Do I need a passport or local ID to register this EastESIM for use in Thailand?

No, that's one of the significant advantages of choosing EastESIM for your trip to Thailand! Unlike purchasing a physical local SIM card at Bangkok (BKK) or Chiang Mai (CNX) airports, which often requires presenting your passport for a mandatory, time-consuming registration process with the Thai authorities, EastESIM is completely digital. You can activate it seamlessly before you even arrive, bypassing any queues or bureaucratic hurdles. Enjoy instant connectivity upon landing, allowing you to focus on exploring the vibrant markets of Bangkok or the serene temples of Chiang Rai without delay.
