What your New Zealand number looks like
A New Zealand mobile number is mobiles start 02 (e.g. 021/022/027), 9–10 digits — for example 021 234 5678 / +64 21 234 5678. If what you see doesn't match that, you may be reading a different field (such as the ICCID/SIM serial) rather than your number — re‑check with the method above.
