How to Send MMS Using MOBITEK Q25 Modem

Note:-

  1. The correct AT commands for sending MMS is saved in “X:\Reports by Trainees\Taufiq\A20-T-30-4G Modem (Q25)\MMS\MMS Script.ini”.
  2. The MMS settings (AT+QMMSCFG=”mmsc”, AT+QMMSCFG=”proxy, etc.) cannot be saved using “AT&W”, the settings must be re-set after modem is rebooted.
  3. Must use QCOM instead of Hyper Terminal to upload image file.
