When you usually take out a mobile phone contract your payment covers two things: the usage of texts, minutes and data and the handset you're using.
Mobile phone networks are essentially "leasing" the handset to you for a monthly fee. At the end of your contract (usually 12 to 24 months) they hope that you've paid the full cost of the phone. The SIM is just the microchip the phone uses to access the network.
A SIM only contract i sjust a SIM card, this allows you to choose the phone so you're only paying for the part of the contract that covers the network usage and not the more expensive handset.
