3G????? - Captivate Q&A, Help & Troubleshooting

How does the 3G work on the Captivate??
I put in my networks apn's (MMS and DATA) but it doesnt load a web page or send or recieve an MMS , the 3G icon shows up but doesnt show any activity and also if I delete the DATA apn the 3G icon keeps showing till I reboot the phone.
There is no setting in wireless and network setings to just have 2G on (it had it in the Nexus one).
A 3G toggle also doesnt make any difference.
Any ideas?

dont know. i never had to enter anything in, in order for it to work...it just worked out of the box

did you unlock it and move to another carrier?
The phone shipped with all the settings you need to use the ATT network (Data, and Voice).
Maybe restore the settings back to factory defaults to remove your modifications.

Its an unlocked phone and im using it on vodafone new zealand.

Going to Europe. How to disable data connection and enable wifi only?

I'm going to Germany for a month and do not want to accrue any voice/data charges while I'm there. I plan to use wifi only. What's the best way to disable voice/data, but still use wifi? I also want to make sure that my apps do not try to establish a data connection outside of wifi. One idea I have is to keep the phone in "airplane" mode. But I'm concerned that if I reboot my phone it will kick itself out of airplane mode and start roaming.
Any suggestions?
change the APN settings to point to a non-exsistant server, cell interent wont work but wifi can be on and you can still make/receive calls and SMS if need be
I just got back from Europe, this worked wonders for me.
1. Go to Settings
2. Go to Wireless and Network Settings
3. Go to Mobile Networks
4. Uncheck the Data Roaming Option.
This will prevent your phone from using data while you are roaming.
@dcplaya I am also running on Cin Bell. Works great!
Or get a German SIM, that way you'll have data. If anybody calls you on your US number let them leave a voice mail on Google voice

I have a Nexus One in the UK and have so far taken it to the US, Switzerland, France, NZ and HK. The above definitely works and should be all you need to do. I just had a look at my online balance and can confirm the total on my data charges is £0.00. Note that you can leave this setting disabled the whole time, even when you're in your own country. The phone distinguishes between roaming and non-roaming and acts accordingly.

awesome thx - i came to post this exact question and bam, first thread.

No 3G with Darky's Rom 10.1

I finished installing Darky's 10.1 Extreme Mod onto my Samsung Galaxy S the other day, and since then I have not had any connection to a 3G network.
I live in Australia and my phone carrier is Virgin Mobile running on the Optus Network. Before I flashed over from a Voodoo Lag Fixed stock 2.2, 3G worked fine.
I have checked in the wireless and networks setting to make sure the phone is set to "Use packet data" under mobile networks (Data roaming is turned off), but it makes no difference. I have also turned packet data off and on to make sure. Network Mode is set to GSM/WCDMA (auto mode). During setup for Darky's Rom, I left the Modem to defualt settings, JQ1 or something.
I'm not sure what I have broken but I'd love some help getting 3G back. It is very limiting to what a good smart phone can do.
Thanks
which model of I9000 u have? most likely is a modem problem i installed GB in my GT-I9000T and i had to go back to froyo cuz i didnt had 3G and low network reception...i recommend you to wait for more versions of GB come out if that is your case...
what about your APN settings?
Settings -> Wireless and Network -> Mobile Networks -> Access Point Names

So far as I can tell from the About Phone settings page, it is just a plain GT-I9000 with a Baseband of I9000XXJVO. Though I can't remember what it said before the flash.

There is nothing in the APN Settings. Should there be names?
More Info
I looked up the APN settings for Virgin Mobile Australia and entered them into the phone but when I saved the new APN it didn't appear in the list. Just gone.
I inserted the SIM Card into an unmodified Samsung Galaxy TAB in which I have used this SIM card in the past. Still can't get 3G on the TAB, and there was no settings in the APN section. Could be a problem with the SIM card?
I also used a feature on virgin mobiles website to send the APN settings to the phone but they return an error when trying to send me the settings.

Oddly enough if I just enter in the name of the network and no other details, it does save the APN correctly and works fine again. Sweet
Thanks though all.

Just as I suspected. Those are the 3G settings for your network. If you used Titanium Backup those settings are under [SMS/MMS/APN] Dialer Storage, just restore and reboot your phone and thats it.

Is your pay as you go sim activated?
Can you borrow someone's working sim so you can verify/eliminate things?

good idea
My wife 3G sim works on my tab, going back to the shop as it is the sim car the problem, not the tab
thanks again
Glad it was that and not the precious tab.
Bad Karma
I have finally a Data only 3G simcard, it works on a phone and on a demo galaxy tab in orange shop
but can't get it to work on my tab
can still get internet with the voice and 3G of my wife!!
do I need to flash an orange image ???
No, you need to change a setting.
Google "apn setting orange france broadband"
Go to settings, wireless networks, mobile networks, access point names,
You will have to add the settings you got from google: menu, add new access point.
Fill in the values. Menu, save, reboot.
When the tab starts, go to that apn and select it. Wait a few, then go back one screen, and select your sim card carrier.
You could also go to the demo tab and copy the settings into your tab, or from your wifes phone.
Found out that
IF the wifi is ON then the 3G is OFF
IF the wifi is OFF then the 3G is ON
so working now, end of game
Oops. Good find. Enjoy.

[Q] No H or 3G icon

Hi Guys, I changed my ROM to Froyobread v23b (thanks doixanh!) I noticed that the 3G or H icon is not showing even when I set to "Data enabled"
Does it mean data is not enabled or is it just the icon that is missing..
Any ideas?
Thanks!
Edit: I tried a full wipe already, same thing
I think it is your data that is not enabled. It has happened to my father. The operator network informed him that internet via data was enabled but when he turned on data, the icon was not appearing. The other day they informed him that internet via data was still not enabled and as soon as the operator network enabled it, the icon appeared. So check this...
Thanks Chris!
I checked my network operator and they told me that it is automatically enable after installing the settings they sent me.
I already installed what they sent but apparently it's still not working..
Any other suggestions?
Maybe your phone is using 2G/3G options in networks, which means it automatically selects the network, but in fact I get issue with this, I usually set is manually. Try see this, maybe your phone is trying 2G signal and is not getting answer from provider. You can set a widget to choose between 2G and 3G networks

SM-G781N won't connect to 4G/5G, only works in 3G

hi
i got the phone from korea, the problem is when connecting to 4G the phone would lose internet and calls then lose the network, i get a message saying "failed to register to network (15)" but if i forced the phone to connect to 3G then it works fine. here's what i tried to fix the problem :
turning off the mobile network then turning it on
resetting the network settings
removing NR Whitelist
and none of them fixed the issue. there's a korean menu in the service mode, but i didn't miss with it. i have attached screen shots of the software information and the korean menu in the service menu.
Who provides your service? Have you tried going into network settings and APN and see what that says
If it is a Korean phone and you aren't in Korea and it is locked into the network then you won't be able to get service somewhere else I don't think

im using my local non korean sim card and it's working fine, and im also using my local sim's APN settings, the sim card is not korean and nor are the APN settings.
i want to exhaust all my available options before i go for the format.
