__AK__, Sep 4, 2018 : Just seen the 4G+ icon again on my phone today, had it a few times last week, comes and goes. Just managed to keep it long enough for a speed test and the speeds were rubbish. Could this be Three testing or rolling it out? Could we finally be getting even better speeds on Three? Let's see. The 4G+ speeds on o2 & Virgin Mobile are very good, been testing out other carriers in my area to see which is best, but couldn't settle for anything under than all you can eat data.
