According to the Wall Street Journal AT&T are looking for potential companies within Europe that they can buy-out and make their expansion into Europe.
This will allow them to rollout to markets in areas such as the UK, Germany and The Netherlands, one potential company that TechRadar pointed out would of course be EE, who are one of the biggest operators in the UK and are the first to provide 4G LTE, making them perfect for AT&T’s existing business model.
However that might be a long-shot and I doubt Everything Everywhere would actually be willing to sell given they are quite new to the market.
This isn’t the first time the carrier has tried to buyout another carrier however, as in 2011 they attempted to purchase T-Mobile USA for $39 million but where shortly denied on grounds of antitrust.
