For information on the phone number you have been assigned and the dialing procedures your contacts will be required to use (when placing calls / sending SMS messages to your Mobal phone number), please refer to each of the guides below -

Your Mobal Phone Number

Once your Voice+Data SIM / eSIM has been fully activated, you will be assigned a standard Japanese phone number with a prefix of 070, 080 or 090.

The phone number will be provided to you in a confirmation email but it will also be available on your Mobal online account (MyAccount).

In the documentation provided however, you may notice that the Japanese phone number is in the international format (starting with the Japan country code prefix of 81 which replaces the leading zero).

Contacts that are calling you / sending you an SMS message from another Japanese phone number can simply enter your standard phone number beginning with the 070, 080 or 090 prefix.

If you have been assigned a phone number that starts with 8170… on your account for example, contacts with a Japanese phone number would just replace “81” with a “0” and so they would just dial 070 followed by the rest of your number.

Cellphone Numbers:

Contacts that are calling you / sending you an SMS message from an international cell phone number would be required to enter a plus symbol “+” followed by the Country Code for Japan (which is 81) and then they would enter the rest of your phone number with the leading zero removed.

If you have been assigned a phone number with a prefix of 070 for example, contacts calling you from an international cell phone number would dial +8170 followed by the rest of the number.

Landline Numbers:

For contacts that are calling you from an international landline phone number, it will not be possible for them to enter the plus symbol “+” prefix (as landline phones do not allow this).

These contacts would replace the plus symbol with the international dial out code (for the country they are calling from) and then they would enter the country code for Japan (which is 81) and then they would enter the rest of your phone number with the leading zero removed.

Please note that the international dial out code will vary depending on the country your contacts are calling from. To assist you further, we can confirm that the international dial out code for the U.S. is 011 and the international dial out code for most of Europe is 00.

If you have been assigned a phone number with a prefix of 070 and a contact is attempting to call you from a U.S. landline phone number for example, this contact would dial 011 81 70 followed by the rest of your number.
