Case Study: Saving Money & Time with Vietnam eSIM Data Plans
Case: Alex, a student from Germany, planned a three-week motorbike trip from Ho Chi Minh City to Hanoi. He compared Pocket WiFi rental (~$3.5/day), physical SIM (~$10 plus registration), and eSIM data plans (7GB/15 days ~$10, instant delivery).
- Pocket WiFi: Expensive, needed to be picked up/returned, shared data meant slow speeds in the countryside.
- Physical SIM: Registration at airport shops was slow, and some required a local address or passport scan.
- eSIM Data Plan: Bought online from GoVnSIM in 3 minutes, instant QR delivery, worked everywhere—even in remote areas.
Result: Alex saved ~$25, never lost connectivity, and used his eSIM as backup in Laos and Cambodia too.
