My phone is a Nokia N91 on Orange PAYG & a nephew has kindly set it up
to retrieve my email from a Yahoo account.

I hardly ever use the phone for making or receiving calls so PAYG is
cost effective for me but I would like to greatly increase my usage of
email & web browsing. Primarily on the phone itself but can I also
connect it to a laptop & use it as a modem???

Who currently does the best monthly or even PAYG plan suited to my needs ???

My thanx in advance for any advice, I'm totally lost & the nephew (being
young) struggles with the value differance between £30 & £70 a month.
