Phone number associated with contact on SMS conversatoin

I'm based in the UK but am travelling abroad at the moment.
I'm trying to continue SMS conversations with friends in the UK while I'm abroad, but i discovered that a few of them are stored in my phonebook as non-international format numbers - i.e. 07xx rather than +447xx
I've changed their addressbook entries, but the SMS messaging application is refusing to pick up the changed number - it carries on using the old 07xx version.
I don't want to have to delete the conversation but is there any other way of fixing this problem? At the moment, replying to messages is a pain in the a**!
