Can you double check the below mentioned points has properly done in you HL8518 module:

• Set the APN: AT+WDSS=0,”your-apn”,”apn-login”,”apn-password”
• Check APN : AT+WDSS?
• Subscribe to all indications : AT+WDSI=8191
• Check current indication subscription: AT+WDSI?
• Activate 3 user agreements
• Check user agreements setting
• Initiate a DM session : AT+WDSS=1,1
• Received “starting DM session” indication (+WDSI:4)
• Received indication (+WDSI:6), DM exchange occurred between the module and AirVantage
• Received indication (+WDSI:8), DM session is closed
• Initiate once again a DM session

Note: there is no DM exchange, no (+WDSI:6) indication
