By registering to a mobile service provider, for instance, Verizon, Sprint, AT&T's, T-Mobile etc, we can select a package that comes with a Apple Iphone 3G. The package will come with a new sim card for Apple Iphone 3G. Alternatively, we can also buy a separate Sim Card and insert into the existing Apple Iphone 3G.
