I did purchase an unlock code from unlock-code-central.com. Put a different SIM, typed in the code, got the message all went well, however phone says "emergency calls only"
Can anybody please help me with this?

There was no need to purchase the code as there are several threads here on how to menu unlock it. But since we are beyond that, I'm guessing the other SIM is not provisioned and has no service on it. Try using a friends T-mobile SIM. That's how I was able to check the menu unlock method.

Thank you for your answer.
I used a regular size Vodafone SIM which I just used in Europe last month, on my other phone, so that SIM should be ok.
However I used a SIM cutter to transform in into a microSIM . Visually looks ok too. Could it be that in this process the SIM (now microSIM) got damaged somehow?
When I first insert it, I was prompted for the unlock code, which I typed, got an ok message, but that's about it.
Now says "emergency calls only" and it does NOT prompt me for the unlock code anymore.
Original ATT SIM works just fine.
There's more: I just put that Vodafone microSIM into my wife's phone (which is unlocked) and it works fine.
So bottom line, I used an unlock code which apparently worked (got the message "network unlock successful") but the phone does not appear to be unlocked.
I will definitely try a T-mobile SIM as soon as I find one, but in the meantime which is that "secret code" to check network status for this phone?
*#7465625# does not work and returns "connection problem or invalid MMI code"
Thank you
anybody has the answer to my question ?

my phone is definately locked and when i put in a SIM from another carrier, it does not ask for a SIM unlock code.. it just says SIM Locked with a dismiss button.
How can i get my phone to ask the unlock code?
Is this some setting in the build.prop file? i went through the whole file and tweaked a few ettings relatd to PUK but no luck.. any other settings you can think of?
Hello, I used the SIM unlock method from the thread here on XDA and was able to successfully unlock my phone and use it on a foreign network. A bit later I had a problem with my Bluetooth so I did a factory reset, and now the phone says 'sim not allowed mm #3' when i put in a foreign SIM.
The frustrating part is that when I go to the unlock menu there is a list of various logging methods, but every one of them says 'Phone is not personalized' which means the phone is unlocked, so there is no way to reenter an unlock code.
Is there a wwayas to check and change the software lock status?
Hi,
I need anyone's help for my mobile as it says Not registered on Network when I tried to call although the SIM is already inserted .
- This mobile was for Africa & ME version but already opened in ASIA (Non competible regaion ) and started asking the code.
- So it was routed by SU and tried to unlocked it but failed
- Then the mobile was sent back to Saudi Arabia, where I unrouted the mobile thru SU (by complete unroot option in side the SU, installed original firmware successfully. But when I try to call, it display a message as " Not registered on Network"
- I already inserted a paper between the SIM & SIM slot - no use , tried to change the setting thru Mobile Network but not accessible as it dispays " insert SIM to access the network".... ,, On & off several times - no use, went to Flight mode and back - no use...
Need anyone's guide / suggestions to resolve this issue.
Thanks
Farhan
So, if I understand you correctly, this S4 was an African phone that was powered up in Asia? If correct, then you encountered Samsung's region locking, meaning the device requires a SIM from the appropriate region. Needless to say, you don't have one of those.
This is not a hardware issue, but firmware. Therefore, inserting pieces of paper into the SIM card tray does nothing except waste time and potentially damage the SIM card tray. Airplane mode will not shut the region lock off nor will it deactivate a SIM lock.
To solve this...
1. Purchase an unlock code and type it in to remove the SIM lock. This is also supposed to remove the region locking.
If the unlock code does not remove the region locking, follow these additional steps.
2. Root.
3. Install and run RegionLock Away to remove the region locking.
On the I9505, users could downgrade the modem to an Android 4.2.2 version, root, and then run RegionLock Away to remove both the region lock and the SIM lock, thus completely unlocking the phone. However, you have an I9515, which came with Android 4.4.2 out of the box. Since the I9515 never had an Android 4.2.2 ROM available, RegionLock Away cannot remove the SIM lock, though it can still remove the region lock, which is its intended purpose. This is why you have to purchase an unlock code.

Thank you for your advise. :good:
As you understood that it is belongs to North African & Middle East.
In the phone box there is one sticker pasted which says need to insert the SIM from North Africa or Middle East first to active the phone where the Saudi Arabia also in the list, but now when I inserted the Mobily SIM from KSA, it displays the above message.
So still whether I have to go far a Unlock code or you have additional idea ?

I would buy the unlock code. The unlock code not only will remove the SIM lock, but it should also remove the region lock. As a bonus, you'll increase the S4's resale value, as unlocked devices command a premium over ones that are still locked to their carriers.

I went to a sim unlocking site where it says guaranteed unlocking service if the phone is not Hard Locked. So please tell me how to know my phone is hard locked or not.
For your info. wifi is working in my phone
Also, will you recommend any unlocking service site to try.
Thanks
Farhan
A little searching will do you wonders. I generally point people to sammobile's unlocking service, but if you do a search on Google you'll find hundreds of them.

I am coming back again to this thread after I communicated with a SIM lock Service Provider who clarified many questions and finaly advised me to take the phone to a workshop who can have original SIM and I tried the same but could not find any workshop to help in this regard.
But when I was checking a forum someone asked to check the status of the IMEI CERTIFICATE status by typing *#0011# which I did so and the mobile displayed as IMEI CERTI: FAIL.
I believe here is the problem for not recognizing the SIM . Please need your guide how to solve it.
IMEI certification is a red herring. My device, when it was on Touchwiz, worked perfectly even though the IMEI Certification result was "Fail".

So it is not the case you mean ?
I already flashed the official firmware successfuly and yesterday, I clicked the 'check update' option in the setting and it updated the latest version of the firmware. all options are working except this SIM access.
So do you think any causes like baseband version or modem problem etc.
Nope. I think you have a hardware issue. Especially if you've tried everything software related, including flashing the modem again.
For the same issue, I was in the Sammobile forum where they found my phone is not showing the product code as it says the Product Code: Not Active in the 'Phone Info *SamSung* ' program (CSC page screen shot attached)
Also they told that need to do some work on the nv-data file to restore your Product Code . But when I checked my EFS folder (rooted folder), I could not find this file. I.e. nv_data.bin (see the screen shot of the EFS file folder)
They guided me to follow the steps in this link. http://forum.xda-developers.com/showthread.php?t=780509
but could not continue due to the missing file.
Current situation of my mobile:
- It is rooted with Super SU.
- Took the backup of this folder to my PC but no use due to the above missing file.
- EMEI in the system (*#06#) and written under the batteries are the same. (Not changed)
- All other functions including touch screen, wifi are perfectly working except the recognizing the SIM.
Appreciate your advise
Thanks
nv_data.bin hasn't been present in the EFS folder for some time now. Its information is stored in hidden partitions on the device. Those partitions can be backed up with Wanam's EFS backup tool, but to see what is in them requires you to break open the backup images.
You would be better off getting the S4 looked at, rather than risk bricking the S4 by modifying data in those partitions.
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

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.
