Advantages of Using CDJapan Rental SIM Card

As our service is rental, we are able to provide you some advantages that you cannot get from prepaid, sellout SIM card providers.

1. Get a refund when your device was not compatible with the SIM card.

In case your device was not compatible with our SIM card, we offer an option to return it within 2 days to apply for a refund. None of prepaid SIM card sellers give a refund even if your device was not compatible with their SIM card.

2. Flexible rental periods available for both short term and long term visitors.

Our prices are calculated based on the rental period and not on the data amount used. This allows us to provide flexible rental period to you. Also, we offer an option to extend the rental period in case your itinerary changes.

3. If you have any question or problem, contact us and we will help you.

We will reply to your messages as soon as possible in English.
