How to Set Up 4G Cellular on Your MobileMule DVR – Rear View Safety

Setting up 4G cellular on your MobileMule DVR allows it to transmit GPS location and live video to the MobileMule Live portal from anywhere with cellular coverage. This requires a SIM card with an active data plan installed in your DVR.

Before You Start

Make sure you have:

A SIM card with an active data plan installed in your DVR
Your carrier name (T-Mobile, Verizon, AT&T, or other)
Your DVR login credentials (default username: ADMIN/password: 888888)

APN Settings by Carrier

You will need your carrier's APN to complete setup. Here are the most common ones:

Carrier	APN
T-Mobile	fast.t-mobile.com
Verizon	vzwinternet
AT&T	broadband
Other	Check your carrier's website for APN settings

Steps

Log in to your DVR (username: ADMIN/password: 888888)
Go to Peripherals > Cellular
Set Cellular to ON if it is currently off
Set Type to FDD-LTE
Enter your carrier's APN from the table above
Leave Center Num as *99#
Set Netmode Sel to AUTO
Set Auth Mode to None
Press Save

Confirm Your Connection

After saving, press the blue Info button on your remote to open the System Info screen. Look for these values:

Field	What You Want to See
4G-State	Successful
4G-Sign	A value greater than 0 (higher is stronger)
Center-L	SUCCESSFUL

If 4G-State shows Successful and Center-L shows SUCCESSFUL, your DVR is connected to the cellular network and the MobileMule Live portal.

Common Issues

4G-State shows NO DIAL: Your APN is likely incorrect. Double-check the APN for your carrier and re-enter it. Make sure there are no extra spaces in the APN field.

4G-State shows Successful, but Center-L shows NO LINK: Your DVR is connected to the cellular network but cannot reach the MobileMule Live portal. Your data plan may not be fully activated yet. Contact your carrier to confirm your account is active and data has been enabled.

Weak 4G signal: If 4G-Sign shows a low value, your vehicle may be in a low-coverage area. Move the vehicle outside to an open area and check again.

SIM not detected: Power off the DVR, remove the SIM card, and firmly reinsert it until it clicks into place. Power the DVR back on and check the System Info screen again.
