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.

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.

Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.

You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.

sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.

3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck

Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..

Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.

[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP

Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?

Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.

Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

AT&T Tab will no longer connect to AT&T data

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?

Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.

Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.

Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.

I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.

Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.

It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?

Yes, I have voice and 3g data by ising a sim from my old android phone.

[Q] UMTS/EDGE Question

I have a problem with my Galaxy Mini. Correct me if I'm wrong, but there is only ONE version of the Galaxy Mini just different firmware, correct? Here's my problem, my phone is stuck on EDGE when its supposed to be on UMTS.. My GF and I both have the same phone, when I put my SIM in her phone I automatically get "H" and I rarely see "3G" (which is good). But when I put the SIM in my phone I ONLY get EDGE "E". Hers is from my countrys carrier and I got mine locally from a retailer unlocked (European Version). This is why I'm confused, if both phones are the same specs and everything why cant I get 3G/UMTS? I later found out we had different firmwares so I flashed mine with the same firmware as hers and still have the same problem. Could it be that I need to flash my Phone Modem with another one? (Idk..) All answers appreciated, Im desperate

Check if you don't have "Use only 2G networks" ticked.

Under mobile network connection there exist an option to only use 2g connections.
Take a look at. If the box is checked then unchecked it to use umts connections.
By the way. H connection is better than 3G.

I'd also like the point out that I'm computer savvy, I dont have "2G Network Only" checked

Maybe you can try to enter *#*#4636#*#* in the phone. You will get to Testing menu, choose Phone Information and then scroll down, there's an option like 'set preferred network' down there and you can choose WCDMA Only. Hope it helps...
