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.
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’ve been travelling around SE Asia for the last 7 months, covering 6 different countries, and this app has been amazing throughout when needing to change eSIM. Very easy set-up when buying one and if you in fact are having some troubles, contacting the support team and talking through email takes no time at all. I was having some difficulty with an eSIM in Vietnam since my phone was not finding a signal no matter what I did - their support team helped me and guided me on different ways to fix it. Thank you!!

It is easy to use and for a 1-2 week vacation it is one of the best choices in terms of price/value, e.g. also for Egyptian eSIM. Now 30 days/5GB 6.5 €, this is cheaper than any other app at the moment

During my 5-day trip to Greece, my wife and I shared the "Europa special 10 GB" package. We used it extensively and without interruption in all 5 days, but only managed to use 5 GB. If I ever travel abroad again, I will definitely choose Mobimatter.

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.

I highly recommend using MobiMatter’s eSIM! I had some problems activating it and couldn’t figure it out on my own, but the MobiMatter team helped me very quickly and explained everything clearly and in detail. Thanks a lot to their support, I was able to activate it and get connected. Great customer service! 😊

I have been using it for about 2 years and I am very satisfied. I used it in Greece, Bulgaria, and Romania, and I experienced internet speeds that I haven't seen in Turkey.

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...
