Contact Proof, But what if Skype is used?

According to all those who apply for a visa for their Fiance stated that we have to show proof of communication. My question is that since you spend so much money week on phone bills I got fiancee a computer and internet so we can talk over the phone. Doesn’t that affect us? That makes sense back in the day but I don’t think it make sense now becuase phone is quite expensive if you talk alot. My fiance and I skype nearly everyday to save up money for our wedding. Hmmm… time to spend more money to talk with my fiance..
