When in Wellington - the closest 4G to where I live - I find that my iPhone responsiveness falls dramatically.

For example, typing into the search bar in Safari becomes laborious, with repeated pressing being required before a letter is entered. Sometimes opening/closing things takes ages and so on.

I get round it by just switching 4G off.

However, I understood 4G was supposed to be 'better' than 3G and in this case it really isn't.

Have I got a wrong setting somewhere or something, or is this just how it is?
