BG95-M3 NbIot or Cat-M1 connection without an APN.

Some other manufacturers of NbIot modules connect to their NbIot network does not require the input APN. Is it also possible BG95-M3.

it depend on the different operator ,

pls check the operator first , some operator does not need seting APN , e, g chinaMobile

if the operator need setting APN , with BG95 M3, by default , we need to setting APN mannually , but if some special customer , we can custom it , save APN to MBN file or NVRAM , before the module leaves the factory
