What do USSD codes mean?The term USSD stands for Unstructured Supplementary Service Data. While the full form of the acronym might sound very complicated for you, it is not. It is sometimes even known by other names, such as feature codes or quick codes. To put it in simple language, USSD is a set of unique codes which are considered as communications protocol. The set of unique codes are used by your GSM telephone operators. Moreover, you can use these codes to interact with the computers of your telephone service provider.
When you type in an USSD code, you are asking for a specific set of information. Accordingly, the servers get back to you with the information that you requested. Usually, these codes are programmed into your mobile number or your SIM card.
The term IMEI means International Mobile Station Equipment Identity. Every smartphone in the world is assigned a unique IMEI number. Hence, it provides a unique identity to your smartphone. With IMEI, you can track down phone numbers, which can be helpful when your phone has been stolen or lost. In addition, you can also use IMEI number when you wish to resell your smartphone.
I would like to start by mentioning that what I'm trying to achieve is to be used only on those devices which are distributed by us and we have complete ownership on these devices and the applications which run on these devices.
My requirement is to enable "Lock SIM card" under Settings -> Security -> SIM Card Lock Settings on android phones and set/change the SIM lock/unlock pin. All the phones are rooted and are at remote locations. I don't have physical access to these devices but I have remote access to ADB shell.
I monitored the logcat output while trying to enable the "Lock SIM card" checkbox manually for pointers on which service is being called and figured out is the task is handled by the method com.android.internal.telephony.IccCard.setIccLockEnabled which is not exposed through SDK.
I am stuck there. Is there any way (USSD/programmatically using reflection/adb shell command) by which I can enable the "Lock SIM card" setting (automatically accepting the popup it shows/disabling the popup if possible) and then set/reset the pin.
Seeing that it has been 3 months with no answers, I could propose a suggestion. Enabling and managing the PIN is a SIM feature. You could write application code to send "RAW" data to the SIM directly. This data would be in the form of APDU's defined in ISO-7816-4 document. Look at VERIFY, CHANGE REF DATA, ENABLE/DISABLE VERIFY commands. Alternatively make reference to GSM11.11 VERIFY/CHANGE/ENABLE/DISABLE CHV Commands.
Airtel PUK code is a security wall that restricts access to SIM cards by other users. PUK code, also known as Personal Unblocking Number, is a code that is used to unlock a SIM card after you have locked it by attempting to enter the PIN three times.
PUK code is specific for each telecom operator and Airtel has its own. The PUK code for an Airtel SIM card is known as the Airtel PUK code. It is written on the SIM card or on the SIM envelope that is provided while handing out the SIM card.
You can also go authorised Airtel store to unblock your Airtel SIM card. The customer care representative might ask for a few details in order to verify whether the number belongs to you or not. Once verified, the representative will help you to unblock your Airtel PUK code.
Every Nigerian citizen must possess a unique number called National Identification Number(NIN). Despite the World Bank's ID4D initiative aiming to increase NIN registrations to 148 million by June 2024, many Nigerians still have not gotten their NIN.
Recently, users have reported their SIMs being barred from making outgoing calls even after linking their NIN, this is likely due to the Nigerian Communications Commission's (NCC) new measure which mandates telecom operators to block any SIM not registered with a NIN by February 28, 2024.
A National Identical Number (NIN) is an 11-digit non-intelligible number assigned to Nigerian citizens and legal residents at the National Identity Management Commission (NIMC) once enrolled in the National Identity database.
Your NIN matters in several ways: it facilitates secure identity verification across various sectors, connects personal records, and ensures smooth access to services like bank accounts, mobile numbers, and government benefits. It also strengthens fraud prevention and boosts government efficiency, streamlining interactions and reducing unnecessary hurdles.
To link your NIN to your sim, you need to know what your 11-digit identifier is. If you do not know your NIN, you can retrieve it by visiting any NIMC office near you. You can also retrieve it manually on your phone by dialing *346#. This is effective for all the major network providers in Nigeria - MTN, Glo, Airtel, and 9Mobile.
Interestingly, NIMC has made us understand that there are two types of NINs: NIMC-generated NIN and BVN-generated NINs. If you are among those who already have the NIN that your bank generated during the BVN registration exercise, here is what you need to do:
The commission said recently that Subscriber Identification Modules would not be linked with National Identity Numbers generated through Bank Verification Numbers. It also called on the affected individuals with BVN-generated NINs to visit NIMC offices to validate their NINs, stating that BVN-generated NIN would not work on its newly inaugurated NIMC mobile app.
Note: The NIN validation code above only works for SIM cards that have already been registered and previously linked with a NIN. You also have the option to print out your NIN slip if you have any need for it.

Open the Quick Settings menu and tap on the Power icon. Then, tap and hold Power off until you see the Safe mode icon. Tap it to restart your phone in safe mode.
If you still can't get MMI codes to work, consider resetting your Android phone's network settings. However, you should know that resetting your network settings will remove paired devices, data limits, and Wi-Fi passwords, among other network values.
MMI codes can be very useful, especially if you have to service your phone and need software and hardware information. Now, if you still can't get MMI codes to work, you'll need to contact your network provider for carrier-specific instructions. There's a good chance your carrier will offer you a new SIM card.
