[Help Please!] SIM card issue

Hi,
I am having a strange issue with my SIM card and my S4(9505), I was originally using Vodafone UK but I switched to EE roughly 6 months ago and everything was fine to start with. Then about 3 months ago, the phone would give an error saying SIM card removed and prompt me to restart the device, this would happen about once a day so it wasn't unbearable, however, recently it started giving the same error every 10-20 minutes and now it will not detect my EE SIM at all. The strange thing is, the Vodafone SIM I previously used works perfectly fine. Also, the EE SIM works fine in other devices.
TL;DR:
Phone not detecting EE SIM card but working fine with other networks.
Phone Info
ROM: Omega V40
Android: 4.4.2
Baseband/LTE (Modems): XXUGNG8
Condition: No major drops / damage
What I have tried so far
Replacement SIM from carrier - Same problem
Replacement SIM/SD card reader - Same problem
Taking apart and cleaning whole device with compressed air - No help
Detaching and Reattaching all connectors/ribbon cables on the motherboard - No help
Wipe cache/Dalvik - No help
Wipe data/factory reset - Same issue
Revert to stock ROM - No help
Flash full stock firmwares for EE, Vodafone and unbranded - Same issue with every one, as well as 'android.process.acore has stopped constantly'
Airplane mode trick, as described here(http://forum.xda-developers.com/showthread.php?t=2698621#post58245416) (multiple times) - No help

Anybody have any idea?

I Have the same issue. Its is happening more than once in a day. Drives me crazy.
It started when I installed Omega. So I reverted back to another ROM. I think it is something with the CSC or the baseband.
Anyway, I don't have a solution yet.

[Q] G900F won't make or receive calls

Hi
I have searched the forum beforehand and can't find a post with the same symptoms so...
I have just bought an S5 which will not make or receive calls or texts, although my mobile data works fine!
The guy I bought it from said he had it brand new and sealed, and used a Giff Gaff card for a few hours with no problems before the issue developed. I'm using Virgin. It was apparently from new, a Three network phone but did not appear to be locked to their network.... no unlock messages appeared when my SIM was inserted, it all appeared to work until I tried dialling!
I get a good signal and all the indicators are that the system is connected and functional, but when I dial any number the phone dials briefly then shows "Call ended". Texts just fail after a short while. Emergency calls work OK so the radio seems fine.
From the wonderful Phone Info app the following are installed:
Bootloader version: G900FXXU1BNL9
Baseband version: G900FXXU1BNL9
PDA version G900FXXU1BNL9
CSC version G900FH3G1BNL1
Product code: SM-G900FZBAH3G
I have tried the BOB7 BTU firmware via Odin and this worked ok but didn't fix the problem.
I also tried to downgrade to 4.4.2 with both the Three firmware and the ANG2 BTU firmware. Both just cause the phone to hang at the splash screen.
The serial number, IMEI number and the "refurbishment" check all show the phone as genuine.
Knox is still sitting nicely at 0x0.
Looking through the service menu settings nothing obviously jumps out as a problem but it does seem to be some sort of SIM lock.
Phone info shows the manufacturing date as 2015.01.03 so should be in warranty so I'm holding off rooting it as long as possible
I have scoured the internet and found a couple of others with the same problem but no helpful replies to their queries.
Any ideas anyone? Thanks guys

Try a Giff Gaff SIM in it, if that works, you have your answer

If you have upgraded from 4.4 to 5.09 through Odin as I did with mine which is Generic BTU the phone calls and texts would not work after the update so I did a factory reset then flashed the BTU firmware again did another factory reset and the phone has been fine ever since.
One of my friends got an S5 just before Christmas on 3 Network he was told by them that they no longer sim lock their phones how true this is I don't know but he tells me that's what the sales person told him, but he now has Generic BTU firmware on it not the original 3 firmware, he had to do a factory reset twice before his worked properly
So it may be worth trying bt flashing the BTU firmware again (BOB7) then doing a factory rest, flash the firmware again after that and factory reset once more then see if it works properly

Thanks for the quick replies.
I have flashed the BOB7 and BNL9 firmware several times with factory resets... no difference. I have also tried to downgrade from the original 5.0 to 4.4.2 (UK S5 didn't get 4.4.4 as far as I'm aware) but the phone hangs on the splash screen and I then can't boot into recovery.
I am waiting for a Giff Gaff SIM to try but tried my mate's contract Three SIM yesterday and again data was usable but no phone or texting. In fact it was worse than the Virgin SIM as it displayed no network whereas the all the Virgin info was there as it would be on a working phone.
I originally thought it was a faulty radio but as emergency calls work I have ruled this out.
One thing I've noticed is that in the Service menus there is sometimes the message to "Pease reboot" - an obvious typo but not something I would have thought Samsung would have overlooked. Maybe it's a dodgy clone. Anyway of knowing for sure?
One other thing that may or may not be relevant. In my working phones with the Virgin SIM, the Service menu shows the "Speech Ver" as "FR FR FR" as does the dodgy S5 when it has the Three SIM in it. When I put the Virgin SIM in the phone the "Speech Ver" changes to "AMR, EFR, FR". The "FR" I believe means "Full Range" so is that a contributing factor?
I've attached a screenshot of the phone menu with the Three SIM inserted.
Thanks for your help so far guys, it's much appreciated, this has me stumped.

Thanks for that mate, mine compares ok with yours, particularly the "About" status.
I have now tried 02, Three and Giff Gaff sims as well as my Virgin sim. Same problem, can use mobile data but no calls or texts.
reflashed 3 more times with a factory reset after each, same problem.

No service, emergency calls only after upgrading to android 6.0.1 by OTA

Hi! I have an A5 (SM-A500FU) bought in Italy last year, Im using it since then in Argentina. With android lollipop I have never had issues with lost signal, no service messages or network not available. But since upgrading by OTA to Marshmallow these problems started. I have looked everywhere but I cant find anything that helps me. Also my service problems are not always present, sometimes I do have signal, but mostly when im out in the street. At home, for example I have no service and "only emergency calls" message. I'm using right now and old Moto XT316 with the same SIM card ( Claro AR) im using in the A5, and it is working fine, recieving network signal ( it is also a new sim card, just in case old SIM was the problem). The thing is I can´t use my A5 because it is constantly losing signal.
Thing I have already tried and didn't work:
- Changing to aireplan mode for a few minutes
-take out SIM card, restart the phone, turn off phone, put sim back in again, turn on phone
-verifiyng the APN for my network Claro Ar was correct, manually searching networks ( At home for example, it only finds Personal and Movistar (sometimes) but never finds Claro ar)
-Doing factory reset
-Reinstalling official firmware (PDA version : A500FUXXS1CPH2; CSC version : A500FUVFR1CPG2) with kies3 ( smart switch gave me an error)
-Flashing the UK BTU ROM ( the old one was from Vodafone Italy, now Phone info app says my mobile operator is 72234, while befor was 722310 which is correspondig with claro ar, what does this mean)
what could be causing this problem???? Im really starting to desperate now...
I read something interesting online, searching for some answers I got to the experience of some guy who had a very similar problem. Short story, his had to change his phone's network configuration in the "radioinfo" menu (or whatever the name of that hidden menu is) with an app named Network and force his cellphone to use only 3g or 2g. Turns out that his phone was trying to use LTE but LTE was not available in his region. This solved his problem. Mi phone can't use LTE here in Argentina because it is Italian, and since I have it it never conected to LTE network (I guess we use different frequencies) So I was thinking maybe my phone is also trying to use LTE but since it won't reach 4g signal ends up with no signal at all, excatly like this guy's phone.
But, apparently I need root access to get to this menu or even use this apps, is that correct?
So, should I root my phone to try that? does that story make any sense to you? Any advice?
Downgrade to lollipop I read is not my best option, also rooting it isn´t , but I'm starting to run out of solutions.
I add this information that could be helpfull:
Product Code : SM-A500FZKUBTU
Original CSC code : BTU
Active CSC code : BTU
PDA version : A500FUXXU1CPH3
CSC version : A500FUBTU1CPH1
Baseband version :A500FUXXU1CPH3
Android version : 6.0.1
Build number: MMB29.A500FUXXU1CPH3
Mobile operator :72234
Also IMEI number seems to be fine, it starts with 35 and matches the one in the back of the phone.
Sorry It is such a long thread!! Thank you very much!!

S7Edge "soft bricks" when SIM card is "engaged" (ie, when phone not in Airplane Mode)

S7Edge "soft bricks" when SIM card is "engaged" (ie, when phone not in Airplane Mode)
Hey all... newbie here, so thanks in advance for your wisdom!
I've got an S7 Edge that one day--completely randomly--shut off. It was unresponsive on all buttons until I plugged it in and it revived the charge screen (said 90%). The very odd thing is that the phone would turn on and function as long as there is no SIM card installed or if it is in Airplane Mode--which is frustrating because that means I couldn't make calls or send texts, let alone use mobile data. I have done factory data resets, and had just flashed the newest firmware from SamMobile--still with the same issue (more on that in a second).
This thread from 2016 (https://forum.xda-developers.com/s7-edge/help/s7-edge-shutting-lte-band-t3417691) sounds very similar (phone sounded like mine when LTE was enabled, but otherwise was fine), but now I can't even test it by disabling LTE--if there's no SIM card installed, Android 7.0 makes me install a SIM before I'm allowed to edit the mobile settings; when one is installed & it's in Airplane Mode, it says I have to remove Airplane Mode to edit the settings; if I remove Airplane Mode, the phone crashes as soon as it connects to the mobile network!
Does anyone know if there's been any movement on this since 2016?
Does anyone at least know if there's a way to disable LTE with no SIM card installed?
Phone Deets before Odin nightmare (see below)

*crossing my fingers someone will be my savior!*
["More on that later": I thought maybe trying a different firmware would help (I had tried UK EVR, so I thought another UK version might be better). I flashed a new one using Odin, and now the phone won't even boot past the Samsung logo! I have tried four different firmware's now (UK EVR, H3G, BTU, and a US AT&T version which is for the 935A) and Odin passes every time, but the phone still never boots--even if I use the UK EVR firmware that originally worked!]

[UAE] No Signal in Phone

Hi,
I had updated my S8 device to the newer update G950FXXU1AQJ5 in my device [SM-G950FD]. But after the update, my phone ain't receiving any signal. The phone is detecting sim card and micro SD but ain't getting the mobile network. What to do? I had even flashed firmware again still the problem exists. Please suggest a way to overturn this problem.
P.S.: Sim is of UAE only. Even *#*#4636#*#* is not working.

Hello! I am having the same problem here in Saudi Arabia, it randomly disappears. Did you find a fix?
