@EndruK had a communication issue with the module and it solved it by forcing the baud rate for the AT communication.

I planned to integrate his suggestion in the library when I will have a module in hands.

Can you try this : #48 (comment) ?

As mentioned in the README, the project is no longer maintained as my module is broken. Thanks for reporting the issue.
