In the UK, mobile handsets are subsidised by the operators so, in order to prevent handsets being connected to a rival mobile network, it is common practice to 'lock' them.

It's also typical for the network operators to offer their loyal customers a new handset about every 12 months. So many parents have a draw full of unused handsets because their off-spring want to use a handset connected to a different network.

It's not actually illegal to 'unlock' a handset - although it is generally frowned upon by the operators themselves. Most UK High Streets have at least one shop offering to unlock handsets for around £20. It is, of course, illegal to tamper with a handset's unique IMEI number.

The INQ went onto the site unlockthatmobile.co.uk and followed the instructions. It involves placing a call to a premium rate telephone number at £1.50 per minute.

We estimated the total call took around five minutes so that's £7.50. Not too bad and more convenient than handing over the handset to a high street retailer.

It might be worth checking that your exact Nokia model is supported before making the call.

That's not to say that unlocking a handset isn't dangerous. Just ask eighteen-year-old Philip Croker.

This Cheltenham based lad asked his Dad how to unlock a Samsung phone. His Dad realised it was stolen, shopped his son and now the boy is doing three years behind bars. µ
