Hi guys! My father's 520 can't connect to 3G and I can't change between 2G and 3G, the setting is disabled! I tried a factory resetting with no luck! I even installed the 8.1 dev preview hopping that it will be fixed and I got no luck! I bought the phone on amazon.com and it's from EE UK! So I wanted to know if this is a hardware problem or is EE's problem? Thanks for reading this! (I'm from Venezuela and I'm not sure if his carrier is WP-friendly! Maybe that's the problem?)
P.D: I tried with 2 additional sim cards but nothing happened! (Yes, he can browse the web but only in 2G/E)
