Telephone in Egypt

I purchased a phone card to call back to Malaysia at the Nuweiba immigration building for EGP 10. Talked about 1 minutes and 30 seconds, at it costs me EGP 7! Communication in Egypt really expensive. I used my Singapore mobile phone and roamed in Egypt and I was really consent with my phone bill. I really hated 1 insurance agent who called us but didn't want to hanged up the phone even though I told her I am now overseas, until I told her I had no money to chat with her! Really annoyed those insurance agents.
