Common questions
What is an eSIM?
An eSIM is a digital SIM card built into your device. Instead of inserting a physical card, you scan a QR code to activate a data plan instantly.
Which devices support eSIM?
Most modern smartphones — including iPhone XS and later, Samsung Galaxy S20+, and Google Pixel 3 and later. Check your device settings to confirm.
How fast will I get my eSIM?
Instantly. After purchase your QR code is available immediately in your dashboard. No shipping, no waiting.
Can I keep my existing number?
Yes. Your eSIM runs alongside your regular SIM, so your home number stays active for calls and texts while the eSIM handles data.
What happens when my data runs out?
Top up your balance and purchase a new plan anytime from your dashboard. Your eSIM stays installed — no need to re-scan.
Is my payment secure?
All payments are processed by Stripe, a PCI-compliant provider. We never store your card details.
