I have a Samsung Galaxy SII on 3 UK network,
since installing a certain ROM i keep getting a notification every time i reboot saying:
You have lost your data connection as you have left the network with data roaming disabled.
I can re-enable the connection by going to network settings and registering on 3(3G) network.
This is very annoying as its every time i reboot and im rebooting a lot as im trying to find a ROM i like.
How do i stop this from happening?
Also how do i install cyanogenmod?
I've only been rooted 2 days so if anyone knows any good ROMs or apps or any tips for someone new to root please comment.
Its ok now

This Galaxy Note is my first Android device ever. I have rooted it and was downloading some apps. Basically following a post of the most important apps to have once rooted. I downloaded Juice Defender and enabled it inside the app on the recommended setting for new users. All the other apps downloaded I have not messed with anything that would alter any part of the phone itself. I wanted to start at a better battery. Now when I leave home and do not have a wifi connection my phone says that the data network is disconnected. I tried to disable JD which did not fix the issure, and then I uninstalled it and rebooted. Still same problem. I'm so new to this I don't know what you might need to know to help me get my old data values back in place from what JD altered. So Please help me get my now useless phone back up and running. Also, please be patient with me and what I'm sure are stupid questions regarding this issue. I'm just trying to learn here.
Thanks,
Open Settings -> Wireless and Network -> Mobile Networks.
Check to make sure 'Use packet data' is on.
If so, open 'Access Point Names', AT&T PTA should be selected.
Make sure that you contact AT&T and have your phone set on their network. It is an LTE phone and it needs a specific data package.

That is exactly why I aborted Juice Defender. Try Greenpower, https://play.google.com/store/apps/...=W251bGwsMSwyLDEsIm9yZy5ncG8uZ3JlZW5wb3dlciJd.
I was having problems with JD as well. My data icons and bars would show but I would have no cellular data. I uninstalled and everything worked fine after. It's weird because I had no cellular data problems with JD on my Inspire.
Anyways I find that you don't really need JD if you're using an app like setcpu or system tuner which puts the phone into deep sleep when not in use.
u can try all those there good tools..check data enable if its on and still no connection .pull sim out and power on without it....turn phone off put sim back in power on to trick the system..reboot ..and see if that works..just make sure u have data enabled first and data on.....before doing this...hope it helps

That happens to me,too.
And it lasts for about 2 months,seems no solutions yet.:crying:
One possible reason I got is like: every time the phone encountered a signal problem,such as Airplane Mode,weak strength,etc.The phone react much faster than the SIM card,and then the sim card is not really initialized,the phone itself resumes up,and got a wrong MCC/MNC,both are 000.
No solutions on photons yet,because there seems no one works on Photons' framework.That could be changed by correcting the framework I think,because same problem happens on so many types of phones,such as ST18i.And both are resolved.:crying:
You can fine more information on CM's official website,there are many discussions on resolving other types of phones.

Hello there, I´m using the phone in Perú in a GSM network, with stock 2.3.4 and rooted. So far my MoPho has never lost the APN configuration. Are you only losing your 3g connection and your APN? Because I do lose my GSM signal sometimes in a day, but for some seconds only.
Hi, I am in Sweden and I am using miui 2.6.1 ics rom and I have no problems also I use a app called apn global its a quick way to set up apn's it reads your sim card.
GSM apns disappearing
Hi
I am on Cm9 aokp build 38 and i also had this issue of apns disappearing ( I am in India using GSM) The solution is to flash forceroaming.zip files from cm9 fixes files in this forum and flash it and restart it. If you dont see any apns manually you enter the apn value of your provider and save the settings and voila the problem is gone:highfive:. Sure this fixes the problem but I dont know how:fingers-crossed:. experienced guys may help but i am experiencing uniterrupted data after this
Used to have the disappearing apn problem for cm9... but since recently flashing to cm10, the disappearing has stopped... In the "Manage Apps", i noticed that the apndormancy service was stopped by default for cm10...probably thats what stops the apns from disapearing when phone "sleeps".. If theres an app that can freeze services and you can get it to freeze the apndormancy service, i think this would stop the disappearing.
Cm10 all data problems have been eliminated apns don't disappear. For cm9 you can flash forceroaming.zip

so after i reboot my phone, during the lock screen, after the message that shows preparing sd card on the notification bar, a triangle shows up for a few seconds on the notification bar then disappear.
it was "You have lost data connectivity because you left your home network with data roaming turned off."
it only shows up during first lock screen when i reboot the phone
nobody has an answer?
I dont know why it says you have lost data connectivity when i dont have 3g on my sim and im on wifi and its working just fine

I have the same problem and no answer. I'm running Dillidroid ROM, but the issue also appeared on other roms i installed so they are not the problem
Nobody knows?
At a complete wild guess, I would say the ROM is expecting a data connection and then can't get one so it flashes up that notification.
I would suggest trying another modem from the modem thread in Android development, maybe one for your network specifically.
Of course, I have not seen this before so just guesses and suggestions

I would Suggest you to Flash another Modem..
Also try Settings > More > Mobile Network > Network Selection
Try setting it to Automatic.
If nothing Happens try option 1

The "automatic" solution didn't work for me.
But after I set the device to "WCDMA only" I have not seen the notification.
Try that.
I believe this happens when you drop from 3G to 2G network.
I have this happen regularly since my providers 3G connection is ****.
This error is shown when the fone dearched for ur carrier. If it's both gsm/cdma, u'll always see this error. Choose CDMA or GSM only.
This may affect the battery life of the fone sometimes..

I don't know if its my network or the kernel. But after flashing the 4aceskernel last night i enabled the fast charged and left it all night with airplane mode on,so i don't get bother. Now this morning i disable airplane off and fast charger off,and i enable my data and roaming, after that i try to get on play store,and it stock on loading with the circle going around,after couple seconds it says connection timeout. I dint pay attention to it, i left it alone.later on i try to use the Facebook app i couldn't it stock on loanding and after couple minutes it says network error. I went to my browser and search something on Google and it was working. I search the letters b,c,d just to check if it was my network. But it turn out that it wasn't my network at lease that's what I'm thinking.so i had some twrp backups from different ROMs and in all of them it still the same problem. I can use the internet to search even i can use xda and i can download ROMs but i cant use the data on any gapps. Or even the Google voice on the stock,opera,chrome,Firefox,dolphin browser. Not even gmails or Facebook. Yes my apn settings are correct.my accespoint is selected in my network.by the way i use net10. I search on Google about this problem but it just show different problems with the network nothing related to my issue. Help in need! Remember all this happen after flashing the kernel #31. Just to get this clear im not blaming this on the kernel because i don't even know if the kernel have to do anything with this,since I'm the online with this issue .but i came here because this the only thing i flashed last night. Any help will be appreciated guys/girls.
I'm on lattes jellyb*m ROM but like I say I went back to stock roms even GB,ICS,jb nothing that I do make my data works correctly.

Hi all!
For about a week my International Samsung Galaxy S3 (i9300) have been experiencing network issues. At first I have full connection and after a while the network cuts off and my sim card disables (in the status bar the mobile data icon shows "no data sim") and then it switches back on and everything works.
This process happens constantly.
I have tried numerous solutions like flashing new ROM and trying to view logs.
It still shows the IMEI and I don't want to unnecessarily modify my EFS I've read that it can cause serious problems.
What is the problem and how can it be solved? Any help is most welcome and I will send logs and info if needed.
If the problem is already solved please show a link because I couldn't find anything that helps.
Thanks in advance!
I'm having a similar problem with my I9300 as well, the difference is that the network only gets cut off when I try to make a call, and then it comes back after a few seconds, and it doesn't show 'no data sim' it just stays with no connection (no bars). Messaging and 3G Data connection works fine.
I already tried to solve with several methods, the only one that I didn't try is to Odin flash back to stock, wich I don't really want to. I'm running cm-11-2016 at the moment.
