Yesim sells two kinds of plan on most islands: fixed data that lasts 30 days, and unlimited day passes for 1 to 30 days. The 30-day plans suit a long stay; the day passes suit a short port call when you want to stream or share a hotspot.

Yesim has no plan for Bonaire.
What to know before you buy
- You choose when the plan starts. Yesim’s Bermuda page says plans can start instantly or be delayed for up to 365 days.
- Unlimited isn’t always full speed. Yesim’s page says speed may be reduced after a daily amount, depending on the network.
- Hotspot depends on the operator, according to Yesim’s own plan details.
- Data only. There’s no phone number; WhatsApp and other apps keep working on your usual number.
- Top-ups are possible while the plan is active.
What’s good
- Unlimited day passes on most islands, for heavy use on a short stop.
- Fixed plans last 30 days, so a slow week doesn’t waste data.
- You can buy months ahead and start the plan later.
What’s not
- No Bonaire plan.
- Per GB, the fixed plans usually cost more than Saily’s or Roamless’s on the same island.
- Refunds of €10 or less come back as Yesim credit, not money.
Refunds and support
Yesim’s refund policy allows a refund within 30 days of purchase, but only if the eSIM hasn’t been activated, used or expired. Installing the eSIM counts as activation. Approved refunds of €10 or less go to your Yesim balance as Ycoins; larger ones go back to your card within 15 business days. If the app or plan fails, report it to [email protected] or the in-app form within one hour, with screenshots.
Alternatives to Yesim
- Holafly: unlimited plans on most islands.

Common questions
Is Yesim unlimited really unlimited?
Data doesn’t run out, but Yesim says speed may be reduced after a daily amount, depending on the local network.
Does Yesim work in Bonaire?
Not with a plan we could find. For Bonaire, look at Saily, Airalo, GigSky or Roamless.
Can I get a refund on Yesim?
Within 30 days, if you haven’t installed or used the eSIM. Small refunds (€10 or less) come back as Yesim credit.
