Cant connect to 3G - Galaxy S II General

Hi
Trying today my new phone, I see that I cant connect to 3G networks. I put the sim in it, got signal (with a tiny R up in the bars), can call but I don't get any icon of 3G, so if i dont use wifi I dont have connection.
With my old HD2 android works without problems and I dont need to configure anything, it works out of the box. Here I tried to force GSM mode only instead of auto and connect to a specific network but doesnt work either.
My operator it is a reseller of others so I have marked the checkbox of roaming data and all that stuff, but nothing, it doesn't connect.
Any idea?

Can't connect to GPRS when phone is at full bars

For some reasons, I am having problems connecting to their GPRS server when the connection bars are full(4 bars on the phone). I am using the MDA with cingular service, but I am sure the settings are correct. I've even installed a 8125 rom and used it's settings..
I live in houston, and work a few miles from basicly it's business center, and a few more miles from downtown. Cingular has excelent coverage in my area, all Edge, and G3 is also availiable.
The problem is that I am having no problems with the phone side, but the internet keeps disconnecting or not reading at all? How can this be? Aren't they on the same band? I have to "search for network" in the phone settings to get GPRS to connect, but then the internet will only work for a few minutes and stop working again. The E symbol with the transfer animation is still there, through the animation is not active, meaning the phone is connected right? So why isn't my internet working? I am really at a lost of what to do.,
Is this a problem with mobile internet or is it my phone?
The bars only tell you something about the carrier.
So the carrier is good, it doesn't mean the GPRS/UMTS in working properly.
You still can face problems like no IP-adres, Gateway, DNS etc.
Occasionally I have the same probs in Holland, but then I disconnect/reconnect is sufficient to resolve the problem.
(disconnect by holding the "end call" button for a couple of seconds.
Maybe you have some interference in the neighbourhood?
Try another part of town, if that doesn't help, visit a service center and see if they have a device that can connect normally.
Or maybe you know somebody with a working Universal to test at your place?
If there was an interferencem would it only affect certain carriers or all GSM carriers?
Also, the holding the end call button doesn't seem to work in disconnecting and reconnecting?

Automatic wifi

Hey all,
Done some searching but cant find a clear and striaght forward answer.
Bascially, on my old HTC Dream (Android) wifi would always be searching for a wifi to connect to (and if it found a network, it would tell me). if it was a network it had acess to, then it would automatically connect.
Otherwise, it would just use my contract internet.
So I was wondering, on the HD2, you always have to manually turn wifi on. Then say I leave the house, manually turn it off for it to connect to the contract internet.
Pretty small thing - but it gets annoying after a while.
Is there a way (reg edit or app) to make wifi do the same as the android did?
Thanks!
Bump.
I am interested in this too. I am trying to assemble a Mortscript to do it.
would be so helpfull.
I have my home network, Uni network and girlfriends that I can connect to. Now having to manually connect each time, and then disconnect from wifi when I leave is pretty annoying

This must be a rom issue. What ROM are you using?
My HD2 Wifi will connect automatically to networks I have connected it to before, it will notifiy me of available wifi, it will use cell data when wifi is not connected. Works to me the same as how you described your HTC Dream.
Just the stock one that comes with the phone.
to make my point slightly clearer...
I am at home with my Wifi turned on and connected.
I leave my house and go outside of the wifi range.
My phone still has the wifi icon at the top, but it wont be connected.
Therefore I have to turn wifi off to let it connect to my contract internet.
Maybe Wefi will solve that problem?
On Symbian worked very well.

I shall look into this, cant belive others dont get annoyed at it tbh
I'd like a solution to this too. I have found it annoying since settings my HD2. I haven't had any success with the solutions suggested in the forum to date.
actually guys.. there is another thing.. how about a cab that would force HD2 to open WIFI automtically to update weather/facebook..etc... whenever the any apps needs updating, then shutting the WIFI automatically off instead of trying to connect to 3g. you guys think its possible?
Mine always lets me know when I can connect to wifi.
Guys theirs does too. You dont get what they want.
When wifi is turned on it will search and connect only to wifi. It will not connect to wireless network of provider. So they want a program that would turn wifi off (which would let HD2 to connect to EDGE and 3G) if there was no place to connect to. And it would turn wifi connection back on (dissable 3G and EDGE) when there would be a wifi network to connect into. You get it now? It would neeed quite sophisticated program to switch betwen those two modes.
I dont use Providers network (3G, EDGE) but would like program that would check for avaible WIFI networks that I have access to and Connect to them to get updates (it would check for example every 10min) and connect to it only to get updates and SYNCH. then disconect and wait cca 4hours to start looking for wifis in 10min intervals. Would be nice =)

Then it must depend on the ROM version, but for me it works exactly how he wants, and always has. I never turn Wifi off. If I'm at home within my wifi range and load a webpage, it loads it through wifi. If I walk away, wifi connection gets lost, and I press a link, it will load it with the data connection straight away. If I walk back home or to another place where a known wifi is present, wifi reconnects by itself.

[Q] GPRS connection doesn't work...

Hello everyone
I am a Chinese user. I hope you can understand my English...
Recently I have exchanged my phone with my father's Nexus S.
When I get my Omnia7 back I find that my phone cannot use GPRS connection but only WiFi...
I can turn on the data connection and the top of the display appears "E"
but no app can access data connection, I tried to turn on internet sharing but it displayed "There's no celluar data connection to share right now."
I have tried a lot of methods to fix it...
eg:
1.run Samsung Tools, check on ADC, then reboot, it doesn't work
2.run Network Profile, select Telekom.de ,then select CMCC(my mobile service provider) back , reboot, it doesn't work
3. call ##634#, *#9908# , select Suwon 2G Test Bed and save, reboot, it doesn't work.
4. call ##634#, *#9920# , it displayed all the internet settings, every line is correctly set.
5. add APN in celluar settings, reboot, and it doesn't work.
6. I called CMCC support and had my GPRS service reset, then reboot my phone, it doesn't work.
7. I tried other's SIM cards(GSM) but the same problem. I have no 3G SIM card so I don't know what will happen when I use 3G connection...
8. I put my SIM card into Nexus S, and turn on data connection, it seems that nothing is unusual... every app goes well with GPRS connection...
My Omnia 7 was very hot and in reboot loop several days ago. I put it outside the window to cool it down.
I wonder if GPRS module is burned when it comes hot and into reboot loop?
Try the Samsung network profile app, select some other provider, then yours. works for me. Might be worth a try

Thanks for your reply.
I've tried this but it doesn't work...
I think there may be some problems in GPRS module...
Thanks anyway...

Problem with Mobile Internet Connection

Hey forum,
i go away from home and i have no more wifi connection.
Then i suddenly get a connection to mobile internet (EPlus) first.
As i am in an area without a connection and i come back to EPlus, i can use my phone for telephone and SMS but i get no internet connection automatically.
I must use the airplane-mode to totally logoff and 5 sec later go out of airplane-mode. In this way i get the internet connection back.
My wife has the same problem with Incredible S and GingerSense 1.3.
Is this maybe a problem of EPlus? Or is there anyone with tve same problem and another provider?
Andreas
Perhaps it's your wifi giviing you problems, going bad.
Sent from a dream.
If the signal of your provider (in this case Eplus) is weak, it might not find it right away.
Also, try going into Settings>Wireless settings then under Network mode, check if it says GSM/WCDMA
This setting will try to connect to 2G or 3G whichever has the strongest signal, however if both are available, 3G will be selected.

[Q] Roaming problems (troubles on business trip)

While everything is working perfect "at home" .. but I had quite some problems on my trip to Amsterdam .. I will try to summarize:
- I had to manually connect to my company's wifi even though the access point should be "known" to the phone. I have no Idea why since at home it simply connects to my wifi. Formerly this was not a problem - the phone connected automatically. Could have something to do with 4.3? Happened while phone was in Airplane mode (wifi manually set to on) and while phone was in roaming mode.
- When I quit airplane mode I see a stop sign - I don't get prompted to enter the sim pin. So I have to reboot the phone to get gsm working i.e. see the signal indicator.
- In roaming mode not every network operator worked. The phone e.g. saw Vodafone NL but the network wasn't available for a connection. T-Mobile worked.
- I was not able to make a data connection over any Roaming Network. I assume this is for the reason that I had no APN for that provider. Shouldn't the phone receive the correct APN "over the air" ? Or is Omega lacking an accesspoint list that works for roaming? This is puzzling me.
Any help is much appreciated. Who can shed some light?
