What 4g module is adapted to BPI R3 mini router?

Hi, if I need to use 4g mobile network with BPI-R3, do I need to buy 4g module separately? Is there any adapted 4g module available for purchase?

Hi, the R3 mini requires a 4g module to work properly with the 4g mobile network. I recommend you to use EM05 4g module, although it is suitable for R3 mini, but still need you to debug the driver in order to use it normally. Please check the steps below for details on how to use it:
