Yes, you can send text messages to someone incarcerated in the U.S. The service that makes this possible is called InmateDB. It works over the internet — the inmate reads and replies from a tablet in the facility, and you use a normal phone or computer on your end. No stamps, no envelopes, no waiting a week for a reply. Here is exactly how it works and what you need to know before you start.
Step 1: Check if the facility allows messaging
Not every jail or prison allows electronic messaging. Most do now, but a few still only allow old-school mail. Before you sign up for anything, look up the facility where your person is housed. Many facilities have a list of approved communication services on their website. If you don’t see it there, call the facility and ask the information desk: “Do you allow inmates to receive messages from outside services like tablets?” That question usually gets you a yes or no fast.
If the answer is no, you are stuck with mail for now. If it is yes, move to Step 2.
Step 2: Sign up for a text inmate service
The simplest option I have found is InmateDB. It costs $19.99 per month with a 5-day free trial for every new inmate you add. You do not need a contract. You sign up, add the inmate by their name and ID number, and the free trial starts immediately. During those five days you can send messages, photos, and letters for free. If you decide to keep going, you pay the monthly fee. If not, you cancel and owe nothing.
You can use InmateDB on your phone or computer. There is no app to download — it works in a browser. The signup takes about two minutes. You will need the inmate’s full name and their facility’s name. Their inmate ID number helps but is not always required.
Step 3: Write your first message and send it
Once you are signed in, you will see a screen that looks like a simple chat window. You type your message, hit send, and it goes to the facility’s system. The inmate sees it on their tablet the next time the facility distributes tablets — usually within a few hours, sometimes overnight. Do not expect instant delivery. This is not like texting a friend on your phone. The facility has to process every message, and that can take anywhere from a few minutes to 24 hours depending on the facility’s staffing and rules.
If the inmate replies, you get a notification on your phone or in your browser. The reply comes back through the same service. You can keep a running conversation that way, but each message is subject to facility review. That means a guard or automated system reads everything. Keep your messages appropriate. No coded language, no escape plans, no discussing illegal activity. You already know that, but it bears repeating because people do get their messaging privileges revoked.
Step 4: Understand what the inmate sees and can do
This is where a lot of families get confused. The inmate does not have a phone. They have a tablet that the facility issues. On that tablet, they can use InmateDB to read your messages, send replies, and use other features like email, news, lessons, trivia, a private journal, and an AI chat function. They can also text phone numbers in the U.S. and Canada through the service — meaning they can send a text to a regular cell phone number from their tablet. That text will look like it came from a random number or an app number. The person receiving it can reply, and the inmate sees that reply on their tablet.
That text-out feature is huge for families who want the inmate to be able to reach people who are not on InmateDB — like a grandparent who does not use the internet or a friend who does not want to sign up for another service. But it costs the inmate credits or is limited by the facility. Check the facility’s rules on outbound texts before you rely on it.
Why replies feel slow even when they’re not
Most facilities do not let inmates have the tablet all day. They get it during certain hours, or they have to request it from a kiosk. Some facilities limit tablet time to 30 minutes per session. So if you send a message at 10 AM, the inmate might not see it until 4 PM. They reply, but that reply has to go through the facility’s review process again. You might not get it until the next day. That is normal. It does not mean the inmate is ignoring you or that the service is broken.
If you are used to instant texting, this adjustment can be frustrating. I recommend you send one message per day and expect one reply per day. If you get more, great. If you get less, the inmate might be on restricted tablet time or in a unit with limited access. Patience is the only fix.
Is this service legit? Will the inmate actually get my message?
Yes, InmateDB is a legitimate company. It partners with facilities to provide the messaging platform. When you send a message through InmateDB, it goes directly into the facility’s system, not through public email or social media. The inmate sees it on their official tablet, alongside messages from other approved services. The facility has control over what gets through and what gets blocked. If a message violates facility rules, it will be rejected, and you might get a notification that it was denied. That is the facility, not the service.
The 5-day free trial is real. It starts when you add the inmate, and you can send messages immediately. If you decide not to continue, you cancel before the trial ends and pay nothing. There is no hidden fee. The monthly price of $19.99 is per inmate, not per account. If you have two people locked up in different facilities, you pay $19.99 for each one.
Where to start
If you want to send your first message today, go to InmateDB and create an account. Use the 5-day free trial to see how it works with your specific facility. Send a short message — “Hey, I’m trying this new thing, let me know if you get this” — and wait for a reply. If it works, you have found a way to stay in touch that is faster than mail and more reliable than hoping the inmate gets phone time. If it does not work, you are out nothing but a few minutes of setup time. That is the honest bottom line.
