I have a Samsung Galaxy S (model number: SCH-I500) and I am trying to turn it into a Straight Talk phone. This phone was given to me and it is a US Cellular phone, this would be ok except where I live in this southern United States has gotten rid of US Cellular towers. So I have been looking for a way to change it and am still working on looking but would love some help. Thank you in advanced to anyone who can help.
