Phone & SIM — connected before you leave the airport

Skinny is the quiet winner for students: it uses Spark's towers, so coverage is identical, but plans start around NZ$16 a month. The trade-off is no physical stores — everything is handled online, which is fine once your account is set up.

Postpaid contracts usually require a credit check or a New Zealand credit history you do not yet have, and they lock you in for 12–24 months. Prepaid plans give you the same data and calling for a similar price with no commitment, and you can switch providers the moment a better deal appears. Once you have six months of NZ banking history, moving to a postpaid plan with a subsidised handset becomes possible — but by then most students find they no longer need to.

1. 1

   Check your phone is unlocked and supports NZ bands

   Unlock it in Bangladesh before you fly — carrier unlocking from overseas is slow. New Zealand networks use standard 4G/5G bands that almost all recent phones support.

2. 2

   Buy the SIM at the airport with your passport

   Providers must record your ID. Take the smallest starter pack; you can pick a better plan once you know your usage.

3. 3

   Keep your Bangladeshi number alive

   Use a dual-SIM phone or an eSIM for your NZ line and keep the Bangladeshi SIM active with the minimum recharge — banks, NID services and family accounts in Bangladesh still send OTPs to it.

4. 4

   Move your two-factor authentication before you switch

   Change WhatsApp, Google, Facebook and your bank's verification to your NZ number, or to an authenticator app, while both numbers still work.

5. 5

   Register your number with the university and bank

   Do it the same day. Every later step depends on it.

6. 6

   Add home broadband only when you settle

   Fibre plans run NZ$65–90 a month and usually need a 12-month term. In a flat, split it — and check whether the property already has fibre installed before you order.
