There may be a problem with the number setting in the SMS center. Enter the SMS menu option-Settings-SMS-Message Center -SIM Card Information Center-Message Center Number-and enter your number. For China Mobile, the number of SMS service center is+861380xxxxx500, where xxxx is the long-distance telephone area code of your area. If it is less than 4 digits, it will be added at the end, for example, Shanghai is 026550. If the central number can't be used, you can consider changing the card.
