MyBestSim

MyBestSim is a comparator for prepaid travel eSIM plans. It compares plans from more than 30 eSIM providers across 234 destinations, in 25 languages, with the catalog refreshed daily.

Inside ChatGPT, MyBestSim offers four tools. Search eSIM plans for a destination, filtered by data allowance, trip length, unlimited data, budget, 5G availability, or hotspot and tethering support. Plan a multi-country trip: it compares one regional plan that covers every country on the itinerary against a separate plan for each country, and favors fewer eSIMs unless splitting the trip into separate country plans works out cheaper overall. Get an overview of typical eSIM prices for a destination. Look up the full detail of a specific plan.

Results appear as a visual card in the conversation. Each plan links to the matching MyBestSim comparator page for that destination, in the user's language, where the full comparison is visible and the purchase can continue on the provider's own site. MyBestSim does not sell eSIMs directly; the purchase happens on the provider's website.

Commercial model: MyBestSim earns an affiliate commission when a traveler buys through one of its links. Results are the plans listed on MyBestSim's comparator page for the destination, which is where each link leads, and no paid placement changes their order: they are ranked by fit to the request only. Which plans a page lists follows the comparator's rules: when two plans are nearly identical or comparable, the page may keep the one from a provider that earns MyBestSim more, sometimes at a higher price, and a plan a provider pays to feature is never removed by these rules.

Limitations: prices shown are indicative and can change on the provider's site before checkout. MyBestSim does not provide mobile data itself and does not activate, configure or support any eSIM. It does not cover domestic or resident mobile plans, only prepaid travel eSIMs aimed at visitors. It does not process payments, does not require an account, and does not ask for personal data. Technical request data, such as the IP address used for rate limiting, is handled as described in the privacy policy.

Useful for travelers comparing data options for a single country or a multi-country itinerary, and for anyone who wants a quick read on typical eSIM pricing for a destination before booking.
