DJI Cellular Dongle 2 - Add 4G Connectivity to Supported DJI Drones

In this review we test the DJI Cellular Dongle 2 and explain who benefits most from adding 4G connectivity to compatible aircraft. The bottom line: this accessory is for pilots who need reliable cellular links for Enhanced Transmission and extra connectivity features on supported models. It is especially useful for operators who want a fallback data path or remote monitoring where Wi-Fi or traditional RC links are limited. Our review focuses on fit, setup notes for each model, and practical tradeoffs when using a 4G network with a drone.

Key Features

• 4G network access: Enables DJI equipment to connect to cellular networks so pilots can use connectivity services when network coverage is available.
• Enhanced Transmission support: Provides an alternative transmission method that can extend range or maintain a link in challenging RF environments when 4G signal is strong.
• Direct insertion for Air 3: The dongle can be inserted directly into the DJI Air 3 body without an installation kit, simplifying setup for that model.
• Mounting kit requirement for Mini 4 Pro: Mini 4 Pro users must use the separate mounting kit that includes 4G antennas to ensure proper installation and performance.
• Service subscription note: After one year of active Enhanced Transmission service, pilots must follow in-app instructions to continue subscription access if required.

Who It's For

The Cellular Dongle 2 is aimed at professional and advanced recreational pilots who operate DJI Air 3, DJI Mini 4 Pro, DJI Air 3S, DJI Matrice 4T, or DJI Matrice 4E and need cellular-based connectivity as a supplement to standard links. It suits pilots working in remote inspection, long-distance monitoring, or operations where a secondary data path reduces mission risk.

Pilots who primarily fly in areas with weak or inconsistent 4G coverage should look elsewhere or treat the dongle as a secondary tool only, since Enhanced Transmission relies on strong cellular signal and may introduce lag or stutter. Mini 4 Pro owners must budget for the mounting kit that includes antennas.

Pros & Cons

Pros

• Provides cellular connectivity for enhanced features and remote data access.
• Direct insert design for DJI Air 3 makes installation fast for that model.
• Supports a range of DJI aircraft including industrial Matrice models for flexible use.

Cons

• Enhanced Transmission depends on strong 4G reception and can show lag or stutter in real use.
• Mini 4 Pro requires an additional mounting kit with antennas for proper use.

Our Verdict

The DJI Cellular Dongle 2 is a practical value add for pilots who need cellular backup or expanded connectivity on supported DJI models. It is worth buying for inspection teams and remote operators who fly where strong 4G is available, but casual flyers in weak-signal areas should treat it as optional. Overall, it delivers a useful alternative link and is particularly convenient for Air 3 users.

Frequently Asked Questions

Does the dongle require a SIM card?
Yes; if using a SIM you must purchase one from a local mobile network operator and activate it for the dongle.

Will Enhanced Transmission always be smooth?
No; Enhanced Transmission relies on a strong 4G signal and can introduce lag or stutter, so operate where cellular strength is high.

Do I need extra parts for Mini 4 Pro?
Yes; Mini 4 Pro users must use the mounting kit that includes 4G antennas for proper installation and performance.
