Depending on the simcard you will need to add one of the following group to handle the connectivity:

Using simcards with public internet 
AT+IONAPN=1,"XXXXX” where “XXXXX” is the simcard APN
AT+IONIP="193.193.165.165","21009"

Using Oigo Connect services
AT+IONAPN=1,"connected-04"
AT+IONIP="173.27.224.9","21009"
