Reviews: 5G eSIM for 45 European Countries | Unlimited Data with Calls & SMS | 15 / 30 Days | Instant QR

I used it last time too, and I'm happy with the service, as it worked without any issues! It also sends SMS alerts about scams, so it's great for safety and can be used safely. However, it's important to be aware that the signal can be weaker inside buildings, so it's a good idea to use it with caution!

I used it in Serbia without any problems, even for 25 hours instead of published 24. Worked well, had no issues. It was very cheap and reliable. Recommend it.

This was my first time using an e-SIM, and it was for a trip to Europe. I was worried something might go wrong, but everything was fantastic; I always had internet. When you arrive, you just need to switch the SIM card settings and enable roaming. The SIM automatically connects to the best carrier in the region. I connected to Orange, Vodafone, and Turk Telecom.
