Communications are established with a first base station and the communications include first validation information associated with the first base station. Second validation information is obtained and the second validation information is stored in a data structure. The second validation information is associated with a second and valid base station. The first validation information is compared to the second validation information stored in the data structure and it is determined whether the first base station is valid based upon the comparison. When the comparing indicates that the first base station is not valid, a warning is initiated to a user.
