Mobile network wont work. - Xperia Z2 Q&A, Help & Troubleshooting

So I installed Cyanogenmod 12.1 Android 5.1.1 to my Sony Xperia Z2, and after installation my phone wont connect to mobile network. Wifi works, and phonecalls work. There is exclamation mark in the signal icon, and when i connect to wifi it disappears. I didnt find any mistakes in APN. Could it be wrong baseband? Or what could it be?

Maybe internet settings are missing ? go to settings>more> internet settings> download settings for Internet and MMS. (I had the same problem but it is working fine now)

Check APN settings under the Wireless & Networking menu.You’ll find that no APN has been set. You’ll need to choose the one for your mobile operator or worse – manually enter the APN settings.After setting the APN you could need to restart your phone

I have dont that, and No help.. Could it be the baseband version problem? Im trying to install stock rom, test it if it then would work..

Call *#*#4636#*#* to enter phone settings or use this app and select Additional Info
Select Phone information
Set prefered network type to CDMA auto (PRL) and wait until your phone connects to 3G
Change prefered network to LTE/GSM/CDMA auto (PRL) maybe this works? If not I am sorry

The exclamatory means that there is no internet access. Ask your service provider for manual internet settings.

Now i have stock rom ranking,and after i installed the internet settings from mobile network settings, mobile data started running. In cyanogenmod i didnt have that option in settings so I think thats why mobile data didnt work on cyanogenmod.. How can i get cyanogenmod mobiledata working, without the option to install network settings?

[Q] Flashing to Pageplus

I'm following the guide http://forum.xda-developers.com/showthread.php?t=1575749 for flashing the evo 3d to page plus from sprint. currently i have the phone rooted with s-off running meanrom. under the instructions it says you need to enter the MSID on the phone and if you don't have it to call your service provider. I called page plus and they say that they can't give me a MSID without the phone being activated on their service. I'm not sure what to do next. Do I give them the new ESN and have the change the service and then will they be able to give me the MSID or is there another method to do this?
Thanks for any help.
Edit: i'm currently on page plus with a old lg 9100 and the phone i'm trying to flash is a sprint phone that has never been activated.
second question: the apn backup and restore app says that APNS cannot be restored or deleted on this device because android 4.0+ does not allow 3rd party apps to write apn settings. what should I do to get this to work. i have the phone rooted with s-off currently running meanrom. should i put a different rom on there?

Have you flashed the page plus prl yet? If so you need to call them and give them your esn number. I believe the msid is for if you want to port your number over first before you call page plus. If you followed the guide to a T up until the apn part. Even though apps won't allow you to write to the apn, its ok because all your gonna do is delete and restore. Put your phone in airplane plane mode. Delete your current apn, click restore apn chose the page plus one. Disable airplane mode and reboot. I hope this helps you.

thanks, for the input. i'm going to try this a little later today.
so just an update for anyone who might stumble onto this thread. I figured out the steps: (Thanks Jsparta26)
After I flashed the prl, I called page plus and they activated the ESN. The MSID was the same as my phone number. Phone still didn't work, so i reflashed the PRL and then the phone was working. I didn't need to delete the APN, it was just working after. Now phone works for calls and 1x data. no MMS yet, got to figure that one out.
thanks for the help.
Your mms is also included in the apn file. Try the delete and restore method to see if works for you

I'm getting the message: Unfortunately APSs cannot be restored or deleted on this device because Android 4.0+ does not allow 3rd party apps to Write APN settings.
The Options in the Program are: Backup APNs, Restore APNs, Delete Backup Files, Delete APNs, and Donate.
Not sure what to do from here.
Ignore the part of backup, delete and restore. I was able to do this with an aosp rom and should work with a sense rom. You just cannot write to the apn file. Make a backup of your original apn, delete the current one, then restore using the page plus apn file and reboot. It should work. If not then manually copy it the apn file with a file explorer into your sdcard and take the page plus file and paste in the original location of the file and reboot. Let me know if that works.COLOR="Silver"]

[/COLOR]Which app are you using? Well if it don't work then I have another solution. Do you happen to know the settings of page plus's apn settings? Also do you know your msl code? If so, then open up your dialer and type ##3282# and punch in your msl code under edit. Once your through click on advanced and scroll down to the bottom of the screen and click on mmsc settings. If you know the settings you can manually input the settings in their correct spots. Once you do that hit commint changes or modifications at the top of the screen and hit reboot

I think I figured it out. In the settings for the program there is an option for "ignore ICS". i selected that and was able to delete and restore. looks like mms is now working, but it still shows 1x data.

yeah, 1x not so good.
Well I am glad that you got mms working. Not sure about the 1x signal, it could be a cell tower issue, not enough cell towers or that page plus's network is low priority. Have you flashed the latest page plus prl?

plenty of cell towers here, so that shouldn't be a problem. i'll try and flash the other prls and see what i get (right now i'm running the one from the main thread included in the rar). in the main thread i think there were problems with people not getting 3g. if i can't solve it with the prls, i'll have to comb through that thread for a solution.
Thanks for your help.

No problem. Just keep this in mind. Check to see if your radios are up to date on page plus's firmware. People used to have that problem when they went flash happy with the vm ruu ics leak back in may and messed up their phones with the dreaded 1x signal. Just something to think about. Good luck.

[Q] glaxy s ii data network not working.

I had custom android 4.2.2 and i reverted to the original 4.1.2 rom. Now mobile data isn't working. The phone was originaly on orange ro now it is on cosmote ro. It worked Before on cosmote with t e original rom and the custom one. I sent an sms and recived setings but it still doesn't work. It says it's activr bot i see no icon in the notification tab.
Any ideea?
Have you tried checking the APN settings?
I have an issue where i flash my phone with SlimROM and then Chrome and Whatsapp is not working on data. Then I realize that the ROM auto select the wrong APN settings. I entered the right APN settings and I have no issue with getting data.
Also check if all the apps are receiving data via wifi first.

Wifi works. I'm wrighting from my phone now. The settings where wrong but changing them is the first thing i tried but i didn't work.
I never had thisproblem before even when i flashed custom roms. It feels like it doesn't activate the net even if it says it does.
Got it. I had the settings for gprs and i needed the ones for broadband.
Hi everyone,
Thanks for your comment. It turns out the ROM was selecting the wrong APN by default. I switch the APN and updated the settings. Now it works like a charm

[Q] National data roaming in CyanogenMod 11 doesn't work.

Hi. Yesterday I installed latest nightly version of CyanogenMod 11. Before this, I was using [LINARO/SABERMOD] unofficial CyanogenMod 11 but I had problem with data roaming. I thought that in official build this isue had been solved. Unfortunetely, my data transfer still doesn't work. In the place where I live, there is very weak signal and I have to change my operator to another one manually. The problem is, data transfer works only with my parent network. I enabled data roaming in options menu and I edited build.prop file, where I set dataroaming=true; (although data roaming was enabled, in this file value was set as false). Tell me please, what to do. I don't want to restore stock rom.
Bump! I'm having same problem using CM11 4.4.4 (nightlies) for my S3-i9305. My carrier uses its own network but also uses another one as MVNO. Well, I connect HSDPA 3G on its own network but don't when using the MVNO, only Edge/GPRS (2G). Same happens using a SIM from another country, data works but only on Edge/GPRS (2G).
Yes, data roaming is enabled (the proof is that data works, but only 2G not 3G).
Any ideas? Thanks.
Solved
Ooops, it results it is a question of bands: the phone does not have all the bands we use here, that's it.

[Q] Can't detect mobile data after flashing Z2

I just flash my Z2 with flashtool using D6503_17.1.2.A.0.314_RU and uses custom rom ( eXistenZ ver. 2.0.0 for D6503)
After that, I found that my phone can't connect to mobile data.
I am sure that sim card is detected , mobile data is on and LTE is on.
But I still couldn't connect to internet
Thank you for any help.

simple thing that i couldnt found in rr 8.3.x

While i use wifi my mobile data remains on.how to turn it off i cant find any option on resurrtion remix 8.3x based? on android 7.1.2
If I'm not mistaken, there should be an option in the developers options which says to keep mobile data on while wifi is on (to allow for quicker switching)
