esimgomobile — Travel eSIM Tools

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).

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.

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.

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.

Use when the user asks whether a country is covered by esimgomobile plans. Answers from esimgomobile's published coverage list and plan catalog (pricing shown as catalog pricing only) plus the built-in country network reference.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Use when the user needs step-by-step eSIM installation instructions. Covers iPhone and Android, via QR code or manual entry.

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.

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.

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.

Use when the user is about to use public, hotel, or airport Wi-Fi. Returns a practical safety checklist.

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.

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).

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.

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

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.

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.

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.

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.

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.

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.

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.

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).

Use when the user wants to stretch a travel data plan. Gives OS-specific steps: low-data mode, background limits, offline maps and downloads.

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.

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.

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 nothing.
