I found SMS receive problem too. Can send, make calls but can t get message.
EDIT: I found that in top bar running text something about PIN and PUK code - before get network carrier. After that i can t get any SMS. I try to reboot and i got almost instant network signal and SMS work. After reboot didn t see message about PIN and PUK pincode. Pls try reboot your phone and take a note if you have message about codes (pin and puk)...
