Yes, all the mobile phone providers use GSM 900/1800 as well as UMTS 2100. Sometimes you will see it as Dual/Automatic/3G depending on the phone.

As long as the handset is unlocked, you can use any SIM card in it. Most mobile companies in the UK will sell you a cheap handset with a SIM and some credit on Pay As You Go/Talk/Use (PAYG). With using a UK SIM, be aware that there are many different tariffs around which offer different rewards so I advise you to shop arround to find the best one for you. If you are over for several months, you could also look at doing a SIM only contract which is a 30 day rolling contract but you would need to pass a credit check for this.
