I have a ZTE valet from Tracfone. I've tried EVERYTHING, but I can't send or receive photos by text! Why not?
Because text is SMS, Short Message Service. For pictures, audio and videos you need MMS, Multi Media Service, engaged too.
Have a look in the device's settings.
But you also need to know that MMS messages are lo-res, slow, and expensive in terms of your dataplan. Because SMS and MMS
always use
mobile networks! Even if you are well connected to WiFi for everything else, it will send your SMS/MMS to the nearest cell tower. Not to the internet, for free, like instant messaging apps do.
