iPhone 6 with ATT here. Typically tested at less than 6 - 7Mbps download speed around Seattle/Bellevue area, where my friend with T-Mobile would get some 40 - 50Mbps while testing side by side with me (connected to the same server). I am starting to wonder if there's an issue with my phone. Could anyone with AT&T from Seattle/Bellevue area share your speed here please? Will probably consider switching to T-Mobile if ATT is found significantly slower than T-mo in this area. Thanks guys!
