Which SIM does the BFT Multicom 500 take?
A standard size SIM (2FF), voice-capable, PIN lock off. The Multicom 500 is the bigger multi-resident panel in BFT's cellular family — more entries, same principle: one SIM makes every call.
Which network?
It's 2G hardware, so it needs a network still carrying 2G at the building — a shrinking list. On a panel serving a block, a multi-network SIM earns its keep twice: strongest network today, automatic re-registration when the 2G picture changes tomorrow.
Set a spend cap before handover — multi-resident call volume is real money.
Fitting the SIM
For the installing engineer, power down:
- Open the panel; the SIM holder is on the main board.
- Fit the standard SIM and lock the holder.
- Antenna connected before power, mounted high and clear.
First power-up
Allow registration, program resident entries per the manual, and test flats across the range — first, middle, last.
If it won't connect
- No registration: 2G at the building? Old-phone test at the panel.
- Individual flats fail: those entries' number format.
- Drops under load: signal margin — antenna work first.
