- If you are an expat, digital nomad, or long-stay traveler, consider Vinaphone eSIM plans for long-term value, stability, and local support. Vinaphone is preferred by many expats living in major cities and those who need stable service for banking and residency paperwork.
- Always get your eSIM before you fly. Online purchase means you’ll receive your QR code by email, ready to scan on arrival.
- For Grab, Zalo, or banking OTP, only eSIMs with a Vietnamese number (like GovnSIM, Mobifone, or Vinaphone) will let you receive local SMS/calls.
- Save your QR code in the cloud or your email—you might need it again if you reset your phone.
