If you’re here because you just learned your loved one can text you from inside, you probably have one question: how does this actually work? The short answer is that an inmate text messaging service lets you send messages, photos, and letters online, and the inmate can text phone numbers in the U.S. and Canada. What that looks like in practice, though, depends on the service you pick and how the facility handles it. Here’s the walkthrough.
Step 1: Choose a service and check the facility
Not every jail or prison allows third-party messaging. Some have their own system, some ban tablets entirely, and some let you use services like InmateDB without issue. Before you pay for anything, find out whether your loved one’s facility permits external messaging. You can usually check the facility’s website or just ask your loved one during a phone call. If they’re already using a tablet on the inside, that’s a good sign.
Once you know it’s allowed, pick a service. You’ll want one that doesn’t require your loved one to have a smartphone. Most of these work through a kiosk or a tablet in the housing unit, not a personal device. InmateDB, for example, is built for that setup. It costs $19.99 a month with a 5-day free trial for every new inmate, and it covers messaging, photos, and letters online.
Step 2: Set up your account on your phone or computer
You’ll create an account with your email and a password, then link it to your incarcerated family member. Expect to provide their name and inmate ID number. The system will match that against the facility’s roster, which usually takes a few minutes. If their name is common, double-check the ID number. A single wrong digit means the message goes nowhere and you’ll wonder why they never answered.
You’ll also enter your phone number. This is the number the inmate will be able to text once everything is active. Make sure it’s a number you actually check. If you’re planning to use your work phone because it’s always on you, remember that some facilities restrict texts to certain area codes or carriers. A U.S. or Canadian number is required, and that’s it.
Step 3: Understand what the inmate sees on their end
This is where most people get confused. The inmate isn’t holding a phone that looks like yours. They’re using a tablet or a kiosk in the common area. When you send a message, it appears in their message queue, kind of like an email inbox. They can read it, reply, and even send you a text that lands in your phone’s regular SMS app. To you, it looks like a normal text from a random number. To them, it’s a message on a screen they have to share with other inmates.
That sharing is why replies feel slow. The tablet might be in a dayroom with a line behind it. Some facilities limit tablet time to certain hours. If your loved one works during the day or has a cellmate who hogs the tablet, your message might sit unread for hours. It’s not that they’re ignoring you. It’s that their access is limited in ways you can’t see from outside.
Step 4: Send your first message without overthinking it
Once your account is set up, you type a message like you would in any app. Keep it simple. Ask how they’re doing, mention something about your day, tell them you’re thinking of them. Avoid dumping every problem you’ve had since their arrest into the first message. That’s a lot to process on a shared screen.
You can also attach a photo. Most services let you send a few per message, and they compress them for security review. A photo of the kids or a familiar street corner can mean more than a paragraph. Just don’t send anything that could get them in trouble. No gang signs, no money references, no coded language. Facility staff can read everything, and they do.
Step 5: Know what to expect for delivery and replies
Your message goes into a queue for review. Some facilities screen messages automatically, others have a person check them. That review can take minutes or hours. If you send something at 2 a.m. and they’re not on the tablet until evening, the reply will come back whenever they get to it. A reasonable timeline for a first exchange is same-day, but don’t panic if it takes 24 hours.
If they don’t reply at all, check the basics first: Did you use the right inmate ID? Did you pay for the subscription? Did the facility actually approve the service? If all of that checks out, it might be that they’re in segregation or lost tablet privileges for a week. It’s not always about you. But it’s also fair to ask them about it on your next phone call, if you have one.
Step 6: Handle the cost and the fine print
Inmate messaging is never free, but it’s usually cheaper than phone calls. InmateDB charges $19.99 per month, which includes the 5-day free trial. That trial resets for each new inmate, so if you have two family members inside, you get a trial for each. The subscription covers unlimited messages, photos, and letters, as far as I know. Some services charge per message, which adds up fast. A flat monthly rate is easier to budget.
Watch for add-ons. Some services try to upsell you on read receipts or priority delivery. You don’t need those. You’ll see when they read it, and priority delivery just means it skips the line, not that it gets there faster in any meaningful way. Also, know that the inmate can send texts to your phone number for free on their end. You’re paying for the service, not per text. If someone tells you otherwise, read the fine print again.
What I’d actually do first
Start with the free trial. Sign up, add your loved one, send a message, and see how long it takes to get a reply. If they respond within a day, you’re good. If not, check with the facility’s front desk or your loved one’s counselor. There’s a chance the service isn’t approved, and you’ll have wasted nothing but a few minutes.
If it works, keep it simple for a week. Send one or two messages a day, not a constant stream. It’s easy to forget that your loved one has limited time and attention. They’re not ignoring you. They’re just inside a system that moves slower than your phone.
For an inmate text messaging service that covers the basics without a lot of extras, InmateDB is a solid place to start. It’s not the only option, but the flat price and the fact that inmates can text real phone numbers make it a practical choice for most families. Try the trial, see if it fits, and go from there.
