That's a good question, I'm not sure what to reply here. The COPS=0 request comes from a "Register automatically" user request, or as part of Simple.Connect(). The outcome of that operation is one single result, we don't report back "several results". In this case, the first "final" result we get from the modem is +CEREG: 3, so "denied", and from my point of view, that is the result that we should probably return, as we don't know what else will come afterwards. If a new "Register automatically" happens after that sequence, what does the modem do? i.e. if you run COPS=0 and we get the CEREG idle+searching+denied+registered sequence and just after that you run again COPS=0, does it go over all those 4 states again, or does it return +CEREG: 5 right away? -- Aleksander
