ニュージーランドにおけるSparkと旅行用eSIM

Sparkの概要

Spark's 3G (UMTS) network was shut down in March 2026, according to Wikipedia's network-code list, and its 5G runs on the 2.3 GHz (n40) and 3.5 GHz (n78) bands.

Spark's bands and technology

An eSIM can only use Spark if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.

Who licenses Spark

Mobile networks in New Zealand are licensed, and their spectrum assigned, by the Radio Spectrum Management (MBIE) (RSM). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.

当店で取り扱うプランのうちSparkを記載しているもの

From the supplier record behind each package, 50 of the 66 plans we currently sell for New Zealand declare Spark as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.

プランが特定のネットワークを名指ししない理由

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Spark is weak where you are, try selecting One NZ manually in the network settings, and keep data roaming on for the eSIM profile.
