As an unlocked smartphone not tied to a specific U.S. carrier's network, the Nexus 4 can run on any compatible carrier, which means T-Mobile or AT&T in the States. That's very limited portability. As for use overseas, most U.S. carriers let you use their locked smartphones abroad on local carriers' networks by swapping the SIM card, so chances are you are already unlocked for foreign access. Also, you can easily get a subsidized smartphone that is unlocked for overseas use.
If you really want to take advantage of the power of Android, you're better off with a Galaxy S III or other high-end model.
