How to send a special character in SMS??

In order to send special characters like { \ [ ] ^ in SMS , character set needs to be set to “CUSTOM”(User defined character set)

AT+CSCS= “CUSTOM”

For example : Send the backslash("") character in SMS.

The Custom To Extended GSM conversion table and the Extended GSM To Custom conversion table can be used to display these kind of special characters.

The character 0x1B must be set in the right place (in the position corresponding to the value of the ASCII code) in the Custom to GSM conversion table.

The ASCII code of \ (backslash) is 0x5C, the character 0x1B must be set at the position 0x5C of the Custom to GSM conversion table. The range of character 0x5C in this table is 92. So to update the table the command AT+WCCS=1,0,92 will be used.

So,issue following sequence of commands to send the backslash("") in SMS:

  1. AT+CSCS=“CUSTOM”
  2. AT+WCCS =1,0,92
  3. AT+CMGS=“phone no”

\ \ \ ctrl+z

Thanks.
