Common reasons and quick fixes:

  • Billing address mismatch. Confirm the ZIP/postal code matches what your bank has.
  • 3-D Secure challenge. Some banks pop up a "confirm this purchase" screen — approve it in your banking app, then retry.
  • International purchase blocked. Openline charges from Bulgaria/EU; some banks flag EU merchants. Call your bank to allow it, or use a different card / Apple Pay / crypto.
  • Insufficient funds. Obvious but worth checking.
  • Wrong card details. Number, expiry, and CVV must match exactly.

If it still fails, try Apple Pay, Google Pay, PayPal, or crypto. All are equally supported.

Still stuck?

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
