Inter Services Selection Board

You are not allowed to have mobile phones with you during entire duration of ISSB. The mobile phones are taken away from candidates and kept in safe custody till the last day. They are allowed to keep the SIM.
These phones are returned to all candidates on dispersal day when leaving the ISSB.
So…
if you want to stay in contact with your parents / family while reporting or leaving ISSB, you may bring the mobile along.
