The two networks formally merged back in July under the name Everything Everywhere, now the two networks are about to work together, offering combined coverage for the respective users. But it's not quite so straightforward as it sounds.First up, this isn't an automatic merging, you need to register with Everything Everywhere to get yourself active on both networks. No bad thing, just a couple of minutes of your time. The second is slightly more disappointing - it seems that only 2G voice networks will merge, data will still be single network. Although on the plus side, if you happen to be calling on one network and lose signal, the other network, where possible, will pick it up. It's probably worth registering just for that.According to Tom Alexander, CEO of Everything Everywhere: 'This is the beginning of an ambitious plan to give our customers instant access to whatever they want, wherever they are - instant access to everything everywhere. 'This is the first major consumer benefit of the merger between Orange and T-Mobile, and it delivers an unrivalled and unique experience that no other operator can offer'.It's likely to be the first step in joint network activity, with future plans for you to jump automatically to the network with the strongest coverage and for 3G data networks to work together in a similar way to 2G. The latter planned is for next year, all being well.
