Is £7 still charged just for receiving calls in an O2 Travel destination?

Note, @squint -

XReceiving calls ...does not trigger the daily charge... ...unless voicemail answers the call, at which point O2 Travel is invoked as your phone hands the call off to voicemail.

Disable voicemail before you leave the UK to be sure. Guide: All you need to know about O2 Voicemail 901
