I have the app LTE OnOff which allows you to set Preferred Network Types. This is the list of options:
0 WCDMA preferred
1 GSM only
2 WCDMA only
3 GSM auto (PRL)
4 CDMA auto (PRL)
5 CDMA only
6 EvDo only
7 GSM/WCDMA, CDMA, and EvDo (PRL)
8 CDMA + LTE/EvDo auto
9 GSM/WCDMA/LTE auto
10 CDMA/EvDo/GSM/WCDMA/LTE auto
11 LTE only
12 LTE,CDMA
I have it set to CDMA + LTE/EvDo auto which allows both 3G and 4G. What often happens is that I will lose 4G and the preferred network will switch itself to something else, like CDMA auto (PRL) and stays on 3G until I switch it back to what it was before.
Any explanation for why this is happening?
Get a new sim card trust me I had the same problem.

I just wanted to report that I finally got a new SIM card, but the problem still occurs when the LTE OnOff app is set to CDMA + LTE/EvDo auto. So I tried the CDMA/EvDo/GSM/WCDMA/LTE auto setting and so far so good. Maybe this setting would have worked with my old SIM card, I don't know.
Some roms use certain radio combos. I ran in to that problem on a few roms

Stop using this app. It wasn't meant to be used with the HTC one. It might even be the cause of your issue since it tries to override the default network preferences.
Stock rooted rom + Stock recovery + Factory reset = No more problem dropping 4G
That will be the only method to fix your corrupt NV radio partitions.
I would also suggest not using that app, as Disconnecktie said.

All it does is make a shortcut to the "RadioInfo" process that is stored in settings. You can reach this by going to dialer and typing *#*#4636#*#* > Phone info. You will see the it there. The app is perfectly safe because it doesn't do much but shortcut to a process that is stock on the phone. Held in the settings.apk
I sense removed the app and just made a shortcut myself. Right now i have mine set to LTE/CDMA auto (PRL) and its bee working great for me. Check to see if you have the option to change it to that also.
see attached photo, sorry for the graininess of the photo. guess XDA has a limit on how big of an upload you can do.
That option does not exist on mine. See my original post where I list all my options
Is this the app you're using? If you are the reason I say to quit using it is because it was made for the thunderbolt years ago. https://play.google.com/store/apps/details?id=net.andirc.lteonfoff
If not maybe try what Santod suggested. This issue happens sometimes when you flash aosp roms and sometimes when you switch the radio to an unsupported mode. I had to do the factory reset using stock recovery once before because I accidentally switched to an unsupported preference.

I understand that it was made for the thunderbolt but the source for this shows all it does is use Google setting apk to find the radio intent:
private void radioInfo(){
ComponentName intentComponent = new ComponentName("com.android.settings", "com.android.settings.RadioInfo");
Intent mainIntent = new Intent("android.intent.action.MAIN");
mainIntent.setComponent(intentComponent);
startActivity(mainIntent);
System.exit(0);
}
anyways not to get off topic, the app is fine.
OP what rom / kernel are you on.

The app hasn't been updated in over three years. I'm pretty sure the ril has changed a lot since then. A factory reset with the stock Rom and recovery in place will fix the issue.

Solution
@legaldeejay
The best solution to your issue is to do as Santod suggested; go back to stock rom, recovery, and a factory reset.
If the problem even then STILL persists, well, nothing beats a good ol' fashioned RUU (caution: wipes media memory).

I am using an Ecliptic ROM. The app I referred to is not really an app, it is just a shortcut as synisterwolf stated. The option I have been using since I enabled it - CDMA/EvDo/GSM/WCDMA/LTE - appears to be working fine, so I am sticking with that.

With the new roms coming out I wanted to see if people have been able to test the gsm/world band functions. I'll be leaving the country in august and want to know if i will have to flash back to stock or if roms are working with gsm/world bands reliably now.
RMK's ROM seems to be working fine for me here in Afghanistan. I successfully called myself from my Nexus S with my AWCC card in, but for some reason calling VM failed. I think that may have been the roaming network though. I will try again today.

It seems that any of the carrier based MOD's work, but the question is does CM7 work? I loved CM7 but went back to the rooted GB RUU to ensure GSM functionality. I am not confident with CM7 nor do I know how to input APN's to get GSM functionality.

APNs are only for GSM Data - calls and text should work without it.
In the sense rom APNS can be accessed by first going to settings-call and making sure you have gsm/umts enabled.
Then settings - wireless and networks - mobile networks - GSM/UMTS options
I assume it's similar in CM7 but I heard only the nightlies have GSM support and haven't heard anything about how well it works.
I should probably just nandroid and try one today - can't decide between Sense and AOSP anyway

Thanks for the instructions. Where do you get the APN at? I need GSM data as well as calls, etc.
i use that RMK ginger ROM & my phone is unlocked. I have a Telefonica SIM card and found that it works just fine down in Mexico when making calls. There's no data associated with the SIM though so haven't tried that out.

I am running the same one, but I love CM7. I am awaiting a full understanding of GSM functionality and how to use it in CM7.
i tried CM7 nightly 31 and 32 and both doesn't have GSM working out of the box, but the rom itself was pretty impressive.
i opted for the "Incredible 2 Gingerbread Sense/less INCREDIBLY Debloated 8/6/11" by truelefty and chose the Senseless rom. GSM works out of the box, you just need to change out of global mode and instead into GSM ONLY (and UMTS if you have it in your area).
here's the original thread: http://forum.xda-developers.com/showthread.php?t=1169991
also, i am using mobifone in Vietnam
i also read that miui can support gsm as well, so i'll try that later this evening. if someone has beat me to the punch, pls lmk
OMFGB and MIUI support GSM.
I think you might have to enter some apns and stuff manually buy that's just cause world mode is a recent feature. I tried MIUI last week and couldn't get it to work. I don't have a sim so I can't try this week.
OMFGB is sick... it is my favorite rom. Of course, if I could change the color of my battery line in MIUI... that would be my number 1.

Most of the roms listed as having gsm work with phone/sms but not data. I have tried most of them at one point or the other and I can only get data reliably with the china ota. I really was hoping to use the virtousy rom but it is cdma only

I can and do use mms all the time. I am on softbank and I had to manually enter in the correct apn settings for the carrier and sim card being used.
I have been busy so I have not been able to test any new roms knowing the correct apn security settings. Maybe later today I can play with the released roms to compile a list of what works.

hello everyone,
I have my GSM galaxy nexus running aokp_maguro_milestone4 , 3.0.8franco kernel and xxkl1 radio baseband. I used to have no problems with my phone at all until I went on vacation to Spain (I live in Germany) in Spain I had signal but ever since I came back my phone has almost (in the time span of 48 hour it had maybe 1 hour of signal) constantly no signal from my mobile provider (BASE). I have tried reflashing the radio ( I had xxkl2 so I reflashed that and then flashed xxkl1), I have also tried turning phone off and on and leaving it 1 night without battery. any help??
thanks
Check your APN settings, if they are correct try to make a new APN profile from scratch.
checked apn and they were OK. made a new apn with values I found online and still no luck? should I maybe just restore everything to default and flash the stock from?

APN settings are only for data. They do not impact signal.
Go to Settings->More->Mobile network settings->Network operators and either select "Select automatically", or pick one from the list.
Just a suggestion but maybe a whole different updated ROM flash might do the trick

Hi guys,
So I am still having this problem, but an interesting thing happened. I decided to stick the sim card of my gf (she uses another carrier which supposedly uses the same infrastructure as my carrier) and I had full coverage. After that I changed the sim again and had coverage on my line, but after a couple of hours of bad coverage it just never found signal again.
So what on earth could possibly be wrong and what can I do to solve this problem?
I would consider a new ROM, but this doesnt seem to be the problem.

Maybe you should contact your carrier and get a new SIM or check if there is any known problems in your area.

key issue: overseas mobile network carrier VS verizon...
I have tried at least 4 or 5 versions of ICS, still don't know how to get mobile data working, the newest version I tried was "(Rom)(Leak) 7.01.605.01 Verizon Vivow Ics Sense 3.6 *8.21.12" , just like AOKP and MIUI, everything else works fine (wifi, camera, video etc) except mobile data. And unlike CM 7.1 7.2 which has android 2.3.*, I can't even see the "APN" or "Preferred networks" option under Networks category.
So I googled a lot of different ways but nothing really worked. I have edited the "build.prop" file, "spns.xml" to edit the operator code from verizon to my own carrier, also tried using 3rd party software to autoset apn, normally these steps would succeed in CM7.* , but no luck in ICS....
Does anybody know how to solve the problem or experience the same here?
I think I read that, starting with ICS, 3rd party apps cannot modify APNs so that is probably part of why you are having trouble. Try downloading APN Settings Shortcut from the the Play Store. Its a widget that is just a shortcut to the APN settings on your phone. That might allow you to make the changes you need. Sorry I can't be of any more help. I have no experience using phones on other networks, I only know as much as I do because of having to fix APNs to get MMS working on certain roms.
did you flash the firmware (radio) update with that leak ROM? I have had no issues with 3g or WIFI on any other roms before the leak, and the issue with that one is easily overcome with a couple toggle flips. Just the noob's first thought.
Also...seems stupid to repeat, but....make sure the back cover is on, all the way.
yeah u right, unless 3 party apn tool has been added to part of the system, i finally got it to work after re-editing the 2 files above and a couple of reboots...

Glad you got it working. That makes sense considering I often have to enter apn settings 2 or more times for them to work.

Hi,
It started yesterday afternoon, I am not getting any 3G/4G signal on my Note 2. I thought it maybe a "Sprint tower down" problem but when I got home my wifes (unrooted) phone had no issues. I've tried turning airplane mode on/off, restarting and pulling the battery. Nothing worked.
Late last night I got 4G back and I thought everything was ok. But this morning it was back to no data.
My Mobile network settings:
Data enabled (checked)
Network mode: CDMA+LTE/EVDO
When I go to Network operators it gives me "error when searching for networks" and Sprint is not on there.
When I press "choose automatically" it just sits there saying "automatic registration.
I'm on ParanoidAndroid version 3.99-RC2
Kernel: 3.0.64-CM-gbc8f4c9
PRL # 55015
Before I flash back to stock does anyone have any ideas?
Thanks,

I was thinking of that. But I wasn't quite sure how to do it on a AOSP rom. It's easy on a touchwiz.
I ended up factory reseting and flashing back to the previous version of the PA rom. It's working for now. Maybe just a bug in RC2?
Thanks for the suggestion.
Not sure how well this works with Rooted phones, but try updating your data profile in Setting>System Update. If that doesn't do it try dialing ##72786# and let it go through SCRTN. Again, not sure what effect this will have on a rooted phone, but it's worth a shot. If all else fails call customer care and have them refresh SPS, GEMALTO, and OMA in that order.

Hmmm, I just tried it on mine, but it didn't work either... I wonder if it's because it's a non TW rom, and maybe the TW roms have it built in by samsung for sprint. I'm getting ready to flash back to a TW rom, I'll report back with details, for science.
Edit: For science. Flashed digiblur, tested SCRTN, it worked. HFA, PRL update, all ok, phone rebooted and works without issue. So, if you are keeping score, SCRTN works in TW roms, but not AOSP, or so it seems.
If you guys can, back up your current AOSP build and flash a stock one click. Current "safe" PRL is 2006 so once you get on you'll probably get that pushed to your device. Bet that will fix your problems. Then simply restore your AOSP backup.
So after rooting and installing latest Cataclysm (Jan 6th update) with ElementalX I get this exclamation mark on my cell signal and wifi.
When that happens, I can use Facebook, Whatsapp, Youtube and I am able to make calls, texts, etc. What I can't do is load any page that isn't a google page on my browser. Also, I can't load anything on my Reddit app that isn't a text thread. Images, videos and anything external in general, won't load.
When I restart my phone, everything works fine. As soon as I lose signal or turn airplane mode on/off, it appears and I can't get rid of it.
I tried:
Resetting my APN settings.
Reinserting my SIM.
Changing preffered network to 2G/3G/LTE.
Resetting network settings.
Flashing ROM again.
Flashing original EFS again.
Wiping cache/dalvik.
I have no idea what to do or what is causing this issue.
Please help.
Go back to stock ROM and see if it happens there, if it does it's a carrier issue if it doesn't it's likely a bug with the ROM/Kernel you are using.
What carrier are you on? Have you check and/or re-verify those APN settings ? Next time this happen, turn on Airplane mode for 15 or 30 seconds, then turn it off again - do you have a decent cellular signal ?
I'm running PureNexus with EX rom and it's fine, solid (and stronger) signal on T-Mobile vs. N5 used by spouse.

If you enabled data and you don't get the LTE sign, then try going into the Hidden menu and setting LTE to automatic. I forgot the hidden code though, can somebody else supply it? Alternatively, you can go inside settings>others>network>apn and check the apn, then go out and change the option to LTE (recommended) or something
