Good points JPM. That's why I seek good reasoning on here - I'm useless!
All deals are cross network mins - not much point in same network mins is there?
I've spent hours trawling through websites of the 'big' players looking for deals etc.
There are too many to choose from.
I think the option to stay with O2 with 400 mins and 1000 texts looks good for £30, but I want a different phone and most of the O2 ones don't float my boat.
