Reviews: Europe 5G/4G eSIM | DayPass /Total | 500MB/day-total 50GB | 1-30 days | 24-hour billing | QR code

Excellent Value with a strong signal. After pricing eSims on the open market this 15-day SIM card delivered excellent 5G speed in 3 EU countries seamlessly. My only note is to remember to buy a long enough day duration, as our trip was 16 days, and on day 15, it will deactivate, so maybe by the larger duration is available. 100% will use this service again.

Got another Greece eSIM for my friend as well, and it’s honestly amazing value around $1.3 for 100GB is hard to believe. The speed and reliability have been just as impressive, making it a perfect budget friendly option without compromising performance.

The internet is stable; however, the eSIM is intermittent. Sometimes the signal is lost while in use, and I have to turn the SIM off and on again to be able to use it.
