13.6 AT+CMGR

s

Notes

•Response if AT+CMGR is used to read an empty record index: +CMGR: 0,,0

•Response if AT+CMGR is used to read a non-existent record index: +CMS ERROR: invalid memory index

•The parameters <ra> and <tora> will only be displayed if parameter <ra> of the AT^SSCONF command is set to 1.

•This command can be used only after the SMS data from the SIM have been read successfully for the first time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds depending on the SIM used. While the read process is in progress, an attempt to use any of the SMS read commands will result in ''+CME Error: 14'' (SIM busy)

•We recommend to take advantage of the "^SSIM READY" URC. If enabled with AT^SSET, this URC acknowl- edges to the user that SIM data is accessible after SIM PIN authentication. It will be delivered once the ME has completed reading data from the SIM card.
