I used this eSIM during my trip to Stockholm, and it worked perfectly throughout my stay. The installation was quick and straightforward, and the connection activated immediately after landing. I had stable coverage across the city

Guest User2026-03-17
To put it mildly, it was fantastic. First of all, the price was low, and I was able to travel around Italy without stress by choosing a plan with 1GB of data per day. Setup was also very easy, and the excellent support that Trip.com offers meant I could buy with peace of mind knowing there was someone I could rely on immediately if any problems arose. I would definitely use it again the next time I go to Europe.
