Going SIM only is an increasingly attractive option at the moment, as we await the next wave of smartphones. The Samsung Galaxy S II and iPhone 5, among others, are expected within the next 3-4(ish) months.
In the meantime, if you predominantly use your phone for data, this little deal could be right up your proverbial street. For just over a fiver each month (£5.11 to be exact) you get 2GB of data.
Calls cost an extra 20.4p per minute, and texts are 10.2p each. Pay for what you use at the end of the month. Of course, you can always use your data to call folk using Skype or Viber instead.
Offer valid till 31 March 2011.
The SIM will only work in a 3G phone.
