Which eSIM is best and cheapest for Indian students?

The 'best' and 'cheapest' eSIM depends on your destination and data needs. The most cost-effective option is usually a long-term plan (90+ days) with a generous data allowance (20GB+ per month). For students in Europe, a regional eSIM is often the cheapest as it covers multiple countries. For the US or UK, look for country-specific plans that partner with top-tier local networks for reliable coverage.
