Communication Methods (voice, text, email)

Handling communication URIs (Uniform resource identifier), also called protocols

tel:425-882-8080- voice call, like a telephone
sms:800-922-0204 - Short Message Service (texting) - email

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.

GrooVe IP
Verizon Messages+
Google Voice
Hangouts dialer Better for group chat
Meetings - Webinars
