Hi,
Have you checked out the job websites for the major telecom companies and contractors like NSN ? if you haven't I would suggest you take a look at them as that is the best place to look for all telco related jobs.
Secondly, it might help if you have had experience with tecnologies prevelent in UK as well as 3G. Just keep in mind that UK is a pretty mature market with a high cellular penetration rate and so there is little in the way of rollout activites being undertaken at any given time.
Best of luck
Regards,
Mesam.
