Travel SIM card reviews are all over the internet, and a significant portion of them are affiliate-driven content that lists providers based on commission rates rather than actual experience. We're going to be upfront: we use and earn commissions from Holafly, who we've had an exclusive partnership with since 2024. That said, the reason we chose them for exclusivity was the product's track record across our three-plus years of full-time travel.
Here's a perspective grounded in actual use, not commission schedules.
What makes a travel SIM card actually good?
Before getting into specific providers, it's worth establishing what actually matters. Marketing copy for eSIMs is full of vague claims about "seamless connectivity" and "lightning-fast speeds." What travelers actually care about is simpler: does it work in the places you're going, how fast is setup, what's the data limit, and who do you call when it doesn't work at 11pm in a foreign country.
Coverage in your specific destination, genuine unlimited data (not capped at 1GB with throttled fallback), hotspot capability for when you need to share data with a laptop or tablet, and real 24/7 customer support — that's the actual scorecard.
Holafly: our top-rated provider
Holafly is our exclusive eSIM recommendation. It covers 200+ destinations worldwide, its plans are genuinely unlimited data (with fair use applied to excessive usage rather than hard caps), hotspot is included on most plans, and support is available 24/7 via chat, WhatsApp, and email. We've verified all of these in practice.

With 53,000+ reviews on Trustpilot at 4.6 stars, Holafly has enough data to look past the handful of negative outliers that any large service accumulates. Consistent themes in positive reviews: simple installation, data that actually works on arrival, and support that responds quickly when there are problems. Critical reviews tend to focus on coverage in very remote areas — a limitation shared by every travel eSIM provider, since they depend on local carrier agreements.
Holafly Plans: the monthly subscription model
For frequent travelers, Holafly Plans changes the economics entirely. Instead of buying a new eSIM for each destination, you pay a monthly flat rate that covers 160+ destinations automatically. Light Plan: 25GB for $49.90/month. Unlimited Plan: $64.90/month. The Always On feature connects your phone automatically to local networks in any covered country — the functional equivalent of just landing and having data without doing anything.
