Instructions for blocking, marking as spam or unblocking phone numbers on KDDI devices

Do you receive unwanted advertising calls and messages continuously and always at the least appropriate time?

You should know that your KDDI phone has the ability to block calls and text messages from contacts or phone numbers.

Once that phone number is blocked, you will no longer receive calls or messages. The caller will not notice since your phone number will always appear busy and you will not have notifications or interruptions.

Find here the guide to block or unblock phone numbers from your KDDI device among the 7 available models.

You can also mark phone numbers as “spam” or unwanted calls, in such a way that you will help other users who have not yet blocked those phone numbers to identify advertising calls.
