V9 works fine in town but over the first hill-5ks no reception.Have v3 which shows 5 bars where this shows none.Settings are on auto so if anything there I should get it.Tried all combination settings & different sim but no result.Where do I go?

Hello,
Since the v9 works fine in town, then it simply means, it is not receiving any signal from the hill.
It has a weak signal strength and might receive little or no signal at all from the hill. So for hill tops, try using another phone, but for town use, you can use the v9.
The phone is not in any way faulty, it just is not built to receive signals from such heights. If you have the phone checked, you will not detect any fault simply because the phone is not faulty.
Take care and good luck
