hello again forum ! today i want to ask help with data connection and probably modem issues Or say that the sgs2 has connectivity issues in germany, and which modem are appropriate for this region.. currently im using KI3 modem and revolutionROM, my intetnet connection (with speedtest) is 24 kb/s with edge connection only. It rarely goes down to G, and very very rarely jumps to 3G and H+ but in ten seconds or so it goes back to edge or even to grps..
so the phone is 2.3.5 with revolution rom (i installed it today ! i was having issues before too !), a KI3 modem (i tried a lot of modems and i think this is the best one for now, but im not entierly sure). So my location is Germany, and my operator is Mobilka (E-Plus). The main thing im aiming is to get something higher as E.. 3G or even H+
As a comparison and proof, my friend has an HTC magic 32B vodafone branded, has Aldi Talk as his phone carrier (that is E-Plus too, so i think its the same) and he is having a constant 3G connection !
Hoping on finding some help here, thankyou c:
bump. anyone ?
sigh, i guess this can be rephrased as a question.. could any of the mods move the thread to the Q&A forum please ?

Hi,
I have an O2 XDA Exec with the latest ROM version, on an Orange Pay Monthly SIM.
Anyway, im having two annoying problems with it;
Firstly, every now and then, if you have a few programs open and close them all, it wont go back to the Today page!! It will just keep the image of the last application on the screen! Today wont even come up if you goto Start > Today. Everything else works fine though, can open any programs etc from the Start Menu :?:
Secondly, the phone signal is rubbish!!! My old SPV C600 had no problems with signal (also running WM5), this one has low signal/looses signal all the time! And after a while it will just stop searching for signal, so i have to go to settings and tell it to search again!!! I constatly have errors trying to send messages due to no signal, and cant make calls due to no signal!! Also i dont recieve texts alot aswell! Which is un-acceptable from a device that is meant to be a "mobile phone" :roll:
Any ideas to solve?! Please help me!!
Thanks

Hey Matt
what are your ROM versions? especially interesting in this case would be the Radio version. I think people round here have mentioned that different Radio versions have different signal reception levels.
I am using the O2 XDA 1.30 version with stock radio 1.00.09 and basically the reception's fine. There have been some comparisons on this forum as to different radio versions strengths and weaknesses.
Hi very similar to me, I switched off the 3G usage so it only uses 2G and everything was perfect again.
Now I only use 3G as and when I need it.
The problem as I see it, is that if there is a 3G signal, which in Orange's case appears to be nearly all the time the phone sticks with 3G even thought the signal strength isnt good enough fo voice, but is good enough for data (mainly because you tend not to be walking around) because of this the switching between 2G and 3G doesnt take place, hence no calls
Since swtiching of 3G my phone operations have been perfect.
I switched my Radio ROM from 1.03 (Orange Default) to 1.09 and noticed an improvement. Where I had no signal, it would flick between a signal with no bars and 1 bar with the 1.09 ROM.
I switched my Radio ROM from 1.03 (Orange Default) to 1.09 and noticed an improvement. Where I had no signal, it would flick between a signal with no bars and 1 bar with the 1.09 ROM.
As soon as i got the XDA i upgraded it to the latest O2 Rom, which has 1.09 Radio Rom... so i dont have anything to compare to!!
Any more suggestions?
turn off 3G if you dont need it.
send it back, you may have a loose connection.
are you saying a bad connection 100% of the time? ie you never have full bars?
Ok i'll try turning the 3G off (seeing as my SIM doesnt have 3G capability anyway! lol) How do i go about doing that?!
I do get full signal in places yes, its just the signal is utter crap on this phone compared to all of my past ones! Compared to an SPV C500 & C600 its rubbish!
start - settings - phone - band
change to your standard not auto. probably gsm rather than cdma.
do you get a bad reception with4 bars?
either way, I must say I have no problem with phone, but acknowledge many report poor phone performance.
Hi All, I have been reading the forum with great interest and trying to amass information so hopefully I can avoid sounding like a numpty when I ask a question, here goes;
I have an X1 on O2 UK and an unlocked Touch HD and both seem to have the same difficulty sustaining an EDGE data connection.
At work for example the phone is showing 2 bars of EDGE, as soon as I start using the phone even if its not data related the data symbol changes to G so assumedly my data speed drops, I dont know because I've never got the phone to sustain EDGE long enough to see if its any faster.
Can this be fixed with a particular ROM or does no one else experience it? Network is O2 UK.
Also I read on another thread you can only change your radio on a Pre-release X1i, is this true and what does it mean exactly? sorry, probably a newbie question.
Changing your radio means updating the Radio ROM version that looks after GSM, Bluetooth, wifi and FM... basically anything received or transmitted by radio. If you go use one of the official SE update ROMS from this thread...
http://forum.xda-developers.com/forumdisplay.php?f=471
... then your Radio ROM will be updated along with all the other ROM and OS files on your phone.
I have a similar problem with O2 and my X1. I may be lucky to get a H (HSDPA connection) for a couple of seconds, but the phone drops and attempts to reconnect the phone completely, GSM, GPRS and 3G. It also has trouble staying locked onto O2. I have a dual SIM adapter and my Orange SIM can go a whole day without dropping while the O2 one will drop 4-5 times a day.
I'm tempted to call up O2 and request a new SIM as my O2 SIM is getting quite old (about 5 years now). I'm wondering if these new specifications require updated SIMs.
Don't believe everything the bars/icon says! My X1i shows EDGE, but when surfing changes to 3G or sometimes H for a few seconds while actually downloading stuff. The H doesn't stay on to save battery, but everythings fast. (download something to test the speed, e.g. SPB Wireless shows 760kbit/s)
Hi,
I'm currently doing my community service at a place where the network coverage is very bad and I often get the failure message "Data network not available." if I want to call someone. Sending messages does also not work and other people also can't call me.
To solve this I always have to disable the data connection and restart the phone once or twice.
The failiure message doesn't occure if I disable data connection and set the mobile network to GPRS-only.
I had the same issue with different modems and roms, these are:
JPY, JS5 and JS7 testet with the JPY AND JVE modem.
I can't tell you if this also happens with CM7 or JV1 because I haven't used them at work long enough.
I know that there have been a few threads about this, but there aren't any solutions for this problem, so maybe you have I magic trick for me or we can solve this together?
Btw: I have the international SGS (GT-i9000) and I'm currently running JS7-Rom with JVE-Modem and supercurio-kernel for ext4-filesystem and root access.
nice regards
mike
Ps.: Except for this issue, the phone is really great. I have it for two weeks and I like especially the samoled display .
Looks like your area doesn't have proper 3G Network.
I think we all get this, I know i do. What it really seems to mean is, you have no network coverage from your main provider (calls/text and data), but if you need to make an emergency call I have found another network I can use.
But i have a working normal GSM connection, only 3G/HSDPA is not available everywhere. And I should at least be able to make phone calls if I have GSM connection. (Sendig SMS should be available too of course.)
My old Nokia 5800 with Symbian worked everywhere without any problems.
thank you
nice regards
mike
Does the phone work correctly well away from that location .
jje
check your APN entries make sure they are correct
Hi,
yes it works when I have a better network coverage without any issues .
APN-Entries are the right ones.
What I should tell you is that the 3G network coverage at the place where I work is really extremly bad. Sometimes when you walk a few meters you have a working 3G connection and sometimes not and because I only have to work there until the end of June it's not a big deal but I thought I post it here because it might be a bug in the modem.
nice regards

....you just answered your own question. Just use gsm/edge/2g.
Sent from my GT-I9000 using XDA Premium App
But why does the calling app use the 3G-Connection if GSM is enough?
Better quality?
thanks
Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.
Things I have tried -
Turning off fast dormacy
Editing the build.prop http://forum.xda-developers.com/showthread.php?t=1097612&highlight=build.prop pages 1-5
Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.

That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .
jje
I will have to give this a try and see how it works, thanks for the share.
I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!
would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well
Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .
jje
Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.
Just been out and about and tried that setting, didn't make much difference unfortunately
Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

The wife is on Giffgaff so I think I'll give that sim a try before I get my PAC off O2.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio
confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio
Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!
I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.
Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.

Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?

Helo all..
I just brought that phone s4 9505 lte version for 1week ago. And at that time I did not find any issues on my phone. As u know I only checked using wifi and play games. It seems to work well everything. But today I am realized that something wrong in my galaxy s4 particularly when I use data network. The main problem is in the H symbol that always appear in the top of the screen with 2 sides arrow. When I do nothing with my phone or idle for a short while, the data connection suddenly stop working which means u can not browsing at all even making a call and texting. So the only way is to refresh the network or change the mode or restart your phone.
I dont know why it always happen in my phone many times. I have tried to refresh network and change the mode then give back to the wcdma mode. It occurs same issues again after a couple hours. But I did not notice where I use gsm mode.
About my signal is good. No drop signal at all. But I always encounter that problem. Maybe anyone who has the same issue .. plz inform then we can try searching out the solution. Thx
Addition information.. I buy this phone from singapore comes with official local warranty.
Actually. I have not tried to change another provider and I hope this cell is not fault factory.
I will try with different area and provider first then decide possibility

Are you on vodafone? There is quite some discussion going on in german forums where the lte - 3g change seems to be problematic when on vodafone network with the i9505. If so you might want to check forums like android-hilfe.de or so. Btw. Im in switzerland on provider swisscom and have the same problems. Data connections drops completely every few minutes. Very annoing.

Yes I notice in other sub thread there are quite a lots number signal problematic. Yet in my case is different from that case..
I just tested set into wcdma mode along night and until now it still work perfectly. This problem can not be predicted when it will occur. Sometimes I browse internet for 2 hours..afterwards my phone can not be used completely even testing and calling. I hope this is a provider caused.
