I myself just ordered a T610 (to upgrade my T68i) on O2 online which comes
with 500 free texts which I think would be useful for you seeing you spend
that much. If you buy via the link www.o2.co.uk/ucas you get ?25 off the
usual ?49.99 and can also trade in for up to ?50 (you only get ?25 for the
T68i, my recommendation is sell it on Ebay for ?50 instead). I'm however
waiting for them to get it in stock before they send it :-(

Another option if you aren't fond of the idea of O2 online is Orange.
www.orange.co.uk in the special deals section for this month they have
something they call "square deal" with a number of free texts etc... Only
thing is the phone will have Orange written everywhere (not as bad as
Vodafone live but still annoying) and the phone will be most likely locked
to Orange. Also their handset cost is more but it depends on the tariff you
choose.

Hope this helps...

O2 offer good value, but their support can only be described as crap.

Problem1: Each time I came to contact them via email, they ignored it. I
always end up having to phone a 50p/min helpline to actually get anything
done. They have completely ignored at least 2 support emails from me, and
for the third one they send me a email a couple of weeks later saying they
had lost my email, and could I resubmit it pelase. Of course i ended up
paying 50p/min to get it sorted

Problem2: The online billing thing simply does not work. According to my
sister who has had O2 online for a while, the facility to see calls from the
next bill is broken

But it does offer great value for money if you text a lot (like me), 500 /
month is not bad, but be aware that you will effectively have to pay per
incident for any kind of support
