You can sometimes buy pay as you go phones from another operator and then get them unlocked officially (e.g. by the operator) or unofficially (e.g. in shop or using a code bought on, say, eBay) so that they can be used on any network.
Some large consumer electronics/phone shops also sell SIM free/unlocked phones.
Hope this helps.
