Moved to 3 network and mobile data very slow with 4g/3g
Hi, I have recently moved to 3 network sim contract from O2 network, since the port i am experiencing very slow mobile data speeds with 4g/3g connection. Using an iPhone 6s and at home i get okay network coverage at 2 bars; however at work with good network coverage I'm also having the same issue. wifi is okay and i have restarted device several times since the port. Any ideas?
