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.

On any of my phones including new Pro2 when I have auto set for band, it always connects to GSM instead of 3G band on my network. This seems to be network depended because when in roaming it always connects to 3G when available.
Simple fix would be to leave 3G band only and not auto, but where I live not whole area is covered with 3G signal so I would often be out of reach.
Is there a way to make 3G (where signal is available) preferred band regardless of network preference?
u should have play around with your device more often, or read a lot in the forum, its in the communication settings - phone - change band - choose WCDMA

I don't think you have read my question entirely
I know where to choose band, but I need it to be on AUTO since 3G signal doesn't cover all region where I live.
But at the same time i want it to connect to 3G first if there is 3G for my network. Currently when band is on AUTO and when I turn on the phone it connects to GSM by default rather than 3G.
In case of bad 3G coverage, The phone "Fall's" down in 2G mode by it self. We can't choose with one is prior to the other. It is an hadware (ie in the 3G ship) that is implemeted this choice, because 3G was promoted to respond to 2G saturation. In your case, this is due to a bad 3G covergage or bad 2G signal.
Hope it can help

I was afraid of something like this
Although I'm not sure this is in phone hardware, rather that preference is set by network. For example on my own mobile network even when I'm very close to 3G base station and signal is excellent, when I turn off the phone and turn it on it will choose GSM signal if phone is set to auto. This happens with every phone, not just HTC. And it will never connect to 3G again unless I set it manually in settings.
On other networks and when in roaming when I turn on the phone and have auto set it automatically connects to 3G, and when I loose 3G signal it connects to GSM but once 3G signal is available it automatically reconnects to 3G.
So I think this is actually set by network and not the phone.
I sometimes work at a place that has full edge signal, and 2 lines (stable and good reception) of 3g. All HTC phones always prefer EDGE, if band is set to auto.

oops sorry, my bad...
even in my room here the 3G signal is weak (1 bar), but the phone still prefers 3G (HSPA) and not EDGE, it turns to EDGE when i go to the bathroom , but when i got out, in a couple of minutes it turns back to 3G.
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.
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.
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.
Hello everyone at XDA
I have an Xperia Play r800a (Rogers Canada)
I was looking in the menus and I remember reading somewhere that if I change the Network prefrences I can get better battery life.
So I was wondering out of these options under Settings> Wireless & Networks> Mobile Networks> Network Prefrences
I have these 4 options
GSM/WCDMA (auto mode)
WCDMA only
GSM only
GSM/WCDMA (WCDMA preferred
What settings should I choose to increase battery life? Also I almost never use mobile data since I am always near wifi.
if you dont use data really just use the data toggle to turn it off till you need it(Way way more battery life)
or if your like me and always need a little data present for google voice and and 4g every once in a while when actually using net then Gsm(= 2g and increded battery life over but 4g connection by couple hours) but alot slower than 4g
then just 4g when you need it (3/4g=wcdma)
auto just choses strongest signal no preference
and Wcdma perfed is just that if both signal available it uses wcdma but if not then then gsm
so for you if no data ever hardly and no constant connection needed then
wcdma perfered and a data toggle by ether a theme with notification toggles or the data switch widget or widgetsoid
hope i helped
Do you know which one would have been the default?
So from what I understand GSM only and data off gets me the best battery life?
For my phone GSM/WCDMA (WCDMA preferred) is default option.
And yes, GSM only and data off gives you the best battery.
