No sim inserted!

Okay so basically, I bought an S4 from local ads, unlocked it via a service i paid for as the free one on here didn't work (couldn't access service mode).
Entered given code, unlocked fine, was using it for about 1 hour and then it said something along the lines of "sim card removed, mobile data will not be used until valid sim is inserted".
Now it shows that there is no sim inserted even if there is.
I've tried multiple sims, including the original network it was locked to, still no sim stated.
I've tried flashing a lower modem in Odin, i've tried flashing the latest ROM in odin, (all official).
I have now run out of ideas! I phoned samsung support and they didnt do any troubleshooting and said it needs to be booked in for repair, im pretty gutted as i'm without the phone for that... Was just wondering if its a common fault? and any easy way to fix it.
Thanks in advance!

[Q] Voice: out of service. S5-G900F

someone save me please... I've been struggle for two weeks...
I'm using S5-G900F, its a Hongkong version, and I'm currently in UK with giffgaff. last month I tried few new rom and then I can't use voice service any more. However I still have internet. Some detail below:
APN
1. I 100% sure its not an APN problem
IMEI
1. IMEI seems ok, start 4 digit 3524****
SIM card related
1. At first I assume it's a SIM card related problem, I tried 2 SIM with different ISP, neither work.
2. Also, I put those 2 SIM on my iphone4 to verify that the SIM is good, and both card work.
3. I also checked the SIM card cable, I put one piece of paper above the SIM to tight the contact, still doesn't work.
Phone related
1. Before I brought the phone, I had check the bands it supports, and it is capable to used here. And the phone work perfect (well, with stock firmware its really slow) before everything happen.
2. Since I brought this phone in HK and now I'm in UK, I tried to flash both latest UK and HK firmware (lollipop), neither work.
3. I also tried only flash baseband from that two firmware plus one old-version baseband. none work.
4. For those flash mentioned above, I do full wipe.
Rom
The rom I tried list below (in time sequence)
1. XtreStoLite (the BL/baseband is extract from Brazil stock firmware. After that problem occur, but I didn't realize)
2. CM12 (this two are all from this forum)
3. TGY-G900FZHU1BOA1-20150120092320 (HK stock firmware, 5.0. Try to recovery the voice)
4. BTU-G900FXXU1BOB7-20150223084756 (UK stock firmware, 5.0. Still trying)
5. Also 2 baseband/BL from XtreStoLite thread (Another is an old-version. Still).
So now for everyday, I had to carry two phone... one just to make sure I don miss any call.... I have tried and still no clue... really need some help here.... Help please...

Can anyone help me please....

Was the phone service working for you before you tried a new ROM?
I have the same issue. Can't make or recieve calls. Internet is working though.
When you try to call someone, do you get 'call ended' message almost immediately after dialing out?
Also, when you go to phone / settings / additional settings (or more settings) - does the 'network or sim card error' pop up?
Can't figure this out... Hopefully someone would be able to point us to right direction, other than to replace it
And of course I did a factory reset, new roms, modems, everything there is to try. nothing helped

could it be because of Region Locking? Maybe it's locked again after flashing?. I want to buy this phone but I am not sure if it will get region locked again after it gets updated or custom flashed.

Yes, before I flash those ROM everything goes well. I'm currently using CM12 so I don't have the setting you mention. But anyway I never seen that pop message before. I guess the SIM card work good as the phone can connect to the internet (not wifi, cellular internet).

SIM not recognized in S4 GT-I9515 (Not Registered on Newtork)

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 ?
Regards,
Farhan

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.

Problem with the apn setting

Recently unlocked my Samsung Galaxy s7 edge. I decided to transfer my sim from my iPhone to my Samsung. I can text and call but my mobile data is not working. I believe it has something to do with my apn settings. But once I try to go to my apn settings it says "Unable to view access point name. Access is restricted to current user profile.
Would love to have someone to help me fix this problem.

What carrier is your s7

Globe (from the Philippines) gotnit unlocked and moved to Canada and using a Canadian sim atm

Sounds like a common problem going back to the introduction of mm. Carries implemented it to stop users from getting free Hotspot usage without them having the feature on there plans.
http://forum.xda-developers.com/galaxy-s6/help/apn-settings-t3072391
Here's some info I found on it with a possible fix on one of the post. Also the sprint s7e forum has users talking about losing the ability to change apn after OTAs

Sorry my Internet is dreadfully slow and having a hard time browsing through this forum. So do I have to root my phone in order to make the modifications to get my 3g to work?

Still having problems but I'm getting somewhere..
The carrier I bought this phone from did some retarded modifications to this phone.
So most likely the problem is this "user profile" it might be fixed if I can change or delete it or whatever. But the problem is I can't find the place where you can change this user profile. It seems it's supposed to be in "about device" but there is nothing that could change the user profile. I think the previous carrier somehow modified it stupidly. Reformatting doesn't help BTW.

I have the same problem. Did you get this fixed?

Globe-locked S7 unlocked.
Same thing here. I just recently unlock my phone using the unlock code given to me by Globe telecom but when I use different sim network, I can only do call & text. I contacted Globe and the agent told me that unlocking is for call & text only and mobile data still locked to Globe.
Can we bypass this by reflashing openline firmware or wait for Oreo update?

After the Oreo update, I still have same issue. But before I upgraded to Oreo, I managed to fix the issue. I was trying to root my device (Nougat), unfortunately, it failed. So I downloaded openline firmware (PH version) for S7 in Sammobile and reflashed. I think I missed flashing CSC file but it was successful. The other sim network worked fine and can be used for data already. But when I checked for OS updates, it has no CSC code indicated, and my settings interface was like from UK (not sure). So I reflashed again with CSC file already and it got back to Globe interface and same issue occured. Haha. But the point is, we can fix the issue by changing CSC.

Great mate! What csc can we use? Thanks!

CSC Codes
Google the list of CSC codes per country.
To change CSC code, enter *#272*Device IMEI#
Tried XTC (Philippines - Open Line) and it worked.

S7 Edge (SM-G935F Exynos) Carrier Flash ROM Question

Hey guys, i was wondering if i can flash firmware from other carrier without bricking?
I bought my phone last year locked to carrier, and I unlocked it using doctorSIM service. Phone itself works fine, and as I'm not living in country that i bought my phone from originally, phone gives a message "No SIM card installed" sometimes once a week, sometimes several times a day and i need to remove SIM card or to restart phone to make SIM card work again.
Please note:
- SIM Card from my original carrier (from one that I bought my phone from) works PERFECTLY fine
- My other SIM card (that my phone constantly rejects) works in other phones just fine
- I have tried to reset the phone, and carrier bloatware constantly keeps installing
- EDIT: Wi-Fi and 4G are working PERFECTLY fine
What to do? Any ideas?
Thanks in advance and sorry for gramar mistakes

Bump, flashed other carrier firmware, still same problem.

R u rooted? Have you considered flashing a CSC packet for your location?
I have a 930S, and works fine with the Korean ROM/Chinese language here in the US, on ATT service.
I have flashed the ATT, XAA and TMB CSC sets, and though the phone worked, and loaded the correct USA carrier info, I lost the phone code ability, which I could not solve.
In the end I went back to the original Korean ROM and it's CSC packet. Interestingly, though it works perfectly here in the U.S., and I can use/input phone codes, it still shows Chinese cities for my 'Region", none of which I have selected. When I do a search for local towers, it locates and correctly identifies AT&T, T-Mobile, etc. I select ATT. The Chinese cities remain in the region selection, none selected.
Wait and see if someone knows if CSC (Exynos or US based CPU) are interchangeable. I used CSC packets from a universal ROM setup (non-USA).

I'm not rooted, as I use Samsung Pay and have more than one year of warranty left. I will try flashing CSC of the current country I'm in (Austria). Thanks for taking time and writing all this, this problem is unbearable

Hello!
My s7 edge is in trouble, it freezes sometimes, and sometimes it gets a full screen of pixel color flaws, with that problem my root smartphone works two weeks. Sometimes this error occurs in the ROM installation process, I insist on the installation until I can. I tried to install superman rom and due to this problem, the smartphone in the screen of death "exception of bootloader" (But it's already been resolved)...
When searching the internet, I saw that this could have a problem in flash memory.
After all history, I ask;
I could use a twrp file system repair function to try to solve this problem? And how to proceed?
(sorry for the use of google translate)

I am, by far, not educated up on TWRP, so I'm not sure what you mean by "repair", other than making sure your data partition is formatted so it does not cause the issues you are talking about.
Here is an interesting read:
