If you’re looking to text inmates online, the short answer is yes, you can—through a growing number of private messaging services designed for correctional facilities. But the way it works is different from texting a free person, and the first time can be confusing. Here’s what you actually need to know.

How does texting an inmate work?

You send a message through a website or app, and the inmate reads it on a tablet or kiosk inside the facility. They can reply by typing back or sometimes by recording a short voice message. The message doesn’t go straight to your phone like a regular text—it goes to the service’s platform, and you check it there or get a notification. Some services also let inmates text real phone numbers, but that’s less common and usually costs more.

Is it the same as texting a free person?

No. The biggest difference is timing. When you text someone on the outside, you expect a reply in minutes—or at least within an hour. Inside a facility, the inmate might only get access to the tablet during certain hours, or they might have to wait for it to be passed out. A reply that takes 24 to 48 hours is normal. Also, messages are usually monitored and filtered. That’s not something to worry about if you’re not sending anything prohibited, but it does mean your message might be held up if it contains certain words or images.

What do I need to get started?

You need the inmate’s full name and their facility’s location—sometimes their inmate ID number. The service will verify that the person is actually there before your account goes live. Most services require you to create an account, add funds or choose a plan, and then wait for the inmate to be activated on their end. That activation can take a day or two. It’s not instant, so don’t panic if you don’t hear back right away.

Will the inmate actually get my message?

Usually, yes, as long as the facility allows the service and the inmate has access to the tablet. Some facilities block certain services, so check before you pay. Also, the inmate has to opt in—they usually sign up through the tablet. If they haven’t done that, your message will just sit in a queue until they do. That’s why it helps to tell them you’re sending something, if you can get a word to them another way first.

How much does it cost?

Prices vary, but you can expect to pay somewhere between $10 and $30 per month for unlimited messaging with one inmate. Some services charge per message or per photo. Others, like InmateDB, offer a flat monthly rate with a free trial period so you can test it before committing. Watch out for hidden fees—some services charge a setup fee or a fee to add funds. Read the fine print.

What if the inmate doesn’t reply?

There are a lot of reasons. Maybe they’re in lockdown and can’t access the tablet. Maybe they forgot their login. Maybe they’re not interested in texting that much. But the most common reason is that they haven’t activated their account yet. If it’s been more than a week, call the facility’s tablet support line (not the main switchboard) and ask if the service is active for that inmate. Don’t assume you’re being ignored.

Is this safe? Is it legit?

Yes, if you’re using a service that works directly with the facility. Stick to well-known providers that have been around for a few years. Scams exist, especially on social media where someone offers to “get a message to your loved one for a fee.” Don’t fall for that. Legitimate services contract with facilities and are transparent about their pricing. You can usually find reviews from other families online—look for real stories, not paid testimonials.

Where to start

If you want a service that’s straightforward and lets you send messages, photos, and letters online, InmateDB is worth a look. They offer a 5-day free trial for every new inmate, which gives you a low-risk way to see if the system works for your situation. The monthly plan is $19.99, and inmates can text phone numbers in the U.S. and Canada. No setup fees, no per-message charges. It’s one of the clearer options out there.
