Purchase

Pay with USDT or card

Pay with USDT straight from your wallet balance, or with Visa/Mastercard via Stripe — whichever you prefer. Confirm, and you’re done.

​
Activate in one click

No QR codes. No manual setup. After purchase, you receive an activation link — tap it once and your eSIM installs itself.
1

Tap the activation link

Right after purchase, you’ll get the link via in-app notification and email. Open it on the phone you want the eSIM on.
2

Confirm the install prompt

Your phone asks to add the eSIM — tap Allow / Add. That’s it, the eSIM is installed.

Turn on data roaming

When you land, enable Data Roaming for your eSIM line in Settings → Cellular/Mobile.
Most eSIMs activate within 1–2 minutes. Some destinations may take up to 10 minutes.

​
Manual installation (optional)

Prefer to install manually, or setting up the eSIM for someone else’s phone? You can also scan the QR code included in your confirmation email: go to Settings → Cellular/Mobile → Add eSIM → Use QR Code and follow the prompts.
