It's been years since I used this module and I've always found it unreliable and eventually dumped it for the SIM800. I can't help you a lot here, as these results you're getting don't seem to be from my library. Still, the datasheet says to send AT+CMEE=2 to get more verbose errors, so you can try that and see if you can figure out the problem. Or just get a module like the SIM800 that'll save you all this trouble
