Why can't I receive pictures on my Lumia 521?

[WPCentral Question]

I can send pictures, but cannot receive them.

Sign up and give us more details! We can only guess with what you've given us?

Well to start...
Do you have an active and working cellular data connection? (probably since you can send)
Does it say something like "get media content"? or do they just not appear

 

[RumoredNow]

If it was on Straight Talk they had a server side error blocking receipt of MMS on WP. It should be fixed now.

If that is not your issue... You will have to join the site so you can reply here with more details about your situation.
