If you, like me, have an o2 broadband (midband, really) modem, made by Huawei, that you want to unlock to use with other services, you can get quite the run around if you Google how to do this. There are many options (and most Huawei models seem to be easily unlocked), that charge from €5 to €15 for a code to unlock, with the most common one appearing to be dc-unlocker.com (deliberately not linked!).
