日本におけるRakuten Mobileと旅行用eSIM

Rakuten Mobileの概要

Rakuten Mobile began commercial service on its 700 MHz "platinum band" on 27 June 2024, adding low-band coverage to its 1.7 GHz Open RAN network.

Rakuten Mobile's bands and technology

An eSIM can only use Rakuten Mobile 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.

Rakuten Mobile's coverage map

Rakuten Mobile publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Rakuten Mobile's own network; a roaming plan may not get every technology it shows.

Who licenses Rakuten Mobile

Mobile networks in Japan are licensed, and their spectrum assigned, by the Ministry of Internal Affairs and Communications (MIC). 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Rakuten Mobileを記載しているもの

From the supplier record behind each package, 42 of the 129 plans we currently sell for Japan declare Rakuten Mobile 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 Rakuten Mobile is weak where you are, try selecting KDDI (au) or NTT DOCOMO or SoftBank manually in the network settings, and keep data roaming on for the eSIM profile.
