found a solution i think, write a new config like this:

local# sh run

Current configuration: ! service advanced-vty ! line vty no login ! gps device /dev/ttyACM0 gps baudrate default no gps enable ! ms 1 layer2-socket /tmp/osmocom_l2 sap-socket /tmp/osmocom_sap sim test network-selection-mode auto imei 000000000000000 0 imei-fixed no emergency-imsi no call-waiting no auto-answer no clip no clir tx-power auto no simulated-delay no stick location-updating codec full-speed prefer codec half-speed no abbrev support sms a5/1 a5/2 p-gsm e-gsm r-gsm dcs class-900 4 class-dcs 1 channel-capability sdcch+tchf+tchh full-speech-v1 full-speech-v2 half-speech-v1 min-rxlev -106 dsc-max 90 exit test-sim imsi 001010000000000 ki xor 00 00 00 00 00 00 00 00 00 00 00 00 no barred-access rplmn 262 01 hplmn-search foreign-country exit no shutdown exit ! end

an other question is if i let TX support disabled do the network see anything from me? or is it a real rx only mode? and is there any doc about the vty or the mobil app and if not where could i write my solutions for beginners like me?
