Calling phone and sending email (IOS, Android and UWP)

Hi all,

Currently, I am using following code for calling and email features, but it is only working in Android and not working in IOS. Also, I need these features in UWP.

For call:

string phoneno = "1234567890";
Device.OpenUri(new Uri("tel:" + phoneno));

For mail:

string email = "sreejithsree139@gmail.com";
Device.OpenUri(new Uri("mailto:" + email ));

Any package available for this?

Thanks in advance
