Advances in technology have led to some interesting apps, for example, SMS Peeper. This is a message spy app which allows viewing the text messages of any phone number without having access to the target device. In this article, we will do an in-depth review on SMS Peeper to see does it really work like advertised. We will also compare it to a great text message spying app called KidsGuard Pro. Find more details in the following part.

What Is SMS Peeper

SMS peeper is a service that you can use to monitor someone else's text messages. It can track both incoming and outgoing text messages all without the other person's knowledge. You can use SMS peeper without having to download the app on the target device. It was one of the earliest tracking solutions to be introduced in the market.

This app will present 100 records of text messages, 50 of them are outgoing and the other 50 are incoming. Along with the text messages, you can check the phone number of senders or recipients. In the following part, we are going to be looking at SMS Peeper reviews, how it works as well as its pros and cons.

What Is SMS Peeper

How Does SMS Peeper Work

To use SMS peeper, you just need to know the target phone number and follow the steps below. It will access the SMS database archive and present the found results one by one.

Step 1. Visit the SMS Peeper website and enter the country, phone number that you want to track and your email address. Once you click "Get Messages" the service will start to populate all messages on that phone number.

Step 2. Then, you will be able to see up to 100 messages (50 incoming and 50 outgoing). To read a message, just click on "Show Messages".

Get Messages

Step 3. You will then be required to enter a code. Click on "Download code" and follow the steps below to get the activation code:

  • Click the "Download Code" on the left. You will be redirected to the page with the code (

  • Click the "Download File" black button.

  • Choose from a list one offer/survey and fill it in with your valid information. Downloading a file with the code will start automatically after completing the offer/survey.

  • Enter downloaded CODE in the box on the left and click on "Show messages".

Step 4. Once you've entered the code you should be able to see the message including the name of the sender or recipient and the date and time the message was sent.

Reasons to Choose SMS Peeper

As a successful text monitor app, SMS Peeper is popular for some reasons:

  • The steps are quite easy to follow. You don't have to install the app on the target device or touch it in order to intercept text messages.

  • It's free to use. You just need to complete a few surveys to get the final results.

  • You don't have to register any accounts.

  • The messages spying technology is hardly to be discovered.

Reasons to Avoid SMS Peeper

However, SMS Peeper will work very well to populate the messages from the provided phone number until you need to enter the code to read the messages. This is where most users have been stuck, for lack of a better word. Most users report that when they click on "Download Code" instead of getting the code, they are expected to take surveys or download other programs. Some people even say that after downloading the programs, taking the surveys or purchasing something, the code they got didn't work.

Does SMS Peeper Really Work

Also, you will be required to fill your name and email address to complete the survey, which means your personal information may be exposed. After testing SMS Peeper, we have received a few spam emails. And we have also encountered database errors, which showed a blank screen without generating any results.

Except all the mentioned drawbacks, SMS Peeper only works to spy on text messages. If you need to spy on other data such as contacts, call history, social app chat history, location and more, then KidsGuard Pro is the best option.

Find out the Best SMS Peeper Alternative

If you are looking for a better way to track someone else's SMS, a method that will not require you to jump through numerous hoops to get the messages, you should consider KidsGuard Pro. This program is designed to be the ultimate monitoring tool, working behind the scenes on the device to provide you with as much information about the device as you need.

Once the app is installed, you can monitor the text messages as well other data remotely.
