RORO does not require or store any personal ID information.
Generally, personal ID information is not needed to use a RORO data plan.
However, due to local regulations, ID verification is necessary in China's Hong Kong and Chinese Taiwan. After arriving and activating your data plan in these regions, you will receive a message with instructions on where and how to register your information. This information is required by local authorities, not by RORO.
Other countries or regions covered by RORO data plans do not have such requirements.
