Frequently asked questions

How much does a Southeast Asia eSIM cost?
Plans start at $2.89 for 1 GB. 19 plans are available, delivered instantly by email after purchase.
Can I pay per day?
Yes — day passes start at $2.95/day and you choose exactly how many days you need (1–365) at checkout.
When does my plan start?
The validity period starts when your eSIM connects to a supported network at your destination — not at purchase. Install it before you fly and it activates on arrival.
How do I install my eSIM?
After purchase we email you a QR code. Open Settings → Add eSIM, scan the code, and turn on data roaming for the new line when you land. It takes about two minutes.
Can I add more data later?
Yes — open My eSIMs in your account and tap 'Top up data' on your active eSIM. No new QR code needed.
