Frequently Asked Questions
Does an Italy eSIM work in Sardinia?
Yes. Sardinia is part of Italy, so Italy plans work there on Italian networks such as TIM, Vodafone and WindTre, as do Europe plans that list Italy. On the ferry from the mainland your phone may connect to a ship's satellite network, which EU roaming rules don't cover: switch data roaming off or use airplane mode on board.

Mentions SardiniaI used it in Italy in 2024 and in Spain in 2026, and I was very satisfied. The app has improved day by day, and I never experienced any issues. I don't know about other apps, but I highly recommend MobiMatter. I bought 15GB of internet in Spain, and even though I didn't use that much, I still have 10GB left.

One of the best and most valuable service providers at a reasonable price. Highly recommended! As a seafarer, this service is extremely useful. I have never seen any other eSIM or physical SIM service provider offering such a wide variety of packages. Thank you for your excellent service!

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 recently used their service and I’m extremely satisfied. The package lasted longer than expected, and I was able to make great use of it across the Asian region. They also have the fastest support team — very responsive and incredibly detailed in the information they provide.
