Answer 1

Each cell phone company has their own technology. Even though Cingular and T-Mobile uses GSM technology, they both have phones that require sim cards on their back of their phones. However you will not be able to a cingular phone with a T-mobile sim card and vice versa because both of these network uses a different frequencies from each other.
