Legal analysis: There is no specific legal provision on how often you can make a phone call in prison. After the general criminals are transferred to prison for execution, they can talk to their families immediately after completing the relevant procedures, and some may have to wait for half a month or even longer. Some people can call home every week to say hello. In order to better reform prisoners, prisons all over the country have opened "home phones", and some people can usually make phone calls once or twice a month.

Legal basis: People's Republic of China (PRC) Prison Law.
