The mechanics
How Yesim works
- 1
Install the app and buy in-app
Pick your destination and plan inside the app — checkout, eSIM and top-ups all live in one place, no email vouchers.
- 2
One tap installs the eSIM
The app writes the eSIM profile directly — no QR-code juggling, and it can switch host networks automatically where Yesim holds multiple agreements.
- 3
Data starts when you land
The plan activates per its validity window; if you run low, buy a top-up in the app and keep the same eSIM.

FAQ
What do travelers ask about the Yesim eSIM
Which countries does the Yesim eSIM work in?
Yesim sells eSIMs for 50 of the 50 destinations this site tracks, all priced from the same dated snapshot. Its own catalogue lists 200+ destinations in total — we track the 50 where demand is highest. For a specific trip, open that destination's page in the country comparison and every Yesim plan sorts against the field.
How competitive is Yesim on price?
No provider wins everywhere — it depends on the destination. Yesim is the cheapest provider in 42 of the 50 countries where we track its plans (%!d(float64=84)% of its coverage). For example, in United Arab Emirates its plans start at $0.51.
Is there an unlimited Yesim eSIM?
Yes — 1386 of the 1652 plans we track from Yesim are unlimited. Every one carries a fair-use policy that can throttle speed after a threshold, so read the verbatim notes in our fair-use audit before a streaming-heavy trip.
Do I need the Yesim app to use its eSIMs?
Yes — Yesim is app-first: you browse, buy and install plans inside the app (available on the App Store and Google Play), and the eSIM sits alongside your physical SIM rather than replacing it. Buy and install before you fly; on landing, enable data roaming for the eSIM line and it connects by itself.
What is the entry price for Yesim?
The entry price in our database is $0.51 — the smallest bucket in the cheapest destination, not necessarily the right plan for your trip. Sort by $/GB on your destination's page before choosing; prices exclude promo codes and taxes.
Can Yesim be trusted for travel data?
Yesim launched in 2019 and sells app-first plans across 50 destinations. It is operated by GENESIS GROUP AG, headquartered in Zug, Switzerland. It is a sponsored partner of this site — rankings here are still computed by price alone (see our methodology).
Where do I get help with a Yesim eSIM?
Yesim offers 24/7 live chat in the Yesim app, contact form and email. Email: [email protected]. Average response time: 5 minutes (stated on the official contacts page). Before writing in, test once on Wi-Fi and check that data roaming is on for the eSIM line — most "no connection" reports turn out to be a roaming toggle, not a broken eSIM.
Does Yesim give money back if the eSIM fails?
Yesim refunds only completely unused and unactivated services, requested within 30 days of purchase. Technical-issue refunds must be reported within 1 hour of the failure and can take up to 15 business days to review. Amounts of €10 or less may be paid in Ycoins loyalty credit instead of cash. Practical tip: buy a day or two before departure and install at home — if anything fails you still have time to claim. (Summarised from Yesim's published policy; always check their own terms before buying.)
How does Yesim compare with Roamic?
Across the destinations we track, Yesim is the cheapest provider in 42 countries vs Roamic in 6. The full country-by-country table is our Yesim vs Roamic comparison.
