    Purchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.

    After 2–3 years of using the service, I encountered a problem for the first time. I can only praise the excellent technical support, which responded very quickly and with whom I exchanged several emails until the final resolution. Professionalism at its best!

    This was my first e-SIM experience, and believe me, the signal is much better than the lines in Turkey. I traveled to four different cities in Indonesia and got 5G in all of them. 5 GB of internet lasted me three weeks. Thank you.

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...
