Are there any guides or info on where the phone radio settings are stored in Jellybean 4.2.2 for the Verizon network? I'm thinking somewhere in settings.db?
My main interest is to try to find a setting that will prevent my phone from connecting to any network extender. Any information specific to this setting would be much appreciated.

It seems (or according to a Verizon tech) that Verizon disabled the ability to change APN settings on the Galaxy Tab 1 10.1 Since I use a special application i need a static ip and need to change the APN to WE01.WZWSTATIC however the network does not seem to be able to provision it. And since vzw blocked access to it is there a way to assess the apn settings?? maybe i am not using the correct *# code or i am not typing it in the correct place. Any suggestions would be great.
Interesting however are the new Galaxy Tab 2 that we have that allow access to the APN settings... (sigh)
Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.
so I am having APN issues after upgrading from 2.6.3 to 4.1.2 rooted. no data or mms, phone and txt works great. same provider.
galaxy s2 sch-r760 generic cdma, ACS provider here in alaska. apparently goes through gci?
now this is going to be a book, so grab a tasty beverage.
when i add the APN the mnc and mmc are not correct.
when i change them it discards the APN
i have no sim.
this thread did not help
http://forum.xda-developers.com/showthread.php?t=715788
if i dont change those, it seems to communicate with my network as it fills in the mmsc field. but i get no internet.
if i enable then disable airplane mode it shows the 3g emblem, then it disappears.
I have all the correct APN info from my provider.
I have tried every way of changing the APN-conf.xml file but nothng has worked.
my thinking is that i need to change the default mnc and mmc that appear when i go to add the apn, to the correct values and then i will be able to save it.
however i cannot find that field in the systems. if someone know a trick i havent found in the last week of researching, please help.
could my phone be locked? if so how would i go about unlocking? could upgrading my software have changed my cdma settings??
i am fairly new to messing with android but i have some linux experience and am a quick learner.
Also if there is a custom rom or kernal or binary or what ever the operating system is called that might fix this issue and work on my device please let me know.
if someone does help i will pay a reward to them via pay pal, it wont be much but hey its better than nothing.
I've had an issue crop up every now and then esp if i switch roms. Right now I'm running the nameless 5.0 ROM t0lte on my i605 and sometimes it gets stuck on edge. Here's some help with getting 4g back.
Go to phone dialer and type *#*#4636#*#*
Should take you to a special menu. Click the top selection should be phone info.
Select band as in attached image.
Also go into settings where you change apn and make sure APN info looks like attached files. Then goto network operators and search for.. Try one of the at&t ones.
This should work

****NOOB Question**** I just bought a Sch-I605 from a friend and had it switched from VzW to Straight Talk, ive rooted using ghettoroot method (Super Shotout to the creator of it because it made at least rooting on 442 ND7 easy as pie!) right now i have not done much else to it is there somewhere that can show me the best settings for my phone/ maby also by area/ how would i know what the best settings for me are? if possible can someone point me in the right direction to learn more about what i am looking for ( im not even sure if i am asking the correct questions) id like optimal apn settings and id like to learn how to verify / can i switch from stock VZw settings to another as far as my data profile ?/ where can i find out how to gain unlimited data for my particular model and phone any help would be greatly appreciated .
also the dialer code *#*#4636#*#* did nothing ... the only thing i truly can assume about that part is i did something wrong is there a list of dialer codes?
** also if i am in the wrong forum / area i truly apologize for that where can i ask new to android dev questions id love to learn more not just to do it but also to know why im doing it.
***I TOTALLY apologize for the terrible grammar mistakes self-improving is time consuming***
VZW/ STalk SCH-I605
Virgin Mob Galaxy S2 EPIC4G SPH-D710 X2 rooted
Phone specs out of the way first: GT-i9300, Android 4.3 (via OTA), sim unlocked, not rooted, Baseband i9300UBUGNF1, Kernel 3.0.31-2320216, and the IMEI matches the frame.
So I've got a problem that's very similar to a lot of other people with one or two exceptions. I get the "Mobile Network Not Available" error message and I've tried the suggested fixes except for the Ariza patch and I haven't tried changing my modem. I don't want to jump into either of them yet because I'm not sure my problem is the same as all the others. Here's why:
When I go to set the network manually via Settings > More Networks > Mobile Networks > Network Operators > Wait till your device is searching for operators. Once the search is done it will show a list of Network Operators ... Nope, not mine. Mine shows nothing and goes right back to the menu showing Search Networks and Select Automatically. Tapping Search Networks brings the same result. If I set the Network Mode on the previous menu to GSM only, it takes less time to search, but still returns nothing.
Also, I don't have any bars. Not as in having bad signal, but as in there is no signal strength indicator in the status bar. Instead, I have a circle with a line through it next to the battery level indicator. I can not even make emergency calls with the phone.
I haven't found anyone with this particular problem yet, even though I've been searching all day. Perhaps I'm not searching for the right thing?
I've tried an old ATT sim and an active GivMobile sim, both with the same results. Both sims will register networks on other phones. I started out on 4.1.2 and did the OTA updates to get to 4.3 with no change in symptoms. I did a factory reset before doing the updates. I've never had a custom ROM on the phone. The IMEI doesn't show up as blacklisted on any site I used to check it. I even went as far as replacing the SIM card reader.
Could my antenna be bad? Could I have the wrong modem for the networks I'm trying to get onto? Any opinions or direction would be greatly appreciated.

"(via OTA)" means you have samsung's original ROM?
Reflashing a Samsung-based ROM fixed my IMEI problem some months ago. I don't know if you are on a custom or original ROM, if it is a custom ROM I believe that you already know the process...
Revolution HD 53 is a great custom samsung-based ROM and fixed my issues. Be careful on what you flash, if you're going to do this
Im having the same problem as you had. Just wondering if you found out how to fix your phone. Ive a samsung j3(2016) SM-J320FN. Got a new sim the other day and have been trying everything to get service, restored to factory setting but nothing seems to be working. Like you nothing came up in network operators. Sim works fine in other phones. If anyone can shead some light on the suituation please feel free to reply
