Just got back from my Japan trip and this SIM was a total game-changer! The 25GB lasted me the full 20 days with some hotspot sharing to my tablet. Speeds were consistently fast in Tokyo, Kyoto, and even rural areas around Mount Fuji.

The plug-and-play aspect worked exactly as advertised - popped it in at Narita Airport and had instant 5G. Pro tip: bring a paperclip for the SIM tray! The 3-in-1 design fit perfectly in my iPhone 13.

Had one minor panic when it didn't immediately connect, but remembered the note about enabling roaming. After toggling that setting, everything worked flawlessly. Used Google Maps constantly and streamed some YouTube without buffering.

The only downside? No phone number means you'll need WhatsApp/Viber for calls. But honestly who makes actual calls while traveling these days? For $25 this was way better than my carrier's $10/day roaming plan!

Would absolutely buy again for my next Asia trip. Just make sure your phone is unlocked before departure!
