What's the difference between +CMGS and #CMGS?

The two commands

• +CMGS = Send Message (ETSI GSM 07.05 – Message Sending And Writing)
• #CMGS = Send Message (Custom AT Commands – AT Run Commands)

are basically the same. The main difference is, +CMGS requires to insert data after a prompt is received, while #CMGS does not. This makes possible to use #CMGS where +CMGS would not be such as:

• SMSATRUN service
• TCPATRUN service
• EvMoni (event monitor) service
