OS versions

I've checked these

• [ X] It happens on a fresh Cordova CLI project as well.
• [ X] I'm waiting for deviceready to fire.
• [ X] My JavaScript has no errors (window.onerror catches nothing).
• [ X] I'm using the latest cordova library, Android SDK, Xcode, etc.

So how can we reproduce this?

Provide the used components versions (cordova, ionic, etc).
async getCallState(): Promise {
return new Promise( (resolve, reject) => {
this.sim.getSimInfo().then(
(output => { alert(JSON.stringify(output)); resolve (output.callState) }),
(error => { reject (error) })
)
})
}

Provide the steps to reproduce the issue.
