i noticed that my galaxy s 2 has some problems connecting to our 3g network here in taiwan
whenever i put my network setting to auto 3g/wcdma OR only wcdma, my connection keeps getting dropped, itll work for a while then disconnect, then reconnect, and so on
but when i just use "only gsm" it will work but it is very slow
and i was wondering about this because in auto mode, shouldnt it still be able to work since it will just automatically use gsm if wcdma is not enough?
i tried it with several roms and kernels, along with restoring a taiwan csc, but it still shows this problem
i was wondering if this was a common problem, or if it is a problem with my network provider
You can try to Lookup fast dormancy if like. and toggle yours to off or on as needed. Either change the nwk_info as i did or *#9900# for a setting change that does not survive reboot.

i think the problem i have is that the 3g signal here in my area is weak, so when it is in auto mode, it detects a bit of 3g so it doesnt change back to gsm
i read a lot of threads saying that it would be better to put the network setting to gsm auto prl, but when i try to change to this setting, it doesnt stick

lately, i have experienced that, all the new roms, based on cm7X, have gprs connectivity problem for bsnl, india sim cards.
as suggested by a developer (sorry, i forgot the name), i copied the apns-conf.xml file from stock rom to /etc folder in cm7 based rom. but gprs does not connect as it should.
many cm7 based roms do not have the apn settings for bsnl. if an apn is set manually, the story is same... no gprs.
has anyone faced this problem.
because of this, i am restricted to stock roms and could not enjoy fabulous roms developed by all the developers at xda.
thanks.
me also used to have the same problems
if you have 3g connection go to network preference choose auto mode and uncheck use only 2g
now you will be connected to 3g now go and chk use 2g only now mostly you will get data connection
some times going into airplane mode and then back into normal makes it connect
try it and hit thanks if helped

have tried all the permutations and combinations. but connectivity is never for sure like stock rom.
may be a handicap in cm7.
I jus got my brand new NEO V.. It's still unrooted..!
I activated the gprs pack on my carrier i.e Airtel(I live in India)..
But on the 2nd day itself I started experiencing gprs problem..
Even though my gprs is turned on, the "E" signs with those up-down arrows are still appearing, but I can't access the internet after sometime..
The gprs works for sometime but then it stops working as if it gets tired..(Lol!!).. then I've to restart the phone, again turn on gprs, it works for sometime & then freezes..!!!!
All my APNs are correctly set..
Whats the problem and whats the solution for it..??
All help is appreciated..
Can you test your SIM card in another phone? If the same SIM card have problems in a different phoje then th probpem os related to your provider. Then instead of rebooting the phone just swith to airplane mode and then turn off airplane mode, this way the phone will register again. I had similar issue some time ago with a Nokia phone, problem was solved after switching provider.
If you have a very old SIM card it will be a good idea requesting a new one.

Have u tried to simply disable and enable the "Data Enabled" setting on "Settings ---> Wireless & Networks ---> Mobile Networks" ?
This will make your phone to disconnect and reconnect to the GPRS network.
Some network operators could disconnect GPRS connections if there is no network activity during some time. So, check if the network disconnections are after some inactivity periods of time.
Yeah it should be operator problem I know airtel very well...:banghead:
"Switching to AIRPLANE mode" did work..
But still it works for sometime only..! the problem starts again..
I've to keep switching to airplane mode every now n then..!
Is there some other to permanently solve this problem..??:fingers-crossed:

The reason why airplane mode works is because it turns off the GSM radius and other stuff, switching the airplane mode on/off have the same effect as doing a reboot of the device. When you turn airplane mode Off the phone will register in the GSM network again,
It's your carrier's fault

Hey guys my s3 is great except every night when I get home I need to manually go into my mobile network settings and set it to GSM rather than Auto. Reason for this is at home at night my 3G drains my battery immensely. I'm currently running omega 27.9 with root but this also happened on stock.
I'd like to find a way to either set it up by toggle through a widget, or through taster somehow. This is different from just turning off 3G data because the voice component will still search for the 3G network, I want to find a way to actually set voice and data to GSM hopefully automatically (perhaps screen off for 10 minutes?)
I had look at tasker but it could only toggle the data network.
Thanks!

I think HD widgets has a switch widget to toggle between 2G and 3G.
Go to Settings>Mobile Networks>Network Mode>GSM

Hi,
I recently brought a new Sony Xperia Neo L. It is working fine with 3G network but when I am trying to connect to 2G network, it always display unable to connect selected network. I have tried to repair my cell phone using PCC and also done factory reset many times but every times it is only able to connect to the 3G network.
It is able to search the 2G networks but not able to register it. I have checked with 2-3 SIMs. I
Is there any hardware fault ?? Any suggestions would be highly appreciated.

I did that also. Its not working. I set the network mode to GSM only after that I searched for networks. The list of available 2G networks appeared in the list but when I am selecting the 2G network it always displays "selected netw. (****) unavailable".
Any suggestions please ??
worst
i'm on xperia play R800i, and having this issue as well even worst, the battery still drain even when turned off, Should i trash this thing?
Hi all,
I went on vacations, had my phone on airplane mode most of the time. When I came back I turned airplane mode off and now I can only connect to 2g antennas, if I select 3G only I don't get any signal.
When I try to manually search for network operators I get a "Connection unavailable" message
Any idea of what might be going on/how to fix it?

When I select 3g only I can't even configure apns, I don't even get cellular signal.
Don't select 3G only. Use automatic.
Also if you have subscribed to a 3G plan, keep your data connection ON and try a restart.
Even face this often as i travel between two distant places once in a month. First time i did a factory reset. But second time onwards this helped.
