3g off edge/gprs on

is this possible for android phones???
i want to turn off 3g since im having poor 3g reception and i believe this drains the battery faster...
i was able to swithch from 3g to edge/gprs(only) in my previous blackberry for push emails and turn the 3g on again when im at a good 3g coverage area
and do some heavy browsing
all i can find in my phone is "disable mobile data" well that means no data connection at all right???
any help guys??? thanks...

Menu/Settings/Wireless & Networks/Mobile Networks/Network Mode/GSM Only
I think will do it

It would be awesome if a one click widget for this toggle could be developed. Every day I find myself switching between 2G and 3G manually, repeatedly.

There is an App in the market called 2G-3G OnOff by Curvefish
Not direct switching but does reduce the number of selections.

Thanks for your suggestion... I've been using that for a while, so one click is what I was after like my other widgets.

Anyway to force only 3G?

Hi guys,
When I have roaming enabled and I'm not connect to 3G and only the GPRS I seem to miss alot of calls. Is there a way to only connect to APN if 3G is available?
Thanks

Settings -> Wireless and Networks -> Mobile Network Settings -> Connection type ->
It will be set on GSM/WCDMA, set it to WCDMA only

I have just tried this but I loose signal when WCDMA is only enabled?

Well that is 3G only, if you are losing signal it's because 3G isn't available where you are located, which is why your phone switches to GSM when given the chance.

I think you missed the OPs point!
What he means is that he only wants the phone to connect to the mobile network whilst in 3G coverage. i.e. he wants to keep the 2G/3G for voice and have the data only active when 3G is available.

Dave

Settings/Wirless & networks/Mobile networks Untick Data roaming.
Works for me on Three (H3G)

But this will stop data roaming all together? I still want it to sync auto
Thanks

That works on Three because Three doesn't have a 2G network. If you are on a network with both 2G and 3G networks (i.e. all the other UK carriers, not MVNOs), it won't do anything.

Hi guys,
Thanks for all the feedback. I have actually found an application on the market place called "3G only" it runs in the background and only allows you to use 3G and ignores GPRS. Works a treat!

How are you getting on with this app?
How are you finding this app?
So basically, you can only get "data" type stuff when you are in a 3g area?
Do you find your battery life is better?
What network are you on?
Thanx

Not really done much testing on the battery (not really kept on an eye on it) but basically it will only allow data to connect when I'm in a 3G area! Very useful as I have found I sometimes loose calls when it uses GPRS.
I'm on o2 in UK, Lincolnshire
Hope this helps!

Thanks for the reply, Im also on O2. I have installed it but havent tried it..i will do when i get round to it

Is there any way to disable automatic switching between UMTS and HSDPA?

In my apartment my G2 constantly switches back and forth between UMTS (3G) and HSDPA (H). Is there any way to stop this? Both look like they have the same number of bars, but it seems like UMTS is way slower. I also should be in a 4G market, so is there a way to tell if I'm on HSPA+ or not?

I've honestly never even seen the 3g icon on my g2. whenever im in kent, when it drops it drops from h, to E

I don't think the stock G2 ROM has a specific icon for 3G, if that's what your'e on. It shows H for 3G/HSPA/HSPA+.
I think the original poster is on Cyanogen, where it does show the type of connection a bit more accurately.

I'd also be interested in trying to force an HSPA connection. I don't think Bell has UMTS data so if I'm labeled as on 3G I can make calls and texts but have to wait for it to switch to H when I start using data.

It's a feature of cyanogenmod that it switches to 3G when heavy data is not required and switches to H+ when you need a faster data connection
That is of course if your running CM on your phone...

It's not a "feature" of CyanogenMod. This also happens on the stock ROM but we do not see the H icon, only the 3G one. Cyanogen himself explained this a while back.

You mean stock sees only the H icon, not the 3G one XD

Also note that if you're not actively using data, it'll show the 3G symbol (on Cyanogen or Sense ROMs) - as soon as you start a connection, it'll switch to an H. This isn't necessarily because the phone is switching between a 3G and HSPA signal, but rather because 3G is also used to carry voice - so if the phone isn't using HSPA for data, it obviously doesn't need to show it.

Thanks for all of the information, guys!

[Q] No 3g Download, only HSDPA or EDGE

Various apps (Facebook, Market, Head to Head & Internet Browser) will only download data when there is a connection to the HSDPA signal.
The 3G signal has shown as 3 or 4 bars but will consistently not download any data. Once the HSDPA signal is found, then the download starts. This can be frustrating as there isnt always a HSDPA signal.
i tried to insert another network provider sim card and it showed 3G and when i tried to launch for example browser it instantly changed to HSDPA icon and loaded pages so i didnt check anything... (i couldnt recreate a situation when only 3g was available, no HSDPA)
I currently am on DHD by baadnewz 1.7b but this also happend on Stock Desire Froyo.
any advices ?

HSDPA or High-Speed Downlink Packet Access is 3G..Actually enhanced 3G or 3.5G

if so, then why nothing downloads when 3G is showing ? if hsdpa is 3g and hsdpa works fine...

It's difficult to comment. If you're rooted, try another custom rom with an updated radio.

i have the newest radio

If the "3G" signe appears in your phone, this means that it's trying to connect to your carrier's network. Once you're identified your can start to use data connection, then you get "H" "E" or another depending on the technology used by your carrier.
H goes for HSDPA, E Edge and so on...
So the lagg time is when your carrier tries to search whether you've got acces to a data plan or not.

High battery usage when 3G enabled

Hello folks!
okay, the facts are: Im in very good 3g reception zone, MIUI 1.6.6 with default kernel, .08 radio, data on, wifi off.
Problem is poor battery life when 3G is enabled. Also, when using mobile data the H icon appears and data moves in and out, but sometimes the H icon just disappears and i get network error? I've tried numerous radio/kernel/rom combinations.
When i put airplanemode on, the battery consumption is constant 2mA (currentwidget). With 2G networks only, its 3-6mA. When 3G enabled, mostly the consumption is 20-40mA and sometimes like 10 times in day with minute interval of refreshing i get 8mA readigs. Any app to check if there is some syncing going on? I use only beautyful widgets weather widget, which updates itself hourly. And the normal contacts and calendar sync on. Fellow MIUI users have much lower consumption, a mate of mine gets 2-4mA when 3g enabled.

3g mobile network is one the battery killers. The h icon stands for hsdpa. This the fastest network but the network coverage is not that good yet (except for big cities). Switch network to 2g network (mobile off). If you really need mobile network, switch on 3g. Otherwise stay with 2g. There's imho no sense in using 3g without needing/using mobile network.

I tried using BatteryFu and APNdroid to get rid of my 3G while screen off. But that combination didnt work so well, sometimes it didnt disable my 3g and sometimes it wouldnt reconnect to 3G when unlocked. Any good programs to manage this?
I also wonder, I never cant download anything when 3G icon is appearing in statusbar. Its normally 3G but when I want to use the internet, it changes to H. Why cant I use the 3G network then? Im also having problems when the H goes to 3G the internet connection is lost. For example in market i get network error. The H wont stay there if there is no traffic for few secs.

Configured apn correctly? If you are not sure, do it again. Furthermore, you could try these settings for mobile network:
Uncheck data enabled and set network to 2g/gsm (depending on what you have). When you need mobile network, switch to "wcmda + gsm (automatically)" (name could be a litte different, translated it from germany) and check data enabled. I do it so and it's working fine.

Okay didnt understand very well what u ment by the last part of ur message
APN configured correctly? I have carrier default APN settings which have been working just fine for a year. If u ment APNdroid i didnt do much configuring with it. Gotta give it another try.

Last idea: flash latest radio.
