Re: +cme error : unable to get control of the required modul

It looks that you have problem with your power supply, if module work ok without SIM.

When module tries to regigister itself to the network it can surge up to 2A, but if your power supply is not capable to deliver that amount of current the module will reset. Try to place the electrolytic capacitor of 1000 uF on your power supply line.
