🟢build_travel_connectivity_guide(stops, travelers, usageProfile, hotspot, deviceReadiness, ...)

Creates a free, provider-neutral mobile-data estimate and readiness checklist for a travel route. Use it for trip data budgeting, hotspot planning, offline readiness, and connection fallback advice. Do not use it for a pure phone eSIM compatibility question; use check_esim_device_compatibility instead. It does not browse, compare, promote, recommend, price, sell, or link to products, plans, carriers, or connectivity services.

🟢check_esim_device_compatibility(manufacturer, model, region, carrierUnlocked, eidPresent, ...)

Use this tool whenever the user asks whether a phone supports eSIM or is ready for a travel eSIM. Check an exact phone model against Skyalo's manufacturer-sourced compatibility catalog, including regional variants, carrier locks, EID, and Add eSIM settings. Do not call build_travel_connectivity_guide for a pure device question. Unknown never means incompatible. This tool does not search, compare, recommend, price, sell, or link to connectivity plans.
