What is the free eSIM offer in the e-visa approval email and is it real?

We cannot confirm that offer. The approval email from the government portal is an automated message with your visa details, and you should treat any extra links or promotions in it, or in similar emails, with caution.

Check the sender, and do not enter payment or passport details on a site you reached by an email link. If the offer is real, it should be easy to verify on the provider's own website. A genuine free trial usually asks for little more than an email address.

If you want a data plan, buying an eSIM from a known provider before you fly, or a physical SIM at the airport, is straightforward. Our Vietnam travel guide has tips on connecting on arrival.

Your visa itself should be downloaded from the portal or the email of the service you used. You can look it up on evisa.gov.vn to be sure it is genuine.
