Hi!
So I have this problem with my Samsung Galaxy SII that it doesn't recognize the SIM card for the most of the time. When this problem started, the phone was completely stock (Not rooted/Not a single flashing made by me). Android version was the latest official 4.1.2.
Problem description:
I could be using the phone completely normally and then suddenly it reports that there is no SIM card. Now with pulling out and putting back the SIM card and rebooting couple of times, it might recognize the SIM card again and work for a while (few hours).
What I've tried to fix this:
1. Tried the SIM card on another phone, it worked perfectly.
2. Tried another SIM card on my S2, didn't work any better.
3. I thought that as the warranty is over, I might aswell just root my S2 and install the CyanogenMod 12.1 and check if this fixes the problem (Well it didn't).
4. I saw that my IMEI number shows nothing so I did this: [GUIDE] Recover your IMEI in 9 steps..
Well step 4 didn't bring back the IMEI number but now after rebooting a couple of times when I got my SIM card to be recognized again and then checked the IMEI, it was correct. Though the SIM card wasn't detected after a while again.5. Well now I flashed back the original Android 4.1.2 and checked the IMEI number (SIM not detected), it showed "null/null".
6. I went back to CyanogenMod 12.1 and saw that when it's showing blank IMEI, it's also showing "Baseband version: Unknown.
7. Flashed a new Modem+RIL, not helping either.
8. Tried many other things which I can't remember now but found by googling.
So it's sometimes working and also shows the correct IMEI and baseband and sometimes they are all gone?
My question here is that is there anything I can still try to get it working. And also if anyone knows where the problem could be? Is it some part that is faulty or is it the software that is messing with me? I'm quite handy at taking apart and changing the parts inside if that is the case. It's just that I'm not going to pay over 100€ for a new motherboard to get it fixed.
Thanks for any replies!
During the writing of this message, I took the pictures which I attached to this message.
So I have my i9300 for a couple of years now and everything worked fine until I moved to Germany a couple of weeks ago (I come from Bosnia and Herzegowina). The phone was bought in Bosnia and I have a SIM card from the bosnian telecom (BH-Telecom) which worked fine. Then I bought a SIM card here (congstar) and my phone couldn't use it because of the network SIM prompt. I realised that that feature was kind of "blocked" (sorry but it's the first time I'm doing this) so I had to unlock it. I tried installing various versions of stock ROMs (including all German) via Odin on my phone, but everything stayed the same. I found this app:
play.google.com/store/apps/details?id=com.spocky.galaxsimunlock
But it said that I had to root the phone and after I did that also to change my IMEI which changed during the hole operation. Fortunately, I wrote it down before. But I can't change this "new" one to the old in order to get the "simunlock" app working. I used:
play.google.com/store/apps/details?id=com.vivek.imeichanger
and
play.google.com/store/apps/details?id=com.phoneinfo.changer
But after I write down my old IMEI and click Apply I reset the phone (as the popup says in both apps) and type *#06# the IMEI stays the same. Not only there, but in all other apps that I used. And well, my old SIM doesn't work either. My phone shows that "blocked SIM" icon for both SIMs.
Please, for the love of God someone help to at least make my old SIM working. Unlocking my phone completely would be amazing.
Help
Firstly, you cannot unlock it if it has ever been on 4.2 or higher. The old method was nvdata edit but it is obsolete on updated phones.
The quickest cheapest way is to take it to a phone shop and pay.
You need to be on the stock rom that came with the device from factory.

But I can get my old SIM working ?
I received my new Redmi 3S yesterday. It can send and receive SMS, internet is working, it identifies the SIM, the carrier and the number. But it doesn't make or receive phone calls and calling settings/features cannot be accessed.
I tried a factory reset, removed the SIM and reinstalled it a couple of times. Phone is not rooted, bootloader is locked, ROM is MIUI Global 7.3 STABLE | 7.3.10.0.0 (MALCNDE). Any help appreciated
Edit: I should mention that I tried more than one sim cards that function properly on a another device I have
edit 2 : Here is the problem http://i64.tinypic.com/xeq68y.jpg
I discovered that I am able to make calls from SIM 2 slot (nano SIM / SD card) but not from SIM 1 (micro SIM). Any idea why? Anyone? The big deal is that by using SIM 2 slot I am not able to use my SD card

why dont you try to flash a stock rom with full wipes and see if that solves your problem of making/receiving calls.
Thanks. I will give it a go. I really don't want to send my newly arrived phone back to China
Installed stable Chinese 7.5 ROM and the problem still persists. After all the effort I just noticed that under settings>>>status>>>SIM status there are two differences between SIM 1 and SIM 2. 1 has cellular network type LTE, 2 has GSM (both SIM cards are LTE). 1 has IMEI SV unknown, 2 has 01. I suspect the lack of IMEI SV number is the reason why SIM 1 cannot make/receive calls. Both SIM slots have an IMEI number. So now I need to find a way to root ( I am having some trouble there too) and inspect further.
Help!!!!!!
I really need some help now.
1. I was trying to unlock bootloader but always got stuck at 50%. Nevertheless, in cmd*"fastboot oem device-info"*the bootloader appears to be unlocked but security app/permissions/root says it is locked. Now even flash unlock utility says "no need to unlock device" when stops at 50%. Which one is telling the truth?
2. Tried to flash twrp, followed the procedure to the letter, the utility told me that the flash was successful. But when I reboot to recovery all I see is the white outline of a device, no TWRP
3. SIM 1 can send/receive texts and connects to internet but no incoming/outgoing calls. SIM 2 working fine
4. Mi PC Suite does not recognise the device
I've bought Chinese phones before but this one is just too much work..
Did you use mi unlocker tool?
Did you allow oem unlock on developer options?
You have to login with your mi id both on your phone and that tool.
Once unlocked, follow these instructions for TWRP http://forum.xda-developers.com/redmi-3/development/redmi-3s-land-twrp-recovery-unlocked-t3433199
Sent from my ehmm... well... phone with xdw... cda... err... well I sent it, okay?
Yes. I have use mi unlock tool and followed the proper procedure. I will try the above method on Sunday, when I have free time, and fingers crossed..
Regarding your sim problems...
In settings > about phone: press 'internal memory' a number of times to get the hidden menu. 'Phone information1' refers to sim 1 and you can change network types etc.

I tried all the settings one by one but nothing has changed. Finally I managed to unlock bootloader and root but the no calls problem from SIM 1 persists. I found this http://en.miui.com/thread-245598-1-1.html for IMEI repair, I would like to repair the IMEI SV in similar way. If someone can help with this or has any idea why SIM 1 sendss/receives texts and connects to internet but doesn't make/receive any calls I will be much obliged.
So basically this is the problem

That's interesting. So maybe the problem is not with the IMEI SV number. It may as well be a hardware problem. I don't think you have something to worry about. Thanks for letting me know though

whether it's work for both sim? why i cant.. :crying::crying:
Sorry haven't solved the problem. I got a partial refund and only using one SIM slot
My phone's SIM card is not working as expected:
- it is recognized (The phone asks me for the password when he detects the SIM card and code is accepted)
- it says "No service" and of course, I do not get any services (no phone calls, SMS or data)
My history on this device so far (in case it matters):
- This SIM card worked when I received the phone from gearbest (and I upgraded to latest MIUI 8.0.5) and I could make a test call and send/receive SMS.
- Then I wanted to install CM13, I had to go to the unlocking procedure that didn't work as expected and required me to install Global Dev Roms (and this didn't work as expected) so I finished by flashing nearly all of the ROMs (Global, Global dev, China, china dev) using EDL mode. Quite quickly I notice that I lost functionalities upon the simcard : on some ROMs it would not even been seen (no sim card displayed, nor Wifi).
- I had to resort to a bootloader hack to reach unlocked state because official way did not work at all (blocked at 50%). And got on my way to install CM13... most ROMs would have the exact same problem than the official images: no sim card detected (and no Wifi neither BTW).
- It is only on the very latest ROMs for kenzo CM13, (> 2016-10) that I got back Wifi and sim card detection. Unfortunately, the sim card is still in Emergency mode and states "No Service"
- I flashed many NON-HLOS.bin with TWRP without seeing any changes (7.1.7 and 7.1.8 for the latest), but would be happy to get a link to the latest ones to continue trying.
- flashing the radio.zip mentionned in many comments breaks back to the "no Wifi and no SIM card detected" state, hopefully re-flashing NON-HLOS.bin 7.1.8 has re-enable previous better but incomplete state.
More raw info:
- the sim card is valid: it works in another phone straight away
- the antenna cable seems securely fastened (I opened the phone just to check this)
- I still have an IMEI when dialing *#06#, and it matches the number written on the sticker inside the phone.
- it behaves strangely when using the test interface *#*#4636#*#* : no network is displayed, has network type of "LTE/GSM auto (PRL)" that I can't change despite the many other choices listed in the menu. I can't also turn on radio signal.
Any help/suggestions to get back my 3G/4G SIM card services ?
==== THE ANSWER ===
Thanks to @corkiejp:
I don't have Kenzo (Standard Chinese Redmi Note 3 Pro) architecture but Kate (International Redmi Note 3 Special Edition).
How to check your version.
I needed only to flash the correct KATE radio firmware to sort it out.
Flash correct fastboot rom for your device again
@vaab69 Are you sure you have the "Kenzo" version? Maybe you got the "Kate" model and are flashing the wrong roms for your device.
Telling the Redmi Note 3 Pro (Kenzo) and Special Edition (Kate) apart!

Can you be more precise ? What is "correct" fastboot rom ? I have many of them, and already flashed all of the official ones (stables and dev, global and chinese, MIUI) and that didn't bring my SIM services back.

Wow, thanks, this was it ! I spent a lot of time on this skimming through many places. Dunno how I have not came across this !
I just applied the kate radios, and Tada ! it worked.
More info BTW for any other guy stumbling on this thread and wanting to get straight with KATE:

Is there any special things to do on the thread to mark it resolved, or to thank you ?

Hi;
I received Xiaomi Redmi 6A from a week but when I install 2 sim cards, the sim card in slot #1 work fine all the time BUT the problem is with slot #2 the sim card not activated and work by it self for maybe a minute and then turn off again.
When I tried to swap the sim cards to check if the sim works or not it works in slot #1 and the swapped sim from slot 1 doesn't work in slot#2.
this problem is not with my device only my friends got the same device and they have the same problem as well.
I searched the web for solution and found people talking about " Find My Device " turn it off and other methods, I followed all of them but still the same.
I hope you can help with this issue, thank you all.
