No, you do not! This is a significant convenience and safety benefit with EastESIM. Purchasing a physical local SIM card in Cambodia often involves a mandatory, in-person passport registration process, which can be time-consuming and sometimes bureaucratic. Our EastESIM operates as an international roaming plan, completely bypassing these local registration requirements. You can activate your EastESIM quickly and securely from your device, allowing you to get connected instantly upon arrival in Phnom Penh or Siem Reap without any extra hassle.
