Egypt's Interior Ministry says pay phones will be installed in prisons for the first time.
An Interior Ministry statement on Thursday said the project is intended to let prisoners to contact their families as part of "the current ministry policy of abiding by human rights standards."
Egypt has a poor human rights record. Inmates have only been able to communicate with their families through visits when family members manage to obtain clearance from security authorities.
The phones are coming when dozens of ousted President Hosni Mubarak's associates have been jailed on charges of corruption and misuse of power.
Officials did not say precisely when the phones would be installed.
