If you go to
'Sitefinder' Mobile Phone Base Station Database you can put your postcode in and see the phone masts near you.
There is a Vodafone one between Clayon Street and the M65, a 3/T mobile one on Henry street.
On Victoria Street there are O2, 3 and T mobile ones. The nearest orange one I could spot is on Blackburn road so that might not be very good for you.
Hopefully the 3 one will work for you as I think the price is good for what you get on the pay as you go one.
