Setting Up Phone Calls from Guadalupe County Jail: GTL AdvancePay, Hours, and How to Keep Calls Connected
Getting phone calls from jail is pretty straightforward once you know the schedule and how the system works with your phone line. Here's when Guadalupe County Jail phones are available, how to set up GTL AdvancePay, and the most common reasons calls drop—plus how to fix them.
Inmate phones at Guadalupe County Jail are available from 7:00 AM to 11:00 PM. That's your window for when your loved one can actually get to a phone.
The jail doesn't accept incoming calls for inmates. Staff won't patch you through, and you can't call in to leave a message - your loved one has to place the call out to you.
Outgoing calls can be collect or prepaid through AdvancePay. If collect calls aren't working with your carrier, prepaid is usually the easier option.
To set up a GTL AdvancePay account for calls from Guadalupe County Jail, call GTL toll-free at 1-866-230-7761. This is where you'll fund prepaid calling.
GTL phone support is available Monday through Friday, 6:00 AM to 10:00 PM CST. If you're in a different time zone, convert from CST before calling so you don't hit a closed line.
Weekend support runs Saturday and Sunday, 8:00 AM to 7:00 PM. Good to know if you need to fix something fast so you don't miss a call.
Disconnect Causes
- ✓ Don’t attempt a 3-way call - three-way calling can trigger the system to disconnect; if you need to include someone else, have your loved one call each person separately.
- ✓ Don’t try to transfer the call - avoid using any “transfer” feature on your phone system during the conversation.
- ✓ Don’t put the inmate on hold - if you have to step away, it’s safer to end the call and wait for another call back rather than using hold.
- ✓ Don’t use or answer call waiting - if another call comes in, let it go to voicemail; switching over can drop the jail call.
- ✓ Don’t use cordless phones - use a more stable option (like a corded line or a reliable cellular connection) to reduce dropped connections.
- ✓ Don’t press numbers on the touch-tone pad during the call - keypad tones can be read as an attempt to manipulate the system, so avoid interacting with the keypad once the call connects.
- ✓ Don’t stop the conversation for any length of time - even short pauses may disconnect the call, so keep some light back-and-forth going (a quick “I’m here” or “go ahead” can help).
If calls keep failing, contact GTL customer service at 1-866-230-7761. They can help with AdvancePay issues or connection problems. Support hours are Monday–Friday 6:00 AM to 10:00 PM CST, and Saturday–Sunday 8:00 AM to 7:00 PM.
