Android Question

I have a tracphone ZTE with a pay as you go contract. I have deleted all text messages on my phone. Recently tries to send and receive photos to no avail. All I see on my screen is a thread text message denoting message size with an arrow to download. It never works! I have owned this phone for only a few weeks and I'm already disgusted with it. The model # is Z665C, android version 4.1.1 baseband version P765V20B01. Band class: CDMA/EVDO 800/1900M. Any suggestions?
