Digital pictures taken with smartphones often have metadata (i.e. date, time, geolocation) associated with the images. When MMS messages are sent using these types of images, the metadata is usually stripped from the picture by the sending carrier.
However, if the metadata is passed to Twilio by the sending carrier, we will preserve the information and pass it along to the intended recipient. Twilio does not modify or manipulate any metadata associated with pictures. If users need to modify or remove the metadata data from incoming images they will need to use a 3rd party service to do this.
