Question

I already used Skype To Go to call regular phone phone numbers, but never to call another Skype user. I would use this to call other Skype users over the regular phone network when on the road.

Answer 1

Yes, you can

You can call a friend on Skype for free (however the charge by your mobile phone operator to call your Skype To Go local number may still apply). For a break down of how much a Skype To Go call costs, see How much does it cost to call a Skype To Go number

Answer 2

One way to use it is with iSkoot. It basically allows routing from your mobile -> skype -> (skype out) or (other skype user). There might also be cheaper alternatives to iSkoot.

Answer 3

Yes! check out skype.com

Using Skype to call another person who also has Skype is totally free. Yep, absolutely nothing. Zip. Zero. Zilch.

HTH!
