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!

A great SIM card for traveling, which turned out to be cheaper than roaming from my favorite carrier. Everything worked perfectly during the trip, with no issues... Overall, only positive impressions!
