Some email messages and web pages may have links (different colored text
which may be underlined) which are designed to allow you click on them to
make a telephone call, send a text message or email.
There are applications that let you make calls and send text messages from
devices (desktops, laptops & tablets) without voice modems, which mobile phones have. e.g.
