In some cases, we are able to offer a Mobile Number Porting (MNP) option which would allow the transfer of a Japanese phone number.
However, the instructions / options available can vary depending on the specific product type.
Important Note: If you currently have a physical Mobal Voice+Data SIM Card and wish to transfer your number to a Mobal Voice+Data eSIM (or vice versa), please be advised that this will not be possible due to restrictions that are out of our control.
For additional instructions, please refer to the relevant guide below –
