UK carrier O2 will unlock iPhones once subscriber contracts expire, allowing customers to use the Apple device on rival networks. The decision by Telefonica chairman and CEO Matthew Key could preview how carriers respond to the shrinking number of exclusive iPhone contracts.
“Once the iPhone becomes available on other UK networks, we will allow O2 customers to unlock their iPhones, although of course they will still need to honor any outstanding contract period they have,” Key told the Times. “At the end of their contract period, they are entirely free to move to another operator.”
