NTT DOCOMO y eSIM de viaje en Japón

NTT DOCOMO en resumen

Wikipedia's list of 5G NR networks credits NTT Docomo with the first 5G NR carrier-aggregation deployment, in December 2020.

NTT Docomo's bands and technology

An eSIM can only use NTT Docomo 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.

NTT Docomo's coverage map

NTT Docomo 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 NTT Docomo's own network; a roaming plan may not get every technology it shows.

Who licenses NTT Docomo

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.

Los planes de nuestro catálogo que mencionan NTT DOCOMO

From the supplier record behind each package, 54 of the 129 plans we currently sell for Japan declare NTT DOCOMO 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.

Por qué los planes no especifican una red fija

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If NTT DOCOMO is weak where you are, try selecting KDDI (au) or Rakuten Mobile or SoftBank manually in the network settings, and keep data roaming on for the eSIM profile.
