What SIM Card do I need to just use and set up a data plan for Blackberry?

I've got hold of a Blackberry Curve 8520. I don't want to use it to make calls, texts etc. Purely for the use of the Blackberry Messaging Service just for a month or two. What SIM card do I need for this and how can I set up the data plan after I have the correct SIM?What SIM Card do I need to just use and set up a data plan for Blackberry?
If the phone is network locked, you can only use it on the network it is locked to. For example, if it is locked to Orange you can only use it on Orange, unless you pay to get it unlocked. If it is not locked, you can use any network sim in it to use BBM. The only exception to this is 3 UK, as it is not a 3g phone, so a 3 sim will not work in it. All UK networks charge 拢5 per month for the Blackberry services, and offer unlimited messaging, email and access to Blackberry app world for the one price.What SIM Card do I need to just use and set up a data plan for Blackberry?
