What type of SIM does MKR NB 1500 use?

The MKR NB 1500 is the only board with Narrowband communication so it is the perfect choice for devices in remote locations without an Internet connection. This board communicates via Narrow Band IoT (NB-IoT) which is a subsection of the LTE standard with a limited bandwidth (200KHz).

Thus, this board requires a SIM card from a compatible mobile carrier providing NB IoT service and the type of SIM this board fits is the 3FF (AKA Micro-SIM) format.
