I usually use Skype to contact my Sponsor. that is the most convenient and economical way. When I was on bus I always contact him on skype and chat to him If he is available online. Replies are also instant.
After few messages to my affiliates i sent my skype user id to them. Then If they have skype facility they normally send invitation to me. it is a very effective way.
As time is very important to me , that is the best way to contact my affiliates
