I tried to read MCC/MNC using “adl_plmnGetMccMncCode” function. It returns results which have nothing to do with reality. Fortunately, “at+cops?” returns the correct value (it returns it as one value, but for me this is acceptable).

Post the minimum compilable example which illustrates the problem you are seeing. … dp54032560

Sorry, I am an idiot. :frowning: For some reason it seemed to me that this function reads MCC/MNC from SIM card. I reread documentation and understood that the values are read from some string in GSM format.
