For AT based devices, the support for PDU mode is checked with AT+CMGF=?, and if PDU mode is supported, it will be preferred over text mode. At this moment there is no way to force using text mode, but I guess we could have e.g. a udev tag to trigger the modified behavior (e.g. ID_MM_AT_SMS_TEXT_MODE_PREFERRED), as we do for other features (e.g. ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE).
