I used MobiMatter with a Sparks plan for Albania and Montenegro, and everything worked perfectly for me. I had excellent reception almost the entire time, and mostly even 5G. I can definitely recommend this offer for these two countries!

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.

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.
