PIN Cautions
Entering incorrect PIN three times locks PIN. To release locked PIN, enter PUK
(Personal Unblocking Key). For details on PIN, contact Customer Service. Entering
incorrect PUK ten times consecutively locks SIM Card to disable handset operations. In
that case, reissue of SIM Card at a SoftBank Shop (paid service) is needed.
