Hello guys
I have a problem with my s4 i9500 bought in dubai. I bough a simlock free cellular and after updating it to android 4.3 i couldn't register to my carrier anymore. I tried to downgrade to 4.2.2 and register and it didn't worked anymore, I also tried to install a custom room but it didn't worked too.
Any tips how can i repair it ?
Sim card works on my iphone 4 perfectly, so it can't be it.
P.S English is not my main language so please don't be cruell.

@edit
had network for a couple of seconds and it's gone
Hello i recently bought a samsung note 2 ( sgh-i317m ) and was running claro network firmware 4.1 which was network locked and i purchased a network unlock serial and unlocked it. since i felt the 4.1 was so outdated i updated to telus andriod 4.3 via odin. everything was working fine for a day i was making calls data was working everything was sweet and yesterday out of nowhere i get a invalid sim card inserted/network lock. should i change to a different 4.3 firmware or what can i do? please help any suggestions on what can i do please helppp im clueless
Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

I'm having the same problem, but with G900H. I have stock firmware, rooted and everything's working fine until suddenly, I have no network. I restart the phone and get network again but only for a couple of minutes.

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:

with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch

My nexus 4 was working fine like 1 year untill we cut off our mobile carrier ,
now , when we enabled the carrier back on (sorry for my bad English , I hope u'll understand me)
the nexus 4 seems to recognize the sim since it writes : EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
but i cant get it to work with the sim , the sim works perfect on my moms iphone so its not a problem with the sim .
the sim wasnt cut or anything . and it was working just fine for 1 year . I tried flashing google stock 4.4.4 with a toolkit ,
didnt work . Still getting the same EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
and when i tried to select my carrier manually ,
I got the cannot connect to this network . try again later massage .
I honestly tried everything I know of .
Im starting to think its a problem with the device and not the operating system .
since i flashed a brand new stock image and it didn't work !

I don't think your sim is locked. Check out this thread. You can try flashing a different ROM along with updated radio. If all else fails try another sim card.
check you imei number on the phone with a telecommunication website in your country, a friends phone had this similar issue, it it was locked from the networks in the country due to the contract not being fulfilled so they blacklisted permanently to prevent him from using it

Hello Guys,
I bought an S4 and I discovered that I was scammed (it was the sprint version and not the GT-I9500 as it was indicated on my about phone tab). It comes with 4.4.2 and everything was working fine (the only things that bugs me was that I was unable to receive updates). Recently I encountered some little issues so I decided to install a new ROM. I tried the Vanir and Commotio ROM and for a moment I was super satisfied (it was an amazing experience). However after putting back my SIM card, each time I try to deal a call, I got the error "mobile network is unavailable". I thought it was an issue from the ROM I used so I tested the LineageOS and same issue. Finally I tested the STOCK ROM Lollipop and the same issue again except this time the WiFi does not work. Now my phone is completely useless, so can anyone help please ?
PS: When I go to settings->about->status, everything about the SIM info(network, my phone number,...) is set to unknown. the IMEI is intact (non null). IMEISV is 00.
