I can't open photos sent to me in a text message.

I am using a UMX Android phone, and have assurance wireless. I am unable to open text photos sent to me. It will say "downloading" but will then give the message "Couldn't download message". I am missing out on all of the photos that my friends and family send me.

Welcome to Android Central! Photo messages are MMS. Does your Assurance Wireless plan in include MMS? If so, make sure your mobile data is turned on, because MMS requires mobile data (not wi-fi or voice signal).
