An excellent eSIM option at a very reasonable price. The connection was smooth, fast, and reliable the entire time. Setup was simple and didn’t require any technical effort. It’s perfect for travel or daily use. I would definitely use it again.

It worked great in Bosnia, Turkey, and Montenegro. No complaints. I recommend it. And the price is reasonable, especially with the discount from trip.

I didn’t know that Trip has this service. I usually used other applications for that. Trip lets you choose how many GB and for how long you want it, very flexible for very cheap prices.

Purchased this Orange Europe Travel SIM via CTRIP for the second time. The experience couldn't be any smoother. Easy to install via QR as always. Highly Recommended.
