Im planning on travelling, and my carrier at the destination will be airtel. Now im wondering, does the iphone work on this? It may be a dumb question, but my personal experience has shown that vodafone phones have no trouble when a airtel sim card is popped into their phones, and they work withotu any problems. Vodafone also has a network in that country. Will the iphone work on the vodafone network wihtout any problems? Or is it strictly locked to NZ? Thanks. Sorry if this is in the wrong place, im in a hurry.
