Does my phone support eSIM technology?
The sure way you can verify if your phone is compatible: iPhone: Go Settings -> Cellular (or Mobile Data). If you see ‘Add Cellular Plan’ or ‘Add Mobile Plan’, the phone supports eSIM Samsung: Go Settings -> Connections -> SIM Card Manager. If you see ‘Add Mobile Plan’, the phone supports eSIM Google Pixel: Go Settings -> Networks & Internet -> SIMs -> ‘+Add more’. If you are using Pixel 4/4a or a later model, it will be there. IMPORTANT! Some models have exceptions depending on models and markets.

Yes! With dual-SIM functionality you can have both your physical SIM and eSIM active at the same time.
I already have an active eSIM in my phone, can I use your service?
Yes, your phone can store many eSIM profiles at once. You can choose which one to use at in your phone settings.

"I think this is the fourth time I'm using it abroad. There was only one issue, but the support was very quick. It feels like they are waiting at the screen for fast help. The problem was identified in seconds and a new QR code was sent. Thank you very much."

I needed an eSIM for EU and non-EU counties for the same trip. They had one package at a great price that worked great in all location. The app was great as I was able to check my data balance, in real time, quickly and easily during my trip. Would definitely use MobiMatters again. Downloading the eSIM was quick and easy too. In addition, when I reached out to Customer Support on a minor account issue, they were very responsive and addressed my issue quickly and effectively.

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...
