unable to connect to mobile network - Galaxy S 4 Q&A, Help & Troubleshooting

hi, yesterday i had this problem and i can't make call or send sms and navigate on internet.
wifi works
i was on cm13 original , i tried to clean flash again cm13, clean flash optimized cynogenmo13, flash update boatloader and modem and now i tried to flash last samsung stock rom but the problem is still here...
i tried to put my sim card in my dad's phone and it works, i tried to put his simcard in myphone and it doesn't works, so is a phone releated problem
what can i do?
thanks
p.s. i'm from italy and i'm on TIM

There's probably something wrong with the SIM tray.

in that case can i simple change it?
i forgot to say an important things, when i boot the phone, the phona asks me the pin like usual

Is the phone asking for the sim pin or phone pin? If it's asking for the sim pin, it could be a software problem.
You flashed the latest stock rom using desktop Odin?

i flashed first the last boatloader and modem, nothing changed so i flashed the last firmware for my country using odin and nothing changed again :/
If i try to make a call it say "non registrato sulla rete" that means "not registered on the network"
in settings, if i manual select the network, the phone try to connect but after few moments say "this sim cannot connect to the network" or something like that, but the same in another telephone works!

Is the phone asking for a sim pin or network unlock pin? Does the phone show the correct imei? Could the phone be blacklisted?

the phone asks sim pin
the phone show the same imei that is written on the case
i don't know if could be backlisted, is a phone bought by a industry that have a contract with Vodafone, i also asked if the industry had some problem with Vodafone but they said no so i think there is no reason to black list
thanks for the help!
edit:
the guys from the factory just call me back and he said that he was wrong, they had a misundersteing with vodafone and the locked the phone, now they clarified and they are going to unclock it in 72hrs!

I got to say, your panic is not going to help. First I want you to take a deep breath, and relax. Now, in order for us to help you. We need to have more information. More specifically, the following: Do you have roo. boot loader unlocked? What carrier are you using? What ROM and kernel you're using? Is your sim good? Are you using a micro sim? What radioband you're using? Is your sim card adapter slot damaged? Is your imei bad? Now you need to put this in a detailed explanation with what you have done with your device up until the point in where your phone stopped working.
stock room,one week old device, no root or nothing similar,the phone doesn't show imei number just blank window (*#06#)

If it's stock and all you did was do an OTA upgrade to 4.2.2 have you tried talking to your carrier? Being only a week old I would use their assistance to your advantage especially if you did not unlock/root the device. (not sure how you came across the sim card, if it was sold with the phone like it was with mine at T-Mobile, or if you just got the phone and then used a sim from the carrier).
but t mobile will send nexus to repair's for a month so do not want to be w/o my phone for so long.I'd like to solve it home...

[Q] i9505 cannot register on network

Ok so here's my problem.
I have an I9505 previously with a GE custom ROM and modem version XXUEML2, everything was working fine so far, the only "strange" thing was whenever I reboot the device the Cell Network will take about 3 minutes to reconnect, and I constantly lost the 4g connection which I attributed to problems within my carrier.
So a couple days ago I re-installed my custom ROM (was having problems with the Kernel) and after it boot back I wait to my Cell Network to connect, which never happen. So I went ahead, format everything, re-install the custom ROM and no luck.
I tried everything, updating the Baseband to XXUEML6. Install the Stock ROM (which was locked, but the store where I get it unlocked it by warranty), install another Stock ROM (right now I have the I9505XXUFNC4_I9505PHNFNC1_PHN ROM) and I still cannot get signal).
Did my modem just died, or the "warranty" guys unlock my device in a wrong method. I don't think is a problem with my IMEI 'cause I still have the same as the dive box says.
Hope someone can guide me before I take it back. Thanks.

Well, when I bought the device, it was intended to be unlocked, but for a strange reason my device (only mine 'cause we bought 2 the same day) came carrier locked (MEO from Portugal) So I sent it back to warranty. After a week I get my device back "unlocked" (Same ROM, IMEI) but I notice that it was rooted, which only makes me think that they take it to a third party which unlocked the cellphone with a method that required root. I didn't care, I had signal and 3G,

There use to be possible using this guide, with the old firmwares as far as i know is not possible anymore unless you still have that firmware
http://forum.xda-developers.com/showthread.php?t=2282683
The other way is by an unlocking code ( you can buy in many places) once is unlock , stays unlock..no matter what you flash
Try something go Settings/connections / More networks/Mobile networks/ network Operator/ choose your carrier and see if it let you register, try others and see what kind of message you get

Already tried to choose my carrier, but sometimes it doesn't even appear, and when it does, connecting to it just throws and error saying "Not Registered On Network".
What I fear is that somehow they unlocked it using the Ariza patch (or other unlock method) which should not be used.
Also after digging some info, that kind of error happens when the device have been IMEI locked, which could be also a possibility given that my SIM works on any other device, but not otherwise. I will have to give a call to support service to discard this theory.

Hi ,
I also feel the same that is the problem , it has not been unlock right.
check with them , let me know what they tell you.
Ok, I have more information, typing on the dial *#0011# to get the Service Mode Menu, it says at the bottom IMEI CERTI: NA. But if y dial *#06# I get my correct IMEI, is something wrong with the EFS folder?

[Q] Sim card problem

Hello,
I bought my Note 3 mobile and decided to flash C-Rom!
At the morning of one day I flashed the rom successfully. Later I installed all apps I wanted. I have my phone rebooted a lot of times with no problem. Some time at the afternoon of the same day I pick up the phone to stare at it! I activated the LTE option and deactivate it again. This was not the first time of doing it! After that the network signal was missing! I rebooted the phone, but it doesn't ask me for a PIN any more. I used my sim at another phone and it asked for a PIN. I used another SIM at my phone but it didn't ask for a PIN.
After dialing *#06# at Dialer a popup dialog shows up. The title of this dialog is MEID and the content is B0000000!
At settings>About phone>Status> the MEID is full of zeroes but the IMEI seems OK.
At the same screen i see the following:
Network - Searcing for Service
Mobile network type - Unknown
Mobile netwok state - Disconected
Service state - Out of service
My phone number - Unknown
MIN - Unknown
PRL version - Uknown
ICCID - Unknown
Thanks everyone in advance
Very strange.... without doing anything like flashing stock or modem?????

The reason is unknown but it seems like your phone lost a valid IMEI/baseband.
Can you check the Baseband version?
Try to flash the stock firmware, or flash the baseband for your device.
The problem suddenly appeared and that's what makes me feel uncomfortable. The baseband number is N9005XXUENC2. I will try to flash whole firmware, but does anyone know how can I flash only the baseband? I don't want to stay with the original ROM!

Extract modem.bin and NON-HLOS.BIN files from the stock firmware, and flash via Odin.

It is my first Samsung. Could you be more specific? How can I extract those? Can you guide me through?

Finally I was able to solve the problem. It is a problem with C-Rom and 4g option. I am going to write a new reply by tomorrow and also to the forum. I appreciate the help guys.
Thanks a lot
The problem is with the LTE activation/deactivation.
I am from Greece with COSMOTE provider. Here, in Greece, at the moment we have to pay an extra fee to the provider in order to have the option of using 4g. The steps as I believe are the following:
1). I am not paying this fee at the moment so I am not able to use 4g.
2). I activate 4g and immediately I deactivated it. I did not want to open it, just touching the selection at the notifications. This option is at the notifications when you slide down the notification bar using 2 fingers.
3). Then the signal goes off and I had to re-flash stock rom once again before flashing the custom rom. The problem has to do only with the signal and everything else works as charm in the C-ROM.
The C-ROM version which has this problem is this C-RoM-KK-v7.1-20140622-hlte.zip

Simunlock Problems

Hey there,
I got a I9505 that doesn't detect my simcard (if i put it in it still say pls insert simcard like there is none). so my guess was carrierlocked...
It also doesn't ask for an networkunlock code .. so i didn't wanted to buy a code on these websides because i didn't know where to enter the code.
Well I've tried the trick with the *#0011# and it doesn't go into the Service Menu.
The phone is on 5.0.1 could this be the problem ? Is there a way to downgrade?
Or do i have to falsh the modem in any way?
Till now i've just changed the FW with Odin to the DTB Version.
I'm kind of scared to try other things if I'm not sure what they do...
I'm really sorry if the solution is in a thread i havend found or just overlooked
thanks for your time and help
A properly working SIM lock would recognize the presence of the SIM card, and when you unlocked the phone, would prompt you to enter the unlock code. Therefore, a carrier lock is not the source of your problem. Unfortunately, yours is a hardware problem, and based upon your description, it's a motherboard failure, rather than a SIM card tray failure. It cannot be the SIM card tray because a SIM card tray failure would not ask you to insert the SIM. Instead you would have a circle with slash in the notification bar to the right.

Thank You for your help,
So in the mean time I successful downgraded to 4.4.2 (cyagogen)(and upgraded again) found a soulution to flash and access the modem so i could do the trick with *#0011#...but it's still not working.
I just don't to belive that its a hardware problem. Is there anyway of another software Simlock?
Because the Network Conectivity bar is showing 3 bars.
I got it (not so) cheap from ebay, so could it be that the imei is block in the network ?
Thanks agian for your help
IMEI could definitely be the cause of your problem, especially if you actually do have a signal.
It is showing 3bars but not the H for HSDPA but it also shows those bars if no sim is insert so...
The imei ist blocked ?
Guess there is no way to change it
Sent from my Nexus 4 using XDA Free mobile app
If no SIM card is inserted you wouldn't have any signal, but a missing SIM card indicator. This behavior confirms to me that you have a hardware problem of some sort. You need to have the device looked at, because software is unlikely to be the source of the problem.

S8 unlocked but no service

I bought used S8 that had clean IMEI (not blacklisted), it was locked on Sprint and with financial eliglibity. Before I got it unlocked it didn't recognised any sim card, after unlocking it did regular setup on my ATT card with all the ATT apps but it doesn't have service. Then I tried with Verizon SIM and it did the same, regular setup but no service. What do you think what's the problem ?
Phone build number : R16NW.G950USQS3CRE2
Is it rooted, and if it is, have you uninstalled any system packages
If not, try a factory reset and making sure the sim is active and APN settings are working and you have chose a network

It's not rooted, I did remote unlock with unlocking service and they flashed original firmware on it, nothing should be messed up.
I did factory reset few times as well as network reset. I double checked APN info and ofc it's setted up together with card.
I forgot to mention that phone is not showing up IMEI, actually nothing when I type *#06# in dial
that mean you lost imei ....flash factory firmware by yourself...it will do the trick

Can you explain me which one I need ? What about bootloader, is it the same ? I've checked thread about bootloader and mine is "carrier firmware", not unlocked.
Which career search for career. Look at the build number in abiut and search for that.
I'm using ATT and my phone was locked on Sprint, so I flashed Sprint firmware and It's the same. I put the SIM card in, it did ATT setup and all of the apps from carrier but it's still block sign instead of signal sign in top right corner and airplane mode is light blue (not usual blue like when you turn it on)
At least this time it's showing up imei in dialer
I couldn't find ATT firmware, if someone knows there's my build number in first post.
