3G problem ?? - Android Software Development

hi guys ..
i have desire .. and have problem with 3g ?
that i only want to open it when i want to open ?? NOT to be open all the time ??
and i have to sing at top >> E and G ?? what the diffrance ?
AND in mobile Network .. there's GSM and WCDMA ?? mean what ??​

honestly, I haven't the slightest clue what you are trying to ask
but anyway..
I believe E stands for EDGE and G stand GPRS
I believe a gsm network is a type of voice network while wcdma, is specifically for data. You wouldn't see wcdma without gsm. I could be wrong on that though..
I don't know if this is what you were trying to ask, but you can turn off mobile data by going to settings -> wireless networks -> mobile networks -> Data enabled
alternatively, you could download apndroid from the market.

[Problem]Unable to connect to wcdma network

Hi guys from 2-3 weeks I'm unable to connect to wcdma network that means the mobile shows only E(Edge) sign but NO H(HSDPA) sign. I have cm7(2.3.5) rom and baseband switcher 4.0. I had no problem using the wcdma n/w but suddenly it's not accessible and I'm stuck with this slow edge n/w. Help me ouy guys its hard to live without internet.
setings/ wireles network/ mobile network:
and here you find 2G network checked (uncheck),
and option: wcdma, gsm/wcdma, gsm
use what you need

Come on.. I'm not a newbie. I know all the settings. I have posted this question because after all the settings correct, still I'm getting this problem.

T-mobile Internet Frequency

I have a Samsung I9000 and recently added internet onto my plan, though it only says edge internet. Is there anyway to get it to 3g?
Which country? You never rooted your device and also didn't plan it? Which modem?
Maybe you can check if your phone is forced on 2g!
Go to Settings -> Wireless -> Mobile -> Network (sorry i got i9001 italian! )
Here i can choose between:
_GSM (2g)
_WCDMA (3g)
_Auto GSM/WCDMA (3g, but switch on 2g when there's no signal)
If you have GSM or "2g only" that's the problem
Its a GT-I9003, I do not know what country it is from and I tried the network function it only gives me 2G stills.
Is it possible to get 3g on this phone??
I'll try to explain in different way
Follow the 4-step i made in attached image, what do you see?
(last image show what you should choose to have 3g network)
As you can see on gsmarena (sorry i cannot post links), your phone is theoretically perfectly able to use 3g!

How to use 3G in ICS 4.0

Network type selection : 3G preferred.
Network mode : GSM/WCDMA preferred.
same with ROM 2.3, but no 3G connection, only E (EDGE)
You just answered your own question. 3g PREFERRED <<< try to use 3g only?
Sent from my U8800 using XDA
but in that case if he goes to a place that doesnt have 3g cover he doesnt have networks...
near my home i have so many places where that happens... even got no network at all...
so 3g prefered its the best option i guess...
Yes. Rom 2.3 i have 3g network everywhere. But 4.0 sometime no signal.

Not really, never even thought about disabling LTE before I read your post, but I had found Tab/List view feature for the System Settings after I started monkeying around with phone, got it on Monday BTW...
When you have the System Settings open, tap the menu button to select between list and tab views. I like list because it puts most things in order similar to my ol' Samsung phones. :good:

hi same problem
i have installed italy rom and it says >>> EURO "D80220b-Euro-xx" and
no lte option
lte only says " not supported" in hidden menu
no knok code
i have also tested german >> "D80220D-euro-xx"
no lte option
lte only says " not supported" in hidden menu
knock code avilable
ALL of voice software say "unfortunately stopped working"
i think no lte most be one of these things
1-your phone IMEI
2-your phone rom
3-your network provider
OR MANY of these
finally my solution : after buying many LG product i found LG is such a waste of money now ... i am going for Samsung or htc

Try this:
More networks -> Mobile networks -> Network mode
Switch to WCDMA/GSM (auto connect)
Check results
Maybe your SIM does not support LTE, so phone blocks completly (we had such situation on both SGS 4 and SGS 5 with several baseband versions, provider dependent)

Thank You for ur reply
i already switch to wcdma/gsm many times but nothing works ( the SIM Card already work for me in S3 Neo with H+ )
the problem is when i select Only GSM the network work fine and it show E or G in DATA MOBILE
but when i select Only WCDMA the signal force replaced by Block and nothing work until i back to WCDMA/GSM
i think may be the frimware is only for UK and i need to remplace it by a other frimware ?
Ah, but AFAIK, WCDMA will work only on some networks in USA.
I am not aware of any other country using WCDMA...
