Mobile network Three has confirmed that it will sell all of its phones unlocked, as Ofcom begins a campaign to get other networks to adopt the same practice.

Currently, many mobile handsets are locked to the network from which they are purchased, and will only work when used with that provider. Unlocking allows consumers to switch network provider without having to buy a new handset. It is also used to avoid roaming charges from local SIM cards when traveling abroad.

While many networks allow unlocking through official channels, they often require a charge and have a set period into the contract or after activation in which they will not unlock phones. In addition, the process can take up to 30 calendar days, depending on the provider.

“We want our customers to have the best mobile experience,” said Danny Dixon, Threes director of customer strategy. “Unlocked phones give consumers a choice as to how to use what is on their handset. Wed rather focus on making the services we offer attractive and useful rather than limiting what our customers can do with their phones.

“Were confident in our network and want to provide the best experience to those that purchase their device from us. We feel that this gives flexibility and choice in the hands of the customer, helps the environment, and it has been very well received by consumers across the board.”
