ussd

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?

问题 I'm a junior developer in Ionic platform, now I have a problem to send and receive USSD codes with that .... please help me is you know about that. 回答1: From what I have found on internet and tested, you can send USSD codes <a href="tel:YOUR_NUMBER" class="button button-positive">Call me? </a> and to make it functional you need to provide access in CONFIG.XML, simple add <access origin="tel:*" launch-external="yes"/> only disadvantage is: it will not directly dial your number rather open it

问题 I am facing an issue related to AT+CUSD command. On some Gsm modems, this command expects three parameters while on the others, it expects just two parameters. Moreover, different values of those parameters. I want to know that, how can I configure the Gsm modem so that this command can be executed in a uniform way on most Gsm modems.

问题 I am planning to create an Android App that will automate sending a users response to a USSD Menu. At a click of a button, the app will send the initial code, followed by the rest of the menu inputs. For example, the initial number is *143#, followed by 1, 1, 1, and a user PIN. I'd like to be able to automate that sequence of inputs so that the user won't have to input it on their own. I know that in Android Oreo, they implemented a USSD Callback using the TelephonyManager, where the Android
