Holafly review

Holafly ranks fourth because it is the simplest way to stop counting gigabytes. Its App Store listing says Holafly sells unlimited data plans in 200+ destinations, including Europe, Mexico, China, Turkey, Japan and the USA, with limited data plans and top-ups elsewhere. Holafly's Japan page lists unlimited plans in USD at $11.90 for 3 days, $27.50 for 7 days and $73.90 for 30 days. The eSIM arrives by email within seconds, installs with one button on iOS 17.4 and later, and data starts only once you reach the destination. The limits matter for price per gigabyte: light users pay more than they would on a small fixed plan, and the Japan page caps hotspot sharing at 1 GB of shareable data per day. Payment works with Apple Pay, credit card or PayPal. We compared documented features and published prices; we did not test networks abroad.
