almost perfect
The one day that i needed the mobile data most due to work, that day for 2 hours the network was not working at all for technical reasons. The rest of the days were good though. This is reason i do not give 5 stars

Would 100% recommend
It was easy to buy and install the eSIM. It worked as soon as we landed in Italy. It worked the entire time without fault. We had ample data. Would 100% recommend.

First time using e-sim:iphone 17
First time using e-sim. Generally seamless into iPhone 17. I was not aware you can't text locally or make phone calls unless you use VOIP or WhatsApp which is a shame..

The SIM card was easy to purchase and the speeds in Osaka, Japan are very high. Coverage has been excellent as well. You can’t go wrong with Ubigi.
