Review: AT&T Mobley by ZTE (Mobile Hotspot / Connected Car)


The ZTE Mobley is a "Connected Car" device from AT&T that plugs into a vehicle's OBD-II diagnostic port, automatically creating a Wi-Fi hotspot whenever the ignition is turned on.

In other words - the Mobley exists primarily to keep passengers entertained with internet access while on a road trip.

Likely because average Mobley users might only use internet in a vehicle for a few hours per week , AT&T had paired the Mobley with an incredibly affordable  (just $20/month!) unlimited data offering. Now that that Connected Car Plan offering is no longer available, the sparkle of the Mobley device has dimmed significantly.

With a Cat 3 rating, the need to build or purchase an adapter so that you can keep the Mobley running, no 5.0GHz WiFi option, and a cap of 5 supported connections, this 'dumb' device is officially weak. Especially in comparison to the AT&T Unite Explore hotspot, or the brand new AT&T Nighthawk hotspot.

AT&T Offering Unlimited Shareable Data to Connected Cars

NOTE: The Mobley is frequently sold out, and AT&T reps have been known to try and substitute the Audiovox "Car Connection 2.0" instead, saying that it is equivalent. Don't be fooled - while the Audiovox also plugs into an OBD-2 port, it does not create a Wi-Fi hotspot and is only useful for vehicle diagnostics.

Quick Take

The Mobley is nothing special - but the $20/mo unlimited plan that you can get with it sure is.
