Find yourself a VPN, there's plenty of free trials from the various sites and/or free services, (but do not use Hola they're scum who sell your bandwidth to botnets), this is a free one I've used in the past:

Once you're sorted with your free trial, launch their VPN app, choose USA (or wherever unlocks on the 22nd Mexico is showing as 22nd right now whilst USA isn't), once it says you're connected go here to check your IP:
