Prepaid SIM card registration offers several benefits. Firstly, it enhances security by verifying the identity of SIM card owners, making it harder for criminals to engage in illegal activities using untraceable SIM cards. Secondly, it reduces the potential for crimes like fraud and harassment, as individuals can be held accountable for their actions through their registered SIMs. Additionally, it aids in the recovery of lost or stolen devices by linking them to their rightful owners. Furthermore, it provides consumer protection, ensuring that individuals aren't held liable for unauthorized charges on their SIMs. Lastly, it improves overall service quality, as telecom providers can offer better support and tailor their services when they have accurate customer information through registration.
