A quick pre-flight roaming checklist:

  • Note down your voicemail PIN , you'll need this if you check voice mail from overseas
  • Remember if you have any diverts in place, as these could run up charges, turn them off if need be
  • Check your phone's settings and decide if you want to turn off automatic downloads (data use) i.e. emails, calendar items, Facebook notifications, Twitter and location apps like Swarm.
  • Pack your charger and an adaptor!

Once you arrive

We will send you a TXT when you land. This confirms that you're connected and "roaming", it also includes helpful information and links about your destination.

Worth remembering:

  • The local telco's name will appear on your phone instead of ours.
  • You may be charged for receiving calls.
  • You may be charged for checking voicemail.
  • TXTs are 160 characters, if your message is longer you will be sending 2 TXTs.
  • Check on the dialling methods (i.e. making local calls in your destination or calling home) For example, calling an NZ number would be +6421 xxx xxxx instead of the usual 021 xxx xxxx.
  • If you're using an iPad, you can't receive TXT alerts about data use, so be sure to check My One NZ regularly.
  • If you need us, you call simply call 777 from most countries, as normal.
  • You can always buy more calling minutes, TXTs or data in My One NZ when you're overseas.
