Reviews: European universal 5G/4G eSIM | Multi-network support, supports All AI & TikTok | 500MB/day - 50GB total | 1-90 days | 24-hour billing | QR code
Guest User2026-09-14
What I Loved: Fair 24-Hour Billing: Unlike other plans that reset at midnight, the 24-hour cycle started the exact moment I activated it upon arrival, giving me every minute of the 3 days paid for. Fast Speeds & Full Access: 5G connectivity was rock solid throughout the trip. Streaming TikTok videos and running AI tools went smoothly with zero network restrictions or throttling. Simple Activation: Scanning the QR code took less than two minutes. Good to Know: This specific plan is a 5GB hard cap total for the 3-day window—it doesn't refresh daily, and once the 5GB is gone, the service stops. It was more than enough for maps, messaging, and light browsing over a few days, but heavy streaming might burn through it faster.

I used it in the Netherlands, Belgium, and Switzerland. It worked perfectly and smoothly without any problems! The large data capacity was great; I could use Google Maps and other apps without worrying about data limits. Thank you!

The SIM card was excellent and worked in four EU countries. After flying from one country to another, the internet stopped working. I contacted support, and they responded immediately and explained how to connect to the internet in just a few minutes. The price is a bit steep, but I think it's worth it.

Worked fine. When it was connected to Vodafone it only used 4g, with Windtre I could use 5g too and it was much faster. I recommend selecting the carrier manually after the installation

The eSIM is very convenient to use. Connection is simple and straightforward. The downside is that it doesn't support 5G. My phone supports it, but this eSIM doesn't. It's only 4G+ and that's it.

An ongoing problem when used in mainland China,  service was not stable, requiring many a number of calls to support & a few resets, not the best experience. elsewhereinAsia, no problem though.
