Dash Cam SIM Cards and Connected Dashcams

A SIM card is only useful in a dash cam with an LTE modem or compatible LTE accessory. Match the network bands, SIM size and data plan before you buy.

A dash cam SIM card enables mobile-data features only when the camera has built-in LTE or a supported cellular module. It does not replace the microSD card that stores footage. A dashcam with SIM card connectivity can upload events, report its location or provide remote viewing, depending on the model and service plan.

Common questions

Questions before you buy

Can I put a SIM card in any dash cam?

No. The camera needs a built-in LTE modem or a manufacturer-approved LTE accessory. A microSD slot is for storage and cannot provide mobile connectivity.

Does a dashcam with a SIM card still need a memory card?

Usually yes. The memory card holds the main recordings, while the SIM provides a data connection for selected cloud or alert features.

What type of SIM does a connected dash cam use?

It depends on the model. For example, BlackVue specifies a nano SIM for the DR970X-2CH LTE Plus, so confirm both physical size and carrier compatibility in the manual.

Will a dash cam SIM work when the car is parked?

Only if the camera also has continuous parking-mode power and network coverage. Hardwiring or a compatible battery pack may be required.

How much data does an LTE dash cam use?

Usage varies with live viewing, uploads, alerts and video quality. Check the camera's data settings and your provider's usage reporting rather than assuming a fixed allowance.
