Why is a mobile number required?

A mobile number is required to open a Halocard account for security, verification and compliance purposes.

Halocard uses your phone number to send text messages for important alters including:

• One-time login codes
• Funds received to your Halocard account
• One-time 3D-Secure codes (when required for online purchases)
• New transactions on your Halocards
• Security notifications

Usage of VoIP Numbers

Halocard does not recommend using Voice over IP (VoIP) numbers as they are often unreliable. Using a standard, post-paid mobile service helps ensure you receive time-sensitive text messages and transaction alerts without interruption.
