Hi, my S4 speeds have recently gone down from 15 to 8 Mbps in the last 7 days, I think I'm not getting DC-HSDPA at the moment.
Last year I had several weeks where on one side of my house I could get regular HSPA+ speeds on the Galaxy S2 (not DC-HSDPA) but on the other (from another cell tower) it dropped down to dial up speeds. Three said there wasn't a problem, but after about 4 weeks the usual speeds returned. I assume there was a problem which was eventually identified & fixed.
I'm not even bothering to contact three at the moment but keeping fingers crossed the DC-HSPA returns or LTE appears.
