After installing MIUI ROM on my galaxy s4 my network has been messed up I tried installing just about every Rom there is for this Phone. I have data and can text people with a little window coming up and saying no network but it still goes Through. I can only get 4 g and no 3g my phone just doesn't have a signal unless it is connected to 4g. I can't make calls at all, I tried a factory reset and it changed my signal to roaming and I have no data and then I use the Samsung Service mode app and click on LTE and I have data again. Also I tried using Odin to flash back to stock and it always gets stuck at getting pit for Mapping. My brother has this phone too and it work perfect for him, but not mine. Please help I'm all out of ideas.
Also I tried changing the Sim 2 times, could it be my efs is messed up.

i even tried fixing it using Samsung service mode

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
Yesterday I noticed that my phone is no longer able to send or receive phone calls.
It's got a good 4G signal and data works, but the "CDMA (3g) Signal Info" in the Advanced Signal Status application is 0%.
I don't know if that zero CDMA signal is normal if you're on 4G, so maybe this is a red herring.
I'm considering trying to ODIN the MK2 Modem onto it. Any other ideas?
You're probably on LTE only mode use an app like phone info to change the radio bands back to lte/CDMA (prl) auto mode.

Flashing the MK2 modem leaves me at state "No Service". This is not an improvement.
It's now asking me to switch to Global mode.
I tried using "Phone Info",
Network Type is 13 (LTE).
Phone Type is 2 (CDMA).
SIM State is 5 (Ready),
OK, any other ideas?
Damn wish I could help this is a weird one. Do you think you did anything before hand that might have affected it?
Just to be clear, when you go to mobile networks settings your network mode is set to CDMA/LTE?

Yup, it's a strange one.
Network mode is LTE/CDMA.
More data - I just plugged in my UK SIM. It came up, asked me to switch to Global mode, and now shows coverage as AT&T UK, which is what it has done in the past. GSM is apparently working OK. Network is AT&T HSPA, Roaming mode.
Power off, re-insert the Verizon SIM. Service says "Emergency Calls Only" due to Global mode.
Switching to LTE/CDMA gives me an "Attention" box saying "Searching for LTE/CDMA" with OK and Cancel buttons.
Pressed "OK" and now, instead of "No Service" it says "Verizon Wireless".However, still no phone calls in or out.
I just decided to use Safestrap to install Hyperdrive, figuring that if it was something corrupt in the base ROM it'd be obvious.
Unfortunately, no luck - it has the same "No Service" problem, and still can't make or receive calls.
I think I've got broken hardware.
For the record: Factory data reset brought it back to life.
I haven't any idea what did this, but I don't care since it's now working and I don't need to stand in line at the vzw store.

If I'd have seen this a few hours ago, could have saved you some aggravation. I've seen on here before where a factory reset was the only thing that seemed to fix this weird issue. Glad you got it fixed. If I remember correctly that user was messing with their apn settings.

I don't mean to hijack the thread, but I had a similar (but not the same) situation yesterday, and hope that I can contribute help to anyone in the future using the search function.
I had fully-functional 4G and 3G but could not make/receive calls. I could even text. The phone showed 3 bars of signal, but when I called a number, it went to the circle with the line through it. The message said something like, "Out of network range". (I was right in the heart of my home city).
I rebooted and it said, "invalid PUK"
Anyway, I ended up taking the SIM card out and reinserting it, and the problem was fixed.
I am using the rooted/deodexed international debloated stock 4.3 rom. I wonder if my next step would be to unlock the SIM.
Anyway, I hope this helps someone....and glad to hear that you got your problem fixed!

Did you use Odin?

That should definitely work.

I booted into stock recovery and used that to perform a factory reset.
Forgot about the reset after Odin, thanks-
Unfricken believable this worked, Thank you! I suddenly had the same problem with my S4 from Verizon on MK2 I tried to make calls but I could not get a Dial Tone and it would drop the call all at the same time go to no service mode. It was actually rooted but on stock rom, worked fine for 3 months and all of a sudden I kept dropping signals, rebooting, etc didn't help. I even used Safestrap 3.71 to do a recovery of stock rom to day one stock rom. (When I first got the phone and rooted) AND I did a factory state reset in Safestrap and that did not even fix the problem. I was going to try Odin reset, but I tried the Factory reset using the phone's options by going into "Settings"-->"Accounts"-->"Backup and Reset" and I unchecked data backup and automatic restore as I already had backed up my contacts, etc. using Samsung Kies 3. I just clicked "Factory data reset" and confirmed the options when prompted and after reboot, BAM! everything is working like day one!
My only culprit maybe is that this may have occurred when I tried to do a unlock via Service Mode menu and it screwed up with the Global settings or so and from there it kept asking me if I wanted to switch to global mode. Which it still worked fine for 2 weeks after the service menu mode. What I thought my phone was unlocked, I'm still not sure if the service menu mode method unlocked my phone or not but Factory reset via phone's options works wonders! I was just about to head over to Verizon to help fix my issue.
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...
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.
Problem occurs with stock Rom. And I already tried CM11 and others ROMs.
When I turn on the phone, everything work great, both SIM registered, calls working, 3G connection. But after hours using (sometime 2 hours, sometime 6 hours aleatory) the signal indicator remain showing full signal, but is showed on "about" that network and phone number is unknown but still show type of signal (3G, Edge, UTMS). On both SIMs. Emergency calls only. Is like that could not read the SIMs card. And I can´t receive calls or make calls of connect on 3G. So, when I realize the problem I restart the phone and it come normal for hours. Airplane mode don´t fix, just restart.
I Already tried with stock BUBUANH1 (my phone is GT-i8552B) and BUBUANF1.
I believe that is a soft problem because my wife have same phone (both are after jul 14) and the problem occurs in both. I think very improbable to be hardware problem in two phones.
On my mind, this problem always occurred in the past, but I don´t had identified yet. The SIMs card were tested on gt6313 and worked well for 2 days.
I going crazy with this.
Could you tell what can fix it? i already searched for the modem.bin to this phone but cant find, anyway i think that if it was the problem it would never works.
First time when I used odin to flash, I chosed Phone instead PDA and flashed the stock tar file. The phone get a loop, but after I flashed using PDA the phone worked fine. Could this to be the cause? Could corrupted some thing?
