Well Nitdroid is like that I think. It is still experimental; not very complete and lacks some important functionality. There exist some patches/tweaks I think that help with some problems. Hmm, it's a while since I booted into Sailfish/N9 but as far as I remember there was no SIM problems with my device. On Nitdroid there is the requirement that you have to have the PIN number of your SIM card disabled, because Nitdroid has not got the unlocking part implemented, but on Sailfish that should work fine.
