Seems like Merlin U630 does not accept manual network selection (at least that's my conclusion trying to set it up manually in minicom - and yes, I checked the strings matched the ones in AT+COPS=?).
Default situation should be NM sending AT+COPS=0 (automated GSM operator selection). If the user wants to select the network, then AT+COPS=1,0,"%s" should be used, as it's more likely that the user will insert the long string (in my case "P OPTIMUS") than the numerical value (in my case "26803").
OK, feature needed for NM.

AT command set reference for this: http:// gatling. ikk.sztaki. hu/~kissg/ gsm/at+ c.html
Should I try to hack up a patch later?
