Can someone please help? My galaxy s4 used to be able to accept and send short code text messages for coupons and deals that local stores, redbox and coupons are sent with, and now it just displays "failed" when try to send.. i called verizon and they say they don't have any idea? can someone please help me get this feature back. All the other phones on my plan can recieve and send short codes, just not mine?
