Speed Test
Measure your real download and latency first.
Open toolPaste in your download, upload and ping numbers — get an Excellent / Good / Fair / Poor grade with plain-English advice on what the connection can handle.
“47 Mbps down, 90 ms ping” — so what? Can you take the Zoom call? Stream the match? This grader applies fixed, transparent thresholds to your numbers and tells you exactly what the connection is good for.
Excellent needs 50+ Mbps down and ≤30 ms ping; Good 25+ Mbps and ≤60 ms; Fair 10+ Mbps and ≤120 ms. No black box — the rules are on this page.
A 100 Mbps line with 300 ms ping is miserable for calls and gaming. The grader weighs latency alongside bandwidth, like reality does.
Each verdict ships with what to do: what works, what to avoid, and when to switch to your eSIM’s mobile data instead.
No numbers handy? Run our speed test first, then grade the result here.
Enter the three numbers from any speed test. The grade uses the exact thresholds from our published tool — nothing hidden.
In the esimgomobile ChatGPT app and API, this tool is called with exactly these parameters — nothing hidden, nothing invented.
| Parameter | Type | What it is |
|---|---|---|
download_mbps | number | Download speed in megabits per second. |
upload_mbps | number | Upload speed in megabits per second. |
ping_ms | number | Round-trip latency in milliseconds. |
The grader judges the numbers you give it — it can’t measure your connection itself (that’s the speed test’s job) and it can’t fix a bad one. Grades are guidance, not guarantees: a “Good” hotel Wi-Fi at 3am may be “Poor” at 8pm when everyone’s streaming. Re-grade when conditions change.

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 Connection Quality Grader once while planning and once on the road. Both visits take under a minute.

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.

And if you'd rather talk it through, the Tele Agent answers the same questions conversationally, any time.
Every tool result points somewhere useful: usually a plan that fits, sometimes a guide that goes deeper.
From here the path is short — pick a plan, check out through Amazon Pay, scan the QR code, and you're done.
