When you say "option doesn't kick in", what do you mean?  Do you  mean
that the kernel driver option.ko does not recognize the device?

When this problem occurs, what is the output of 'lsusb', and when you
replace the SIM, what's the output of 'lsusb'?  Can you grab some kernel
messages from 'dmesg' when you plug the device in and it doesn't work?
