What phone?

If your phone can't handle 4G, you need a new phone.

Yes. I was thinking it just might be one on which 4G could be triggered by accessing this or that. Probably not however. Also, 4G is not necessarily a big deal. With my own usage and signal, I notice little difference between the two.
