* IMPORTANT: remember that these top-ups can only be used with a Phenix Mobile SIM card. A credit expiry date is associated with each top-up. If you top up several times, the furthest expiry date is applied. The expiry date is calculated when you activate the top-up. Once the expiry date has passed, any remaining credit is lost. Your phone number is valid for 4 months after the expiry date of the last credit purchase.

Get a Neosurf code in a "tabac" or "presse" shop and top-up your mobile by SMS or through your user account.

To top-up by SMS, send a SMS to 06 01 78 88 88, the content of the SMS is "NEO" followed by the Neosurf code.
Otherwise, access your user account and select Neosurf top-up.
