Can't edit APNs - G2 Q&A, Help & Troubleshooting

I have flashed Bliss rom and cant get a signal (voice or data) on vs980. (Also tried Resurrection with same results) It starts off with no signal and then after a few minutes says no sim card. I tried to change the APN but it says APN settings are not available for this user. Did a completely clean install. I am not using it on verizon, but a small regional carrier. I had it working on Verizon and then switched to the regional carrier. I had it working great until I did a clean install. While troubleshooting, I flashed a stock firmware rom and can get that one to work once I input the APN, which it lets me do. I tried restarting multiple times and no change. I have look through past posts and have not found an answer.
Any help would be greatly appreciated.

Galaxy S - no signal

After factory data reset phone can't see GSM network and can't register. It says NO SERVICE. SIM card ok. check at another phone. What can be a problem and how to fix it?
Some info below:
fw: 2.1update1
baseband i9000xxjf5
kernel 2.6.29
build ECLAIR.XWJF7
csc i9000serjf2
p code: gt-i9000hkxbri
Have you checked your APN settings?
I can't make even phone call. APN...What to check in particular? wifi and gps are working fine. tried service mode... it says signal strength 0db.
My wifes is the same way it cant lock on a service provider after factory restore only way it works is with a custom rom cant figure it out
Contact your network and enter mobile network settings manually .

flash to custom rom maybe?
it's your APN settings
just google your APN settings... i.e. i'm with Bell mobility... if I google Bell APN I will find the info I need... that data goes into settings>wireless>mobile networks>access point names
hit the menu button and add apn.... bell's examples are here http://androidforums.com/samsung-i7500/87145-bell-mobility-apn.html
they are carrier specific obviously
Hi All,
This happened to me before and I was as frustrated as you and when I was about to give up, I tried one last restoration, but only this time I did it correctly. After that, I restored 5 different versions of Samsung Galaxy S stock ROM back to my Samsung Galaxy S. One of these versions were Chinese, and everything was in Chinese.
Samsung Galaxy S had no signal was because the modem file was missing while you were performing the restoration.
Now, all you have to do is go to this page and follow the instructions to restore the Stock ROM back to your Samsung Galaxy S.
You can try to install a different rom just in case. I had the same problem and i tried to fix it applying different modems but that wouldnt work so i ended flashing cyanogenmod and back to another custom rom and that did the trick.
Even flashing back to the latest official rom for my country and operator.

HELP I broke my LTE

First off I'm using an unlocked S5 on straight talk's LTE network, have been for about 9 months with no problems. I've talked to support twice and they reactivated networks and all that good stuff, and when none of that worked sent me a new sim, which I have just activated and it still didn't fix my problem - so I'm finally bringing my issue here.
Last week I decided to update from phoenix rom oc4 (I think it was oc4) to optimal rom og5 (15-5). Anyway I was hasty in flashing and messed up, so just went back to stock ncg > root > full wipe > flash firmware, rom, kernel, firmware again just to be safe. The rom works fine except I seem to have lost my data connection. The 4G icon still shows, but it's not filled in - as you can see in the screenshots. To make it even more strange, when I check the network and sim card in apps like Advance Signal Status and Sim Manager, I still seem to be getting a connection to 4G but there is just no data flowing. The only error I can see is in phone info, when I run a ping test, I get PingIpAddr: Fail: IP addr not reachable which you can also see in the screenshots. It would appear this is my problem but I don't know where to go from here. I'm going to start flashing different versions of modems, starting with oc4 to see if that helps. Then I'll probably try different roms, but I've flashed other roms trying to fix this and even restored the backup to when it worked and it still didn't fix my problem. Did I wipe my IP address or something maybe? I am in CDMA/LTE mode, and the vzwinternet apn is selected.
For starters try to put the apn settings for your carrier and if not sure call them and ask them to email you the setting
I fixed it, went back to stock ncg instead of ni2 and that worked. Weird.

No texts or calls, but data when running cm roms

Hi, I'm having a very perplexing issue. For the last few months I have been running cm13 on my phone but recently it decided to not revive/send texts or calls but still got 4g and signal. I hadn't updated the rom or anything so that wasn't the fault. Looking at the sim card info in the setting it says it's in service and everything, but says the "cellular network state: Disconnected". I've reflashed to a touchwiz rom and everything worked fine. So far I've tried different cm roms clean and dirty flashing, flashing just the modem on to the cm roms, restoring from old backup before all this, replacing the sim card. For awhile I though it was the APN settings weren't right, but the cm apn settings matched the TouchWiz ones. I've also tried different unbootlocking methods, didn't help. Worked with an unlocked bootloader running touchwiz. My brother has been running the same phone and rom I was and hasn't had any issues. I'm out of ideas on what's causing this right now, hoping some can help.
Had something similar happen. Try changing the APNS till you get a single
Changing preferred networks might help too
