👍 What we like

✓Pay & Fly pay-as-you-go mode: load a Ycoins wallet and pay only for the data you actually use instead of a fixed package

✓Purchases can sit dormant — choose "Activate later" and start the plan any time within 12 months

✓Extras built into the app: a built-in VPN and rentable virtual phone numbers (USA, UK, Canada, Netherlands)

✓Large unlimited selection — 1284 of the 2292 Yesim plans we track are unlimited

✓Hotspot/tethering is enabled by default at no extra charge

✓Broad payment support: Visa, Mastercard, PayPal, Apple Pay and Google Pay

👎 Worth noting

–All plans are data-only — no voice calls or native SMS, so you rely on messaging apps

–Refunds of 10 EUR or less are paid out as Ycoins app credit, not back to your card, and Ycoins are non-refundable

–The best features (Pay & Fly, wallet top-ups, VPN, virtual numbers) require using the Yesim app rather than a simple QR-only flow

–Refund requests can take up to 15 business days to review, and used or expired data is never refunded

Yesim — quick answers

What is the cheapest Yesim plan available right now?

Across the 2292 live Yesim plans we track in 185 countries, prices currently start at $0.53. Because Yesim sells both small country packages and large unlimited bundles, it is worth comparing the per-GB price on our country pages rather than just the headline price.

Does Yesim sell unlimited data plans?

Yes — 1284 of the 2292 Yesim plans in our catalog are unlimited data plans, spanning single countries and multi-country packages. Note that on Unlim Day Pass plans a day counts as used as soon as your device connects to a mobile network, which also affects refund eligibility for that day.

Can I buy a Yesim eSIM now and activate it later?

Yes. During checkout you can tap "Activate later" and start the plan any time within the next 12 months, which is unusually long for travel eSIMs. Installation is one-click inside the Yesim app, or via a QR code emailed to you if you buy on the website.

How does Yesim's Pay & Fly pay-as-you-go option work?

Pay & Fly is a wallet-based mode bought through the Yesim app: you top up with Ycoins (1 Ycoin = 1 EUR), install the Pay & Fly eSIM, and Yesim deducts from your balance based on the exact data you use across 200+ destinations. It suits light users and multi-country trips where a fixed package would go partly unused, though it is managed in the app rather than sold as a normal package.

What extras does the Yesim app include besides mobile data?

The app bundles a built-in VPN and lets you rent virtual phone numbers (options include the USA, UK, Canada and Netherlands) for messenger calls and SMS verification. Hotspot sharing is also enabled by default on data plans at no extra cost.
