Hi everybody, I am quite frustrated at the moment, since my S2 has driven me up the wall all day long. To cut a long story short, for some reason my mobile data is unusable. For some reason, yesterday I flashed a modem (...KS3 or somethng, i had already used that file previously, and worked), and after rebooting mobile data was gone. Then I don't recall what I did to troubleshoot the issue, but I came across these results:
1 - Managed to get the H+ icon back, but no internet, I could see from the arrows on the icon that it tried to connect but couldn't.
2 - Tried to switch between APNs, but with no success. On PAC rom an apn got the state 1, but still no internet.
3 - Tired with dirty flashing and no success, I decided to start over and do a full wipe and flash of CM11 official and on first boot, still no internet.
Right now it's sitting there, with no icon next to the bars, and i can't make any calls nor send SMSes. What do you advise me to do? I flashed a modem when I was on CM11, right before bosting this and still no luck.
Please give me a hand, I am starting to grow a bit desperate, thinking of an hardware issue. Never did this before, if this can help
EDIT: It is now in state 1, the icon H+ is is there, but i can't access the Internet...

Interesting problem that I suddenly have after installing rom. First I have been installing just about every rom has come for the last 6 months. Today I installed latest Carbon ROM from here http://forum.xda-developers.com/showthread.php?t=2310695 today and it installed ok, but upon booting for the first time, it got stuck the setup right at the beginning where I press the language (English). It just sat there and didn't do anything. I tried reinstalled the rom, and it did the same thing.
So I assumed a had a bad download, so I went to restore my daily driver backup rom (Zone sense 4 rom from here http://forum.xda-developers.com/showthread.php?t=2116509). But now I have no mobile data or mobile connection at all. I get a triangle next to the bars and whenever I restart phone I get this message "Global data roman access is allowed. Significantly higher charges may apply". I have never seen that before.
I have tried removing sim, toggling all mobile network options (CDMA, global, roaming, etc.) and I still get no connection at all. Any ideas here? I am on Verizon.

Thanks. I did that and it worked. Any thoughts on how to avoid that in future aosp roms? Did I do something wrong or is it totally random?

Its apparently random. I've had it happen twice, once back non CM10 when it just got RIL going, and a build ago on Carbon.
I'm going through this right now. I rru'd and can connect to 3g and use the data but no texts and when I try to make a call I end up with a Verizon message saying my number is inactive. Everything works fine on my backup phone. So its not a problem with Verizon
Edit... I'm going to ruu again and factory reset before booting because I think I remember seeing that posted at some point

EDIT 2.... re rru'd still having problems it will not make calls and will get 3g data when set to roaming which it seems to be on with the triangle above the signal.
anyone know the Verizon apn's i only have verizon internet in my apn list.
Edit 3 All fixed. i was factory resetting in stock recovery to no avail but a factory reset in sense itself worked
Hi everyone would love some help if possible...I had flashed Sun Dream's ROM a few weeks back and everything was working great except for Search and MMS...so I tried wiping and reflashing today, and now it seems data isn't working...when I flashed the ROM the first time, I was getting the 4G icon and data arrows, but now in Settings it shows Mobile Data as "Disconnected".
I've tried turning that or Airplane mode on/off, rebooting several times (with pulled battery), editing APN settings to no avail. Anyone know what to do here?
I sort of remember the first time around that some stuff wasn't quite working when I first flashed but then it did (like push notifications)...wondering if this is going to be like that (and why...)

Several of @sun_dream's ROMs are GSM only, no CDMA support, meaning they don't work on Verizon... are you on Verizon or a GSM carrier?
Thanks all for your responses - it's this one: [ROM][Sense4.1+4.5+5.0]【GSM/WCDMA/LTE】+【Global】+【CDMA/LTE】
But...it looks like data is working now, and I got a text from an iPhone user...which I previously was not able to open (since they are all MMS's). So it looks like all my issues are resolved. Kinda like I alluded to in the OG post, after the ROM settled it seemed to be fine...I still don't get why that happens...I just panicked since it seemed like there was no data for several hours.

Sorry - forgot to respond to this - I am Verizon - I posted the ROM link in my previous post which does work with CDMA and is working for me now. Thanks!
So for the past literally 3 mmonths, I have been unable to send a picture message, or do anything "data" wise (chrome, playstore, play music, games that require a connection) while "on 4G LTE.
The interesting thing is this...when I flash Jasmin or Skydragon, it works for about 30 minutes, then it NEVER works again once I disable data then turn on wifi, then reverse it. All I get on Chrome is "ERR Name not resolved".
Ive seen that this is a APN problem but I am unable to add one, and there is only one apn in the settings...does anybody have any idea how to fix this? I have unlimited data grandfathered in and I have been completely unable to use my phone outside of my house.
Any help is appreciated!
I understand I dont have signal in the screenshot...I had full bars at Kroger last night and was showing in amazement how I couldnt do anything but take pictures...lmao
Able to change APN in Cyanogenmod...
So I backed up my Skydragon rom, wiped everything off the phone, then flash Cyanogenmod 12 with Gapps and I have been able to get on the web and send MMS pictures ALL day even with toggling wifi/LTE and reboots...I also noticed that there is like 10 different APN's to choose from on Cyanogenmod AND I can MAKE a NEW one.
What gives?...
Ok...I lied. Getting error not resolved again...

I will guess it's a bad sim card. Call them and they may overnight one if they see you've used no data for three months, or stop into one of the dreaded Verizon stores and pick one up.
I completely wiped my phone before Installation of Cyanogenmod and had data for like an hour, and i completely wiped my phone again and reinstalled Jasmine, and i've had data for 2 hours now. I'm trying to test slowly where data quits connecting. It will SHOW 4G, full bars, but can't use it...it just says not connected to data and bla blah blah

Go check to ensure you have an IMEI number. If that is blank or all zeros, that could be the issue.
If so, getting a new sim card might fix it (just go into the VZW store and it should be free) but I would flash back to stock first or they will refuse to help you. Or you can restore it yourself manually. Or, if you're IMEI number is still there, then you'll still need to flash back to stock before going into VZW to get a new SIM card.
I've had it where I flashed back to stock using a TOT file and it wiped my IMEI number for some reason (the next time I did, it didn't wipe it so go figure).
Go to the following link (if you're IMEI number is wiped) to fix it. Hopefully, you still have your box the phone came in. Otherwise, you can remove the battery and find the number on a sticker in the battery compartment:
http://forum.xda-developers.com/showpost.php?p=58915450&postcount=3
In that post, I explain how to restore your IMEI number.
I found the fix.
Okay so they recommend after booting a rom to let it sit for 10 minutes. I found in my case that this does NOT work. After multiple testing scenarios and a few weeks I discovered I need to let my phone sit for 30 minutes. Thats phone wiped, Jasmine installed with mods and all the shebang, and after you hit reboot phone set a timer somewhere to NOT touch your phone for 30 minutes and Data has never failed me. Now it is ENTIRELY diffrrent from letting it set to 10 minutes. My family has 6 G3's and 3 of us would flash with a ten Minute sit, and 3 with a 30 minute sit and we had almost PERFECT results with this.
Im not expert but I think its not giving the phone enough time to call for apns for the phone anf since you cant ADD any, you S.O.L. until you fix it.
We usually have 2 bars of 4G where we live so I almost wonder if its because of that. But you think two bars would be enough in 10 minutes to grab the proper apns.
Once again, 6 phones. 3 different houses. All samr results.
Wasnt a bad sim card...wasnt a imei wipe. It was NOT enough time letting the rom sit.
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.
Hello guys, I'm having a huge issue with my mobile network.
For the past two weeks I've not been able to make use of my mobile network correctly, it sometimes works, but most of the time doesn't. The icon in my status bar shows there is activity, it's fully connected to 3G or LTE, even with full bars. But all my apps like Telegram, Pokémon go, Messenger and the likes are stuck "reconnecting" to the network, as if my phone doesn't have any reception at all. At some points even SMS messages refuse to send, even though I've got full reception.
I've already gotten my SIM card switched out, attempted multiple clean flashes and the issue still persists.
Phone: Oneplus One
My current firmware: 0.1.c1.11-00006-M8974AAAAANAZM-1
Current ROM: idprophecy's unofficial optimized lineage-14.1-20180413-UNOFFICIAL-bacon
Current Recovery: Kutep0v TWRP 3.2.1-K2
Is there anything I can do? I'm getting really desperate.
This is my last plead on this forum, as I haven't had any response from anyone since april 25th, I've got nothing else to do but wait. Can't find anything on the internet about this issue, you're my last hope.
Have you tried flashing to stock version?
