I'm surprised you are getting unicode errors, since normally the AT commands are done in plain ASCII. It'd be worth digging into the Simcom library, to see exactly what is being sent & received, e.g. try printing out the hex value of each character.
My best guess is that you may have an inadequate power supply, or poor connections somewhere.
