FAQs about the Tokyo eSIM
Will my eSIM work the moment I land in Tokyo?
Install your Teraroma Japan eSIM at home before you fly. The plan starts when your phone first connects to a local network in Japan, as long as the eSIM line and data roaming are switched on.
Which networks does the Tokyo eSIM use?
Our current Japan plans connect to NTT docomo, Rakuten Mobile, KDDI/au, SoftBank. The network your phone picks depends on the plan and local signal.
Do I need a separate eSIM for other cities in Japan?
No. Japan plans are country-wide, so the same eSIM works in Tokyo and anywhere else the local networks cover.
Can I keep my home number while using a Tokyo eSIM?
Yes. Teraroma eSIMs are data-only and run alongside your home SIM, so calls and SMS to your usual number keep arriving.
What if I need more data while I'm in Tokyo?
Top up your existing eSIM from the Teraroma top-up page. You don't need to install a new eSIM mid-trip.
