Review on 🔌 NGFF(M.2) Key B to USB 3.0 Adapter with SIM 6pin Slot for WWAN/LTE Module - Enhanced Connectivity and SIM Support by Jaymai Alford

With few instructions but works great. I bought an Android car radio and wanted to set up a mobile data line with a SIM card. It works, but you need additional parts like an activated SIM card, 4G LTE module and antennas. I connected USB and installed mobile data. Connected easily. It doesn't work as a hotspot as mentioned in other reviews. Unless there are other modules that I don't know about. I hope this will be helpful for other Android car stereo users who are looking for built-in data function.
