its really easy
pehle to ap ye dekhen k apka mobile kiya mms send krsakta he? isk liye ap apne mobile k features dekhen jo k usk box pe likhe honge ya phr ap apne network k service center pe call krk pata krlen wo batadenge k apka mob capable he k nhi
agr capable hoga to unse kahen k mere no pe mms facility ko on krden,wo apko msg bhejenge jisme settings hongi unhen save kriyega.
then apne mob ki memory me jaen or jo b pic ap ne mms krni ho usko select kren to apk pas khud hi send ka option ajayega then usko jisko send krna ho to krden.
besure k jis no pe ap send kren usk pas mms recieve krne wala mob ho
