While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Used SonaSIM eSIM on a recent tripSonaSIM in Japan – Seamless Travel Connectivity from Landing to Departure to…

Used SonaSIM eSIM on a recent trip to Japan and it made things way easier than I expected. Landing in Tokyo, I was connected within minutes — no queues, no hunting for SIM cards, just scanned the QR code and it worked.

Coverage was solid pretty much everywhere I went — Tokyo, Kyoto, even on trains between cities. Speeds were fast enough for Google Maps, translations, booking trains, and streaming without any issues.

One thing I really liked was not having to think about it. No random dropouts, no surprise charges, it just worked in the background the whole trip.

If you’re heading to Japan and don’t want the hassle of physical SIMs or crazy roaming fees, SonaSIM is a really easy option.
