[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP

did you install DroidWall ?

Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?

Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.
Anup

Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

The problem is that I'm not from Czech Republic. The phone was purchased there by a friend of mine and brought to me...

[Q]Odd signal issue

Ok, so I know it's not the csc, or the rom, or the apn settings, or the modem, or the band selection. It's not an app, or even a signal issue. It's not the service or network selection. Wiping didn't help nor did a factory reset. Every time my phone connects to an edge network, it won't connect to an hsdpa network without me going into settings, wireless and network, mobile networks, wcdma only and then back to gsm and wcdma. Any suggestions?

Anyone that comes up with a half-way decent suggestion gets a Thank You....
I'm guessing that no one has come across this before? It's not like it won't connect to HSDPA, it's just that it won't connect automatically. Believe me when I say, I've searched samsunggalaxysforum, google, and xda for a solution so I don't think this is a problem that has been posted here as of yet. Forgive me if it is and lead me to it....

Bump.
I don't think enough people have seen it before it slips into the nether regions of the forum.

I changed HSDPA revision to option 2 in band selection (HSDPA/no HSUPA). It worked off of airplane mode, which it hadn't done before but the same issue persists. When I get to work (where there is a clear HSDPA signal) from home (also clear HSDPA) it's on EDGE. During travel or when the HSDPA signal is not available, it'll just stay on that **** EDGE network even when I get to an HSDPA area.

Same problem on a clean stock rom ???
jje

Come to think of it, I'm not sure. HSDPA is new where I live but not where I work. I did, however, do a repartition in Odin of the JS3 firmware and then a wipe with Darky's 9.2 and 9.3. Of course I didn't really stick with JS3 for very long before flashing to Darky's ROM but this isn't a problem inherent in the ROM itself or others would have reported it. Furthermore, I've switched between kernels, file systems and modems and yet the problem persists. I haven't enabled any tweaks with any kernel I've used either so that shouldn't be an issue, should it?

Maybe try this.
Dial *#*#4636#*#* ->
Go to Phone Information -> and perhaps play with the Preferred network type?
If noen of your efforts have resulted in anything meaningful, the suspicion goes to your operator.
Hope this helps.

i have the exact same issue although 3G is available in my area when it once logs into edge mode it doesnt wanna change it. only when i restart the phone it logs onto 3G again.
pretty annoying
maik

You can go into wireless and settings, network settings, wcdma only, and then back to wcdma and gsm and it'll connect to 3g or H. At least that way you don't have to restart the phone every time it does it. The main thing is finding out what can fix the issue.
For some reason, the phone information settings don't stick. I've tried to use wcdma preferred but it just goes right back. The other code settings, on the other hand, work just fine.

I'm wondering if it may be a sim card problem rather then a phone problem. I'm thinking I should try my girlfriend's sim. I'll report back when I see if that's the problem. It'll be after work though so feel free to come up with other suggestions. I plan to do a write up in general, [resolved] if we figure out the problem so people with this issue can know what to do.

Not the sim. I also contacted my service provider to get a push of their latest update with tower location, it's not prl on gsm it's id-something-something. No change there really as far as the signal issue goes. I also checked my provider website just to see how much data I had used, not even close to the cap on unlimited.
I think i'll have to try a flash on odin with repartition to a stock firmware and then work my way back to see what may have caused the problem. It's a shame, really since everything else on the phone works phenomenally, it just won't auto connect to hsdpa which is spotty in my home and work area so it's a bigger pain in the neck then it needs to be if it won't switch between the two on it's own.

[Q] Galaxy Mini (no 3G)

Hi Everyone,
I hope this is the right forum for the question, I've got my wife's Mini that I've flashed with TJ's Cyanogen release, everything went through just fine, and the phone is running much better then it was, the only problem is that I cant seem to get it to connect to the network via 3G, it will only connect via EDGE.
I'd appreciate any pointers in how to get this to work properly.
The phone was bought in Serbia, and was tested there with 3G, worked flawlessly, we reside in Canada and are on the Rogers network.
I've tried various network options via *#*#4636#*#* to no avail, it will only sync on EDGE.
Attached is the radio log from the device:
h**p://pastebin.com/kEBVVt1P
Many thanks in advance,
--aleks

i don't have that problem..
maybe you checked the "use only 2G networks" in settings-wireless&network settings-mobile network-uncheck use only 2G networks

nope, the 'use only 2G networks' is not ticked on.
Is there anything that I can force the phone to try and connect to 3G?

[Q] UMTS/EDGE Question

I have a problem with my Galaxy Mini. Correct me if I'm wrong, but there is only ONE version of the Galaxy Mini just different firmware, correct? Here's my problem, my phone is stuck on EDGE when its supposed to be on UMTS.. My GF and I both have the same phone, when I put my SIM in her phone I automatically get "H" and I rarely see "3G" (which is good). But when I put the SIM in my phone I ONLY get EDGE "E". Hers is from my countrys carrier and I got mine locally from a retailer unlocked (European Version). This is why I'm confused, if both phones are the same specs and everything why cant I get 3G/UMTS? I later found out we had different firmwares so I flashed mine with the same firmware as hers and still have the same problem. Could it be that I need to flash my Phone Modem with another one? (Idk..) All answers appreciated, Im desperate

Check if you don't have "Use only 2G networks" ticked.

Under mobile network connection there exist an option to only use 2g connections.
Take a look at. If the box is checked then unchecked it to use umts connections.
By the way. H connection is better than 3G.

I'd also like the point out that I'm computer savvy, I dont have "2G Network Only" checked

Maybe you can try to enter *#*#4636#*#* in the phone. You will get to Testing menu, choose Phone Information and then scroll down, there's an option like 'set preferred network' down there and you can choose WCDMA Only. Hope it helps...

[Q] S III mini network issue

Hi guys,
I own an i8190, baseband : I8190XXALJL and I encounter frequent network outage.
Although the signal strenght indicator shows 3-4 bars, I cannot be called, cannot call and data is not being fetched.
On battery usage app, the network is most of the time "green".
On any other phone around me (blackberries, iphones, SGS II and III), and on the same network the problem does not reproduce.
If I turn the phone to airplane mode, and then back on, I am able to call, send mails so on and so forth.
Does any of you have the same problem ?
If any of you updated to I8190XXALL2, is this problem still persisting ?
Should I send it to the service ?

I'm currently running the ALL2 baseband, but previously had both the ALJL and the ALK6 ones and didn't encounter any such issue...
Before sending it back you could try with a different SIM card, maybe yours is acting up (it sometimes happens, especially with old SIMs).
Seeing how nobody complained of a similar issue though, I don't think that changing your baseband will have an impact, but if you'd like to give it a try you can download original firmwares (that contain the baseband) from here: http://www.sammobile.com/firmware/. In order to install them, just follow the steps in the root thread.

Will do so. I'm going to pit-stop my SIM card @ Vodafone and let you know about it.
It's strange that this happens only deep inside buildings (eg. offices, malls, etc..).
When this happens, usually the data activity indicator disappears OR the S3 mini is using 3G frequencies (not H, not G, but 3G)

Just changed my sim card and the issue still persists...
It's driving me nuts. My feeling is that the S3 mini doesn't lock on a network cell when 2 are available with similar coverage.
Will upgrade to the latest build and let you know about it :banghead:

And now the handset runs XXALL2 from vodafone uk.
I'm curious if the phone will have that network issue furthermore.

So far there's no difference. Where I live the network coverage is pretty bad, but it doesn't "disconnect in the background".
Only at the office I can test it out for sure or inside massive buildings.
ci6i, go ahead and update; install kies (for drivers only ), get odin3 1.87 and flash it with XALL2 from samfirmware.
Lately I see there is XALL3 available for some asian countries.
I still think that my BlackBerry 9810 is a tank. unfortunately vodafone romania doesn't sync emails two ways via BIS so... :crying: I had to get back to samsungs...

Well, i understand to lose signal if network coverage is bad, but my phone gets "network stuck" in the middle of town. I noticed this few times: at job, the phone stands on the table near me, and i receive sms about missed calls (i have voice calls diverted to voice mail when unreachable). If i try to call or browse the net at this moment, it's impossible until i set airplane mode on then off. All this time, the phone shows full network signal and HSPA data connection.
I'll try to change the firmware after hollidays.

As mentioned above, try to change firmwares (to XXALL2), I've also noticed some network drops when I'm at home (however this is expected in my case), but when I installed this firmware, I noticed some signal gain (full on 2G and +1-2bars on 3G signal).

Hi again.
The same issue even on xall2
Just happened again today in a crowded place.
It goes to "3G" from "H" and then it's gone off the network.
Will try with XALL3 although there is a small improvement concerning "sticking to the network carrier". It seems it'a hard job to get a call when in coverage area...
If still no success, I'll loose my patience with this Sammy...
See ya!

You get SMS because they use a dedicated network bandwidth for this technology and apparently the S3 mini does not loose connection on this communixation channel.
It appears that S3 mini is dropping voice and data, but not sms and CB (cell broadcast).

LJL version. No drops. Sometimes when i am on edge of 3G coverage area

Hi, i also have the problem with vodafone Romania. I can't place calls or use data connection. After reboot everything is ok. I tried to switch to Airplane mode and back, but no results.

Hi bogdangr,
I have the same problem with my SIII mini. From time to time, after working normally, it loses the H or 3G symbol and shows about two or three signal bars, but if I try to make a call or receive one the operation fails miserably. The airplane mode trick doesn't work for me, and I have to reboot the phone to get it working again.
I've updated to the latest official firmware, but the problem is still there. Have you found a solution for this or anybody has more ideas of things to try?
Thanks you all,
MFC

I'm on VF RO, too.
Crappy phone, what can I say.
If it can't follow a network where there is sufficient coverage...

Hi Miguel,
The only workaround for this issue (at least for me) is to keep it in GSM mode (no "AUTO mode", no "WCDMA only").
So the crappy phone won't have to switch frequencies and I can get phone calls (I start considering a luck when the phone rings...)
I'm on 4.1.2 now baseband I8190DXALL3 (latest on samfirmware) and still the same.
You just don't want to know how's everything downloading limted to GPRS
BR,
Bogdan

Does anyone know what's that *# code that enables service / engineering mode ?
I want to select on which network frequencies is the phone allowed to work.
I want to disable 3G mode and leave GPRS, EDGE, and HS(D)PA only.
The reason is that when the issue appears, S3 mini switches from "H to 3G" and "G to 3G" and then it's gone;
Although there are moments when it can fetch data with network on 3G coverage without problems...

The code is *#*#info#*#* but it doesn't work .
I don't think it's a good ideea to disable those settings. Maybe it's a temporarily problem and i know Vodafone is testing/launching 4G coverage.
For me, this network issue is happening once in a week. How often do you lose phone signal ?

I found out the service code but the RF setup is not "sufforted".
Vodafone has implemeted already 4G in selected areas but it's not about that. On blackberry, iphone and nokia this is not happening.
As a frequency... 3-5 times a day while I'm at the office.
