摘要： In a method for correcting errors occurring in attention (AT) commands of a mobile device, the mobile device includes a first user identity module (UIM) chipset, a second UIM chipset, a buffer and a timer. The method sets a response time for a communication between the first UIM chipset and the second chipset according to an AT command, backups the AT command into the buffer, and counts a communication time using the timer. When the communication time exceeds the response time, the method restarts the first UIM chipset using a watchdog timer and restarts the second UIM chipset by resetting voltage levels of I/O pins of the second UIM chipset. The method further clears the communication data stored in the buffer, reads the AT command from the buffer and resends the AT command to control the first UIM chipset to communicate with the UIM second chipset normally.
