We regret to inform you that it is not possible to transfer a phone number from a Mobal Voice+Data SIM Card to a Mobal Voice+Data eSIM (or vice versa).

Our network providers have specific limitations in place that prevent us from completing number transfers between the two product types and unfortunately, these restrictions are beyond our control.

Should you decide to proceed with your new order (to replace your Mobal physical SIM with a Mobal eSIM or vice versa) the new SIM / eSIM will be assigned a new phone number and your original phone number will be lost once the plan has been fully terminated.

If you have lost your Voice+Data SIM / eSIM and require a replacement of the same product type (and wish to retain your current phone number) however, please follow the instructions found here: Lost/Stolen Reports

Alternatively, if you have a Japanese phone number from another service provider (that you wish to transfer to a Mobal SIM / eSIM) or you would like to transfer your Mobal phone number to another Japanese service provider, please visit the following link: MNP Requests Guide
