Passing multiple USSD commands in a single call

问题

Say you have a USSD service which has the following structure:

Main menu -> *123#

Menu Item 1 -> Press 1 from main menu

Menu Item 2 -> Press 2 from main menu

Is there any way to dial a single command to go straight to Menu Item 1, for example *123#1 as opposed to dialing *123#, then waiting for the Menu, THEN selecting 1?

Hope the question is clear.

回答1:

Yes, you have to handle USSD auto dialing in your application. For example a user should be able to dial *123*2# to go straight to menu item 2. Check the SMSGH USSD Framework for implementation details here from line 69.
