Description

eSIM For U helps travellers get mobile data abroad without a local SIM card. Ask about a destination and the plugin shows the data plans that are currently available there, with data amount, validity and the price shown on esimforu.app. It can estimate how much data a trip needs from the number of days and how the phone is used, check whether a phone model supports eSIM, and walk through installing and turning on an eSIM on iPhone and Android. Plans are data-only: no phone number, no calls and no SMS. Prices and availability come live from esimforu.app and can change. Each answer links to the destination page on esimforu.app for full details.

Tools

5 tools agents can invoke

Use this when the user asks whether their phone supports eSIM (e.g. "Does my iPhone 12 support eSIM?"). Looks up the model in the eSIM For U list of eSIM-capable iPhone, Samsung Galaxy and Google Pixel models and returns the result with model-specific notes and the reliable self-check (*#06# shows an EID). Limitations: the list covers the most common models only; support can depend on the country the phone was sold in and on carrier lock, so a listed model is a strong hint, not a guarantee.
check_device_esim_support
Use this when the user is unsure how much mobile data they need for a trip. Deterministic estimate: days × typical daily use for the chosen usage level (light 0.3 GB/day: maps, messaging, email; typical 0.7 GB/day: plus ride/booking apps and some social media; heavy 1.5 GB/day: lots of video, video calls or hotspot) plus a 10% buffer, rounded up to a common plan size. Pass the result as gb to get_destination_plans. Limitations: a rough guide only; actual use varies with apps, video quality and Wi-Fi availability.
estimate_data_needed
Use this when the user asks how to install or set up a travel eSIM, what to switch on after landing, or why the eSIM has no internet. Returns the eSIM For U step-by-step guide for iPhone or Android (Samsung Galaxy, Google Pixel and similar), optionally limited to one topic, with a link to the full guide. Limitations: general guidance only; it cannot see or change the user's phone or eSIM.
get_install_help
Use this when the user names a country, city, island or region they are travelling to and you need the matching eSIM For U destination. Returns matching countries and multi-country regions (e.g. Europe, Southeast Asia, Global) with the lowest current plan price and a link to the destination page on esimforu.app. Pass the returned code to get_destination_plans to see the plans. Limitations: only destinations in the eSIM For U catalog; names are matched in English; it does not buy anything.
search_destinations
Use this when the user wants to know which eSIM For U data plans exist for a destination and what they cost. Takes a destination code from search_destinations (or an English country name) and optionally the trip length in days and the data needed in GB; returns matching plans (data amount, validity, current price) plus daily passes when days are given, and shows them as an information card with a link to the destination page on esimforu.app. Limitations: plans are data only (no phone number or SMS); prices are shown in the user's local currency where supported, otherwise USD; this tool does not buy or reserve anything.
