What?

You'll be able to use the same phone number, so you can receive calls without people knowing you are on a different phone. But it won't make the LG look and work like an iPhone. Because it's an LG, not an iPhone.

I suppose if you're in some crazy country like the US that has all sorts of weird bands and frequencies you might want to check the LG supports the same carriers as the iPhone. In a nice normal country like the UK it's not a problem, you swap SIMs as you want.
