Daily 1GB High-Speed, then Unlimited at Reduced Speed

You can choose your eSIM duration and data allowance. We opted for a 5-day plan with 1GB of high-speed data per day, followed by unlimited data at a reduced speed. This was more than enough for us, especially since our accommodation had Wi-Fi.

Effortless eSIM Installation

Another reason to recommend USIMSA? Their installation process is incredibly straightforward, thanks to their clear and comprehensive guides. Once you purchase, you'll receive a notification with step-by-step instructions. We even set ours up on the train ride to the airport!

The guide clearly outlines what to turn on and off, making it super easy! I remember the days of picking up bulky Wi-Fi devices, carrying them around, charging them, and then having to return them. Now, almost everyone seems to be using eSIMs – and for good reason!

Setting up the eSIM with the guide in hand was a breeze! If you ever run into trouble, USIMSA's customer service is there to help.
