Speed Test
Measure what your connection can actually do.
Open toolThe address the internet sees when you browse. One tap reveals it — shown only to you, stored nowhere.
Every device on the internet has a public IP address — the return address on everything you send. Knowing it is the first step in VPN checks, remote-access setup, and “why is this blocked?” debugging.
One tap and the address is on screen. No account, no email, no tracking — the lookup is a single echo request.
Your IP is displayed only in your browser. esimgomobile doesn’t log it, store it, or tie it to you.
Connect your VPN and check again — if the address doesn’t change, your VPN isn’t routing traffic. Simple as that.
Switch from Wi-Fi to mobile data (or your travel eSIM) and you’ll get a different address — that’s normal and expected.
Tap once. Your browser asks a public echo service for the address it sees — that’s your public IP.
—
Shown only to you. This page doesn’t store it, and neither do we. Location is approximate — usually the right city, sometimes not even that.
Uses the public ipify echo service (api.ipify.org) for the address and the keyless ipapi.co lookup for ISP/location details. If a service is unreachable, the button will say so — we don’t invent data.
In the esimgomobile ChatGPT app and API, this tool is called with exactly these parameters — nothing hidden, nothing invented.
This tool takes no parameters — it works with one tap.
This tool shows your IP plus your ISP, approximate location and network (ASN) — resolved live by public lookup services and shown only to you. It can’t name who owns the connection beyond the ISP, or tell you whether it’s “safe.” IP geolocation is approximate at best (often just the right city, sometimes not even that). And remember: this is the address of your current network, not your device — everyone on the same Wi-Fi shares it.

Explainer
The pattern is always the same: tell the tool a little about your trip, and it does the research you'd otherwise do across ten tabs.
Tools are free and instant. They're the fastest way to turn a vague travel question into a concrete next step.
Explainer
Bookmark it — travel questions have a habit of returning at the worst moment.
Most travelers use What’s My IP? once while planning and once on the road. Both visits take under a minute.
Explainer
The tool is only as good as its inputs — a rough date range beats a perfect one you never enter.
If a result surprises you, rerun with different inputs. Exploring the options is the point.
Explainer
Every tool result points somewhere useful: usually a plan that fits, sometimes a guide that goes deeper.
And if you'd rather talk it through, the Tele Agent answers the same questions conversationally, any time.
From here the path is short — pick a plan, check out through Amazon Pay, scan the QR code, and you're done.
