    During my 5-day trip to Greece, my wife and I shared the "Europa special 10 GB" package. We used it extensively and without interruption in all 5 days, but only managed to use 5 GB. If I ever travel abroad again, I will definitely choose Mobimatter.

    I've tried many different platforms until now, but I've been using Matter for the last 3 months. The price, performance, signal strength, fast border crossings – in a single sentence, it's a perfect platform 🙏🙏🙏

    I bought the service for the second time for a trip to Turkey. I had some trouble finding the right settings on my iphone. Support helped out immediately and everything was working well when I arrived in Turkey.

    I didn't experience any problems in Europe; it works quite well, and it's also more affordable compared to other apps.

    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 bought 6GB for my Paris and Benelux tour. It was more than enough. It worked perfectly everywhere. To activate it, you need to enable the mobile data option.

    I bought two esims for two different countries because mobimatter has affordable prices. I had an issue connecting the second esim. The helpdesk responded fast. It turns out I was using the first eSIM instead of the second. Thanks for good data in both countries and for responding fast!

    It's the most easiest simplest way of taking data with you. A quick flick of the sim button and that's it. Highly recommended.

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...

South Korea Travel & Data Guide 2026: Autumn Foliage, K-Culture & eSIMs

Autumn in Korea: Best Viewing Spots and Weather Prep South Korea's 2026 foliage season runs roughly late September to mid-November, starting on the high northern slopes of Seoraksan and rolling south and downhill toward Seoul, Gyeongju, and Naejangsan over about six weeks. Korea's official 2026 foliage forecast from the Korea Forest Service is typically released in September, but the pattern repeats closely enough year to year to plan around. Color moves along two axes at once: north to south,...

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...
