Remark: When the G2150I is set in “CG” class, the ME always make automatically a GPRS
attachment after init, so AT+WGPRS? always give +WGPRS: 0,0 for the parameter 0.
Note: Default value for mode 7 is 0; in this case, no automatic GPRS reconnection to new
operator is done when reaching border areas.
