Cons

Frequently asked questions
How much data do I get with NTT Docomo roaming?+
The roaming plan is unlimited, and 5G is part of the service. Hotspot sharing is also available, so you can share the connection with a laptop or tablet. The plan is sold as a carrier plan by NTT DOCOMO, INC. (Kabushiki-gaisha NTT Docomo).
How many countries can I use the service in?+
Coverage runs to 200 countries in a global footprint. That is a wide reach, though it does not match the very largest plans listed on the site, so check your full itinerary before you commit.
Is this an eSIM or a physical SIM?+
It is a carrier plan from NTT DOCOMO, INC. (Kabushiki-gaisha NTT Docomo), which is a carrier. That means the roaming arrangement sits with the mobile carrier rather than an app-based eSIM seller, so set-up follows the carrier's own process.
Who does NTT Docomo sell to?+
The service is aimed at short trips and long trips alike, and the carrier itself is based in Japan. It suits travellers who want their home carrier to handle roaming rather than buying a separate travel eSIM.
What support do I get if roaming goes wrong abroad?+
Support runs on chat and help centre, so help comes through chat and a help centre. There is no phone channel listed, which is worth knowing before you rely on it in a place with patchy connections.
When was NTT Docomo founded?+
The company was founded in 1992 and trades as NTT DOCOMO, INC. (Kabushiki-gaisha NTT Docomo). As a carrier rather than a marketplace reseller, it operates its own network and service directly.
Can I hotspot while using unlimited data?+
Hotspot sharing is included alongside unlimited data, and 5G is part of the plan. For a longer trip that means streaming and tethering on the same arrangement, subject to the plan's own terms.
