I believe that is an issue with the lib and I've seen that you have posted an issue on Github that is good.

As a temporary workaround, you could override the behavior of hardware back button with JavaScript just before launching the plugin and cancel this after going back to ionic.

Here is the code :

// priority 101 dismiss "Return to previous view" action
var priority = 101;
var deregisterFunction = $ionicPlatform.registerBackButtonAction(backCallback, priority);
sms.send(number, message, options, success, error);


function success () { 
    deregisterBackButton();
    alert('Message sent successfully'); 
};
function error(e) { 
    deregisterBackButton();
    alert('Message Failed:' + e); 
};

function backCallback() {
    // Do nothing
}

function deregisterBackButton() {
    // Timeout to be sure to don't have issue with back trigerring after
    // returning to view
    $timeout(function () {
        //Deregister
        deregisterFunction();
    }, 1000);
}

You need to inject $ionicPlatform and $timeout in the controller or service you use send.
