How should I work > around this? This modem has an unsolicited signal (QSS) that shows the presence and status of the SIM. According to this signal, it seems that your SIM is detaching/attaching frequently (an unsolicited QSS 0 means SIM removed, while 1 means SIM inserted) ModemManager[27568]: <debug> (ttyUSB0): <-- '<CR>' ModemManager[27568]: <debug> (ttyUSB0): <-- '<LF>' ModemManager[27568]: <debug> (ttyUSB0): <-- '#' ModemManager[27568]: <debug> (ttyUSB0): <-- 'Q' ModemManager[27568]: <debug> (ttyUSB0): <-- 'S' ModemManager[27568]: <debug> (ttyUSB0): <-- 'S' ModemManager[27568]: <debug> (ttyUSB0): <-- ':' ModemManager[27568]: <debug> (ttyUSB0): <-- ' ' ModemManager[27568]: <debug> (ttyUSB0): <-- '1' ModemManager[27568]: <debug> (ttyUSB0): <-- '<CR>' ModemManager[27568]: <debug> (ttyUSB0): <-- '<LF>' ModemManager[27568]: <debug> QSS: status changed 'sim-removed -> sim-inserted ModemManager[27568]: <info> QSS: SIM swap detected then again ModemManager[27568]: <debug> (ttyUSB0): <-- '<CR><LF>#QSS: 0<CR><LF>' After this last status change, even other commands return with "SIM missing" ModemManager[27568]: <debug> (ttyUSB0): --> 'AT+CPIN?<CR>' ModemManager[27568]: <debug> (ttyUSB0): <-- '<CR>' ModemManager[27568]: <debug> (ttyUSB0): <-- '<LF>+C' ModemManager[27568]: <debug> (ttyUSB0): <-- 'M' ModemManager[27568]: <debug> (ttyUSB0): <-- 'E' ModemManager[27568]: <debug> (ttyUSB0): <-- ' ' ModemManager[27568]: <debug> (ttyUSB0): <-- 'E' ModemManager[27568]: <debug> (ttyUSB0): <-- 'R' ModemManager[27568]: <debug> (ttyUSB0): <-- 'R' ModemManager[27568]: <debug> (ttyUSB0): <-- 'O' ModemManager[27568]: <debug> (ttyUSB0): <-- 'R' ModemManager[27568]: <debug> (ttyUSB0): <-- ':' ModemManager[27568]: <debug> (ttyUSB0): <-- ' ' ModemManager[27568]: <debug> (ttyUSB0): <-- '1' ModemManager[27568]: <debug> (ttyUSB0): <-- '0' ModemManager[27568]: <debug> (ttyUSB0): <-- '<CR>' ModemManager[27568]: <debug> (ttyUSB0): <-- '<LF>' ModemManager[27568]: <debug> Got failure code 10: SIM not inserted according to this, ModemManager behavior is correct.

If I then Ctrl-C ModemManager, and open up a terminal program, and issue "AT+CPIN?"
