eSIM Rankings for South Asia (8 Countries)

Our South Asia rankings are built on a single objective metric: cheapest cost per gigabyte ($/GB) available from each provider for that country. We pull live plan data weekly from Airalo, Holafly, HelloRoam, Saily, and Nomad, record each provider's lowest $/GB for a given destination, then rank countries within South Asia from cheapest to most expensive. No sponsored placements, no subjective scoring — only verified price data determines position.

Provider leadership varies by country across South Asia's 8 destinations. In our rankings, the top-ranked provider for any destination is whichever of the five tracked providers (Airalo, Holafly, HelloRoam, Saily, Nomad) offers the lowest $/GB that week. The overall South Asia region average sits at $3.10/GB, with Bangladesh currently setting the regional benchmark at $1.25/GB. Visit individual country ranking pages to see the head-to-head provider breakdown per destination.

Based on our scoring methodology, South Asia eSIM prices span from $1.25/GB in Bangladesh up to $7.81/GB in Maldives — a 6.2x spread across the region. The regional average of $3.10/GB is a useful benchmark: destinations ranking below it represent strong-value picks, while those above warrant closer provider comparison before purchasing.

In our rankings, $/GB is the primary factor because it normalises across different plan sizes and durations, making cross-provider comparisons fair. Secondary factors visible on each country's ranking page include total plan count (more options signal a competitive market), network speed tier (4G LTE vs 5G), and the spread between the cheapest and most expensive provider. For a South Asia trip covering multiple destinations, check whether any provider ranks in the top position across all your stops — that consistency often beats switching providers per country.
