    Welcome to Android Central! What's the exact model number of the phone, and which carrier are you using?

    It looks like that variant only supports one of the two 4G bands that Vodafone New Zealand uses -- Band 3. It may be that the other band (28) is the main one outside major cities.

    Bugger, is there no way to unlock the other band or activate it.

    I don't think so, but if there were, it would probably involve flashing a different firmware (which could introduce more problems).

    That's if the phone has the hardware inside for that band in the first place.

    Think I may have done it, gone into service mode and enabled the correct band. Need to get out of town to test it now

    It could be. Band 3 is 1800MHz, band 28 is 700MHz. the phone has a 700MHz radio set to Bands 12, 17 and 20.

    I've set it for automatic on all, I can only seem to select one band at a time, how do you select multiple bands
