No call from Cotulla reaches you until your number is registered with Securus Technologies, and at a unit where the average stay is near five months that setup is worth doing early. Create your phone account in minutes.

Calls out of Cotulla run on the Texas Department of Criminal Justice (TDCJ) inmate telephone system, billed through Securus Technologies. The part that surprises families is that nothing works until your number is registered on your side. He can dial correctly and still not reach you.
Go to texasprisonphone.com or call (866) 806-7804 and set up an account tied to the number you want him to reach. Until that is done, his calls to you will not connect.
The name on your government photo ID has to match the name on the phone bill. A number billed to a parent, a partner or a former roommate is the single most common reason a registration stalls.
Each call ends at 30 minutes. There is no monthly minute allowance, so the limit is per call rather than per month, and a longer conversation means calling back.
Phones are available from 5:00 AM to midnight. That is the system’s operating window, not a promise he has access at any given hour, since phone time also depends on his unit schedule and custody level.
Cotulla holds people in Transient status, and its own December 2020 PREA audit recorded an average stay near five months. Registration is tied to your phone number rather than to the prison, so setting it up now means a transfer does not cost you the connection and you are not starting over at the next unit.
No per-minute rate appears anywhere in TDCJ’s published material. Pages that quote a precise cents-per-minute figure for a Texas prison call are not sourcing it from TDCJ. Check the current rate with Securus directly when you fund the account.
TDCJ also does not publish how many numbers may be on a calling list. The widely repeated 10-name limit belongs to the Visitors List, which is a different list submitted by the inmate on Form RO-1, and confusing the two is an easy mistake.
Work through the causes in order. The number is not registered. The billing name does not match your ID. The account is out of funds. He is outside phone hours, or his custody status limits access. If none of those apply, the unit’s own line is (830) 879-3077.
Be careful with numbers you find elsewhere: (830) 965-4444 is published for the Briscoe-Cotulla Complex and rings the Dolph Briscoe Unit in Dilley, roughly 40 miles from Cotulla.

Phone CallsTDCJ does not publish a per-minute rate anywhere in its own material, so we will not quote one. Confirm the current cost with Securus Technologies when you fund the account, and treat any specific figure you see on a third-party page as unverified.
Phone CallsEach call is capped at 30 minutes. There is no monthly limit on total minutes, so the constraint is the length of any one call rather than how often he rings. Phones run from 5:00 AM to midnight.
Phone CallsYes, and this is the most common reason registration stalls. The name on the photo ID used to register has to match the name on the bill for that number. Sort that out before assuming the system is broken.
Phone CallsTDCJ does not publish a figure for the telephone list. The 10-name limit that gets quoted belongs to the Visitors List, which is a separate list the inmate submits on Form RO-1. The two are easy to mix up and they are not the same thing.
Phone CallsYes. Every call on the system is recorded, with one exception: a call to an attorney of record. Assume anything else you say is monitored.
