It's a great app. I haven't had any problems with the internet.

I used it in Italy in 2024 and in Spain in 2026, and I was very satisfied. The app has improved day by day, and I never experienced any issues. I don't know about other apps, but I highly recommend MobiMatter. I bought 15GB of internet in Spain, and even though I didn't use that much, I still have 10GB left.

Amazing service! I’ve used Mobimatter many times and I’m always impressed by how fast and helpful their support team is. They assisted me quickly whenever I had a question, and everything was resolved smoothly. The eSIMs are reliable, easy to install, and work exactly as expected. I keep coming back because the service is consistently excellent.

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...
