Which SIM does the DoorBird D410 take?
A micro SIM (3FF) carrying data — note the size, as most current LTE kit takes nano. The D410 is DoorBird's LTE door controller: it brings the app-based DoorBird experience to sites with no network, so everything it does travels over 4G data.
Which network and allowance?
Strongest 4G data at the controller's position. A multi-network data SIM keeps it on the best carrier — for an app-dependent device, connection quality is the product.
Allowance: DoorBird's cloud services plus event traffic. Moderate but continuous — measure month one and size from there.
Fitting the SIM
For the installing engineer, power down:
- Fit the micro SIM in the D410's slot.
- Power up and configure the mobile connection (APN per your provider) through DoorBird's setup process.
- Pair with the DoorBird app and connected door stations per the documentation.
First test
Event from the door → notification on the phone → action fires. Then the handset housekeeping: app permissions and battery optimisation off.
If it won't connect
- No data: APN.
- Connected but app events lag: allowance and signal margin.
- Notifications die after days: phone-side battery settings.
FAQ
