I've had this problem more than once since I bought the NS. Didn't bother changing the APNs as it was working before.
All I did was restart my phone and it fixed the problem.

I tried entering My apn but nothing works

I've got the same problem: no data connection whatsoever, reboot didn't fix it.

Happened to me once, Reflashing radio or backup didnt help... I ended up doing this.
It may help you
From the dialer, type:
*#*#4636#*#*
Select phone information
scroll to the bottom.
change the GSM/CDMA auto (PRL) to WCDMA only.
Reboot (Had to reboot 2x)
Once data was restored I changed the setting back to GSM/CDMA

Help - Cm7 Update - G2x - No APN connection....

Hey Everyone,
Whenever I update to any version of cm7 and flash a new kernel with it I lose APN connectivity... I can't manually connect either. No 2g/4g nothing. Wifi is fine. I've tried multiple versions of cm7, etc. I don't have the same issue with Eagle 1.0.4 and/or Team Whiskey, flashing back to stock, etc. but anytime I try to check out CM7 I can't get it going! I figure it's something simple but does anyone have any ideas so I can try to get some OC going! Lol...
Thanks Everyone...

Sorry I'd more than happily move it. I'm completely new really to posting here obviously but been lurking for a while now. Don't mean to be a complete noob lol

It's already been reported. A mod will move it shortly. Next time post in the Q&A section. This area is for Development only...hence the name.

Try it without the kernel.
- BFL

I've been recently having the same problem.

Not a problem, this was a question concerning development and more or less the roms I'm downloading from this section hence I posted it here... won't happen again.
As for flashing w/out the kernel, I thought you needed another kernel to run cm7 with? I'm trying to overclock basically which I can't do on the stock kernel either.... so I'm not really sure what to do but I'll see if I can flash back to gingerbread, get my data going and flash back to cm7 w/out using any new kernel... have to make sure the rom doesn't autoinstall the new kernel either when you flash the rom

Update the apn settings for t-mobile. You can find them online just by looking them up. Try that.

What works for me is a hard reboot. Hold volume up and power for 8 seconds. Apn should be there when you boot back up (usually). I have this issue with stock and any other kernel

SOLVED!
I had the exact same issue and fixed it by installing the SIM card that came in the GX2 box.
I had been using my Nexus One SIM up to that point. The T-Mobile customer service rep told me that the G2X needed the updated SIM card and that without it, there would be data issues when not on Wi-Fi.
Write the SIM card information down before installing it in the G2X and calling T-Mobile (or whoever is your service provider) b/c they need the serial number in order to properly provision the phone.

Worked like a charm!!! Thank you!!
Simple yet effective lol
Finally up and running on cm7 with no apparent issues to report!

Also I found out that going into settings,into the apn settings,pressing menu then reset to default seem to kick it outta limbo

Great info everyone, thanks!
I'm still working on getting the market up and running on cm7, but otherwise everything is running really clean!

Thread moved to proper forum.

I have the same issue, and only on CM7..
Other Stock roms work OK for 3G
I have 2 sims - one uses regular APN setting (supplied from simcard) the other one is manual
The one that uses default (simcard) apn worked once after first install..
Than doesnt work..
VOL up + power didnt do the trick..
Whenever I put the custom APN simcard, it doesnt apply the settings..
Very weird..

I'm using the SIM out of my G2x box. Maybe it helps a little but it still happens when coming from a reboot, wifi, or airplane mode.
When you go to Mobile Networks, it won't connect to any of the listed networks.
This is already known and discussed, but to put a solution to this thread:
Go into Mobile network.
Let it scan
Select ANY network, it will error
Select Automatic until it reconnects again
Done.
Once it reconnects, you should be able to go into APN settings and see "Simple" and "T-Mobile". Sometimes if you can you select "Simple" then select "Tmobile" again, it speeds things up.
Works EVERY time. Sucks it requires this most of the time but it only takes a second and will stay connected for as long as the phone is turned on.

Hard reset (VolUP+Power) didnt work..
Is it a problem with their firmware?
I require custom APN's on my Network operator -- stock (or eagle blood/team bionics) work great, but CM7 doesnt for some reason..
Cant figure out why..
Even 7.1 RC0

APN's won't stick until you do what I said above. Once you disconnected and reconnect, APN's should pop up. If you created your own APN, it should THEN be displayed.
Even customs APN's won't be displayed until you disconnect/reconnect using the methods above.

I feel like we're missing a step here. There isn't anything to select, unless you go under Network Operators or Access Point Names. APN is blank for me, so i can't select anything, and doing anything under Network operators doesn't work...

[Q] Re-enabling 4G?

So, when I got the phone I wanted to turn 4G off to safe battery. So I went onto the market and downloaded the LTE On/off app and used it accordingly. However, I've changed multiple roms and now that I've re-installed the app and want to enable 4G again there is no option for it at all. LTE is not mentioned in any of the setting options. How can I enable 4G again or get the options to show?

What ROM you running? Had the same issue running Liquid.
Try fixing permissions?

Wireless settings, mobile networks, select network, cdma/auto or LTE. If that isn't there I don't know.

You shouldn't need the LTE on/off App
You can just go to the wireless and network settings and enable it there and you should see LTE and CDMA Auto select it and it should give you back 4G, unless of course it is down. Good luck.
Also try and uninstall the LTE on/off and re install might help also.

If for some reason, it's not accessible in mobile networks as mentioned above (it depends on the ROM you are using), it might be in the notifications > quick settings or you can dial *#*#4636#*#* on the phone and it will bring up those settings.

I'm running Liquid.
And it's not showing up in phone information, wireless settings or anything.

IIRC, not a setting in Liquids ROM. Above 4636 method works, 4G/LTE shows up as unknown. Be advised, last time I switched to 3G and tried switching back to 4G it would not connect, stayed on 3G. Had to reload a different rom and re-aquire 4G. Oh well, I just leave it on 4g. Btw, also running Liquid GB.
Doesn't really answer your question, more of a heads up.
Good luck

On Liquid GB 3.2
I am running Liquid GB 3.2 and here is how I was able to get my 4g back up and running:
Settings- Wireless and Networks-Mobile Networks- Network Mode- I set mine to CDMA+LTE/EvDo auto
I have played around with the different setting in the pop up menu after you hit Network Mode and the CDMA+LTE/EvDo auto seems to work the best for me.
Good luck and let me know if that helps solve the issue.

[Q] HSPA data issue, Help!

Okay so here's what's happened.
My phone is the LG-925g from Rogers, and it's unlocked to work with Koodo. It WAS working just fine.
Sometime around my update to V20c (I don't know exactly when, so I can't say forsure it's the update) data stopped working properly on HSPA. It didn't entirely stop working, just sustained connections.
Let me explain.
On WIFI EVERYTHING works.
On 3G I can browse, check e-mails etc... but I can't download anything. Market I can browse, but not download. Youtube works in the browser, but not the youtube app. Shazam doesn't work. Facebook updates work in the browser, but not the Social+ widget. Weather updates fail.
I can browse and check e-mail and that's about it.
so data IS working, just not properly.
Here's what I've tried....
-Formatting NV partition
-Formatting Cache Partition
-Formatting internal SD Card
-Complete Phone Reset
-Took my phone to a Rogers store, hooked it up to the rogers cell network on a store-sim and it worked great
-Took my sim card to a koodo store, stuck it in a demo android phone, worked great.
- Factory Reset of phone
- (phone was not rooted at time of problem) rooted to install and use networking tools
-went into hidden menu 3845#*925#
-went into Other Hidden Menu: *#*#4636#*#*
-ran every test in hidden menu and looked for settings that may affect this
-Installed APN Remover to remove all APN's except Koodo
-Verified (with a koodo rep) every APN setting and even tried removing some or messing around with them
I'm about to downgrade and re-upgrade my phone to see if that works. Any chance that may fix it? any other possible solutions? I'll even take crazy solutions at this point because netstats pings, etc etc are not showing me anything, I just get a lot of Syn_sent connections without ACK's.
HELP! (And sorry for the wall of text)

have you tried setting up your APNs?

APN's
Yeah, I tried setting and resetting them a few times, even with a rep from the cell company.
I'm losing my mind!
Thanks anyways though!

Im using 21d. Seems to have somewhat similar problem. Getting unstable connections.
My problem:
phone kept switching from H to 3G to G and H again. Speedtest app revealed very low and inconsistent speeds..Reception bar also kept changing.
Phone was previously froyo. Im not sure if it's because of gingerbread baseband. I have some suspicions on that.

I agree. I think it's a GB thing. I'm on v21a, and I have the issue where upload arrow keep blinking, and I get the H -> 3G-> H.
EDIT:
I'm having this on v10d too

Data drops since new update

My Verizon Galaxy S3 has been dropping its data connection since the update a few days ago. Sometimes it's been an hour or more before it's restored, other times it drops to 3G briefly before returning to 4G. I'm also noticing reduced battery life, which is almost certainly caused by the data problem.
The internet is abuzz with others reporting the same problems and tech support tells me that they're aware of the issue and are waiting for Samsung to put out a fix.

I seemed to have the same problems as you described and doing a sim card pull then battery pull and put back in and the phone will reboot. Then wait 5-10 min and put back in the sim card and then reset phone. When phone reboots change to cdma/lte in the network settings and reboot again.
Data seems to work about as good as previous update. And best part is you don't have to factory reset. I am going to take a wild guess that the lte authentication is having problems with the update and resetting the sim card on the network clears things up. Try this and report back if it works or not.
Almost forgot the new caller id app may have something to do with these data freezes as well. What you do is go into settings, application manager, scroll over to all category and head down to caller name id and click on it. Then clear data, disable and finally hit force stop. You might want to reboot after this but it should stop it from running. It's a pos rip off and you can get a free app that does the same.
**After a couple days testing it appears that this caller id app is the main source of problems. I have ran global and cdma/lte settings and data gets locked up constantly when this app is left to run. If you can't get on 4g at all since update you need to do the following first and foremost. Settings, more settings, mobile networks, access point names and make sure lte-verizon internet is check. I have seen this setting uncheck itself so double check it please.**

Tried and it did nothing for me. 5 minutes after following your directions, my phone dropped data again.
Thanks though.

I'm in the middle of a chat with a Samsung rep and they're system doesn't even show this update being released....lol.

Do settings, about phone, status under signal strength what does that read?

-106 dBm 32 asu
I do have a 4G connection right now.

That is a pretty low signal for 4g lte. I am gonna assume that you had drops prior to this software update but they where a lot more rare?

No, never.

Well there really is only one other thing to do an it's a factory reset. Odds are it won't help since others have tried it and it did nothing for them. Otherwise we get the fun process of waiting multiple months for a fix.

Just wanted to give a heads up. I originally thought you could uninstall the new caller id bloatware but it appears it only uninstalls the icon from the drawer so you still have to go into application manager and disable it because it turns itself back on after uninstalling.

Still on the older version. The LTE signal is marginal where I am. I routinely get between -106 and -112 with 2 bars, and I never lose my 4G signal and the download almost always tests at 8Mbps or greater. At work, I have all but one bar, and my signal is 88.
A signal of -106 does not mean that the phone will lose the 4G signal. I rarely drop until I get to around -118. Though I'm sure that these phones could have a stronger signal than they do, they seem to hold on to a signal pretty well.

I haven't lost my data since disabling the caller ID app.

Yeah it's the same for me. When I realized that turning on wifi that 4g lte would stay on I knew this app was tied into the radio. And being made by verizon I had a funny feeling this would be of the lowest quality.
