I could not get that one to work.

/var/lib/gems/2.3.0/gems/phone-1.2.3/lib/support.rb:47:in
`class_eval': /var/lib/gems/2.3.0/gems/phone-1.2.3/lib/support.rb:47:
`@@{' is not allowed as a class variable name (SyntaxError)
/var/lib/gems/2.3.0/gems/phone-1.2.3/lib/support.rb:47: syntax error,
unexpected end-of-input
          unless defined? @@{:default=>true}

from /var/lib/gems/2.3.0/gems/phone-1.2.3/lib/support.rb:47:in `block in cattr_accessor'

And I wanted to ask -- did you figure out how to acknowledge the
SMSs? +CGNNA does not seem to do the job:

07912470338016...
AT+CGNMA=1
+CGNMA:ERROR=9

I believe I tried both... but for some reason I think you need to
paste back "acknowledge PDU"...?
