Need some international SMS blackberry help.

[Jelokin1]

So I am in London for 4 months and I need some help. I have a blackberry with a data plan here but International text messages are outrages. I was planning on using google voice but that is not allowed internationally. How can I text my US friends from the UK to their phones. I see tons of apps that require them to download the app, but i dont want that. Bonus points if the app allows me to get a phone number. I am willing to pay for services too.
