come along and say something like "All he needs to do is download this "Official OTA" [link included] and put it on the SD card and flash it via hboot"--hopefully, 'cause I may be making this more complicated than it needs to be."
In bootloader, it is showing as:

HBOOT-1.93.0003
OpenADSP-v02.6.0.226.00.0202
IN RECOVERY: Team Win Recovery Project v2.3.3.0
I have also added screenshots as attachments for the about phone setting menus.

You did a good job with that--thanks. Hey, you're in good shape--everything is new enough.
You need to Super CID your phone, and then flash a rom for one of your local (in India) carriers.
Super CID instructions:
http://unlimited.io/juopunutbear.htm
ROM for carriers:
Sorry I can't provide the link--I'm having a helluva tough time searching.
Maybe by the time you've Super Cid'ed your phone, someone else will tell us where to find a proper ICS RUU for India.
Thank you
Thank you for taking out time for helping me...can any other rom (other than the T-mobile) working... and I dont know what is RUU..lol.. I am pretty new to these terms.:laugh:

In order to use the phone in your country you need to have one of your carrier's firmware on the phone so it is compatible.
You can't put their firmware on your phone until after you've performed "Super CID". After performing that, other carrier's firmware can be flashed to the phone.
RUU restores the phone to factory condition. Let's not concern ourselves with that just yet--follow the instructions to Super CID.
Hello All,
I am hoping that someone can help me out.
I purchased 6 Samsung Galaxy S3 unlocked phones. I put SIM chips in each, all from the same provider and all with the same service plan. 3 of the phones everything is working great including fast Internet. The other 3 phones have extremely slow Internet. I did a bit of research and noticed that the phones that are slow display EDGE in Mobile network type. The phones that are fast display HSDPA:9 . Could this difference be the cause of the data speed problem? Can anything be done to fix it?
My apologizes if this is being posted in the wrong forum.
Thanks

In your way, EDGE means slow, HSDPA fast, HSDPA offers speeds up to 21mbps (if your carrier supports it) and EDGE up to 0.5 mbps or so.
Now, if your 3 other phones don't connect to HSDPA (3G) then it's disabled in settings or signal is low or the chip is messed up.
So by checking if everything is good go to settings, under first tab (connections) go to More networks > Mobile networks and make sure that under network mode WCDMA/GSM is checked, notice that WCDMA is HSDPA.
If still not getting faster speeds try to check if WCDMA only option works, if not, eh, bad chip.

Thanks for the reply.
I activated the WCDMA/GSM. As soon as I did the icon status(?)displayed on the top of the phone turned to a circle with a line through it. About 3 minutes later the status changed to an E with bars next to it. The Status/Mobile network type still says EDGE.
When I try to connect to a site it is slow. Does this mean the device is still getting the 2G signal? Could all 3 phones have a bad chip?
Thanks.
that is true

Do all of the phones have the same baseband? Check in settings, about.
Just to make sure the modem is the same.
I just check 2 of the phones (they are all not with me now)
The baseband of one of the good (fast) ones is: I747UCDMG2
and on one of the slow data phones is: I747MVLUEMK5
What does this mean, that they are not the same?

Both are i747 version which is not international version, maybe Korean or something like that, try using only WCDMA this is constant 3G, and see if it works, if not, flash the latest software from sam mobile via Odin, but watch out you download for i747, not i9300 etc. There are many S3 variants.
I tried using only WCDMA with no success.
Do you have instructions of how to locate and flash the latest software? Also I know the phone is currently unlocked would this change that?
Thanks so much.

If it is unlocked, it shouldn't change that.
And note if changing software doesn't help then the chip might be damaged.
For software, go to www.sammobile.com and register, then go to browse firmware and select android/galaxy s3 bla bla.. until you get to country, there select your country, or go to top and select 'top 10 latest' and choose one that is different from yours.
You can know of it is different by the baseband name letters for etc 'XXUGNG3'.
Then download the software you want (it may take a while) and download Odin v3.09 (just type that in google you'll fond ot) and Samsung USB Drivers (also found on google easily).
Install usb drivers, reboot, open Odin, extract downloaded firmware, go to odin and select AP and then navigate to extracted zip and select you software.
Then put your phone in download mode: hold vol down+power+home and then vol up for continue when you see the picture, connect your phone and flash.
Also, please, about that, read here on xda and see tutorials on youtube, this has been answered multiple time and.i am one of rare users that will thoroughly help in answered questions.
I followed the instructions and flashed the phone. It did not help.
Any other ideas? One of the phones we got was brand new! I can't imagine there is a faulty chip in 3 out of 6 phones?
I am frustrated.

Are they unlocked? Of they are try another carrier, or try somewhere where the signal is at it's best reception.
If these simple methods don't work just get it analyzed in the service center, i doubt it can be software problem because you tried with another rom, also, when you'll try maybe changing carrier or going around town to see if it works, and it doesn't, then it is hardware problem, unfortunately.
Thank for all your help.
Nothing seemed to work.
I did try another carrier and it did not work.
I just can't imagine that 3 out of 6 phones have the same problem and 1 of them is new.
Could it be that the 3/4 G only works in the USA and not in foreign countries?
I bought the handset in UK and everything works fine except I cannot get the mobile data to work. I have a good reception, the handset shows 3G but no arrows to the side of it. I have changed the APN settings to my network (Talkmobile), switched on mobile data etc. but still no mobile data, please help.
when my phone dropped to 3g the internet didn't work either here in Ireland on 3 mobile.
4g would rarely stick, just putting the phone in my pocket sent it back to 3g.
this is most likely a hardware problem not software.

Thanks, but I've never got mobile data to work at all, the APN settings are all correct and the 3G symbol appears on the screen, just no arrows next to it.
A fair few people are having the same problem, myself included.
It works better if you switch to 3g only, but sometimes that doesn't help either.
Let's all hope elephone get there act together on this, it's all very well having a great screen, CPU etc, but with no network data (& sometimes calls) it counts for nothing.

Thanks for this. In the APN settings I just changed the APN type from 'net' and 'MMS' to 'default' and this worked.
It's weird, is there some sort of learning process with this phone & network settings?
When I first got the phone it was rubbish, but as i used it more & more it got better. But then I rooted it & did a factory reset & same again. This morning I put the darksense rom on & it was still rubbish. But as the day's gone on its got a lot better - 4g & everything is working fine.
But thanks, I'll bear the APN change in mind
There are lots of APN settings to edit, I don't want to mess with what I don't know, although sometimes that's the only way. Does anyone have knowledge in this department?

This code just gives me info, can't change anything.
Do you mean *#*#3646633#*#*?
& then where to select usa?
Have a try at this:
Settings>data usage>mobile networks>network operators (will search, might take a minute)>select your operator in the list, in my case 3(4g).
For me it's been solid since, 4g a lot too.
oddly enough changing the band to USA is keeping the phone on 4g for me yet im in Ireland on 3 mobile.
had it set to Europe or Automatic before that.
lets see does it stand the test of time.

I'm definitely beginning to think this whole issue is a wrong network setting, what I did worked for me (solid all day) - post #10, & I've seen a few do this & it's worked too
after a full day it definitely fixed the issue, 4g signal is strong
cant believe they mixed up something like this.
the average novice wont have a clue what to do.
i was on the brink of flogging the phone.

Update major issue if you change the band to USA via *#*#4636#*#*.
The 4g data will work great but you can't receive or make calls unless you change it back to Europe.
How do i change the band?

Press the three dots top right at phone information
(*#*#4636#*#* -> phone information)
As far as I know Talkmobile doesn't have 4G they only offer 3G for now so no matter what you do with the APN you'll never get 4G, also with most MVNO services you will alway need to setup the APN manualy as they use someones elses network in the case of Talkmobile they use Vodafone.
