If you see these symptoms, stop troubleshooting your Telkomsel APN settings. You need to download the correct driver.
Since a dedicated "Telkomsel 500Mbps driver" does not exist, here is your actual troubleshooting checklist:
Not every USB modem can hit 500Mbps. The driver you download must match a modem with at least:

Without the correct driver, Windows will treat your high-speed modem as a generic “CDC Ethernet” device, locking you to basic LTE speeds.
1. Unlocks Maximum Speed (The 500Mbps Promise) The primary reason to install this specific driver is to enable Carrier Aggregation (4G+) . Without the proper driver, Windows or macOS often defaults to generic USB storage mode (CD-ROM mode). After installing this driver, my modem switched to NDIS (Network Driver Interface Specification) mode. I saw my connection jump from 40Mbps to roughly 280Mbps (YMMV depending on your tower). While 500Mbps is a theoretical peak in a lab, this driver is necessary to get past the 100Mbps bottleneck.
2. Solves "Modem Not Detected" Issues Out of the box, many Telkomsel 4G LTE modems (like the Huawei E8372 or ZTE MF920) only show up as a flash drive. This driver forces the modem to actually function as a network card. After installation, the "No Device" error in the Dashboard app vanished instantly. If you see these symptoms, stop troubleshooting your
3. Stable Connection Unlike generic RNDIS drivers from Microsoft, this specific driver handles signal fluctuations better. I noticed fewer disconnections during rain or peak hours (7 PM WIB). The ping dropped from 120ms to 45ms for Mobile Legends and VALORANT.
4. Easy Installation Wizard
Despite sounding technical, the downloaded file (usually a .exe or auto-run script) was straightforward. It takes about 90 seconds, and only requires one restart.
If you do manage to install a driver found via this search term, here is what usually happens: Since a dedicated "Telkomsel 500Mbps driver" does not
The most common reason for slow Telkomsel speeds is using the wrong APN. Forget drivers—configure this manually:
For very high-speed 500Mbps plans, some areas require the APN telkomsel-gprs with IPv4v6 dual stack.
