Five providers. Five categories. Every award is earned through our five-criteria scoring system, tested with purchased plans on real devices across 200+ countries. No provider can buy a better score.
HelloRoam scores 9.5/10 in our 2026 testing, our highest-scoring provider of the year. It reaches 186 countries through 204+ carrier partnerships, offers fixed data and unlimited daily plans, and supports 31+ currencies with localized pricing. The coverage-to-value ratio is the strongest in the category.
Airalo earns Best Overall for the widest coverage (200+ countries), the most polished app in the category, multi-country regional bundles that no competitor matches, and Airmoney cashback rewards that lower the effective cost for repeat buyers. It is the provider we recommend to the most travelers.
Holafly earns Best Unlimited for its unlimited daily data model. Pay per day, use as much data as you want. Combined with 24/7 live chat, a 6-month refund policy, and 178-country coverage, it is the clear pick for heavy data users, remote workers and streamers.
Saily earns Best Privacy because every plan includes VPN protection from Nord Security, the company behind NordVPN. For travelers visiting countries with restricted internet access or anyone who values encrypted browsing on public networks, Saily is the only provider that solves connectivity and privacy in one product.
Nomad earns Best Budget for the lowest per-gigabyte pricing we measured, particularly strong in Southeast Asia and other popular backpacker destinations. The app is basic, support is email-only, but the savings are real and the connection is reliable.
Every provider is scored across five weighted criteria: coverage breadth, price per GB, connection speed, app quality, and customer support. We buy every plan with our own money. No provider sends complimentary access or pays for placement. The provider with the highest weighted score in each category wins the award.
Our buying guide takes you from “what is an eSIM?” to a confident pick in five minutes.
