Running CM12.1 2015511-nightly. For some reason my phone says No Service even though I have a sim card. I googled it and I tried *#*#4636#*#* but I cannot enable my cell radio in the Phone Information menu (button dosnt change to "turn off" and I cannot select radio band (only option there is automatic and that gives me a failure message).
I would really like some help here. XT1023.

Hi guys,
I was having a lot of issues with my Verizon Note 2 for a while. No matter which ROM I flashed, the best connection was a less than decent 3G connection. After a lot of fooling around and looking for a fix though, I finally figured it out and now I want to share in case other people are having the same problem.
If you already checked to see that your SIM card works in another 4g phone and vice versa and that didn't tell you anything, try this:
-Go to your dialer
-press *#*#4636#*#*
-in the menu that it brings up, select phone information
-change the preferred network type to the one that applies to you (for me, it is LTE/CDMA auto (PRL) )
-make sure all the options under that network type selector are enabled (it will say turn off radio, turn off IMS, etc on the button)
-toggle the DNS check so it says "allowed"
After you did all this, you should have no connection at all. No bars. Nothing. Reboot your phone at this point and you should have your 4G!!
Hi,
I am wondering if there is a possibility (some tweak/registry change) to set the option (found at Settings-All-Personal-Phone-Network) Network selection to Manual instead of Automatic. Every time I restart the device, the option is set to Automatic. This causes a problem due I live near the boarder and every time I loose domestic signal, the phone connects into the roaming which I did not want.
Thanks in advance.
Would of thought that would be tricky as radio takes time to initialize on boot plus the manual option require manual selection of operator !
Can you not control this by 'Set Networks' settings for networks chosen & unticking ones don't want connect to, I had similar issue with a roaming sim I wanted on specific network & it worked for me.
Thank you for answering, but
1. I can not find a option "Set networks" in (in Settings-Phone-Network) which can be unticked,
2. I need sometimes (by going abroad) also this operator, so I do not want to cut him off complete.
I thought there must be a tweak possibility to start the device with manual network selection. A lot of phones remember the last choice Automatic/Manual after restart...
well it in phone settings > network & right by side of the drop down to select auto or manual network selection 'Set Networks' .
Don't think you will get it to work as smoothly as you would like but worth having a play with this setting if you find it, any network operators unchecked can be rechecked when needed.
You could also try another radio version such as one in my signature ...
My DNA when turn to global mode or LTE/CDMA it become no phone wave
Then I use GMS only and it work
So my fone can't use 3G and now it run on 2G/EDGE 20kb/s very slow
Any one know this problem plz tell me how to fix , THANK ALL :laugh:
you may entering code in phone dialer
*#*#4636#*#*
you enter Testing mode menu
choose Phone information
find "set preferred network type" :
switch from GSM only to WCDMA only (or whatever that contain WCDMA)
after that you may seen that your lost signal and tadaaa... 3G appears.
you must doing this method everytime you restart your DNA.
or you simply download intelli3G from google play and switch as you want.
may this help you
Try to send an SMS and get a can't send error message. Looking at SIM cards in Settings abd the SMS Messages is greyed out. Any ideas?
where are you based ?
i find if the radio band is set to USA the calls and text function are greyed out. leaving only data to work.
only if its set to Europe for me do calls texts and data all work together .
to change the band press on the dial pad *#*#4636#*#*
this will enable engineering settings.
press 'phone information'
top right press the '3 dots'
press 'select radio band'
then choose a band based on your location or play with them see which works best exit and try that.
redo the steps to change again.

My P9000 keeps crashing when I select radio band. I get the error stating "com.android.phone has stopped". Any solutions beyond soft-resetting?
Greetings all, in need of help,
My moto g2 says "error while searching for networks". I dialed *#*#4636#*#* and went into phone information and it says "GSM service: Radio off". I scrolled down and tapped turn on radio but the radio wouldn't turn on, how do i fix this?
what did you do with your phone before this matter happened?
You should take the sim out, enable flight mode, and reboot again, then disable flight mode and insert sim again.
hope this helps, or else there may be some problem with your sim (broken sim? you can take your sim you and check it again with other phones)
