Force Android to use ONLY 3G?

Hi
Is their anyway I could force android to use ONLY the 3G UMTS network ? it keeps jumping to 2g randomly and the download speed drops from 500kb/s to 15 !!!! So its really pissing me off.
If anyone has ANY idea how to do this, please let me know

Well sometimes 3G networks aren't available and your phone can't connect to them. So it uses 2G networks to preserve the download and the connection

Download Any Cut from the market.
Make a short cut using Activity.
Select Phone Info.
Select from the drop down list towards the bottom "WCDMA only".

there is an option on the hero rom to use only 3g networks

If you did this and were downloading something you would get tons of dropped connections. T-Mobiles 3G is still kinda in its beginning stages and isn't near as available or reliable as the bigger networks (Sprint/verizon/AT&T)

Dude.....YOUR A GENIUS
Thanks abunch for the suggestion !! Yea..it worked just fine
I would have never guessed that one !!
Thanks to everyone else who contributed ! appreciate your help !.
The reason I wanted this is because my G1 sometimes suddenly drops the 3G and goes to 2g in a zone where 3G signal is excellent and im downloading at 400kb.s but for some wierd reason it switches to 2G and I have to wait untill it decides to switch back to 3G. But thats solved now.......FINALLY

That makes sense. I'll have to keep that in mind when STL eventually gets damn 3G

thank you!!!
On my operator (italian - TIM) i was going from 4mbit to 8kbit on "edge"
my operator thanks you also (as i was going to switch to another operator with better coverage)

Set phone for only 3G (WCDMA)
There is yet another way...
From the dialer, type exactly:
*#*#4636#*#*
After a moment, a screen will appear called "Testing". Select the drop-down that says "Phone Information". From there, scroll down to where it should say "WCDMA preferred", and change it to "WCDMA only". Use the back key to get out. It should stay selected even through a reboot.
​This works on CRC1 (the latest US 1.5 "Cupcake" ROM) but I can't say for sure if it will work for other phones (myTouch) or other markets (UK).
It's essentially the same as AnyCut/BetterCut, you're just using a different way to get there. This uses more battery than 2G (GSM), but everyone already knew that, right?
HTH!

I tried this with Internet Radio in the Car and it seem to cut out less often, just wondered if there was any other way to increase the 3G signal on the phone as it has not external connector for a 3g antenna, is it possible to solder a connector in, is there any know mod, it would be so cool to listen to internet radio without so many cut outs.

Hi all i am also trying to do this. I have createt The shortcut just fine but if i follow the shortcut and choose from the dropdown menu It doesnt remember the settings when i quit... And there is no save/apply button. Or is there something i am missing here?? please if someone can help i will be wery happy

Well, for me I just choose WCDMA and wait for a few seconds untill the 3G signal appears then just hit the back button and thats it. Its forced to use 3G only. No need to push any save buttons.

Confirmed not working here either, select wcdma, come out of menu, go back in, and it's already changed it back to gsm/cdma auto. Seems it refuses to apply settings.

Working good using any cut. Thanks!

wtf
this toatly messed up my phone, i swhiched to wcdma preferd and my data speeds have competly crashed, when i go to change it it now says unknown and dosent save my choice

in my case it does apply settings, soft of. Switching GSM only ---> WCDMA only, all my bars immediately appear and I the phone starts getting a signal. The settings remain there if I check repeatedly. However the setting do not survive the the phone reboot. It goes back to "GSM only" mode and I have no reception. I can help it changing the settings again, but it is quite annoying.
Started happening to my phone after I travelled with it to east europe. Had some troubles there making it work with their sim-card and had to call the provider. They must have fixed something in my phone remotely. Now I'm back to asia and this is kind of **** is happening.

WCDMA Only Resets To WCDMA Preferred

I use my Nexus set at "WCDMA Only", which best suits the network I'm on.
However every now and again it switches itself back to the default "WCDMA Preferred", which I don't want. I usually find out when the network access hangs, and I then go to check the preferred network type.
I think that perhaps this might be caused by a battery pull?
Anyhow is there any way of preventing this? I'm on stock unrooted 2.2 FRF91, and would prefer not to root.
Is this a bug/feature, or something I'm doing wrong?

Don't think it is a bug because it happens to me sometimes on both my rooted phones.

Any idea what might cause it to happen? Is it after a battery pull? Any other suspicions?
Will keep a closer eye on it now myself to see if I can pinpoint when/how it happens.

It happens when I wipe the data to flashing a new rom. I adjust the settings to wcdma so the sign-in goes quicker. I have to set the wcdma again even after the first time I set it. I haven't notice it after a battery pull in my case. I will try to pay more attention when I happens again.

I also stuck with this mess. Im on ICS euphoria 2.1 and whenever I type in the secret code to turn from WCDMA prefered to WCDMA only, press back, and it automatically changes back to WCDMA prefered. What the hell?
Any ideas?

wCDMA Milestone (mod)

Doing this will boost call QUALITY & response time between the tower and your phone. It also seems to cut alot of the background noises as well.
1. open dialer
2. *#*#4636#*#*
3. change GSM Auto (prl) to wCDMA preferred.
4. click Enable QXDM SD Log
5. SMSC: -refresh, then long hold update.
6. Scroll to top, run ping test...
7. Once done, hit HOME.... NOT BACK!
if you run into any issues, swap back to GSM-Auto (prl) then update your SMSC number again. By default it loads as GSM-Auto, so if you reboot, you will have to swap it again.
-=-=-=-=-=-
Ive been running like this for around 10 days now and & definitely notice a good gain in call quality, not only in response time, but clarity as well. I don't get any background static and outside wind/other noise seems to drop as well also.
-Leave me feedback and let me know what you think if you try it.

I dont really feel any difference . ill tell you in a couple days
also there must be a way to set this on boot or make this persistant , I noticed if you go back in that menu and use back to exit it will also revert changes to default ...

btw got my first compliment today someone said my phone sounded louder then usual 9normally its the otherway aroud ppl say its not loud enough ...

Did it and the network xhanged from GPRS to HSPA will test it and report here

Im sure ill get it at some point or another.. so here is it...
WHAT IS wCDMA... and why is it better than GSM?
-=-=-=-=-=-=-=-
wCDMA (Wideband Code-Division Multiple Access), an ITU standard derived from Code-Division Multiple Access (CDMA), is officially known as IMT-2000 direct spread. wCDMA is a third-generation (3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market.
wCDMA can support mobile/portable voice, images, data, and video communications at up to 2 Mbps (local area access) or 384 Kbps (wide area access). The input signals are digitized and transmitted in coded, spread-spectrum mode over a broad range of frequencies. A 5 MHz-wide carrier is used, compared with 200 KHz-wide carrier for narrowband CDMA.
Summary:
1.WCDMA is a 3G technology while GSM is a 2G technology
2.GSM is slowly being phased out in favor of CDMA
3.GSM is still more widespread than CDMA
4.WCDMA and GSM uses different frequency bands
5.WCDMA offers much faster data speeds than GSM
6.WCDMA would soon replace GSM

It's stated in this thread that it's non-dangerous as you can just reboot the phone / change it back. I'll just pop in here with a word of caution: I couldn't.
I have received a significant increase in speed and response time on my data connection since performing this change. I've received significant performance/quality on my conversations over the phone. I can still receive SMS's, however I can no longer send any...
When I attempt to change it back it's already on "GSM auto (PRL)", and I can no longer get the "Enable QXDM SD Log" button when changing to "WCDMA preferred".
I've attempted to change back by ignoring the step that included the "Enable QXDM SD Log" button, but to no avail.
I've attempted to re-flash GOTs 2.2.1 as that should include the most partitions of any flashable ROM, and I had hoped it re-wrote the radio. Apparently it did not.
I basically have a looong night of debugging ahead of me Such is the nature of modding.
[edit 1]
My phone is a UK Milestone, one of the first models. I am not sure of the technical term for the model.
[edit 2]
Solved it.. The SMSC number was set to 5p41450522.
After some time I found the SMSC (SMS center - responsible for sending SMS on the network) number from my provider. For TDC in Denmark it's +4540390999.
Pressed UPDATE and home button.
NOTE: For non-english phones the menu is translated, and as such the 2 buttons next to the SMSC field may be named the same. The left most button is UPDATE, the right most button is REFRESH. Some languages tend to translate those two words to the same.

The default setting, GSM auto (PRL), will switch to wCDMA when there's a load on the network connection. That is, with a call, a download, or something similar, the phone will accomplish exactly what's been done manually.
The difference is that with this setting, the phone will almost always prefer 3G, meaning you won't have the benefit of using the less power-consuming connection when there's very little load. There has to be almost no traffic for it to step down to 2G.
It won't affect call quality, and if it does, I'm going to go out and state that it's simply a placebo effect. Regardless of which setting you choose, call quality will be the same, as both will have the phone switch to 3G during a call anyways.
One thing you may notice, though. With it set to WCDMA preferred, you may notice a less reliable data connection, and perhaps some dropped calls if you're not in an area with good 3G coverage. GSM auto will prefer 2G network when reception is low, helping to ensure you stay connected.

This is not an issue to me, because ATT is the dominant force here in the south KC metro area, I always have solid signal!

Tag, I did this to see if it fixes my SMS problem.

Thanks to your "wonderful mod" sending SMS didnt work anymore. Make sure you put in the correct SMSC number of your SMS Service Center!

I can no longer send any txt messages after applying this mod, I did a factory wipe and still can't. Any way to revert this?
Took me a while to find the telus SMSC number: +16475800172

here are two that I found:

sorry to any issues you may have recieved whole doing this... but as always, full nandroid back- ups should be done before adding a new mod. yeah I realize I said there was no harm if this didn't work out, so I'm sorry for that.
Anyways just google for "(your carrier) SMSC address" then correct it if you are having issues.

[Q] How to save the "Network-type" in 4636 hidden menu

Hi,
I own a LG Optimus 2x (P990) running on stock GB with 0725 baseband. One major problem I'm facing with it is it keeps losing the signal completely. After researching online, I found out about the 4636 hidden menu (*#*#4636#*#*) and then changing the network type to GSM auto (PRL). This helped a little. However, the settings dont "stick". After few days, or sometimes, a couple of hours, they go back to WCDMA preferred which causes a complete loss of connectivity for me. How do I save these settings? I dont really use 3G as its not feasible in my region yet. Can someone please suggest something?

Why didn't you just change it at the settings menu under wireless & network? You can set to 'only use 2g network'.

I've tried that before going into the hidden menu. Same thing happens. After sometime, it kinda forgets that its supposed to use GSM and reverts to WCDMA

Happens to me too, i am on temasek's Kang, although it happens randomly and isnt that frequent in my phone so i dont worry bout it much.

Even its random for me. But when it happens, I end up missing calls and texts coz of it. Its soo irritating when the phone is unable to perform its basic functions correctly. I really dont understand why does the device revert back to WCDMA when i'm telling it to use GSM

Turn OFF and then ON phone.
Set to 2G only and save
Turn phone OFF/ON

I was just fighting against the opposite, I want it to be on WCDMA only but the config was resetting every time I restarted the phone or causing signal loss. A few minutes ago I matched the RIL with the baseband even with recommendation and it just worked!

Sprint htc one Cellnfo acts funky in 4636 phone info menu

I have a sprint htc one and in the *#*#4636#*#* menu my cellnfo section acts whacky the paragraph under cellnfo pops open and closed over and over continuously non stop when looking at the phone info screen.
I have had this happen for some time now and I thought updated to 4.3 firmware would fix it but it has not.
Now my phone keeps switching network type on me every so often and its not just when I reboot the phone either.
I keep it set on Cdma aupo prl because my phone is flashed to straight talk verizon, but I"am now continuously having to change it back because it keeps switching to Wcdma only on me.
Hopefully someone has an idea of what the problem is please ????

I get this too. I have tried all the settings and none of them keep a lock. I thought it was just me, sorry I have no fix. I think it's from not being in a 4G area. I also think it has to do with the One being a global device. I think they cut some corners and instead of building a CDMA device, they rigged the GSM to work on Sprint. Therefore, CDMA connection is trash. Just my thoughts and opinions though
