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. Operator locked devices: If your device is locked to a specific carrier due to a contract, it needs to be unlocked first to be able to use the eSIMs sold on our platform.
Can I use my physical SIM along with the eSIM?
Yes! With dual-SIM functionality you can have both your physical SIM and eSIM active at the same time.

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!

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...

Asian Games 2026 Nagoya: Travel Guide & Venue Tips
