The sendMMI method is used to send an MMI code.


var request = navigator.mozMobileConnection.sendMMI(message);


A string representing an MMI code that can be associated with a USSD request or other RIL functionality.


A DOMRequest object to handle the success or error of the method call.

In cases where the MMI code requires sending an USSD request, the request's success means that the RIL has successfully processed and sent the USSD request to the network. The network reply is reported via the MozMobileConnection.onussdreceived event handler. If the MMI code is not associated with a USSD but with another RIL request, its result, if one is needed, is sent via the returned request's success or error.


Not part of any specification.
