Herramientas SIM

Herramientas SIM is an app that includes tools and information about the GSM system that allows you to connect to your telephone operator's networks. SIM cards have unique identifiers that are validated by an operator's network before they can connect to its wireless network.

Thanks to Herramientas SIM, you can access features and services specific to your operator. For example, when you insert a SIM card from a certain operator, your device can detect which operator it is, after which it might recommend that you download this operator's official app.

On Dual SIM devices, this app appears in duplicate. While the package name is com.android.stk for SIM1, for SIM2, the name becomes com.android.stk2.

The app may change its name depending on the SIM operator introduced to your device. Therefore, you may have to search for it by its package name if you can't find it under Herramientas SIM on your device.

So, if you want to update this app to help your device recognize your operator, or you have simply deleted it by mistake, download the Herramientas SIM APK here.
