Reviews: Europe 5G/4G eSIM | Daily/Total | 500MB/day-total 50GB | 1-30 days | 24-Hour Billing | QR code
Guest User2026-06-30
The eSIM worked perfectly after I downloaded and activated it. I had no issues with the installation or the connection. I was also able to extend my data after using up my original allowance, and the process was seamless. The additional data was activated right away, and I had no issues at all. Everything worked perfectly

I'm very happy with the purchase; everything is convenient and easy. They're always available, and they have city maps. This was my first time using this, but I'll be using it all the time now. Thank you for this opportunity.

I highly recommend this app! It's fast and cost-effective. When you're about to lose internet access abroad, just turn it on and you'll have internet again instantly. It saved me from almost getting lost and stranded overseas! I suggest buying it in advance without installing it, and then turning it on when you feel your mobile internet is about to disappear.

My family in the UK suggested Lyca, as they all use it. It’s a really good product, and I noticed it’s widely available in retail stores.
