Thumbs down MMS issues

I recently purchased the galaxy note 3 and Ive noticed that majority of the time I am unable to receive my mms messages, I can send them fine but a lot of the time people I conversate with are sending me picture messages that I am not receiving. Theyve resent them several times and still nothing. It doesnt even show downloading or anything. I am able to receive the sms just fine but so far nothing on the mms. I am stock unrooted and using stock mms. Does anyone know what I can do to maybe resolve this issue. Any help would be greatly appreciatted.
