how to force internet connection to use 3G/HSDPA only?

is there a program to do that for windows mobile? so that the connection wont fall back to gprs or edge and always use 3G or hsdpa?
in sierra wireless aircard there is an option to set that.

i think there's an option in setting, personal, phone
go to band tab and change network type to WCDMA and change band to UMTS

it works but now phone call also using the 3G network always. how to set only if making data call?

If you want to do this band change easyly, can use the tools on
this post, if you want the phone change band smartly, better you flash a good WM6.5 ROM.
Check more info on this thread.

i have a similar question but it is related to forcing the phone to switch from 3G to HSDPA mode when active data transfer occurs..
thanks..

Data constipation? Irregular data movements? Constant disconnects?

Symptoms
- You cannot maintain a constant data connection. The connection is often lost or dropped.
- HD2 reception indicator dances between G to 3G to H despite showing good reception, and user remaining stationary.
Counter measures - No cabs or registry tweaks needed.
Presented in the order I would try them. If the lower number levels don't work, then move up a level. These are offerred as advice from a UK based HD2 user, though may work for you elsewhere.
LEVEL 1
- Go to Comm Manager > Wireless Controls
- Turn the Data connection Off then On again.
This will usually get you back and running again faster than waiting for the HD2 to sort itself out.
LEVEL 2
- Go to Settings > All Settings > Connections > Advanced Network
- Disable HSDPA/HSUPA
This will stop your phone attempting to use '3.5G' and will mean that you only use 3G.
Remember to re-enable HSDPA/HSUPA when you are in an area with better reception.
LEVEL 3
- Go to Settings > Wireless Controls > Phone - Change phone settings
- Move down to Other Options > Band - Change baseband
- Change Network Type from Auto to GSM
- Change Band frequency from Auto to either GSM (900+1800)+UMTS or GSM (1900+850) . To make the decision, you need to know the GSM frequency your operator uses. If you don't know, you can just try both of the GSM options and see which works. No damage will be done by using the wrong frequency first time, and you can change back.
This will disable 3G and force your phone to use 2G. Most operators have decent 2G networks, so you shouldn't have the disconnects anymore, but you will have slower than 3G potential speeds.
Remember to change your phone back to Auto for both Network Type and Band Frequency when you are in an area with better reception.

Thanks for the heads up... will have to try some of these. I find it most annoying at times...!

Thanks for the advice, I do find those issues annoying. What are the benefits of using 3.5G? If they're aren't any major advantages and turning this off helps then I may as well leave it off.

The problem with this is that it b*llockses up your push email settings, if you use the phone to get email from an Exchange server. The better approach (assuming standard configuration) is to press and hold the power/end-call hard-button. That brings up a menu of four choices. The last of those is "terminate data connection". Click it. Anything the phone does which requires the data connection after that will automatically reactivate it.

3G 2100
These tricks may solve the issue for many but not for me because I'm in a 3G 2100 only network so I cannot switch to GSM. I will try to disable HSDPA/HSUPA to see if that works though.
The weird thing is that the issue occurs almost exclusively when I'm logged on an IM client and the phone stays in sleep mode a few minutes (say 15 min or so). After I wake up the phone the signal seems ok but the data connection is lost (IM, browsing, mail, weather update, etc.). It doesn't happen every time but very often, several times a day.
If I don't log on any instant messenger app the data connection is stable, especially with the new 1.66 ROM (I tried both Duttty's custom and official). In this case I lose data connection very rarely, in fact I din't even remember the last time I did.
Can anybody provide an explanation for this, what is happening with the connection between the IM server and the phone during sleep?

If your network supports it, you should have higher potential data upload and download speeds through using 3.5G (HSDPA/HSUPA).
In reality and every day use, on many networks you probably wouldn't notice the difference between 3G and 3.5G.
I'm on Virgin Mobile, which piggybacks on T-Mobile's network here in the UK. My speedtests in central London, show virtually no difference between me using 2G, 3G and 3.5G!!!! Which is ridiculous. The main difference I get as a HD2 user is much more stable data connection on 2G vs 3G/3.5G.

prevent 3G on cdma?

3G has become the clearest battery drain outside of screen usage, so I'm desperately looking for an app to shut it off when I travel for my Droid. I know that for some reason this could not be developed for Verizon like other networks because of the CDMA network, but I would imagine that a solution could be developed for rooted users since getting a Wifi signal essentially turns off 3G while still allowing for texts and calls? Could the phone be tricked into thinking it has connected to a Wifi signal? I'd pay for an app like this and I think others would too....

Go to the dialer and enter: *#*#INFO#*#*
Then go to Phone Information. Then scroll down to where it says "Set preferred network type:" and change it from CDMA auto (PRL) to CDMA only.

try juice defender in the market. it basically turnes off 3G while the phone is locked saving a ton of battery life! when you unlock the phone it turnes 3G back on! only problem is it takes a little while sometime for 3G to kick back on... but you could enable the juice defender when you want and disable it when you dont need the extra batttery life! give it a try! its free so if ya dont like it you can just get rid of it!

You can also use Quick Settings which among the other settings you can quickly change allows you to disable the use of 3G. It works great on my Milestone.

Or you could use APNDroid (on the market too). It has a widget to manually switch on/off the 3G net, but still allowing to use the phone/text.

Your milestone is GSM. Quick settings does not work for CDMA phones.
To the OP, use the widget called Easy Switch. It does 3G and GPS (among other things) with the click of the button. It doesn't take you to an options menu, it just works.

+1 on APNDroid. Simple and just works.

Another option for droid is cyanogen6. I know rc2 has 3g on/off built into droids power control widget.

use cynaogen...u can turn off 3g in there

Mobile data problems

Ok, Ive always had crappy 3g on my x10 but i put it down to signal issues, i thought i was in a poor 3g area.
I noticed whilst playing around in the settings that i could set the phone from WCDMA only, whereas before it was GSM with WCDMA preferred.
This sorted the problem out perfectly, great 3g performance even with crappy signal, the problem is that for some reason this means when there is no 3g signal it doesnt just fallback to GSM for voice.
From what i have read on the net it seems like changing to WCDMA only should -only- affect the data connection, not the phones voice connection.
Am i doing something wrong?
Is there a way that i can force the phone to use 3G only for data, but still use GSM for voice?
Thanks

in that case you should set the settings to like this 1. wireless controls 2. mobile network 3. network mode "WCDMA" then 4. network operator then search network tap the available current network what u r using do not select the automatically 5. done
after that turn off the phone remove the simcard for 5 sec. then turn on again wala u have 3 to 4 signals on ur 3g connection....

Thanks for the tip, it didnt work, but thanks

I have GSM/WCDMA selected but data unchecked and still works great

Anyone know what app can manage data and mms? I mean I don't want data connection but I still want mms enable.
Thanks

ouch, seriously doubt that's possible on the x10
maybe deleting the 3g APN or creating a blank one and just selecting the right mms one

Isn't MMS dependent on data?

It is but you can create 2 APNs one for data and one for MMS and after enable/disable the data APN on case by case needs
At least i think it works on rogers because i saw separate settings for MMS only.

I am confused too. Hohoho... But as I remember, previous phones (such as X1,X2,p990) did have this options. Correct me if I am wrong. Because I always connect internet/browsing using wifi. Except mms.

[Q] No data connection when switching between gsm and wcdma

Hello!
I'm using Rafdroid HD von my HD2 now for 2 weeks and I'm verry happy with it, i just have one problem (dont know if it depends on de android build or on the hd2 or whatever...)
I'm using gsm all the time because it has less battery drain in stand by, but when i want to use data for surfing etc. i switch to wcdma. on my x8 wich i had before this was no problem, it switched within seconds between the networks. Also the HD2, BUT it doenst start a data connection. i just can talk but no data.
in "wireless and network" the option for wireless data is checked, but the whole option is not clickable and it says "starting" (dont know if it says starting, i use the german version, there it say "einschalten..."
when i restart the hd2 then the data connection is working. so all times when i want to switch the data connection i need to restart my hd2.
is there a way to solve this problem?
sorry, i've searched the forum, but i haven't found anything
thanks and best regards, chris

No one who knows something about this issue?

tried this yet??
enter: *#*#4636#*#* in your dialer
go to phone info
go all the way down
now you can manually switch between edge or 3G
(default should be WCDMA preferred)

Thank you, I've foudn this idea before but it doenst change anything.
I'm using the whole day only gsm/edge, but when i need more data (searching something on google etc.) i would like to switch to 3g. after this, back to wcdma. on my x8 this worked well, on the hd2 it looks like it cant start the data connection when switching between the two types of network...

Same here,
when running runnymede rom from dung my phone switches to WCDMA (in *#*#4636#*#*; because of this I have no data connection 3G or HSDPA. When switching back to GSM only data conncetion (3G or HSDPA) is working but after a while phone switches back to WCDMA preffered.. How to change this into GSM only as default???
