Lost Data Connection! - Galaxy S I9000 Q&A, Help & Troubleshooting

3G and H are appearing but nothings happening, no activity. This is after a data\cache wipe. Any fix or do I need to flash again?

Check your apn settings. Also, try searching for your network provider.

It's set to orange internet, network provider is set to orange.

dial *#*2263* and make sure all the bands are selected (go under combi bands and select them all). Other than that, not sure.

That's not doing anything on my phone, you sure that works with froyo?
Nevermind, tried sgs tool, all are selected... Still not working..
Ps: swype is awesome.

Get the exact APN name from Orange and make sure it's set for internet.
Sometimes, telcos have multiple APN settings.

What he said. Sorry I got the code wrong, I was going from memory. Failing that (apn check), you may have to reflash, but I'd see if you can get some insight from someone a little more experienced than me

maybe he updated to froyo and lost his imei

Don't understand why but it appears to be working now, I also tried it this morning with no luck maybe it's due to location, but it was working fine before...
Very strange, will try later today and see if it's still working.

Shortly after getting home, got no service message, after reconnecting to network the 3G connection is dead again.
I'll reflash later, this isnt right..

Exactly the same after being flashed and reseting everything to defaults, this is great.
Last time I touch clockwork recovery.
Can't even make any calls now , either the sim cards messed up or the phone is...
I'm starting to hate this phone.

3G not working but 2G is :S

Guys my phone will not work whilst on 3G. If I switch to 2G all is good.
What is happening?
I rang vodafone and they said nothing is wrong with my account.
I have even done a full wipe and tried a various number of cyans ROM's including the new experimental but still the same issue.
Check APN settings all look good so i'm a bit stuck

APN has nothing to do with it.
No signal? Could be THEY have a bad transceiver. Or there's a lead wall between it and you.

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).

Andromeda 3G problem

I flashed Andromeda 3 2 days ago with Darkfire theme. I love this ROM and theme except for one problem. The coverage I get doesnt show 3G. It just has the bars. I can send text messages and phone fine, but when I try and email someone, or try and use GPS or the internet, I cant because it says I have no network coverage. Can anyone help?
This happened with me when I installed Andromeda 2 a couple months ago and was the reason I installed something else.
bad APN or you have Data turned off in your Power menu. Check your APN and make sure its registering on the network

How do I go about checking the APN and making sure the data is turned on. Im a newb
Hold your power button for a couple of seconds and the 2nd menu item down will tell you if the data network is activated or not.
As far as the APN, I think that you could check that under settings--wireless and networks--mobile networks. I'm sure someone will let me know if I'm wrong about that
Please use the sticky, that's what they're here for.

AT&T Tab will no longer connect to AT&T data

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?
Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.
Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.
Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.
I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.
Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.
It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?
Yes, I have voice and 3g data by ising a sim from my old android phone.

Resetting 'band' setting changed from test *#*#info#*#* menu?

The short:
I changed the "Select radio band" setting in the test menu (*#*#info#*#*) and it screwed things up.
I wiped and reflashed CM12.1 - but it didn't reset that setting (it's still borked).
Does anyone know where it stores that setting, or how to reset it somehow?
The long:
Initially in CM12.1 I was having problems staying on LTE - it always fell back to 3G and stayed there.
So tried this band change that someone who had the same problem suggested.
Now, every option I try is great for LTE but says "cellular network not available" and I can't make calls.
The exception is "Cellular" which I can make calls but only get 1X data.
These are the options in the menu:
"JAPAN Band (WCDMA-800/WCDMA-IMT-2000)"
"USA Band (GSM-850/PCS-1900/wCDMA-850/WCDMA-PCS-1900)"
"Cellular (800-MHz)"
"PCS (1900-MHz)"
I don't know what it was before and I can't see figure out how to tell what it currently is set to.
I just want to flash back to stock so things work again, but if this setting doesn't get reset then I don't know if that will work anyway.
Any chance settings like that are stored on the SIM card?

Worth a shot, but doesn't seem to have helped.
Try the instructions here: http://forum.xda-developers.com/showthread.php?p=57778872
I seemed to have luck when I made the changes according to this post and then immediately ran the ping test. I don't know if the ping test really did anything to help but I've had cell service since following these steps.

Unfortunately that's what I did initially. The setting in that link ("Cellular") made my calls work, but I could only get 1X data.
So somehow by just flashing and reflashing different things (including failing to reflash to stock), it's back to where it was when I started.... which sucks, but is at least useable. Calls work and data works, but the first time it has to drop back from LTE to 3G, it get stuck in 3G forever (until airplane mode). Super sucks since it's my primary home router tethered. I have to airplane mode like 5 times a day.
Just in case someone else ran into this problem, I ended up getting a new sim from Verizon and everything's working now finally. It still says "000000" when it's in 3G, but I don't care about that - it works and it goes back to LTE when it can, rather than staying on 3G forever.
Works for Moto X play - should work for others too..
I too did the same mistake. Changed my Band to "USA" and couldn't restore to previous despite Factory reset.
The SIM 1 went into 4G data only (No voice) , didn't recognize 2G & 3G network for any sim.
However Sim 2 worked fine for 2G,3G & 4G.
i came across a thread in XDA, and after breaking my head over how to execute it, I finally did it.
I have written a brief guide to it. Here's the link.
