At the moment, I have a pretty bog standard Nokia phone, my network is Tesco mobile. I am incresingly relying on phone more and more to stay in contact with people wether it be through e-mails, social networking sites or traditional texts
Go for a phone with android and at least a 3.7 inch screen to read those e-mails.Tesco have the HTC Widfire S or Samsung Galaxy Ace on special offer at the minute 250 minutes 5000 texts and 500mb internet for £15.The Wildfire S is easy to operate and has good social networking capability and e-mail.
a nokia n8 flipped on it's side automatically brings up a mini qwerty keyboard the width of the horizontal screen. I'm on 02 and find the signal stronger than most other providers, giving good coverage even in poor signal areas where 3, orange and t mobile struggle for others.
