Vietnamese citizens currently abroad are reporting difficulties accessing the VNeID digital identification system to verify their mobile phone subscriptions. This inability to verify subscription status is raising concerns about potential SIM card deactivation. The issue stems from being physically located outside of Vietnam, preventing access to the necessary verification processes within the VNeID app. Users are seeking clarification on how to maintain active SIM cards while overseas, as current regulations require periodic verification. Authorities have not yet issued a comprehensive response addressing this specific problem for citizens abroad. The situation highlights potential challenges with the nationwide SIM registration mandate and its impact on Vietnamese nationals living or traveling internationally. Further guidance is needed to ensure continued mobile service for overseas users.
