Phone access is the single most important lifeline for someone in custody, and the most misunderstood by the people on the outside.
They call you; you cannot call them
There is no way to dial into a housing unit. The person in custody places calls during permitted hours from shared phones. If you miss the call, you wait for the next one. This is why keeping a phone charged and answering unknown numbers matters in the first days.
How calls are paid for
Two models dominate. In the first, the person in custody uses funds on their commissary or trust account. In the second, you open a prepaid account with the facility's telecom vendor and calls draw against your balance. Some vendors also accept collect calls, which are generally the most expensive option.
Rates have fallen substantially in recent years under federal caps on interstate calls, but per-minute pricing plus deposit fees still make this expensive relative to ordinary phone service. Fewer, larger deposits reduce the fee share.
Tablets and messaging
Many facilities now issue tablets for messaging, media and sometimes video calls. Messages are typically charged per message or per minute of connection, are not delivered instantly, and are reviewed before or after delivery.
Everything is recorded
Calls, messages and video sessions are recorded and retained. Prosecutors request them as a matter of routine, and recorded statements about the facts of a case appear in court regularly. Assume every word is evidence.
The narrow exception is properly registered attorney lines, which are privileged. Registration is not automatic; the attorney's office arranges it. Until it is confirmed, treat even attorney calls placed on the general system as recorded.
Common problems
A number can be blocked because it is unregistered with the vendor, because it is a mobile number the system cannot verify, or because it was flagged for three-way calling — which most systems prohibit and detect. Three-way attempts often suspend phone privileges.
If you stop receiving calls, check your vendor balance and account status before assuming something has happened. Suspended accounts and exhausted balances look identical to silence.
Practical advice
Set up the vendor account early, before it is urgent. Keep a written list of numbers the person may need, since phones in property are inaccessible and few people have numbers memorised. Agree in advance on a fixed daily call window so nobody spends the day waiting.
