THE ATT NETWORK IN IOWA CITY, IA IS EXTREMELY UNRELIABLE. DO NOT SIGN UP FOR NEW SERVICE WITH THIS COMPANY AS YOU WILL BE EXTREMELY DISAPPOINTED. BOTH THIER NETWORK AS WELL AS LOCAL REPRESENTATION ARE UNSATISFACTORY. THE NETWORK SIGNAL IS CONSTANTLY LOST, SOS MODE IS CONSTANTLY KEEPING YOU FROM MAKING/RECEIVING CALLS, PLUS THEY'VE BEEN PROMISING 3G IN THIS AREA FOR YEARS AND KEEP DOING SO TIME AND TIME AGAIN WITH OUT DELIVERING.
