GSM SIM Utility

Even though your mobile phone is an important personal object, it too is at risk of getting damaged, lost or stolen. Luckily, various applications let you backup data just to be on the safe side. GSM SIM Utility is such a toolset that you can use to backup the information on your SIM card so you won’t lose it in case your phone gets stolen or broken.

Lightweight and easy to use

The application displays a comprehensive interface which makes it easy to use by just about anyone with basic computer skills and the knowledge of how a SIM card functions. To be able to use this tool, you need to insert the SIM into a card reader then connect it to your computer. From then on just launch the application and create your backups.

Transfer your contacts list between your phone and PC

The application provides you with tools that make it possible for you to not only read information from the card but also to write to it. This way, you can backup contacts from your addressbook and save them on your computer, as well as you can add new contacts or transfer multiple ones to a new card. To add a contact to the SIM, all you have to do is double click on an entry and just type in the name and phone number. You can add contacts to both normal and STK phonebooks in the same simple manner.

Enhance your mobile phone with custom ringtones

Backups can be created for messages as well and they can be edited in the same way. GSM SIM Utility enables you to copy and replace original data found on your card or append the new information after the original one.
Besides adding contacts and editing messages, you can even create custom ringtones using this tool. You can compose RTX musical notations and choose their tempo along with the number of cycles.

To end with

In closing, GSM SIM Utility is a reliable tool that can create phone backups for both contacts and messages but it is an application that has limited functionality and compatibility. And this because it is a tool created a considerable time ago and since then things have evolved out of its reach.
