SIM/RUIM is Perso locked - No service topic

I have looked into what this could mean, and finding that I have a pin on my sim but I dont

I can put my sim in my origonal device and works fine

this phone has been flashed with 2 roms both no signal only the 2nd rom was giving me this message at top of screen

one thing though, I am having to enter the sim unlock(phone lock from Three) code every time I reboot the phone, I obtained this code using the famous term emulater and running that specific string, this code enters fine and says

SSIM network unlock PIN, enters code, then gets - SIM Network unlock successful

any ideas
