esimgomobile — Travel eSIM Tools

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.

Use when the user asks for their public IP address. Returns the IP address the request arrives from, as seen by the server edge.

Use when the user wants to know whether they are currently roaming. Compares their home country against the country they are in now.

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.

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

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.

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.

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 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.

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

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 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 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.

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 asks about internet restrictions in a country (VoIP blocks, firewalls). Returns a high-level snapshot from a built-in table — not legal advice.

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

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 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 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 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.

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 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 asks about one specific esimgomobile plan by id - price, data allowance, validity, coverage scope, per-GB unit price, and where to buy.

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 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.

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 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.
