FAQs
Does eSIM coverage reach Sapa and Ha Long?
On Viettel-hosted plans, Sapa town, the Ha Long cruise area and the Hai Van Pass are well covered. Cable-car summits and deep valleys still have gaps — fine for messaging, not for streaming.
Can I buy a Vietnamese eSIM without registration?
International travel-eSIM brands pre-register their pool SIMs, so you don't submit anything yourself. Buying locally at an airport counter means showing your passport there.
