I'm using an iPhone 5S with a 2 degrees prepay SIM and I'm having issues getting 4G, up to date with iOS 8.3. I can get 4G in other places, such as Rotorua, Auckland etc, but not in Papamoa/Mount Maunganui/Tauranga. When at work, down Hewletts Road at the Port end, I get little reception. A couple of bars of 3G, but often have issues loading stuff using data. Away from there, in town and at home in Papamoa, the reception stays at 3G! The 2Degrees coverage map suggests that it shouldn't.
Any ideas to remedy this?
