Common questions
An eSIM is a digital SIM built into your phone. Instead of a plastic card, you install a mobile plan by scanning a QR code — no swapping, no store visit.
Instantly. The moment your payment clears, your QR code appears on screen and is emailed to you. Most travellers are connected within a minute.
Most phones from 2018 onward support eSIM and are carrier-unlocked. Run our free Compatibility check to confirm your exact model before buying.
Yes. Your eSIM runs alongside your physical SIM in dual-SIM mode, so you keep receiving calls and texts on your home number while using Velusim data.
You can install the eSIM as soon as you buy it — the validity period only starts counting once it connects to a network at your destination.
Our support team is available 24/7 and most issues are a quick settings fix. If we can't get you online, our refund policy has you covered.
