Everything you need to know about using an eSIM in Vietnam.
Landing at Noi Bai or Tan Son Nhat, the playbook is the same: queue at a SIM counter, hand over your passport, wait for someone to punch your details into a system, and hope the data plan actually works. eSIM Vietnam skips all of it. You land already connected. Viettel, Mobifone, and Vinaphone are all on the table, with 4G coverage across the country and 5G lighting up in Hanoi and Ho Chi Minh City. No kiosk, no paperwork, no passport photocopy sitting in a database you'll never audit.
For most trips, 3 to 10GB over 7 to 30 days covers navigation, messaging, and the occasional video call home. Short layover? 3GB in a week is plenty. Two weeks island-hopping in Ha Long and Da Nang? Push toward 10GB. ZILLA's plans activate on first connection, not on purchase, so you can buy ahead and burn the clock only when you land.
Every local SIM in Vietnam ties to a passport and a registration form. ZILLA doesn't. Pay with crypto, skip the account, skip the ID, skip the fine print. Your data plan is a QR code and a tap. That's the whole interaction.
No telco knows your name, no counter staff has your document, and nothing follows you home except the signal bars on your phone. No fortress to storm here. Just a QR code and a tap. ZILLA keeps your data on your side of the wall.
