Supreme [QUESTION] Advanced SIM Card Communication Exploitation

[15]

? Advanced SIM Card Communication Exploitation ?
Hello, being passionate about the system and networks I try every day to improve and seek to understand. Today, I would like to focus on a slightly technical subject:
I would like to use communication protocols to better exploit the communications of my SIM card, such as unmasking hidden numbers or transferring a call to another telephone number.
So I took the liberty of posting to see if you could help me in my mission. Thank you very much.
I've already done some research on my own and here are the results, hoping that this can help you as much as me:
? My Research Results ?

1. OpenBTS and OpenBSC: These open source projects allow you to create a private GSM network. OpenBTS, for example, can be used to monitor GSM communications by creating a GSM base station. However, setting up such a system requires advanced knowledge of telecom networks and specific hardware such as software defined radios (SDR).
   
2. PBX (Private Branch Exchange): Setting up a PBX like Asterisk on a Linux server can allow some advanced manipulation of incoming calls, although unmasking hidden numbers is rarely possible without operator cooperation.
   
3. Call Redirection with PBX: An open source PBX system such as Asterisk can be configured to handle incoming calls and redirect calls to another number. This requires initial setup on a Linux server and basic knowledge of IP telephony.
   

If anyone has additional insights or can offer guidance on this topic, your help would be greatly appreciated. Let's collaborate and push the boundaries of what we can achieve together!
