Got data instantly and it was 5G out at sea on a cruise ship and it also works in Gibraltar so nothing but good things to say

★

Guest User2026-04-15

Excellent eSIM. Coverage was alright throughout Copenhagen and Norway. It’s 5G throughout and it’s even faster than hotel’s wifi. Excellent buy! And will re-purchase again.

Guest User2026-04-04

Excellent eSIM! I used it while traveling through Serbia and Montenegro. The signal quality and connection speed were excellent even when changing countries. Setting up was also very easy. It was my first time using an eSIM, and frankly, I was worried about how it would work! Turns out I needn't have been. Just follow the instructions.

Guest User2026-04-14

Excellent eSIM, worked perfectly in Montenegro, Bosnia and Herzegovina, and Turkey. High speed, excellent signal strength. Reasonable price. Highly recommended!

Guest User2025-11-04

We had internet throughout our entire trip to Greece, and the signal was strong. It was easy to install on my phone.
