为什么菜单“呼叫电话”选项不支持USSD代码? [英] Why USSD codes are not supported in menu Call Phone options?
问题描述
我尝试添加一个简单的USSD代码来检查余额*#123#并且我收到消息确认但在确认时我收到错误,说明我们必须使用键盘输入USSD代码。
我还尝试使用callto:或tel来自定义URI:但是我得到了同样的错误。
为什么我们不能从应用程序调用USSD代码?我真的不认为这可能是一个安全问题,因为用户总是必须确认电话,即使是电话号码。
谢谢
Hello i9ware,
"拨打电话"操作不支持USS代码, Windows Phone SDK中存在一个限制,其中PhoneCallTask无法调用GSM代码。
感谢您使用Windows Phone App Studio。
I tried to add a simple USSD code to check the balance *#123# and i get the message confirmation but when confirming i got an error stating we have to use the keypad for USSD codes.
I also tried to customize the URI with callto: or tel: but i got the same error.
Why aren't we able to call USSD codes from apps? I don't really think it could be a security issue because the user always have to confirm the call even if it is for a phone number.
Thanks
Hello i9ware,
The Call Phone action doesn’t support USS code, there are one limitation in Windows Phone SDK where the PhoneCallTask is not able to call GSM-Codes.
Thank for using Windows Phone App Studio.
