Local tips for travelers
- Install the eSIM before departure when you have stable Wi-Fi, but follow the selected plan’s activation rule before turning it on.
- Your phone must support eSIM and be carrier-unlocked. Model support can vary by country of purchase.
- Turn on the eSIM line and data roaming after arrival if the plan requires roaming to connect.
- Do not delete an installed eSIM unless support confirms that it can be reissued.
Best season: Vietnam is a year-round destination; weather varies significantly between the north, central region and south.
