Mobile Network State: Disconnected - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Recently I update the google play addition rom to the latest and it seemed to have wiped my cellular information. I cannot make calls and send mms. I have followed a few suggestion here on the forums but to no avail. I have tried updating the PRL and Profile but it is stuck on "checking devise status". I would try the dial code but i have no dial. I updated to Sacs since the CM mods didn't have the update profile and prl build into the rom. Is there something else you all could suggest to get my network working. I do have 4g but i believe that is coming form the sim card. Its the mobile network and mms that is stored internally that was wiped. The APNs are there but I can not edit them to even see if that is the issue.
Thanks

Need some help with data connection

Ok,
Here is the rundown...
I've got a Cellcom Mogul running on Sprint, don't ask, its working as far as voice.
I'm trying to get the data connection working although I've been pretty unsuccessful.
I'm running a wm6.5 rom, although I was running a 6.1 rom too and couldn't get it.
I'm rusty with WM since going over to Android and could use some help..
I've installed the update profile/prl cab, neither work. It seems to hang on "The network is updating your PRL" same with the Profile.
I'm assuming I need to update my profile, not sure how to go about it since the Sprint tool doesn't work.
I've changed the user name to [email protected], I'm not sure what to put as a password, I've got it blank now.
In the data settings I have the #777 with no username/password.
If someone could get me all the m ip settings that would be great.
Anyone?
Anyone have any idea how I can get the data to work. It is registered on my account nothing illegal by buddy at sprint got the ESN added for me so I went back to the original and just need help with the data connection.
IOTA fails everytime.... #777 won't connect.... what can I do?
Update profile fails also.
you might try the "restore" for the data connection, then an iota update.
Did you flash a stock sprint rom?

[Q] WiFi but no mobile

Hoping for some knowledgeable assistance here because FreedomPop has been no help. Two issues, probably related:
I have the SPH-720T 0A3 activated with FreedomPop but it only works over WiFi. I can't connect over 3G/LTE.
I get the Sprint Hands Free Activation on bootup and whenever I try to update Profile and PRL.
I'm rooted and have TWRP. I've tried a couple of ROMs, but they had the same behavior, so I reverted back to stock. I tried changing to CDMA mode and that brings up the 3G icon, but still no data access. It boots up with no APN checked and without the FreedomPop APN; I added the FP APN, but it doesn't help and disappears on reboot. I tried changing MDN and MSID to my FP phone number, but that also hasn't helped and they revert back on reboot. Mobile data is on.
I would appreciate any help on figuring out what exactly the problem is and whether I can fix it or if there is something I can go to FreedomPop or Sprint with and tell them what needs to be done. I'm new to all this but don't mind learning or following directions.
Many thanks.

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.

Can't edit APNs

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.
