Description

From the marketplace listing

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.

Comparer forfaits eSIM voyage MyBestSim est un comparateur de forfaits eSIM prépayés pour voyageurs. Il compare les forfaits de plus de 30 fournisseurs eSIM sur 234 destinations, en 25 langues, avec un catalogue mis à jour chaque jour. Dans ChatGPT, MyBestSim propose quatre outils. Rechercher des forfaits eSIM pour une destination, filtrés par volume de données, durée du séjour, données illimitées, budget, disponibilité 5G, ou partage de connexion. Préparer un voyage dans plusieurs pays : l'outil compare un forfait régional unique couvrant tous les pays du trajet à un forfait séparé par pays, et privilégie moins d'eSIM, sauf si découper le trajet en forfaits séparés revient globalement moins cher. Obtenir les prix types d'une destination. Consulter le détail complet d'une offre. Les résultats s'affichent sous forme de carte visuelle dans la conversation. Chaque offre renvoie vers la page comparateur MyBestSim correspondante, dans la langue de l'utilisateur, où la comparaison complète est visible et où l'achat peut continuer chez le fournisseur. MyBestSim ne vend pas d'eSIM directement, l'achat se fait sur le site du fournisseur. Modèle commercial : MyBestSim touche une commission d'affiliation quand un voyageur achète via l'un de ses liens. Les résultats sont les forfaits affichés sur la page comparateur MyBestSim de la destination, celle où mène chaque lien, et aucun placement payé ne modifie leur ordre : ils sont classés uniquement selon leur pertinence par rapport à la demande. Les forfaits affichés sur une page suivent les règles du comparateur : quand deux forfaits sont presque identiques ou comparables, la page peut garder celui d'un fournisseur qui rapporte davantage à MyBestSim, parfois plus cher, et un forfait qu'un fournisseur paie pour mettre en avant n'est jamais retiré par ces règles. Limites : les prix affichés sont indicatifs et peuvent changer sur le site du fournisseur avant l'achat. MyBestSim ne fournit pas de données mobiles lui-même et n'active, ne configure ni ne dépanne aucune eSIM. Il ne couvre pas les forfaits mobiles de résident, seulement les eSIM de voyage prépayées destinées aux visiteurs. Il ne traite aucun paiement, ne demande pas de compte, et ne demande aucune donnée personnelle. Les données techniques de la requête, comme l'adresse IP utilisée pour limiter le débit, sont traitées comme décrit dans la politique de confidentialité. Utile pour les voyageurs qui comparent des options de données pour un seul pays ou un trajet dans plusieurs pays, et pour qui veut connaître rapidement le prix type d'une eSIM pour une destination avant de réserver.
