FAQ
Do NZ eSIMs require ID?
No — travel eSIMs are bought online and work instantly.
Signal at Hobbiton and the glowworm caves?
Matamata is covered; inside Waitomo caves there's none (fine outside).
How much data for a two-week road trip?
Navigation + social + photo backup runs ~1GB/day, so start at 15GB. Holiday-park Wi-Fi is slow — bring headroom.
