• About MVNO service

  Regarding the SIM card support status of MVNO services such as b-mobile SIM, BIC SIM, and BIGLOBE SIM, we have not confirmed the operation, so we cannot answer any questions.

  We recommend that you use EMOBILE terminals only for model changes. As new contracts are often not approved for bringing in, we do not guarantee them.

  Please note that we do not accept any returns or refunds for the reason that a new contract cannot be made.

About SIM-free models

SIM-free mobile phones, smartphones, and tablets are featured for overseas use, but we have not actually confirmed the operation in overseas countries, so you can reliably make calls and communications in each country. We can not guarantee that. If you want to know more about SIM-free, please check below.

Data such as supported radio frequency is described in the details of each product, so please purchase it after confirming whether it corresponds to the country you plan to use based on this.
