GSD stands for GS(GSM) D(Developers).
After the last free version we did in 2018, we decided to developing a commercial product.
Since then, it has been difficult to compete in the market with big software, we did our best until 2020 to bring an unrivaled product to market.
All the features in this product are different, there is quality of work, support and new features in this tool that make it unrivaled.
The gsm-developers team is working professionally on the GSD dongle.
