Can you change how the phone switches from 2G/3G - Desire General

I have problems getting a 3G reception at work. My desire displays the H symbol but just doesn't connect to internet at times. If I manually switch to 2G I can connect. It's really slow but better than nothing! I can leave it on 2g all day but as the H signal works intermittently I like to try the 3g signal first before switching back to 2g.
What I would like to know is if there is there a way to change the minimum H signal the phone has to have before it goes down to E. My phone seems to prefer H even if the signal is too low to connect.
Can this be changed?

Yes.
Go to to the secret menu *#*#4636#*#* and select phone information.
Scroll down to the bottom and change
set preferred network type to GSM only.

I think this is a good idea to put through for the already excellent "Toggle2G" app. Thanks for bringing it up

Thanks, didnt know about the secret menu!
Going by the word preferred it sounds like it is what I am looking for but 'GSM only' makes me think it wont switch to 3G.
Does this mean it disables 3G completely? Couldnt I do that just by going into settings and selecting use 2g networks only?
Edit
Just searched GSM only and found this thread http://forum.xda-developers.com/showthread.php?t=688492. A good explanation of each setting, think GSM auto (PRL) is what I am looking for as GSM only is just 2G but I can usually get a 3G signal so I'll give this a try.

3G / HSDPA Selection

recently got my HTC Hero I am with Optus (Australia) all the time when it says 3G at the top of the screen the connection is terrible (speed tests are slow etc) however if that says H i get more bars and super fast connection
if i use just 2G its just plan slowand not usable for VOIP etc
I am wondering is there a command i set to say only use H which i am guessing HSDPA?
Thank you
OzJames
The phone automatically uses the best connection available to it.
If it's not showing H, you're not within range of HSDPA service.
check on the market and download an apps called "any cut".after u install it open it and create a short cut for phone info by tapping on create a shortcut then choose activity then phone info by scrolling down to the options that says phone info.now go back to the short cut created called phone info and open it and scoll down to set preffered network type.the phone has a default settings to wcdma preffered.tap on the pull down menu and choose wcdma only and press on the back key twice to go to the home screen .this keeps your connection on 3g or H but will reduce in areas you cant get 3g or H.WHEN YOU GET THESE CONNECTION PROBLEMS CHANGE IT TO GSM ONLY.hope this helps

I don't understand, what is the purpose of doing this?
Like I said above, the phone will always use the best connection available (unless you set it otherwise in the options). Why set it to WCDMA only?
If you're in range of HSDPA service, the phone will use it.
Maybe I'm missing something, but this makes as much sense to me as asking how you can download more RAM to your computer

actually it would be like setting the computer up that it would only use a fast internet connection, and if it is slow not to use it at all. would be like connection fast -> page loads, connection slow -> page is not loaded at all.
hs(d/u)pa is an extension to the umts standard. if it is not available in the cell you are using there is nothing to do about it. if you have gsm with edge availabe that might even be faster than a bad 3g/umts connection, but that depends on many factors.
Works perfectly thank you
Its much more stable now

You're welcome
Heya, I'm also on Optus in Australia. The problem thatyou have described is actually really common with Optus users. Optus has way too many customers and have overloaded their system. A easy work around for a more stable connection is to change your APN from internet to yesinternet hope this helps.

WCDMA Only on WP7

Is there way to disable 2g/enable 3g only on WP7? I have a T-Mobile HD7 if that makes a difference.
On Android, you can go to the dialer, type in *#*#4636#*#* and it puts you in a menu where you can change it from WCDMA preferred to WCDMA only. I want that same functionality on my HD7 if possible.
I found the answer shortly after posting this. I swear I searched. Well anyway, to let anyone who wants to know, here are the steps:
Go to the phone dialer
Type ##3282#, Call
Tap the ... on the lower right of the screen
Tap Settings
Under "Network Type", select "3G Only"
Going back into the ##3282# menu/settings shows "Automatic" in the "Network Type" box, but it stays on 3G, indefinitely. I'll report back here if that changes.
thanks for the tip, might want to add it to the tips and tricks thread.
Can you set it to 2G only? I live in a low network area and sometimes calls drop out when switching from the weak 3G signal to the strong 2G signal

I know the hd7 has that option under cellular but apparently not all phones have this.
What are the benefits of doing this?
It's already in tips - it's called Field Test

If your phone has a 3G signal but the Edge signal is stronger, it reverts to Edge. You lose calling capabilities when not in a 3G area but if you are never out of range it stays in 3G all the time, as in my case.

I checked tips and could not find it. Search doesn't allow the search "3G" because it is too short and it finds no results for "3G only" and for "WCDMA only". Who would know to look for "Field Test"?
Not me either - I wasn't having a go at you, just saying it was in there
I know. I was commiserating. Sometimes techies aren't clear about what certain functions do. I consider myself a techie of sorts but I'm not a programmer. It was very difficult for me to find. It took 2 days of searching.
When you set the 3G only change, does it stick?
I'm trying it on my Quantum and no matter what I pick, 2G/3G/automatic, nothing happens..
3G lock is nice for me because I have dialup at home, and I can just throw the phone in 3G mode and tether.

[Q] Mobile data is stuck on "G"

I have finally acquired a data plan from my cell provider, and today I set up the APN settings for it. However, whenever I turn off the wifi, I only get the "G" (GPRS) icon in the status bar, with unbelievable slow download/upload speeds.
I just now tried flashing my radio to Radio_12.28e.60.140f_26.04.02.17_M2_SF (Even though I believe I had it before as well), and still I can't get it up to "H" (HSPDA).
I asked a co-worker with a Galaxy S on the same cell provider, and he has HSPDA speed at the same location as I. I also compared his APN settings to mine.
What can cause this error? Should I try flashing a different radio? is the Radio_12.39.60.19_26.06.04.06_M or Radio_12.35d.60.140f_26.06.03.24_M2 better in any way? Are they stable? Is this even the cause of my problem?
Moved to here
Go onto the dialer. Type in *#*#4636#*#* -> Phone information. Scroll down to the bottom and change 'Set preferred network type:' to 'GSM Auto (PRL)'.
Also, this is the wrong section.
This is not the place to post questions.
There is a QA section here: http://forum.xda-developers.com/forumdisplay.php?f=885
Try **#4636#*#* and select GSM auto prl

WCDMA preferred?

How can you set the Defy to WCDMA Preferred? It constantly reverts off of it.

You mean in the INFO menu? I don't believe you can. At least not with the stock ROM. I believe the choice is controlled by the firmware which varies from market to market, I presume.
That's the same as 3G only? Mine has the option under the mobile network settings. I get three choices (this is exactly how it reads): 2G only saves battery, 3G only better performance, and Automatic Default. Hm you should have the same thing.
In my handset, if you go into Settings > Wireless & Networks > Mobile networks, there is an option/drop-down box for Select network.
It gives you a choice between 2G only, 3G only and Automatic which is the default option and the only sensible one IMO.
edit: same as bobbyphoenix it seems.
Selecting 3G only means the phone will not use the 2G network ever, so if you were to end up in an area without 3G signal, you'd be disconnected.
Automatic means the phone will use 3G when available and 2G when it's not. As I said before, it's the only sensible choice.

That doesn't answer the question. There are two settings within the testing menu: wcdma preferred and gsm auto prl. The former tries to hang onto 3G whenever possible, where the latter uses an internal list of networks and it decides when to switch.

Yes it does.
Automatic means the handset will use 3G whenever possible - ie 3G preferred.
No - they are two different things, as I explained. The Defy is using GSM PRL, NOT WCDMA Preferred.

When my phone uses wifi calling with wifi preferred (in the wifi calling menu) the INFO (testing) menu shows "GSM only". This choice will not allow 3G connection (2G, yes). When I turn off wifi, the phone switches to "GSM auto (prl)" and I get 3G. I read on one forum where someone claims they switched to "WCDMA preferred" then did a battery pull and it stuck. Also read that the WCDMA selection depletes battery faster. Hey, don't always believe what you read.

[Q] Control H/3G/E/G switchover threshold

Can anyone explain how the Arc (or is it generic to android) controls the switch between HSPDA / 3G / GSM etc?
I live right on the edge of a HSPDA / GSM reception area, so sitting in the same chair I'm often browsing using "H", and then slowed down to "G" - and vice-versa. Unfortunately, every time it switches it seems (to me) that there is a lag while it establishes a connection again.
Is their any way to configure the ARC to make it attempt to stay with "H" for a bit longer?
Go to Setting - Wireless & networks - Mobile Networks and change the Network Mode into WCDMA
Hope that help you!

Changing from Edge(E) to Hspda(H) doesnt drop the connection but the from H to E does. Also if the H signal is weak, it will change automatically to E. If you are in a building , parking etc you will have à weak H signal since your phone is covered by the walls

thank you both repliers.
It looks like there's no practical alternative to just letting the switch over happen as Sony have programmed it (or moving house).
You can try forcing to use GSM only or WCDMA only instead of GMS / WCDMA preferred.
The setting is under Wireless --> Mobile network settings --> Network Mode.
By forcing it to use WCDMA, the phone doesn't try to switch to GSM even when it has low signal. Good thing here is that, it doesn't try to switch between the two frequently hence battery might be saved and the bad thing about this is that, when you have a week signal, the phone tries to get better signal since it cannot switch to over to another frequency, hence the boosting uses more battery power.
Try it for yourself .

This is not only happening as programming by Sony but more likely by your operator. The operator defines the parameters that decide when they wish your mobile to switch from one network to the other, how weak they will allow the signal to become etc.
You can contact you operator, maybe they will log a case on it and investigate if the radio planning could be changed in your area.
