It wasn’t £35 – it was £20 to get my phone unlocked.
Thanks to the helpful people who pointed out that there are plenty of free ways to unlock the phone that are available on the Internet. Unfortunately, I have a Nokia 6630 (I say unfortunately advisedly) which so far appears to be uncrackable. Nokia won’t even tell the network providers how to unlock the phones – they have to write off to Nokia and get a code sent back to them that’s specific to the phone being unlocked. So it’s £20 or an unusable phone, unfortunately. Still, given that’s less than a month’s line rental, I’m perfectly happy to pay up to be shot of Orange.
The end is in sight.
