Drift Asia helps travellers choose mobile data across Asia. It publishes eSIM plans, local operators, field tests and planning tools for destinations across the region. Each plan shows its data allowance, validity and price before purchase. Available plans are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
