So last night my son is trying to send me a MMS of my granddaughter. I have had the Samsung Prevail through Boost for over a week. When he would send the pic, I get an error message stating Transaction Failed HTTP 403 Error Forbidden. I called Boost and they said there are no outages (a guy on Howard Forums says otherwise). They reset my phone and it still didn't solve it. I also can't send pics withoug getting the error. I updated my profile and PRL and still no luck. I was hoping someone else could give me some insight. Text messages work perfect.
