Therefore, a research was conducted which aims to describe the implementation of mobile SIM in improving public services by the Regident Unit of the Traffic Police of Garut Police, the efforts of the Regident Unit in optimizing these innovations, as well as the factors that influence it. This research was conducted with a qualitative approach that focuses on optimizing mobile SIM located in Garut Regency, data collection techniques by interviewing, observing and reviewing documents, data validity using data triangulation with primary and secondary data sources and data analysis techniques in the form of data reduction, presentation. data, and drawing conclusions. The results of the study found that the optimization of mobile driving licenses in improving public services by the Garut Police Traffic Police Regident Unit analyzed by management theory and Article 21 of Law Number 25 of 2009 were appropriate to be implemented at the Garut Police. The implementation of a mobile SIM is quite good with the fulfillment of the indicators contained in Article 21 of Law Number 25 of 2009. However, there are still obstacles in terms of waiting room facilities, costing, and guaranteed service certainty, especially in determining the schedule for reaching the region. remote areas of Garut Regency. Analysis of the efforts of the Regident Unit in optimizing the mobile SIM has been going well, but it needs to be improved in the function of supervision and organization.
