Reviews: Europe 5G/4G eSIM | DayPass /Total | 500MB/day-total 30GB | 1-30 days | 24-hour billing | QR code

Bought the Europe eSIM package on Trip.com using my card this time, and the process was very smooth. Payment went through instantly without any extra verification or checkpoints, which made it quick and hassle-free. Activation was easy, and once I arrived in Croatia, the connection started working right away. The network has been stable for maps, messaging, and browsing. Overall, a convenient experience from purchase to usage. Good option if you want a simple and fast setup while traveling.

good to use and with esim there is no problem in switch the sim card. I recommend everyone should purchase it for traveling instead of a real sim card.

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.

Very stable network and date. Uses throughout the trip with no glitch. Evwn when I have a flight change and delay with layover or 24hrs. My data lastes throughout until the vwry last day this with juggles of WIFI providws at hotels and relative home. JEasy to use and not complicated though I was worried that I had faced challenges while wanting to top up my data..
