Real-World: Saily on a 5-Day Tokyo Business + Leisure Trip

Saily targets a specific niche: people who want things simple, fast, and private. Here's a real scenario.

Day before (Berlin):

Downloaded the Saily app, picked the 5GB / 30-day plan for $13. Cheapest option at this tier. Setup was dead simple — two taps and the eSIM installed. As a NordVPN subscriber, the app felt familiar. No promo codes needed, the price was already good.

Haneda Airport, 10 PM:

Late arrival. No time for WiFi counters or SIM shops — most are closed anyway. Turned on the eSIM in Settings. Connected to KDDI au within 30 seconds. Ordered a taxi through the GO app while walking to the arrivals exit.

Shibuya (remote work), Days 1–3:

Working from a hotel and coworking space. Speed test: 295 Mbps down, 45 Mbps up on KDDI au 5G in central Shibuya. Multiple Zoom calls, screen sharing, Slack all day. Used about 1.5 GB per work day — heavier than tourist usage.

Kamakura day trip, Day 4:

Solid 4G coverage across the Enoden line, at the Great Buddha, and along the coastal walk. Slight dip in speed at Hasedera temple (valley geography), but Google Maps and camera translation never failed.

Shinjuku nightlife, Day 5:

Late-night ramen crawl in Golden Gai — tiny alleyways with cramped bars. Signal held up even in basement-level bars. Used Google Translate camera mode to read the handwritten menu at a place with no English. Ordered the chef's recommendation. No regrets.

Total data used: 4.1 GB over 5 days (heavy use with remote work). Would need 10GB for a full work week.

Verdict: Saily is the "quiet confidence" pick. No frills, no upsells, just fast data from a privacy-respecting company. Great for business travelers and digital nomads who don't want to think about it.
