Please help with 3g - Galaxy S II Q&A, Help & Troubleshooting

I can't get any internet when on g or 3g only when on h. I don't know what's going on. I'm on the latest update. Oh and I'm with Vodafone.
Thanksbkn advance, jay

That is normal when on GSM you only get Edge (E or G) when on WCDMA you get 3G HSDPA connection speeds depending on your contry and zone (ofcorse on the antenna in that area).

No, I'm on auto mode so it selects itself. Its just when the signal drops from a H signal to a 3G signal or a G signal and that's what is displayed on my phone then no internet can be accessed at all. The phone connection is still fine, just internet or anything that uses internet connection, won't load.
I hope that makes more sense

3G signal on x10i

Right I got me a bit of an issue.
Dunno if it's been covered by someone already, but there's only so much the search bar can do from my phone.
I am using X10i I am on O2-uk
Even when I am sat next to someone that has full 3G signal, I am totally unable to get anything.
I've had this phone for just a year now an idea have never had a 3G signal. The best I can do is get H
The status bar claims to have 3G bit as soon as I try an use the connection, for ANY reason, it instantly switches back over to H
So basically my issue is........ WTF!?!?
Why not ant I connect to through 3G? And does anyone else have this problem? Is there fix for it? An app or something I'm missing?

The infamous "H" ...
From what I understand H is better than 3G...in fact its 3.5G! Increased download speeds when compared to regular 3G..
"H"is a good thing..

Really? If that's the case then I should have seen 3G at some point in the last year when I had worse signal???

Nope. Afaik 3g depends on availability in your area. Not related to signal strength.

Yeah mate the h is for hsdpa which is, as said above, better than 3g.
Edit: if phone can't get hsdpa it will go for 3g. If it can't get 3g it will search for edge (will just have an e). If it can't get e then u need to stop living on mars as u ain't got no mobile internet.

You can't really complain some people have issues even getting 2g while your having 3.5g

Ok
Thanks guys. I was under the impression 3G was better than H
Cheers for clearing that up

3g connection?

I am not sure I have an issue or not in all honesty. I have flashed to the new baseband on my lg optimus t. I am using hephappys ics 9.1.4 but I never get a 3g icon. My connect speeds on mobile network show a h symbol and are about 2Meg down by 126 k upload. I am not really sure what I should see for a 3g connection.

Google and read more about 3G and H.
H stands for HSDPA.. means 3.5G basically faster than 3G.
Good to know. My stock rom must have just shown 3g instead.
I am surprised that updating the baseband has improved the signal as much as it did. I went from 2bars to 4 bars.
It's also nice to not have to flash a rom then flash the baseband fix.

Activating 3G

Hello, I have a galaxy s2 running 4.2.2 jelly bean and I'd like to know how to use 3g networks. When I activate data in the notification bar I have the H icon instead of 3g and I don't know why...
Sent from my GT-I9100 using xda app-developers app
H is HSDPA which offers faster data speeds than vanilla 3G. Most networks will leave your connection @ 3G when it's idling (I.E you're connected but not pulling/pushing data) & will ramp up to higher speeds automatically when it detects you start moving data on the connection again.
I see, really didn't know that. Thank you

Network settings and questions

I'm a bit confused on the network settings. For example GSM/wcdma,which should I use or leave it to both? What exactly is wcdma? Also on select preffered network do I want GSM or the uxxx (whatever the other is)? As is I get great 4g when I'm out and about but at home my phone just sits with an x in place of signal. Seems it should switch to 2g (is that what T-Mobile calls 3g?) Or g. It occasionally will with good signal but drop it immediately ....

The 4636 menu doesn't do anything on my phone. And the service menu just gives me an error when I go to service providers. This 2g is definitely not 3g its ungodly slow!

Strangest thing, while I was trying to unlock the bootloader with the open (euro?) Version I flashed the radio for it and got 3g and hspa. Only time I've seen it, back on usual jellybean w latest baseband and its 4g or 2g again.

(Question) only h+ instead of 3g

Does anyone know a method just to stick with h+ data signals instead of switching to 3g.
Fyi in my area 3g reception is poor n always toggle between h+ n 3g.
The h+ signal is pretty good n it's enough for use also.
Therefore I thought if I can stick with h+ it will save my battery life.
Please comment your idea or solution.
Thnx in advance

You can only set your phone to your mobile providers Mobile Data capabilities. It is not something you can set to work at just h+... this depends on the strength of your carrier in the particular area you are at. Your phone will pick up the best signal it can. Mine also goes back and forth, depending where my location is... and the building structure I'm at (and how much interference there is between buildings, etc)... unless it's some hardware you can attach (like antenna on inside of back cover) to boost signal.
I remember for my S2 device... someone posted a way to just have a certain mobile data signal... but it didn't really work, just had the symbol, but obviously still can only get what my phone was able to pick up.
If someone else knows a solution I haven't heard of, would like to hear it.
Oh thnx.
Plus no one will try to create a mod to use the less power signal instead of 3g. So seems like this is it.
But my idea was if a developer can make a mod to stop looking for better signals after achieving h+ that's it.

Lol... H+ stands for hsdpa/hspa ...it is 3.5g...faster than 3g
The phone runs on H+ during data usage and 3g for calls

Unfortunately there are no ways reported for 3g and H+ toggle as far as I know
Only 2g to 3g toggle is known

When there no data transfer it will show 3g and when data is being used it will show h+ or h

Using sevice mode to select HSPA only, no UMTS ( 3G )
