[Q] After CM11 phone switched from GSM to CDMA? - Nexus 5 Q&A, Help & Troubleshooting

Hello, yesterday I rooted my N5 and installed CM11 stable. After a few hours I started getting no service, so I tried rebooting it.
Nothing, still no service.
Then I thought to myself "F this, I'm going back to stock". Flashed the stock image (ktu84p) and set up my phone.
"searching for service".
I noticed that there's written CDMA in the mobile options and so I turned it off and reinserted SIM. Booted up, "Searching for service". The menu shows no option to select a mobile network. It only states that there are CDMA options.
Later I found out that my "about phone" page states something about MIN number, which wasn't there before.
Sounds like my phone switched to CDMA? How do I revert this? Tried flashing it twice, but no luck. What do I do?

SOLVED
SOLVED! For anybody else with "Searching for service" Nexus 5 problem: (worded it this way for Google search engine)
1. Dial *#*#4636#*#*
2. Go to "Phone information"
3. Scroll down to "Set preferred network type:"
4. Select "LTE/GSM auto (PRL)" or whatever you want

No SIM CARD?

okay odd one, I was using the nav today, going to a restaraunt, and it stuck at the searching for GPS, mid directions
so I force pulled the battery after it froze, as I couldnt shut it down with app killer, or task manager
phone boots up, wifi works, but now it wont see my SIM CARD for some reason
I already factory reset through the menu section
I cant factory reset since I have CWM (using nvflash) installed and power, volume takes me to CWM for some reason
logcat included
and my cell standby has been at 71% all day
I'm having the same problem...
I turned my phone off this morning for a meeting, turned it back on and now the phone doesn't see the SIM. I flashed CWM 3.1.0.1 yesterday, could that be doing it? I'm not sure how it would be...
I noticed that happened to me a few times, I had to reboot the device on one occasion, and on the other I had to get a new sim card, as all my account data was wiped
I never figured out the issue, just go get a new sim card would be my advice
also watch what charger you use, as I tend to think my generic mini adapter may gave fried one or both of my sim cards
T-Mobile Nationwide Network Issues
I've had a similar problem. After calling T-Mobile I found out that they're having network issues and that manually selecting a Network Operator fixes the issues. I was told that if your phone leaves the network or if you disable your GSM/UMTS radio (airplan mode) devices are unable to automatically re-join t-mobile's network.
To join a network manually go to Settings > Wireless & Netowrks > Mobile Networks > Network Operators > Search Networks > Select any Tmobile Network
NOTE: T-Mobile networks will look grayed out but a long press should do it.

[SOLVED]: "Mobile Network Not Available" error

I have had several instances where something I have done to my phone created a situation where I had no phone dialing capability. The error message when attempting to dial is "mobile network not available", and I'd get notice of "searching for network".
Restoring the com.android.phone app did not help with this. Neither did the suggestion seen elsewhere about entering ##72786# into the keypad to reprogram. The past solutions was to do a factory reset/wipe and then a restore of apps...pain in the a**.
Today I was able to work out another solution that has resolved this issue for me (at least this time)!.
1. Download Anycut app from http://www.freewarelovers.com/android/download/temp/1281882094_Any_Cut_1.0.apk, and open.
2. Make a new shortcut to activity named IOTHiddenMenu (the first one of three with the same name in the list)
3 Open this shortcut and select the following: TestMode Menu>UTMS>Debug Screen>Phone Control>Network Control>Band Selection>Automatic, then hit back twice to get to your main screen.
4. Download Phone Info ([email protected]) from Google Play, and open
5. Use Phone Info app to change preferred network type "“LTE/CDMA/EvDo" (click on Device Information and scroll down for first box to select and change).
If this works to solve your same issue, let me know in the thread.
And if it helps...give a thanks.
Lair12, now that I am back in the US, for the first time since using my S3 outside the US, I'm getting the no network error as you describe here...
I've tried the steps you describe here, but I still can't dial out (I do have 4g data).
I was wondering if you might have any other ideas before I start flashing? Any insights would be greatly Appreciated!
I had a similar issue recently where I could receive texts and utilize data but nothing else. Attempting to dial out would lead to the "Mobile Network Not Available."
This problem first occurred after putting a T-mobile sim in the phone. I tried numerous things such as playing with the phone settings in phoneinfo and I even restored the Verizon image which re-rooted my phone but nothing would help.
I decided to place my microsim into my thunderbolt (with an adapter of course). The thunderbolt worked just fine (phone calls, SMS and Data).
I then placed the microsim from the thunderbolt back into the S3 and everything went back to working as normal. Not sure if it will work for anyone else but I figured I would share since I went crazy trying to find a solution that did not require a full factory reset.
Well, just to close the loop, I was never able to restore my voice connection... I ended up having to reset the phone back to stock to get it back...
Oh well, it gave me a reason to try out CM10!

I'm necro-ing this thread since it just happened to me and I found a fix on CM10.1 given the root cause. Also, Anycut no longer exists in the store -- try using "QuickShortcutMaker" instead.
This seems to happen when the radio gets switched off the correct frequency. To get it back (in CM10.1), you have to dial *#*#4636#*#* . As soon as you hit the last *, you will be taken to a "Testing" menu.
Click "Phone information" then make sure your phone number and IMEI look roughly correct. Then press the "Menu" softkey and then "Select radio band". For Verizon CDMA/LTE, this should be set on "Cellular (800-MHz)". Tap it, and the signal indicator in the menu bar should go back to normal. Also make sure the "Preferred network type" is set to "LTE/CDMA auto (PRL)". (This is also where you enable "GSM auto (PRL)" if you want to make it a WorldPhone.)
The other option in here is USA band (GSM-850/PCS-1900/WCDMA-850/WCDMA-PCS-1900), which I presume is for GSM compatibility since "Global" isn't an option in the "Mobile Networks" menu in CM10.1 (without a certain cherrypick).

Interesting, thanks for the follow up!
I'm currently running Paranoid Android, but this my work for that as well. The next time I leave the US for work, (if I see this issue) I'll give it a try..
Doesnt Work for me, BUT EFS Pro Does!

Re-Necromancing Again....
Doesnt work for me. I had to push "call" after entering last star same error- no mobile network... Thought I would give it a try since I hit the wrong option on the screen. I was looking at the LTE options and got distracted... I did however get EFS Pro to Open IOTHiddenMenu. It is like the 2nd or 3rd tab, you will know it when you see it. Now to find out where (IOTHiddenMenu) is hiding on the actual phone. I did find
*#22745927
This shows an option to hide or show the "hidden menu".
I tried enable and a reboot, but no luck. Looks like EFS Pro is My Solution currently.

[Q] Network or SIM card error.

If I flash any custom ROM that is not built on the stock/ota my phone appears to have some problems with the SIM card.
Specifically, if I go into settings->call settings->advanced it gives an error reading "Network or SIM card error." then it kicks me back to call settings, preventing me from making any changes.
This is a problem because I need to change the "my phone number" setting. If I go to settings->about phone->status it shows "unknown" under "my phone number" which in turn causes the phone to not associate my own contact entry with the phone, and it also causes problems for checking voicemail.
Strangely enough, I am still able to make phone calls, sent sms/mms, and connect to mobile data with no problem, so obviously the SIM card is working and is being read by the phone.
I would suspect that it is a problem with the SIM card, but if I flash back to stock, the problem goes away.
Any ideas anyone?

That happens with me also, running cm7 rom. But that`s not really an issue because there are not important settings over there.If you change any settings before the message pops up , settings will be saved after you exit the menu. Nothing to worry about- your phone and sim are fine:good:

[Q] No Service since new battery put on charge

I have galaxy sl, android 2.3.6.
I have bought the new battery and it was working perfectly till I put on recharge. Immediately after I put it for charge, it is showing "No Service" It does not receive any network coverage; simple shows "No Service"
When I choose "WCDMA Only" it gives "Emergency Calls only" and turns to "No Service" when reverted to GSM or Auto mode.
Everything else is working fine.
Any solutions to this?

Possible call fix for Sprint and other devices running P

I'm on Sprint and was never able to make or receive calls regardless of Network settings in the easily accessible options menu after flashing the P Preview.
The following fixed my issue. You can access this menu without downloading an app but I forget how so it's easier to just download the free app https://play.google.com/store/apps/details?id=com.xsquarestudio.forcelte
I had my network mode set to LTE/CDMA when first using this app, and somewhere in the middle I changed it to CDMA but I'm not sure how much that impacted the actual fix.
These were my steps. I'm not responsible for any damage this may cause to your device as I'm not sure if messing with these settings is foolproof or not.
First, opened previously linked app "Force LTE" then under "Set Preferred Network Type" I changed to CDMA only. Enabled/disabled airplane mode. This seemed to do nothing as LTE was still showing in statusbar.
I then chose CDMA auto (PRL), airplane mode on/off, didn't seem to do much either. LTE still showed in statusbar and couldn't make calls. Also "Voice Network Type" showed "Emergency Calls only" inside the app.
I then chose the 3 dot menu and chose "select radio band". I changed that to United States, without resolving problem. Then selected "Cellular 800" and this may have solved the problem, but I continued on and selected PCS, fiddled with some settings in Phones settings menu. Was finally able to receive calls and my signal indicator showed 3G. In app Voice Network Type was listed as 1xRtt. I decided to select radio band once more and chose Class 10.
Calls were still functioning fine. So I went into Main settings menu and changed mobile network from CDMA to LTE/CDMA. LTE kicked in and calls still work!
Again, these settings may only work for Sprint hence the PCS Network option, and I believe Sprint may utilize the 800mhz frequency. The app might show you different options depending on your carrier. I don't know.
Anyway, fully functioning! Woohoo!!
Android P cannot make calls
I found an easier way
1. Remove your sim card from your phone, and turn off phone
2. Insert a different Sim from anywhere and restart the phone.
3. Try using the phone to make calls
4. Turn off the phone and remove the Sim card
5. Insert the main sim card( your original Sim card) and restart your phone
6. After start allow the phone to automatically reconfigure your network
This method worked for me. Hope it helps someone out there
