Mavic 3 and 4G dongle in EU

[k0200679]

I would like to share my experience with DJI 4G dongle that I have bought in March 2025.

Yes, it works in EU.
Yes, I have bought it in official EU DJI online store.
Yes, it's original Mavic 3 bought in 2022, NOT Mavic 3 Classic, Cine, Pro etc. But in official DJI store it says that 4G dongle is only compatible with DJI Mavic 3 Pro and DJI Mavic 3 Pro Cine.
Yes, you only need ONE 4G dongle. Your remote must be connected to WiFi Hotspot.
Yes, it works with Drone-H.... FCC mode.
Yes, it works with RC Pro
Yes it's DJI Cellular Dongle, NOT DJI Cellular Dongle 2 for DJI Air 3S DJI Air 3 DJI Mini 4 Pro.....
Yes it works with latest Mavic 3 firmware 20.00.1500 (March 2025)
Yes, it's another level of experience.
No, your cat still won't respect you.

Did you have to get a sim card to get it to work? If so, how much internet traffic does it consume?
Does it require subscription for enhanced transmission service from dji?
Hows the latency, is there a noticeable delay in the transmission?

Very interesting, thanks for sharing. Does the dongle increase the weight to over 900g (the C1 limit)?

Of course you need nano SIM card. It would be pretty difficult to calculate internet trafic needed because it will heavily depend on RC connection and 4G usage and will be different from time to time. I can only repeate what says on dji's FAQ page about dongle 2 "When fully relying on DJI Cellular Dongle for transmissions, the air unit will consume a maximum of around 1 GB during a 30-minute flight. The ground unit will consume a similar amount of data". Yes it requires dji subscription. First year is free, after that it's around 30€ per year. I still haven't tested it in flight, but on ground it feels promising. Lag is there, but it's more than OK. I will share my thoughts about lag after my first flight.

Hi there,
The LTE dongle has ports for TS5 4G antennas. How is the signal quality without them?

Thank you

Actualy, I have already ordered antennas last week. But even without them, signal quality is very decent. In about 40 minutes of solely 4G flight control, I had only one 5 seconds disconnect, that engaged automatic RTH. In general, there are small hiccups for 1-2 seconds every 2-3 minutes while flying full speed in city center

I received also a pair of antennas today! I will be testing them soon. I am pondering how to place them so that they don't interfere with DJI's gimbal protection mask. If you got any ideas please post a photo

BTW, did you manage to use FCC and 4G Enhanced transmissiin at the same time? I found it tricky, but doable. Wondering if that problem is only Finland related?

I have found a solution to have 4G Enhanced Transmission and FCC mode simultaneously for Mavic 3


After several days of testing I discovered very interesting detail.

It seems that DH emulates that drone is located in US. That’s why FCC is working, and that is why Enhanced Transmission is NOT working because Enhanced Transmission is blocked in states.

But there is 30 minute delay with DJI Enhanced Transmission servers and your remote.

If you switch off your remote and Drone for more than 30 minutes and switch them again, DJI Enhanced Transmission servers check your region again...

I am located in the Netherlands and haven't made any FCC mod... So I cannot give you feedback on that.
