Hi there
Im so glad your pleased with o2. i work for them and im proud to as well. there ethics are genuine and i am not pressured from 'above corporates' to hard sell - its fantastic. i use the simplicity dongle and love it cos i take my laptop everywhere.
anyway, just so you know, if you on payg mobile and want to upgrade your handset, visit o2 and ask them to check your upgrade for prepay discount. you get 50p for every £10 top up saved into a pot and when you purchase your new phone, take the amount off the price. plus, trade an old phone in too for more discount.
regards
claire
