Important: A SIM from Verizon, AT&T, or T-Mobile is required, but the carrier name alone does not guarantee that every SIM or data plan will be compatible.

Frequently Asked Questions

Quick answers about 4G data, SIM cards, power, remote viewing, recordings, and warranty.
01Do I have to buy a 4G data plan?+−

No. DC22 needs active mobile data for its remote 4G features, but you have two choices: use the included SIM with a data plan activated in the UBoxPro App, or replace it with your own compatible SIM and carrier data plan.

02Can I use my own SIM card?+−

Yes. You may replace the included SIM with your own compatible SIM and use your carrier’s mobile data plan. Supported U.S. carriers are Verizon, AT&T, and T-Mobile. Confirm that your SIM is active and compatible before switching.

03Which features require 4G data?+−

Remote Live View, GPS Tracking, Real-Time Alerts, and Two-Way Audio require DC22 to be online with active 4G data.

04Why is my DC22 offline?+−

Check the power connection first. Then check the SIM, available mobile data, and 4G signal. Restart DC22 and reopen the UBoxPro App. If it is still offline, contact LAMTTO Support.

05Why does DC22 turn off after I park?+−

Parking monitoring requires continuous power. Check the OBD-II power connection first. Some vehicles may have OBD-II power or compatibility differences.

06What if my OBD-II port does not power DC22?+−

Reconnect the OBD-II plug securely and confirm that the vehicle port is providing compatible power. If DC22 still does not power on, contact LAMTTO Support for vehicle-specific help.

07Why is Remote Live View slow or delayed?+−

Remote viewing depends on 4G signal strength and network conditions, so some delay can occur. Check the signal and available data, then retry or restart the device. If the delay is severe or persistent, contact support.

09Is Cloud Storage the same as the 4G data plan?+−

No. 4G data keeps DC22 connected for remote functions. Cloud Storage is a separate service, and its current features and pricing are shown separately in the UBoxPro App.

10Where are my local recordings stored?+−

Local recordings are stored on the microSD card while DC22 is powered and recording. Use the current device or App playback flow to review available recordings.

11Why does the remote video look less clear than expected?+−

Remote Live View can be affected by 4G signal and network conditions. Image clarity can also vary with lighting, motion, and distance. For recorded evidence, check the saved local recording when available.

12Does DC22 record the cabin as well as the road ahead?+−

Yes. DC22 is a dual-camera system with front and cabin views. Follow the installation guide to position the camera correctly for both views.

13How much does the 4G plan cost in the App?+−

Current data-plan pricing is displayed in the UBoxPro App before activation and may change over time. If you prefer, you can use your own compatible SIM and carrier plan.
