How BrilliSIM works
Three steps between you and mobile data in 150+ countries. No SIM shops, no surprise roaming fees, no waiting.
Step 1: Choose your destination
Search from 150+ countries or browse by region. Each destination page shows available data plans for different trip lengths.
Step 2: Pick your plan
Plans are priced by data amount and duration. Light usage (maps and messaging) typically needs 3–5 GB, moderate usage (social media and streaming) 5–10 GB, and heavy usage (video calls and tethering) 10–20 GB.
Most travelers use 5–10GB for a two-week trip. Plans start at €1.99, with top-up available on select destinations.
Step 3: Scan and connect
After purchase, your QR code appears instantly on screen. You can install with one tap on iPhone or Android, or scan the code with your camera. Setup takes about 60 seconds.
Install before departure — your plan activates on first network connection at your destination. See device-specific install guides →
What about my regular number?
Your eSIM runs alongside your existing SIM. Keep your home number for calls/texts and use your travel eSIM for data.
