About these guides

PrepaidSIM ranks providers by average per-GB cost for each destination. Prices come from official provider storefronts and update weekly. No provider pays for placement. Overall scores combine Per-GB Rate (40%), Plan Range (20%), Hidden Costs (20%), and Value Retention (20%).
HelloRoam (rated 8.8/10) wins on per-GB cost in the majority of country guides. Nomad (8.6/10) places second on value thanks to aggressive European pricing. Airalo (8.4/10) covers the most destinations at 200+ countries. Holafly (7.9/10) ranks lowest on per-GB value because unlimited daily pricing is expensive relative to metered plans. The cheapest provider changes by destination, so checking the specific guide matters.
PrepaidSIM pulls plan data from 5 providers every week: HelloRoam, Airalo, Holafly, Saily, and Nomad. Price drops and new plans are reflected within 7 days. Each guide shows the current per-GB rate and plan availability for that destination.
Southeast Asian countries like Thailand, Indonesia, and Singapore consistently offer the lowest per-GB rates, often below $0.50/GB. The cheapest provider varies by country. Check the specific country guide for exact current pricing from all 5 providers.
