    I have used this app multiple times and have been really happy with the service. When I've had an issue I've been able to troubleshoot it with the online instructions and if that doesn't work it is quickly resolved.

    I used it for the first time with my wife during our trip to Japan and Korea, and I didn't experience any connection problems. The internet was fast enough in both Japan and Korea, and I was satisfied with the app. I recommend it.

    I've tried a few eSIM apps and MobiMatters is the best. They have real customer support, lots of packages, and the service has worked very well in Australia, Singapore, Montenegro and other places. I highly recommend them.

    MobiMatters came highly recommended in family-oriented travel groups on social networks, when I was researching on travel eSIMs for Iceland. The first package I started with was a US + Europe - it was easy to activate before leaving home (and verifying), and then continue on landing in Reykjavik. Unthinkable speeds (given we are used to Verizon and TMobile in the US) - over 400 Mbps on the Fast app! Unlimited tethering options allowed me to use across my MacBook and phone, as well as share across the family with the kids on iPads and phones. Navigation on Google and Waze was aa breeze with the constant high speed data connectivity. Our plans did not support phones (we knew this) but with WhatsApp and FaceTime allowing audio and video calls we never felt the need for basic phone service. Customer service on email was responsive and helpful when I wanted to understand how top-ups work. Highly recommend MobiMatters - I’m on my third top-up as we speak!

    An excellent app with very reasonable prices compared to the exorbitant prices in Türkiye. The internet speed is excellent, and it provides 5G coverage, provided the phone supports eSIM functionality.

China Golden Week 2026: 15 Outbound Hotspots for October's Massive Travel Rush

What is Golden Week 2026 and Why the Travel Surge is so Big Golden Week 2026 runs from October 1 through October 7, a seven-day national holiday built around China's National Day. Because 2026's Mid-Autumn Festival falls a full week earlier, on September 25 to 27, the two holidays stay separate this year rather than merging into one extended break, so the October holiday keeps its standard seven-day shape. That seven-day window is still enough to trigger one of the largest travel movements on t...

The 20 Best Places to See Autumn Foliage in October 2026

Why October 2026 is the Best Month to Chase Autumn Colour October is the only month in which the northern hemisphere's three great foliage regions overlap. Japan's mountain interior, the Alpine and Carpathian belt across central Europe, and the North American maple corridor all carry colour somewhere within the same thirty-one days. No other month gives a traveller that choice, and the practical consequence is that a single trip can be planned around colour rather than around a holiday calendar...

Asian Games 2026 Nagoya: Travel Guide & Venue Tips

The 20th Asian Games (Aichi-Nagoya 2026) runs September 19 to October 4, 2026, with select events starting as early as September 10, across roughly 53 venues in Aichi Prefecture and Nagoya, Japan. Expect 43 sports, 469 gold medals, and athletes from 46 nations. The fastest way in is the Tokaido Shinkansen: about 94 minutes from Tokyo and 47 minutes from Shin-Osaka on the Nozomi service. Between sessions, Nagoya Castle, the Sakae shopping district, and the city's food scene fill the gaps easily....
