i) for service option 4,
x = 1
ii) for service option 12,
x = 2 (default value)

b) On the terminating party, AT+COS=4,0,x where x is described above.
4) Establish the call:
a) Either use ATD to originate the call, or
b) use ATA to answer an incoming call (or set ATS0=1 for auto-answer)
5) When the “CONNECT” message is displayed, the data call is established and additional applications can
