I know I'm more likely to find my answer posting in the thread for the ROM that I'm using but as a new user apparently I can't post in that forum at all. I know the issue I'm having is common with GE 4.4 ROMs, but after having read through threads for more than one of these ROMs, I seem to be the only one having this specific issue.
I'm using the Dandroid 4.4 GE ROM, though I had this same issue with one on the 9505 dev forum too. Even after flashing the updated modem.bin, I'm unable to get 3G service to work at all, at least not for long. I'm not talking about just data either - if I'm in an area with no LTE reception, and anything other than 2G service is selected, I won't get any signal whatsoever. If LTE is available and selected, it'll work, though my signal doesn't seem to be as strong. If I have the phone scan for mobile networks and actually select T-Mobile, 3G service will work briefly, but after only a few minutes it drops out completely and never comes back.
So did I flash the wrong modem or do something incorrectly somewhere along the line? Anyone else having this issue?
Nevermind, I think I solved my own problem. I guess the modem.bin had never flashed correctly, I reflashed it last night, twice, and it seems to have stuck.

For the past week and a half, I've had internet issues when I'm on 3g. It works fine on wifi. I've switched between ROMs, kernels, modems, etc. I'm currently on Goodness with the MA6 firmware modem AIO and the anthrax kernel. I've tried updating the profile & prl. I have between 2-4 bars of 3g and yet it still gives me the webpage not available sign. I tried clearing the cache/ fixing the permissions. But the internet simply won't work. I'm in Maryland, between Baltimore and Frederick. What could the problem be? Maybe the phone itself is defective or Sprint's network died in my area?
I'd see if they're doing work i that area. I know in areas of Baltimore 4G is there, I believe. You could try using build prop tweaks ect for signal if you wanted.

Misery loves company.
The 2nd post is a thread I started regarding the same problem. The first post is to a thread I thought could help me. I tried some things mentioned in there but none of them worked. Then someone posted in the thread who is having the same problem.
Here's what I've been running into and what I tried. I am on FreeGS3, Anthrax kernel, and recently updated to MA6 when I started having problems. I use a battery saver so my internet connection turns off when my screen is off. I started noticing a week or so ago that when I woke up my phone, the 3g icon would appear but only the up arrow flashed. The download arrow wasn't doing anything. I would toggle it off and on and eventually get it to work. I'm in the Raleigh-Durham area and we are just starting to get LTE. My 4G works whenever I go through 4G areas and my wifi works. I have restored a working backup, wiped my phone, flashed back to stock unrooted, called Sprint (they refreshed my signal and had me do an OTA activation), manually changed my PRL, upgraded to MA6, updated profile (when I could get it work).........and I think that about sums it up. The one thing I've noticed is my phone works flawlessly when the network mode is set to CDMA. At this point I'm clueless. I really don't think it's a phone issue because 3g works on CDMA. It's like when the phone is set to CDMA/LTE and it doesn't have an LTE signal, it doesn't know what to do. That up arrow flashes in such a rhythm that it's like the code is stuck in a loop.
Hello, I am on AT&T on a GSM Galaxy Nexus. This problem has been happening since the the 4.2.1 update to JB and made me root and flash CM just to see if it would solve it (though I initially wanted to because I was curious since this is my first smart-phone).
So the problem is that at work and certain places I get absolutely no data. I can text sms (no mms since no data) and call people just fine but nothing that requires a data connection works since it timeouts. It happens specifically at work. Nobody that has AT&T in my office has problems except me, so I'm ruling that out. Now previous to this I would encounter the problem in very densely populated places like shopping malls or stadiums but I don't think that's the case here.
Here's the other strange kicker: if I switch to "GSM only" instead of "WCDMA Preferred", it works just fine but it's only Edge so it's slow. I have also tried "GSM/CDMA auto (PRL)" to no avail. The only one that works consistently is "GSM only". Once I leave work I have to switch it back again to either of those to to get HSPA+.
I have flashed multiple versions of CM to see if it fixes and since I like the rom so much I haven't gone back to stock. I've done CM10 Stable through M1~M3 and RC1~RC3 to CM10.1 stable and absolutely nothing has fixed it. It is driving me insane because sometimes work is slow and I grow stupidly bored.
Any clues?
Try flashing a Radio. You can find a list in the development forum.

I read somewhere that you should start deleting them or something, but I'm unsure which.
First of all I have done everything to find an answer to my issues, I've looked in a lot of places and searched a lot of different ways.
The last thing iI wanted to do is post here but don't even know how to ASK about my issue.
I have an AT&T i747 running task650 4.2.2 with underwear kernel.
I am using a ST LTE sim.
Even before I got the new LTE sim I had this issue.
My problem is my phone is getting bad network issues when leaving wifi on, but like when I leave my house, where I connectto wifi, it takes forever to get cconnected to a network if I do get connected at all.
Recently my phone is now displaying NO NETWORK even, like when I try to make a call in my house.
And when I leave my house I won't get a network sometimes unless I turn on and then off airplane mode.
I'm sure someone else has had this problem, maybe I'm just searching with wrong verbiage idk..
I don't even know what to call this problem let alone now how to fix.
If someone has an answer that would be cool.
I'm getting really weak LTE and wifi signals.
I can't even use the mobile internet anymore.
When I go to status, it sometimes says Signal Strength is 0 dBm 99 asu. Other times it's -102 or -105db and 38asu.
I don't know the exact numbers, but on stock firmware, I used to get around 4 bars, but now I only get 0 or 1 on stock firmware.
I made a lot of mistakes trying to install Cyanogen mod. I originally started with 4.4.2 after installing it OTA. I was getting errors trying to flash Cyanogen mod and people were saying it had to do with an out of date bootloader. I kinda messed up in differentiating between the a bootloader and a modem and flashed an earlier modem which made my IMEI null and had no signal. I fixed this by flashing this 4.4.2 modem: http://forum.xda-developers.com/showthread.php?p=53627484
Now here's the problem. I didn't check to see if the signal was weak after flashing that. I flashed SlimKat, didn't like it, and then flashed aokp. This is when I finally noticed the signal was weak. I don't know if it started when I flashed aokp, but i doubt it did. I eventually flashed back to 4.4.2 using I747UCUFNE4 Stock Rooted Odex, and it still had a weak signal.
I then tried Cyanogen mod again and it flashed this time, but the signal was still weak. I then looked at the Android Version and it says 4.4.4 and the baseband version is I747UCUFNE4. Is this the problem? Because from what I'm reading, the baseband is meant for 4.4.2. I'm thinking that when I installed Slimkat, it upgraded my device to 4.4.4? But I don't know. Can anyone help me, please?
Okay, I have an update.
I tried using 3G and I'm getting great reception. Full bars and between -91 and -95db.
It seems there's issues when LTE is active.
Wifi is still terrible regardless.
edit:
Seems that when I call and talk when LTE is active, the reception shoots up. Text messages send and receive instantly.
The only problem is the slow LTE and poor wifi.
No idea if this will work for you, but it should be safe to try it.
In the T-Mobile Q&A forums sticky roll up thread is a link to a GPS fix (NV Rebuild). Follow the instructions there. It us primarily to solve GPS issues but I have seen it help with other problems similar to yours. It doesn't always help, but its certainly worth a shot.
Ill post a link to it in a few.

Hi, it's been a while since I posted on the forums. I've had a problem with this for a while now, but never bothered to ask you all. i don't get certain types of signal with the stock rom and aosp roms. For stock, I get 4g data, and I am able to make calls while roaming but not while I am on regular 1x (connects but I can't use it). Also, signal is iffy, sometimes it connects/randomly disconnects. For aosp, I get almost no signal, only roaming. I think that I didn't mess up my efs folder, my imei is still the same as the DEX on the back of my phone. Do you guys know what is wrong or how to fix this? I want to be able to use my phone again...
What modem are you on? Firmware or ROM? I'm using NE2 with rwilco's stock ROM and a GSM sph-l900 with t-mobile... I get 3G and 4G (hsdpa+)... before I use to get lte/3g/1x and I use roam control when I'm in an area where I know I don't have a good signal...
