IMEI blocking

**IMEI Blocking**

IMEI blocking is a security feature used to prevent stolen or lost mobile devices from accessing cellular networks. By blacklisting the device’s unique International Mobile Equipment Identity (IMEI) number, carriers can effectively disable the phone, making it unusable for calls, texts, or data services. This helps reduce mobile phone theft and protects user privacy. IMEI blocking is commonly implemented by network operators, law enforcement agencies, and device manufacturers to ensure lost or stolen devices cannot be easily reused or resold.
