Can my smartphone use JB Voice eSIM? If I’m not sure, which one should I choose?

A:
Before using JB Voice eSIM, please make sure that your smartphone meets both of the following requirements:

  • Supports eSIM
  • Is compatible with docomo’s international roaming service

Please note that docomo’s international roaming service has device compatibility limitations. Therefore, even if your smartphone supports eSIM, it does not necessarily mean that JB Voice eSIM will work properly.

If you are not sure whether your smartphone supports eSIM, or whether it is compatible with docomo’s international roaming service, we recommend choosing the JB Voice Physical SIM Card instead.

A physical SIM card does not require eSIM support. As long as your smartphone has a compatible physical SIM card slot, you can use it. You can also borrow a compatible smartphone from a family member or friend to test or verify compatibility in advance, reducing the risk of being unable to use the service due to device compatibility issues.
