Tools

• calculate_data_budget ~246 tokens
  Use when the user asks how much of their plan data is left or how to ration it over a trip. Computes remaining data, daily budget and end-of-trip projection from the plan size and usage so far (which the user's phone reports exactly).
• calculate_roaming_cost ~176 tokens
  Use when the user wants to compare their home carrier's roaming fees against a travel eSIM. Compares a user-supplied carrier day-pass rate with an illustrative travel-eSIM daily rate.
• check_carrier_lock ~85 tokens
  Use when the user needs to check whether their phone is carrier-unlocked (required for travel eSIMs). Walks through the check on iPhone and Android.
• check_coverage ~131 tokens
  Use when the user asks whether a country is covered by esimgomobile plans. Answers from esimgomobile's own published plan catalog (live-checked) plus the built-in country network reference.
• check_device_compatibility ~127 tokens
  Use when the user asks whether their phone supports eSIM. Checks the model against a built-in device table, with a manual fallback check.
• check_dns_leaks ~86 tokens
  Use when the user wants to check whether their DNS queries leak outside their VPN. Gives a guided manual check — browsers cannot run automatic DNS probes.
• check_internet_freedom ~122 tokens
  Use when the user asks about internet restrictions in a country (VoIP blocks, firewalls). Returns a high-level snapshot from a built-in table — not legal advice.
• check_roaming_status ~152 tokens
  Use when the user wants to know whether they are currently roaming. Compares their home country against the country they are in now.
• compare_plans ~151 tokens
  Use when the user is choosing between 2-4 esimgomobile plans. Side-by-side price, data, validity, scope and per-GB unit price, with a best-value pick. No competitor API offers this.
• detect_captive_portal ~86 tokens
  Use when the user is on hotel/airport/cafe Wi-Fi and suspects a login page is blocking them. Gives a step-by-step guided check — no automatic probing.
• estimate_data_usage ~199 tokens
  Use when the user is planning a trip and asks how much mobile data they need. Estimates from trip days, daily hours online, and a light/moderate/heavy usage profile, then suggests a plan size.
• find_best_network ~150 tokens
  Use when the user asks which mobile network is best in a specific city. Ranks operators by observed cell-tower density from the OpenCelliD open dataset — a coverage proxy, not a speed measurement.
• find_free_wifi ~126 tokens
  Use when the user asks where to find free Wi-Fi in a city. Queries the live OpenStreetMap directory (Nominatim geocoding + Overpass) for community-mapped free Wi-Fi hotspots near the city.
• format_international_number ~188 tokens
  Use when the user needs to dial a local number internationally. Formats a local phone number for calling between two countries, using a built-in dialing-code table.
• get_airport_connectivity ~146 tokens
  Use when the user asks about connectivity at an airport (Wi-Fi, SIM vendors, eSIM tips). Answers from a researched dataset of major international airports: free Wi-Fi details, where to buy a SIM, and eSIM options on arrival.
• get_country_fact_sheet ~127 tokens
  Use when the user asks about mobile networks, eSIM support, or Wi-Fi in a country. Returns a fact sheet from a built-in table, with general guidance where a country isn't listed.
• get_installation_guide ~139 tokens
  Use when the user needs step-by-step eSIM installation instructions. Covers iPhone and Android, via QR code or manual entry.
• get_plan_details ~133 tokens
  Use when the user asks about one specific esimgomobile plan by id - price, data allowance, validity, coverage scope, per-GB unit price, and where to buy.
• get_public_ip ~78 tokens
  Use when the user asks for their public IP address. Returns the IP address the request arrives from, as seen by the server edge.
• get_travel_data_checklist ~202 tokens
  Use when the user is preparing a trip and wants one pass over everything data-related for a country: networks, eSIM support, internet freedom, device check and install steps. Composes the built-in country, freedom, device and install references.
• get_wifi_security_checklist ~75 tokens
  Use when the user is about to use public, hotel, or airport Wi-Fi. Returns a practical safety checklist.
• grade_connection_quality ~171 tokens
  Use when the user gives you download/upload speed and ping numbers and wants a verdict. Grades the connection Excellent/Good/Fair/Poor with practical advice.
• list_available_plans ~95 tokens
  Use when the user asks what esimgomobile plans exist or what an eSIM costs. Lists the real, currently published plan catalog with USD prices (live-checked against esimgomobile.com).
• list_country_networks ~143 tokens
  Use when the user asks which mobile networks operate in a country, or for eSIM support / Wi-Fi / internet-freedom facts for one country - the eSIM Go /networks parity endpoint, from esimgomobile's built-in reference.
• lookup_apn_settings ~127 tokens
  Use when the user needs APN settings for a carrier after installing an eSIM. Looks up a built-in APN table; most travel eSIMs configure automatically.
• lookup_speed_requirements ~131 tokens
  Use when the user asks how much bandwidth an activity needs (video calls, 4K streaming, gaming). Looks up reference requirements from a built-in table.
• measure_latency ~138 tokens
  Use when the user wants the network latency to a host. Performs a real HTTPS HEAD request from the deployment edge and reports round-trip time to first byte in milliseconds.
• plan_multi_country_esim ~140 tokens
  Use when the user has a multi-country itinerary and asks which eSIM plan type fits. Recommends single-country vs regional vs global plans from the country list.
• plan_trip ~240 tokens
  Use when the user gives an itinerary (countries + days + usage) and wants the full answer in one call: estimated data need, best published plan pick with an alternative, and a per-country networks/eSIM/freedom brief. Composite over the live catalog and built-in country references.
• recommend_plan ~218 tokens
  Use when the user says where they're going, for how long, and roughly how much they'll use data, and wants a concrete plan pick. Estimates the GB need, then picks the cheapest matching plan from the real published catalog with prices.
• run_speed_test ~91 tokens
  Use when the user wants to measure their current internet speed. Runs a real download/ping measurement in the interactive widget and reports Mbps, ping, and a quality grade.
• search_plans ~284 tokens
  Use when the user wants to browse or filter esimgomobile plans - by type (data packs, monthly, day passes), max price, minimum GB, coverage scope, or cheapest per-GB. Reads the live published catalog (snapshot fallback, labeled).
• setup_data_saver ~116 tokens
  Use when the user wants to stretch a travel data plan. Gives OS-specific steps: low-data mode, background limits, offline maps and downloads.
• setup_dual_sim ~131 tokens
  Use when the user runs a home line plus a travel eSIM and needs the right configuration. Explains which line handles data, calls, and iMessage, and how to avoid roaming charges.
• troubleshoot_esim ~145 tokens
  Use when the user's eSIM isn't working. Diagnoses common problems: no service, no data, slow data, QR issues, activation failures, calls not working.
• validate_order_draft ~260 tokens
  Use when the user is about to buy and wants everything checked first - the eSIM Go validate-style dry run. Verifies the plan id exists, quantity (1-50), device eSIM compatibility, and single-country scope against the itinerary, then gives a published-price estimate. Places no order and charges nothi
