no 3G after flash - Galaxy Tab Q&A, Help & Troubleshooting

so i got my tablet back up and running, but its not showing any signs of Cellular life
i flashed CWM7 and i have it up and functioning. i have the stock AT&T modem from the [MODEMS] list, should i apply a different one?
i have the APN settings correct, however, i'm not sure why the tab isnt registering on the network?

i just wanted to post a quick update on this.
i did have wrong APN settings :/ i was using a APN for a phone vs just mobile broadband data.

Rogers (Canada) 3G Settings?

I'm having troubles connecting to 3G with my IS. Up until a few days ago I had an HTC Desire Z that was unlocked, and rooted. It worked great on rogers 3G.
I'm lost as what to try. I've accessed the *#*#4636#*#* menu, and tried GSM auto (PRL), and I end up getting 3G but then it drops. The only way I seem to be able to keep the data connection is to set it to GSM only which gives me 2G/edge
anyone know what else I can try?
Thanks
Have you added an APN for Rogers?
http://redboard.rogers.com/2010/put...ccount-and-paid-apps-now-available-in-canada/
It's under Settings > Wireless & Networks > Mobile Networks > Access Point Names
I'm using a Bell Incredible S on Telus after entering the relevant Telus APN settings, and get the HSPA/3G icon.
well I got it working. When I checked the APN, the MMS proxy ip was missing. I did have it all in there correct before though. I guess from the *#*#4636#*#* menu switching settings in there trying to get it up deleted the proxy ip?
Either way, it's working great. Thanks for the reply thedosbox

[Q] No 3G with 2.3.3 Gingerbread?

I've just upgraded from 2.2, and now I can't seem to get 3G working with AT&T. Does anybody have any suggestions? I've tried fiddling with the Settings but nothing seems to work. Help is appreciated, thanks.
In the About Device, the Mobile network type listed is HSDPA, but the Mobile network state is Disconnected.
Have you checked your APN settings? Also what's your baseband version showing in 'About device'?
Please use WCDMA mode
Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN which doesnt work with the Tab Data plan.
Flash the bell modem then set the apn to get data and phone working after flashing stock 2.3.3?

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...

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.

GT-N7000 Gingerbread -> 4.0.4 (UK) = No mobile data [FIXED]

Hi,
I have just updated my Note from stock gingerbread to the official UK ICS 4.04 from here: http://forum.xda-developers.com/showthread.php?t=1424997 using Odin.
The phone is now running XXLRK (kernel and baseband) - it's not rooted at this time.
Everything is working fine except that I have no mobile data connection. Wifi and voice calling is fine though.
The Network Signal App shows that I have an HSDPA (7.2Mbit/s) net type but the data state is 'Disconnected'. I have confirmed that 'Use packet data' is on in the network settings and I have re-entered the (Vodafone Contract) APN settings several times.
I have put the SIM in a spare phone and data works as expected.
Any ideas?
Thanks

have you tried checking data usage under 'Settings'? , usually there's a capped set if your way over the pre-determine data cap on the phone. Try to raise the bar all the way up and see if you can gain data connection again.

I'm not sure if it helps at all(in relevance to the OP's issues), bear in mind apn settings are different in every carriers. Manually configuring doesnt' change anything at all... even worse, your just aggravating more his problem.

Thanks to both of you - the APN settings are confirmed as correct.
The data usage sits solidly at 0. I have disabled the cap, but even with it turned on and set at 5GB (my cap is 1GB but since we're only 7 days into the month there's no way I have exceeded it), it makes no difference.
I have confirmed with Vodafone that everything should work.
I have also tried a couple of previous radio images without success. At the moment I have just pulled the battery and I am waiting an hour or so before firing up the phone again.
If I can't fix this soon I might just revert back to stock Gingerbread, but I get the feeling the fix should be really simple.
FIXED!!
I added a new APN to the list and just duplicated the Vodafone Contract settings that I know work. This new APN setup was identical to the pre-defined one (which I had been editing) - but it works!!!.
Stick that one in the memory bank for possible future use!

No cellular data after TWRP restore

I'm trying to restore a TWRP backup that I made right after unlocking and rooting on stock ROM. But whenever I restore and boot the device, I have no cellular data whatsoever. I'm on T-Mobile and I'm choosing the fast.t-mobile.com APN in Settings (already selected), which obviously worked when I made the backup. Why isn't it working now?
When I restore back to my current custom ROM on the same APN cellular data works fine again. What's going on? The only difference I see is that in Pure Shamu ROM the APN is named T-Mobile US LTE instead of T-Mobile GPRS on stock ROM. But the settings look the same?
Any help is appreciated.
Double check the T-Mobile LTE APN is correct, you need the one with the - in it.
I think it's here. If you are off even one character, no workie. Page down to Network section.
https://support.t-mobile.com/docs/DOC-10361
I had the SAME EXACT issue... and I found how to fix it.
When its not working, Go into data usage settings, overflow menu, cellular networks, then access point names - click on the T-movile GPRS (fast.t-mobile.com) and make sure APN protocol is IPv4 and APN roaming protocol is IPV4 also make sure Bearer is set to LTE.
