static com.android.internal.telephony.gsm.GsmMmiCodenewFromDialString(java.lang.String dialString, GSMPhone phone, com.android.internal.telephony.uicc.UiccCardApplication app)
Some dial strings in GSM are defined to do non-call setup things, such as modify or query supplementary service settings (eg, call forwarding). These are generally referred to as "MMI codes". We look to see if the dial string contains a valid MMI code (potentially with a dial string at the end as well) and return info here. If the dial string contains no MMI code, we return an instance with only "dialingNumber" set Please see flow chart in TS 22.030 6.5.3.2
