Blackberry - on Pay as you go

Does anybody have any experience of the above?

Im visiting the UK next month for a wedding and i cant use my Blackberry in the UK as it doesn't have international roaming (to get that i need to be on a monthly contract, working legally which Im not, and have to give the phone company a deposit of over 300 quid, which im not prepared to do )

Does anybody know if you get access to Blackberry messenger and Facebook on a PAYG sim, or do you have to have a contract?
I can live without email for a few days, or make use of the wifi on McDonalds but i cant lose BBM. Will be leaving my daughter here as she is doing GCSE's so need to keep in contact with her.

Thanks
