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.

Since I started using MobiMatter, I have never once encountered a problem that they haven’t responded to almost immediately. I guess this is what sets them apart. Excellent customer service, very detailed troubleshooting instructions, and a support team that genuinely follows through until the issue is resolved. The app is easy to use, the eSIM installation process is straightforward, and the profes are competitive. Highly recommended for anyone who wants reliable connectivity while travelling.

A very fast, reliable, and fantastic internet provider. I got internet that I can use for one month in 3 countries (Thailand, Singapore, Malaysia) for a total of 696 TL (14.99$).

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.
