Nesa

Nesa positions itself as the budget eSIM choice, pricing its Japan 20GB plan at just $11 (roughly $0.55 per gigabyte). The service covers essentials without unnecessary frills and keeps costs low through lean operations.

Nesa fits travelers on tight budgets or those who use data sparingly throughout their trip. While its Trustpilot presence remains limited with only 16 reviews so far, the pricing is genuinely competitive for basic coverage in Japan.
