Speeds in central Paris were consistently fast. I uploaded videos and streamed music without buffering. For a city only trip, the performance was great. The connection stayed stable across cities. I didn’t notice random drops like I’ve had with other providers.
★★★★★
The app is clean and minimal
The app is clean and minimal, which I really appreciated. I could see my remaining data instantly without digging through menus. Used it daily around Lisbon and the UI never confused me.
★★★★★
Easy and simple activation
I bought the eSIM while boarding my flight to Barcelona. Setup took under 3 minutes and my plan activated once I landed at BCN. No QR-code, no APN. I was online before baggage claim which was exactly what I needed after a 6am flight
