Quick checklist: stay online without surprises

The make-or-break moment is often the first 30 minutes after landing: maps, transport, messages. Install your eSIM on Wi‑Fi before you travel and switch mobile data to the eSIM when you arrive. That way you're not dependent on airport Wi‑Fi and you avoid accidental roaming charges.

For typical use (maps + messaging + light social media), 1–3 GB per week is often enough. If you tether for a laptop, take video calls, or stream daily, aim for 10 GB+ or a plan with fair-use throttling instead of a hard cut-off.

• Networks: Vodafone (5G)
• Offline maps: download the area in Google Maps, Maps.me (offline for rural) while you're on hotel Wi‑Fi.
• On the move: Uber, Ola + WhatsApp, iMessage work well on low data — video and app updates are usually the real data drains.
• Common weak spots: Milford Sound road from Te Anau to the fiord · Fiordland and Paparoa national park trails
• City context: Auckland: Good coverage; CBD and suburbs well-connected. · Queenstown: Good in town; skifields and bungee sites variable; Remarkables peaks lose signal.

Phone setup tip: keep your primary SIM active for calls/SMS (so 2FA codes can arrive), but turn off mobile data on that line. Set the eSIM as your data line — it prevents accidental roaming on the wrong SIM and keeps WhatsApp/banking flows more predictable.
