In this FlexiSPY review, we will cover all of FlexiSPY’s SMS tracking features and make it easy for you to see why users go with this advanced phone spy software. We will also cover how to get started, how to download, install, and begin monitoring a device.

Product Features

The FlexiSPY SMS Tracker app boasts powerful spy software and a long list of capabilities that set it apart from other iPhone and Android spy apps. These features include:

Product Advantages

FlexiSPY SMS Tracker is a text spy app, but its features make it stand out as more. Therefore, we selected FlexiSPY as the best SMS tracker app on the market.

The first feature to stand out is the ability to spy remotely. Unlike other phone spy apps that leave easy-to-notice notifications in the system tray or notification pane, FlexiSPY can run as a hidden phone tracker. This means it hides everything that concerns the app on the device on which it is installed but still functions in complete anonymity.

Second is its ability to delete SMS remotely. Several other SMS tracker apps only let you spy on text messages or MMS, but leave users wanting more when it comes to being able to delete messages that may be vulgar or inappropriate – say, for your child for example. The FlexiSPY SMS Tracker notifies you when a certain keyword has been used in an SMS and allows you to delete it without a trace.

Third is the ability to send spoof SMS. FlexiSPY makes it possible for you to send a text message to any contact in the target user’s phone book as if it were coming directly from him or her. By sending a spoof SMS from the target device, you can solicit a response from anyone that would give you clearer indication as to what kind of information has been shared.

Another standout feature is the Alert Wizard. With FlexiSPY’s SMS Tracker you can receive alerts every time there is a swap in SIM card on the tracked device or when a preset keyword is used in an SMS.

One of most differentiating features of the FlexiSPY SMS Tracker App is that it does not require rooting, unlike the more advanced feature packages which are available for purchase on FlexiSPY’s monitoring software website.

Product Limitations

The most noticeable limitation of FlexiSPY is that you can only install it on one device per license purchase. In other words, you can only track one device at a time.

However, if the target changes phones or you wish to track another device, it is possible to deactivate the license and move it to another device as many times as you want during your subscription.

Features You Need

This feature lets you spy on text messages that are sent or received by the target phone. Also, no matter the length of the SMS message or the language in which it is written, FlexiSPY’s SMS Tracker app captures them effectively.
