When my phone connect a 3G network, it seems on roaming (R symbol) and it disconnect from internet. But actually it's not in roaming. My rom is Runnymede AIO 2.5 (snq kernel). What can I do?
what do you mean with "actually"? Either you are in a different country (roaming) or not. Check if you configured APN settings correctly.
I'm not in different country. There is no problem with any kernel except snq. APN settings are same as before...
Happens this only with 3G or also with 2G network?

Only with 3G (WCDMA) networks...

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.
Hello folks!
okay, the facts are: Im in very good 3g reception zone, MIUI 1.6.6 with default kernel, .08 radio, data on, wifi off.
Problem is poor battery life when 3G is enabled. Also, when using mobile data the H icon appears and data moves in and out, but sometimes the H icon just disappears and i get network error? I've tried numerous radio/kernel/rom combinations.
When i put airplanemode on, the battery consumption is constant 2mA (currentwidget). With 2G networks only, its 3-6mA. When 3G enabled, mostly the consumption is 20-40mA and sometimes like 10 times in day with minute interval of refreshing i get 8mA readigs. Any app to check if there is some syncing going on? I use only beautyful widgets weather widget, which updates itself hourly. And the normal contacts and calendar sync on. Fellow MIUI users have much lower consumption, a mate of mine gets 2-4mA when 3g enabled.
3g mobile network is one the battery killers. The h icon stands for hsdpa. This the fastest network but the network coverage is not that good yet (except for big cities). Switch network to 2g network (mobile off). If you really need mobile network, switch on 3g. Otherwise stay with 2g. There's imho no sense in using 3g without needing/using mobile network.

I tried using BatteryFu and APNdroid to get rid of my 3G while screen off. But that combination didnt work so well, sometimes it didnt disable my 3g and sometimes it wouldnt reconnect to 3G when unlocked. Any good programs to manage this?
I also wonder, I never cant download anything when 3G icon is appearing in statusbar. Its normally 3G but when I want to use the internet, it changes to H. Why cant I use the 3G network then? Im also having problems when the H goes to 3G the internet connection is lost. For example in market i get network error. The H wont stay there if there is no traffic for few secs.
Configured apn correctly? If you are not sure, do it again. Furthermore, you could try these settings for mobile network:
Uncheck data enabled and set network to 2g/gsm (depending on what you have). When you need mobile network, switch to "wcmda + gsm (automatically)" (name could be a litte different, translated it from germany) and check data enabled. I do it so and it's working fine.

Okay didnt understand very well what u ment by the last part of ur message
APN configured correctly? I have carrier default APN settings which have been working just fine for a year. If u ment APNdroid i didnt do much configuring with it. Gotta give it another try.
Last idea: flash latest radio.
No warranty for any damage.
I was wondering how one switches from 4g to 3g(which i think people here call edge) to save battery.
I dont see it anywhere in settings so i wasnt sure what people did..
Thanks!
I think you mean 3g to 2g. This phone does not have "4g". It's just 3g with higher throughput.
I'm not sure if you can on the stock rom without a USSD code. But on custom roms it's:
Settings
Wireless and network
Mobile networks
Network mode
GSM only.
Unfortunately apps like llama/JuiceDefender can't do it automatically when you're on WiFi or not using data because Google "blocked" it. I think CM7 allows apps to control 2g/3g toggle though.
I thought if your wifi was on the 4g was turned off.
Also, on stock 2.5.- the system folder for wireless settings has a choice to only use the edge frequency. I don't know for any of the modded roms or the newer stock 2.6.- versions. Hope this helped.
T-Mobile uses 3.5g(which they call it 4g) a more advance 3g speeds so a with a 4g/3g toggle wouldn't do any good unless you wanna go to edge/2g. is not like Verizon where I think you have your Band for 2g/3g and a separate Band for 4g so what the toggle does its just turn off the 4g Band and automatically goes to 3g. but with Tmobile your have your Bands for 1g/2g and another band for 3g/3.5g(fake 4g) so using a toggle you would only be blocking 3g.
In cm7 When i select wcdma only and activate 2g Internet plan... The network directly switches to gsm... In stock rom if u hav 2g data pack and use wcdma network then the icon remains as H(hsdpa) but 2g speed as its a 2g data plan and it remains on 3g network . In cm7 if i do the same the icon shows as E(edge).. Why can't i get 3g network on cm7?

Hello all, I'm hoping somebody will be able to help. I've got a desire HD on 3 UK (I haven't contacted them coz tech support is useless and I don't want them to know I'm on a custom rom), running LordClock's ICS 8.6.1, My data works fine on 3.5g but as soon as phone switches to 3g I get no data at all. I've tried various roms I've Googled for hours and found no solution. I've checked APNs and tried various versions found on web, I've tried changing the WCDMA preferred option in hidden menu, I've cleaned and reseated the sim, and tried turning airplane mode off and on The annoying thing is data has worked on 3g on Ice cold sandwich in the past, I think v7.3. I was wondering if it had anything to do with build prop and have changed and added various lines but with no success. Any advice or suggestions would be greatly appreciated and thanks will be given to anyone who contributes. Thanks.
What do you mean by switching from 3G to 3.5G? There's only a toggle to switch between 2G and Automatic mode (2G/3G) in ICS right? How are you switching between the 2? Also what is this hidden menu where you switch to WCDMA preferred? (Just for my knowledge. I don't know about it). Does it work for you with different ROMs?

Hi sashank, I meant just that when I lose a 3.5g signal and it automatically drops down to a 3g signal I'm not switching it myself, and if u go into the dialer and type *#*#4636#*#* u get a hidden menu called Testing with gives u info bout network or battery, check it out, the WCDMA option is in Phone info.
Hi, I have exactly the same problem. just to clarify, I am on the 3 network too, and when I have H (HSDPA) signal, the internet works..and works well. however as soon as it changes to 3G..the internet doesn't work at all
you should consider flashing other radios
