The 39 tools it listed

"Read only" and "Changes data" are the server's own marks. Underlined parameters are required.

  1. calculate_data_budgetRead only

    Data Budget Calculator

    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).

    plan_gb used_gb days_total days_elapsed

  2. calculate_roaming_costRead only

    Roaming Cost Calculator

    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.

    days home_carrier_daily_rate_usd

  3. check_activation_details_formatRead only

    Activation Details Format Check

    Matches the free website details check. Checks email and order-reference formats only. Does not verify ownership, retrieve activation codes, generate QR codes or send email. Contact support for a reissue.

    email order_reference

  4. check_carrier_lockRead only

    Carrier-Lock Check

    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.

  5. check_coverageRead only

    Coverage Checker

  6. check_device_compatibilityRead only

    Device Compatibility

    Use when the user asks whether their phone supports eSIM. Checks the model against a built-in device table, with a manual fallback check.

    device_model

  7. check_dns_leaksRead only

    DNS Leak Test

    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.

  8. check_internet_freedomRead only

    Internet Freedom Check

    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.

    country

  9. check_roaming_statusRead only

    Am I Roaming?

    Compares entered countries using country names and ISO codes, with conditional official roaming guidance. Does not detect the registered network, verify plan eligibility, establish eSIM coverage or guarantee charges.

    home_country current_country

  10. compare_plansRead only

    Compare Plans

    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.

    plan_ids

  11. detect_captive_portalRead only

    Captive Portal / Public Wi-Fi Detector

    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.

  12. estimate_data_usageRead only

    Data Usage Estimator

    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.

    days hours_per_day usage_profile

  13. find_best_networkRead only

    Best Network by City

    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.

    city country

  14. find_free_wifiRead only

    Free Wi-Fi Finder

    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.

    city

  15. forecast_data_thresholdRead only

    Low-Data Forecast

    Matches the free website forecast: estimates when a usage threshold is reached from plan size, usage profile and days elapsed. Does not set alerts, monitor an account, or read carrier usage.

    plan_gb threshold_percent usage_profile days_elapsed

  16. format_international_numberRead only

    Dialing Helper

    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.

    from_country to_country phone_number

  17. get_airport_connectivityRead only

    Airport Connectivity

    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.

    os method

  20. get_plan_detailsRead only

    Plan Details

    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.

    plan_id

  21. get_public_ipRead only

    What's My IP

    Returns the IP address of the caller or connector reaching this server. An AI client may call from its own server, so this is not proof of the user device public IP. For a device-side lookup open the website tool.

  22. get_travel_data_checklistRead only

    Travel Data Checklist

    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.

    country

  27. list_sample_esimsRead only

    Sample eSIM Library

    Matches the free website sample preview. Returns explicitly fictional example profiles, never your real eSIMs or account balances. No account connection.

  28. lookup_apn_settingsRead only

    APN Lookup

    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.

    carrier

  29. lookup_speed_requirementsRead only

    Speed Needed For

    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.

    activity

  30. measure_latencyRead only

    Latency to Destination

    Measures an HTTPS HEAD request from the server edge to a public host, not from the user device. The free website tool instead measures browser-to-esimgomobile timing. These paths and results are different.

  33. recommend_planRead only

    Plan Recommender

    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.

    countries days usage_profile

  34. run_speed_testRead only

    Speed Test

    Opens a website speed-test handoff. No speed is measured in this chat or by this MCP call. Open https://esimgomobile.com/tools/run-speed-test/ on the device you want to check.

  35. search_plansRead only

    Search Plans

    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).

    kind max_price_usd min_gb scope sort
