I always love to use skype because it gives us a huge ability to communicate witb our friends, as we will be able to talk with our friends for free after creating an account with them.
Once we have account we can follow other peoples around the world and can chat with them.
Pros -
. free for videos calling.
. sometime helpful when we need to talk with our friends easily.
Cons -
. no emergancy calling.
. paid for doing voice calling.
. paid for sending meaaage.
Overall I love skype because it give me voice, video and instant messaging features all in one, which is amazing.
