Notes:
- Access is valid for 12 months. However, Holafly reserves the right to verify the status of the service if it remains inactive for several weeks.
- eSIM is locked to a single device - Can't switch to a new device without purchasing a whole new eSIM.
- Hotspot and data sharing aren’t available with this benefit.
- Things like Lotto, TAB, ATpark, KFC and other apps/sites that require an NZ IP Address won't work on while using the data.
- Testing it, appears to route via Spain - speeds are fine - Things like ChatGPT, Claude, etc that don't work on some eSIMs seem to load without issue.
