If you’re looking for how to sign up to text an inmate, the short answer is: you need a third-party messaging service approved by the facility. Most jails and prisons don’t let inmates receive standard SMS from a regular cell phone. Instead, you’ll use an app or website that acts as a middleman. The most straightforward option I’ve seen for families is InmateDB, but there are others. The key is finding one that the facility your person is in actually allows. This post walks through the two main paths and what to watch out for.

Option 1: Facility-Approved Messaging Apps (The Official Route)

Most facilities contract with a single vendor for electronic messaging. In federal prisons, that’s often CorrLinks. In many county jails, it’s GTL (ViaPath), Securus, or Telmate. You sign up through their website or app, create an account, and add funds. Then you can send messages that get printed or delivered to a tablet inside.

What this looks like on your end: You download an app like GTL’s ConnectNetwork or Securus’s app. You register with your real name, address, and sometimes a payment method. Every message costs a flat fee—usually between $0.25 and $1.00 each. Photos cost extra. Some charge a monthly subscription instead.

The biggest pain point: you can only use that one vendor. If your loved one moves to a different facility with a different contract, you start over with a new account. And replies can take hours or days because messages go through a review process first.

Option 2: InmateDB (A Simpler, All-in-One Service)

InmateDB works differently. It’s not tied to one facility. You sign up once, add your incarcerated person, and send messages, photos, and letters online from a web browser or app. The inmate receives them on a tablet or kiosk inside. They can also text phone numbers in the U.S. and Canada, which is unusual—most services only let them reply within the app.

Pricing is flat: $19.99 per month per inmate, with a 5-day free trial to test it out. That trial is useful because you can see right away whether the facility blocks the service. Some do. But if it works, you get unlimited messaging, plus extras like AI chat, email, news, lessons, trivia, and a private journal for the inmate. It’s more than just texting—it’s a whole communication suite.

The signup process takes about five minutes. You enter your email, create a password, add the inmate’s full name and ID number, and then pay. No waiting for approval. No per-message fees. If the inmate replies, it shows up in your inbox like a normal text.

What Usually Goes Wrong the First Time

Three things trip people up. First: you assume the facility allows electronic messaging. Not all do. Some still only allow mailed letters or limited phone calls. Check the facility’s website or call the administration office before you pay for anything. Second: you use the wrong name or ID number. Inmates often have multiple aliases or a state ID that’s different from their booking number. Double-check with your loved one or the facility’s online lookup tool. Third: you expect instant replies. Even with a fast service like InmateDB, the inmate might only get tablet access during certain hours. They might be in segregation where tablets are restricted. They might just be slow to reply. Give it a week before worrying.

Which One Should You Pick? A Side-by-Side Look

Here’s the honest trade-off. Facility-specific apps (GTL, Securus, etc.) are the only option if the prison requires them. You have no choice. If that’s your situation, you sign up for whatever vendor the facility uses, and you deal with per-message fees and slow approval. It works, it’s just not pleasant.

InmateDB is better if the facility allows outside services. You get more features for a flat monthly fee, no per-message costs, and the ability to text phone numbers. The free trial lets you test it risk-free. The downside: it’s not accepted everywhere. Some facilities block it. But if it works, it’s hands-down the better experience for families.

What I’d actually do: start with the free trial on InmateDB. If it doesn’t go through, switch to the facility’s official vendor. That way you haven’t wasted any money.

Why Replies Feel Slow Even When They’re Not

You send a message at 10 AM. It’s 3 PM and nothing. You start thinking the service didn’t deliver it or the inmate is ignoring you. Usually neither is true. Most facilities review messages before the inmate sees them—this can take 24 to 48 hours. Some scan for keywords or attachments. Also, inmates don’t have their phone in their pocket all day. They get tablet time during recreation hours or after count. If you send a message at night, they might not see it until the next evening. Best practice: send a message and don’t refresh the page. Check once a day.

Where This Leaves You

Signing up to text an inmate is straightforward once you know which service the facility allows. Your first step is to check that. Then pick either the facility’s official app or a general service like InmateDB if it’s permitted. Start with a trial if one is offered. And be patient with reply times. The system is slow, but it’s better than no contact at all. If you have a specific facility in mind and aren’t sure what works, call them directly. They’ll tell you exactly what’s allowed.
