The Vietnam eSIM works across Vietnam, covering popular destinations such as Hanoi, Ho Chi Minh City, Da Nang and Hoi An. It is designed for use within Vietnam only.
The validity of the Vietnam eSIM starts once the plan is activated, not when you buy it. Validity periods of 1, 7, 15, 30 or 180 days then count down from that point.

You can share your Vietnam eSIM connection using your phone's hotspot or tethering feature if your device supports it. Shared data draws from the same allowance as your chosen Vietnam eSIM plan.
When your Vietnam eSIM data runs out, your connection stops until you buy another plan. The Vietnam eSIM is a prepaid, one-off purchase, so you can buy a new plan whenever you need more data.
Yes, your existing phone number stays active for calls and texts while using the Vietnam eSIM. The Vietnam eSIM adds a separate data line, and your primary SIM continues to handle your usual number.

I used Viasimo to travel home to California this year. The instructions were super easy to follow and I had no problems with the service for the whole 20 days that I used it. It was nice not to worry about

Landed in Tokyo, switched off flight mode and I was online before I reached passport control. No SIM-card queues, no surprise bill afterwards.
