I have a cell phone now and can receive calls for free. Most people suggest using Skype to call but international calling cards tend to be pretty good too. Please keep in mind that I am GMT +3 hours. Until daylight savings time ends, I am 7 hours ahead of the east coast. After DST ends, it will be +8 hours.
For example
Now: 11 am in NY, 6pm here
after DST ends: 11am in NY, 7pm here
Country code: +255
