sounds like you need your APN settings
go to settings -> > more settings then mobile networks-> APN check and see if you have the right settings for your carrier

You have a very old Gingerbread baseband from september last year. LPS works excellent, I'd give it a try.
Downloading LPS now from this thread
http://forum.xda-developers.com/showthread.php?t=1131950&page=105
does Vodafone has any different modem for SGS2?
Still facing same issue upgraded modem LPS Its still the same.
Strange thing is Use 2G network and Data Enabled is unchecked itself whenever I had this problem.

There are a larhe number of modems .
Start with the last one and work your way back .

Best way to find a good Modem is testing them all.

You need a computer and a thing called search and you look on XDA thread for Modem post with flashable modems .Like most stuff its found in development .
But you would do better to read the basics first .

[ROM] XperiaTized V10 GT-Xperia S on DDKQ8

I flashed the "XperiaTized V10 GT-Xperia S" ROM on my Samsung galaxy Ace which has a baseband version of DDKQ8. Everything works fine except the 2G network. Anyone faced issue from India? I really liked the ROM and want to use it. Unfortunately I cannot post my problem on development thread as it is blocked for me.
If anyone even has a work around let me know.
Wait fa few hours....may b nw prob..

No, no problems like that. Reflash it again.
Sent from my GT-S5830 using xda premium
Ohh ok thanks for the quick reply. Let me reflash it again. I was moved to CM7.2 RC3 due to that bug. ROM is so good that I keep coming back to it again
i thought XperiaTized had A APN problem
i think you might need to add the apn manually
Thanks a lot everyone. I manually added the APN and now 2G is working fine.
Btw... this ROM rocks, it is beautiful and smooth!
problen with mobile network

well, it is a different phone. a small difference in the Model no. itself can result in a different phone. There must be some little difference of chip or something in it from the original 5830....

Abou that... You are wrong
I have the GT-S5830L and is the same, the only difference it exists is that the L version has either lower or higher frecuency in band (internet) and that L means latin american
He must use Stock ROMs for GT-S5830L because that frecuency number can make the difference connecting through 2G.

Hsdpa/3g switching issues

First off phone is stock and un rooted.
My issue is that the phone will switch to 3g or E so much and then often not switch to H when I use an app requiring Internet so the app won't load anything. Anyone else have these issues or is there a fix? I'm in Australia btw.

If your phone is unrooted, there are limited things you can do to solve it. If it is rooted, you can actually try to flash different modems for your phone and see which one works best for you or just find out from this forum what modem is best for your carrier.

Sorry, I have looked around and you can actually flash modem through Odin if your phone is unrooted.
Oh really?? Thanks for letting me know, I haven't messed with flashing before so I doubt I will now haha i might wait for official updates...

Most official modems for my region are terrible, I'll bet your's aren't better. Asian modems have a far greater stability, especially the DXLF3 modem.
You can't do anything wrong when flashing a modem. Just get Odin, head to the modem collection thread, pick your modem and flash away.

Sounds like antenna ping-pong. Basically that means that your carrier keeps moving you from one antenna to the other.
Alternatively, check if you have any Proxy configured in the APN settings as slow proxies can cause the same issue: go to Settings->More->Mobile network->Access point names, choose the one reading 'internet' (or something like that)
Check if any Proxy server IP is filled in. If yes, write it down and delete it from the profile. If Internet doesn't work, reconfigure it.
If it's better, congrats
Oh really! I didn't realise the Asian modems would work well in Australia thought they would be specific to region, obviously not! I will try the flash if nothing else works..
I checked in the settings like u asked but there is nothing under proxy? Should here be an ip is that the possible problem?

Wcdma only still switches between 3g and H, trying it now. So it wouldn't make a difference would it?

there is still difference in term of speed between 3g and H. if you want consistent H+, change modem to BWLE5, if you not in LFB based rom.

with this modem, your phone will go straight from 3g to H+, it doesn't even know H anymore. lol. try it to feel the drain on your own.
I had the same problem with lfb modem on stock lfb rom. I fixed it by flashing lf2 modem.
Try it. If it doesn't work flash back the modem you had before.

LF2 is older than LFB. Are you sure voice calls still work?
I still recommend DXLF3 modem ^^

How do you test modem ?

Hey, I'm new android user here

NO. Manually only, flash modems from here http://forum.xda-developers.com/showthread.php?p=28033515 , one by one every couple of days. Watch your signal bars and run few speed tests. Strong signal doesn't mean fast data. It's all depends where are you and who is your network provider. Have a fun

First check you are on gsm mode or not. If not select gsm.
Secondly
Change the baseband
