SIM card problems for CM11
As far as I can see there is many people with those errors on SIM card. It is weird, but I will try to debug them as soon as I can. I have not tested yet SIM card on it, and as you may know this are ALPHA builds of CM11. Of course don't expect a working perfect ROM!
Instead though, CM9 is working so much better than this CM11. Why because between CM9 and CM11 there are nearly 2 years! And devices has improved alot since then. Just test for have fun, take a screen and come back to your ROM. They are ALPHA builds!
