This looks like a problem in ModemManager or the modem's driver. We are not responsible for neither of them, you should contact ModemManager's developers about this problem. Please attach the NetworkManager's log, the file ~/.xsession-errors and the dmesg command output for the to take a look.

Keep in mind that most modem's drivers are not prepared to suspend the modem's hardware. It is very advisable to unattach the modem from the computer before suspending.
