The Pakistan Telecommunication Authority (PTA) has issued stern warnings concerning the use of unregistered and foreign SIM cards, as well as the dissemination of illegal online content, highlighting significant risks to personal data security and legal implications. According to TechJuice, the PTA's advisory emphasizes the growing threats of 'fraud, data theft, and legal trouble' associated with unregistered SIMs, urging citizens to purchase SIM cards from authorized outlets. ARY News further elaborates that using foreign SIM cards can 'compromise your personal and financial data' and lead to 'legal complications.' This warning is part of a broader strategy to enhance digital security as Pakistan's telecom sector expands, making it a 'critical national concern.'
