When you receive a new AI-12 dashcam, the SD card is already inserted. The SIM card is either purchased from Surfsight, in which case it's already inserted, or purchased separately and needs to be inserted. There is a tamper-proof cover over the SIM and SD card slots that can be opened with the screw driver included with your dashcam. You may need to reinsert the SIM and SD cards, or insert new ones.
To install the SIM and SD cards:
Use the special screwdriver included in the box when you purchased the dashcam to remove the safety screws that lock it.
Insert the SIM and SD cards, as needed.
Only insert a microSIM card. If you insert a different sized SIM card, it can damage the dashcam.
