I think that everything has changed with the new version.
You must install the list of Cordova plugins :
cordova plugin add cordova-plugin-whitelist
or if you want to keep a link to your config.xml file:
cordova plugin add cordova-plugin-whitelist --save
and that you should add the intent to your config.xml file :
<allow-intent href="mailto:*" /> <allow-intent href="tel:*" />
