eSIM Vietnam: Prepaid Plans from $4.43

Activate your Vietnam eSIM at home before heading to the airport. Open Settings on your iPhone or Android, tap Add eSIM, and scan the QR code from your HelloRoam email. The process takes under 2 minutes. Your e SIM connects to a local network the moment your plane lands. No hunting for a SIM kiosk at JFK, LAX, or SFO. No SIM card swap needed.

HelloRoam offers a 180-day refund window on all eSIM plans, processed back to your original USD payment method. If your trip changes and you have not installed or activated your e-sim, you get a full refund. If you used some data, HelloRoam refunds the unused portion. Contact support with your order ID within 180 days. Refunds process in 5 to 14 business days to your US bank or card. HelloRoam's 180-day window is longer than Airalo and most competitors.

HelloRoam eSIM works on any carrier-unlocked phone, including phones originally on T-Mobile or Verizon. If your phone is paid off and unlocked, scan the QR code in Settings to add HelloRoam as a second line. Your T-Mobile or Verizon number stays active for calls and texts while HelloRoam handles data in Vietnam. Phones still on a carrier payment plan may require unlocking first. Complies with US CCPA data privacy rules. Does not sell personal data.
