For students abroad, eSIM coupons from providers like Airalo (offering 15-20% discounts) and Jetpac provide affordable international data to stay connected for studies and travel . However, before traveling overseas for academic purposes, Filipino students must secure their legal identity documents first, especially the NBI clearance which serves as a nationwide criminal record check valid for one year from issuance . Whether applying for a student visa abroad or preparing for overseas employment, complete your NBI clearance online if yours was issued after 2014, or visit any NBI branch with two valid IDs and photos to avoid processing delays of 2-6 weeks
