How to use a mobile provider's UUSD code service via an automated process?
问题 If I have a SIM card from a mobile operator - for example, Vodacom in South Africa, I can use their USSD services via dialling *111# . Then I can navigate the options via using my mobile phone keyboard. I would like to create a script that does this in an automated way. Is there a way to do this? I see this is possible on an Android application (Make USSD call in android). Is there a way to consume a specific mobile operator's UUSD service without first purchasing a SIM card from that
