Orange UK 3G problem?

Is anyone else having any problems with their data connections on orange in the UK?
I've only just noticed that i have on data connection at all.
At first i thought it was because i set my wireless lan settings to a static ip. But changing it back does not bring my 3G back.
Then i remembered i upgraded from darkys rom 9.3 to 9.4 so thought maybe it was the modem included in the update. But i just changed the modem back to zpg and still no luck.
I have data turned on in the settings, But when i go to the about screen it says disconnected.
Im sure my settings are right, and i sent a picture message this afternoon which was delivered ok.
Im at a loss as what to try next?
Anyone else have any ideas.

Panic over. Data connection is back. Although only 2G, so it looks like orange are having problems again.

Yeah, been having the same issues too. I'm wondering if we're better turning off the data roaming I had enabled to allow me onto T-Mobile's network.
Orange and t-mobile dont share their 3G networks as of yet only the 2G.
Still having problems here.
But thankfully its the network and not my phone!

[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:

Many thanks in advance,

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?

Enabling HSDPA on Jelly Bean

Hello guys
I have been performing various rom installation on my Samsung Galaxy S GT i9000 but everytime it was only GingerBread Based roms.
The second i switched from to ICS and to CM10 JB now, the problem i have been facing is network mode option which is not present in GT i9000 when i was on ICS and also in the present CM10 JB.
I tried many thing but none worked
NOT WORKING
again tried to enter the code *#301279# but that also dint worked.
And my network is 3G enabled since i have tested the same sim on my another phone which is a SGS II running on stock ICS and 3G is working perfectly fine on it.
So basically to enable 3G on my I9000 i would need to change my network mode which at present is not available in my mobile network settings.
HELP ME OUT.........!!!!!!!!!!!!

I must say that you din't even helped me with your statement as i feel you haven't read my problem properly. We have the best network signal availability in my area at present and as i said 3G is working perfectly fine on my sgs II which i already mentioned because i'm able to select the network mode manually from the mobile network in wireless & networks settings.
And not to forget the sim i used for testing 3G on my SGS II in actual belongs to my secondary phone - SGS GT i9000 which is currently running rooted and Running on CynogenMod 10 which is in alpha stage,
And for the data usage on - dude i'm no noob to post this question without me knowing how to use a phone properly.
And hey i did have my data usage on but in that attachment the data usage was off and it was just to show that there is no network mode selection available in the mobile networks settings.
I HOPE YOU GET IT

Try to switch your mobile network mode to "GSM only" and then back to "GSM/CDMA auto". Try rebooting your phone, clearing cache/dalvik or fixing permissions.
Also, as far as I know, some ROMs do not support auto switch between 3G and HSPA (3G icon is displayed all the time). Usually custom ROMs switch between H and 3G to save power (H is used only when bigger network traffic occurs, in order to speed up your download speed), but many ROMs do not have this feature.
Forcing 2g, rebooting, etc., doesnt worked. I know that H is used for big traffic, but ICS dont even want to enter it when i download 10mb+ files..
hey there
as u might have seen im on eplus too and i faced such an issue several times with different phones
what i figured out was that in some cm9 roms the mobile hotspot (dein zugangspunkt ist ja normalerweise glaub ich internet.eplus.de ) is not available or there are mistakes in it so just get to the eplus providers homepage and check if ure zugangspunktname and all the other options dealing with it are set right
hauste rein
Everything was ok, now i changed back to gigabread+ from texten...
HSDPA works fine, seems so that ics is blocking connection like divibyzero said.
ICS doesn't block it you probably need to set up your APN correctly which is what I think the guy before me was saying too

Restarting the phone or reinstating the simcard does not work or solve the problem...

Hi there. I also own C6602 (13W07). I'm from europe (GSM 800/1800/etc.) and got the same problem.
Selecting the only option ("USA Band") in *#*#INFO#*#* switched off the ability to find network.
SIM contacts are still available. So sim card must not be dead.
Also had a side-effect: clicking on almost every application icon works after a long lag (or after a 10th click)
And as a side-effect-II: possibly disapeared ability to use built-in "CD-disk with Sony PC Companion Software" when connected to PC with USB cable
Restarting, changing band in other menus, Airplane on/off not helped a lot.
Have a guess that *MAGIC* hardreset will solve this but not tried 'cause i'm not syncronized yet
Haven't seen you for a while. Did you solve your problem?
