Using eSIM on this trip abroad was incredibly convenient. Installation was simple and quick, and I could access the internet immediately upon arrival. The network was stable and fast, making it easy to check maps and send messages. The price was also very affordable. I will definitely buy it again next time I travel abroad!
This is my third repurchase. I buy it before I go abroad, and I can activate it directly upon arrival, which saves me a lot of trouble. The network has been very stable these past few times, so I will continue to buy it when I travel abroad again.
