Moshi Moshi Plans
If you're looking for an affordable way to use your cellphone when travelling in Japan, you can get a Moshi Moshi eSIM from only US$4.50 (approximately ¥630) for 7 days usage.
To get a Moshi Moshi eSIM, you'll need to have an eSIM-compatible device such as the iPhone 11, Galaxy S20, Pixel 3 or later devices. You can then order your Moshi Moshi eSIM through the Airalo app with instant delivery direct to your phone. There's no need to queue at the airport or to register the Moshi Moshi eSIM with your ID, saving you lots of time.

Once you've ordered your Moshi Moshi eSIM, it will only activate when your cellphone actually connects to a supported network in Japan. This means the validity period will only begin when you actually land in Japan and turn your cellphone on.
Your Moshi Moshi eSIM works with the dual-SIM function on most modern smartphones. This means you can use your regular SIM card alongside the Moshi Moshi eSIM (e.g. to receive incoming phone calls and text messages on your normal phone number).
Alternatives to Moshi Moshi
The main disadvantage of Moshi Moshi is the fact you're getting a data-only service on the eSIM. You will not get a local phone number in Japan when you're using the Moshi Moshi eSIM in your phone.
If you'd like to call or text whilst you're travelling in Japan, you'll need to use your normal SIM card instead (on which international roaming fees may apply). Alternatively, you can side-step these charges by making your calls through WhatsApp or other similar apps.
If you're looking for a more fully featured SIM card with a local phone number in Japan (starting with +81), you could consider getting a regular prepaid SIM card upon arrival instead. This will involve some additional hassle (e.g. queuing up at the airport to get your SIM card, a registration process for the SIM card, etc) but it can be preferable and better suited for longer-term use in Japan.
Moshi Moshi Coverage
If you're using a Moshi Moshi eSIM, you'll have access to 4G mobile coverage in Japan. This is provided by the following partner networks:
Coverage Provider | Network Type | Coverage Area |
---|---|---|
KDDI | 4G LTE | Japan |
Softbank | 4G LTE | Japan |
There's no international roaming available on a Moshi Moshi eSIM. Therefore, you won't be able to use it outside of Japan. If you're planning to visit multiple countries on your trip, you may need to get a separate eSIM for the other countries you visit.
