Try this
- Confirm billing information is correct.
- Try another payment method if available.
- Disable VPN temporarily if checkout fails repeatedly.
- Contact your bank or card provider if the transaction is declined.

Contact 4S support through support@4s.net, a Zendesk support ticket, or Zendesk live chat. Do not reply to hi@4s.net; it is an automatic order and installation email sender.
If you were charged but did not receive an eSIM, do not purchase repeatedly. Contact support with the charge screenshot.
