ネットワーク診断
接続をリアルタイムで測定
Testing uses your current connection and consumes data. Standard mode uses larger samples for more reliable results. Retries and protocol overhead use additional data. Testing starts only when you press Start.
Starting connects to Cloudflare. Cloudflare receives connection information and collects results for aggregated network-quality insights. This shop does not save your test results; you can export them locally.
準備ができたら開始してください
To test your eSIM, turn off Wi-Fi and select it for mobile data. This page cannot identify which SIM is active. Switching tabs stops the test.

Data totals count completed sample payloads only. Retries, aborted transfers, latency probes and protocol overhead are additional; your carrier may bill more. The sample budget is not a hard network-traffic limit.
結果の読み方
Powered by Cloudflare Speedtest. Traffic goes directly from your browser to Cloudflare, not our shop server. Bandwidth uses the SDK’s 90th percentile of eligible samples, not an average including ramp-up waits. Routing, device, VPN and competing traffic affect results. Different providers can report different speeds. A run stops after two minutes.
Compare with Cloudflare’s official test (opens a new tab)Latency is HTTPS response timing, not ICMP ping. We use 20 idle probes and show the median, p95 and mean consecutive difference (jitter). Loaded latency comes from SDK probes during transfers. Missing samples show a dash. Packet loss is not measured.
