Methods

There are two methods, sendUssd & sendAdvancedUssd. The sendUssd runs the ussd normaly and supports multisession USSDs. The sendAdvancedUssd runs ussd in background and gives you the response as a string. It only surports android 8+(SDK 26+). It defaults to sendAdvancedUssd when the SDK is lower. For multisession USSDs, send the request as one, ie;

UssdAdvanced.sendAdvancedUssd(code: "*123*1*4*3#", subscriptionId: -1);

Selecting SimCard

You can select which simcard to use providing subscriptionId. -1: is for default phone setting. Only supports android 6+, and defaults to default if the SDK is lower
