i'm wanting a new phone with wifi and a pay monthly deal.

i currently have o2 pay as you go.

i've seen deals for free texts and unlimited data but phone calls for around 100 minutes only.

can anyone help me ?

Just today discovered this web site. It might help.

I've used in this site here http://www.dialaphone.co.uk/ to get my last mobile and it arrived very quickly and in excellent condition.

Hi,
You can have a look at my site
Compare mobile phone deals
We compare every mobile phone deal available online side by side in a (hopefully easy to use way so you're always getting the best value. At the £20 level the most popular phones at the moment are

Xperia X10 Mini
HTC Wildfire
Blackberry Curve 8520

All good phones and of course all have WiFi. Unless you really want Blackberry email probably dismiss the curve. Hard to choose between the other 2 the best deals today are

Free X10 Mini + 100 mins + unlimited texts + 500mb data = £20/month with 12 months free line rental. Saving £240
or on the Wildfire
Free HTC Wildfire + 300 mins + unlimited texts = £20 per month with 11 months free line rental. Saving £220
or
Free HTC Wildfire + 100 mins + 500 texts + data = £20 per month with 7 months free line rental. Saving £140

Deal wise probably a case of deciding if more minutes or data is most important to you. Best way of course would be to walk into your friendly high street mobile phone shop and play with both then go online to buy - as you probably know you won't get the online deals on the high street

Cheers,
Jon
