Most travel eSIMs give you a data cap — 3GB, 5GB, 10GB — and then you're either throttled or cut off. Yesim is different: they offer genuinely unlimited data plans in 100+ countries, making them the go-to choice for heavy data users, content creators, and anyone who can't afford to run out of data at a critical moment. We tested Yesim across 8 countries for this review.
What Makes Yesim Different: Unlimited Data
Yesim's key differentiator is their unlimited data plans. While competitors like Airalo offer capped plans (you pay per GB), Yesim offers unlimited plans in 100+ countries — you pay a flat daily or monthly rate and use as much data as you want. This is transformative for travelers who stream, video call, or post content regularly. No more rationing data or turning off auto-updates.
Pro Tip: Yesim's unlimited plans are genuinely unlimited in most countries — no throttling after a certain amount. However, in a few countries, speeds may be reduced after 50GB in a month. Check the plan details before buying.
Yesim Pricing: Unlimited vs. Capped Plans
Unlimited USA plan: $9.99/week or $24.99/month. Unlimited Europe plan: $12.99/week or $29.99/month. Unlimited Global plan (100+ countries): $19.99/week or $49.99/month. Capped plans are also available for lighter users: 1GB for $3.99, 5GB for $12.99, 10GB for $19.99. For the World Cup: a 5-week unlimited USA plan costs $49.95 — vs. $150–300 in carrier roaming charges.
Yesim's unlimited plans eliminate data anxiety for heavy users
Yesim App: Setup and Features
The Yesim app is clean and well-designed. Setup: download the app, create an account, select your destination and plan, install the eSIM via QR code or automatic installation. The app shows real-time data usage, lets you top up instantly, and has a built-in VPN feature (useful for accessing home streaming services abroad). The app also includes a virtual phone number for calls and texts — a feature Airalo doesn't offer.
Pro Tip: Yesim's virtual phone number feature lets you receive calls and texts on a local number in your destination country. This is useful if you need a local number for hotel bookings, restaurant reservations, or Uber.
Performance: Real-World Speed Tests
We tested Yesim in New York, Miami, Mexico City, London, Paris, Tokyo, Sydney, and Dubai. USA speeds: 35–75 Mbps download, 15–30 Mbps upload — excellent for streaming and video calls. Mexico City: 20–45 Mbps. Europe: 25–55 Mbps. Japan: 40–80 Mbps. Coverage was strong in all major cities. The unlimited plans showed no throttling in our tests — speeds remained consistent throughout.
Who Should Choose Yesim Over Airalo?
Choose Yesim if: you use more than 10GB of data per month, you stream video regularly, you make frequent video calls, you're a content creator posting from events, or you want a virtual local phone number. Choose Airalo if: you're a light-to-moderate data user (under 5GB/month), you want the widest country coverage (200+ vs. 100+), or you want the absolute cheapest option for a short trip.
