I also received the following text from vodafone, the link takes you to vodafone corporate home page. Still can’t find any official statement on their website other than what is contained within the forums.

"On 15 June data roaming prices are changing plus some countries will be moved into a different travel zone, for info, click free http://live.vodafone.com/zr/sa1"

I'm still trying to figure out if this is the message informing us of the out of bundle charges except they have either a) delayed until the 15th June or b) realised that they do have to give 30 days notice and therefore moved to the 15th June?

Are we expecting a letter too... or just a single cryptic text message? I'm afraid that by the time we start to receive data usage warning messages, it will be too late to formally object.
