No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

No, this is a common trap for travelers to Vietnam. As an independent country, Vietnam is not part of any 'free roaming' agreements typically offered by US, UK, or Canadian domestic plans. Using your home SIM from providers like Verizon, O2, or Rogers will likely result in very expensive international roaming charges. EastESIM provides a much more cost-effective and reliable solution, connecting you directly to strong local networks such as Viettel or Mobifone, ensuring you stay connected affordably whether you're in Ho Chi Minh City or exploring Ha Long Bay.

Enjoy consistent, high-speed internet wherever your Thai adventures take you.
