However there are some tricks of the trade. 

Firstly make sure that some of the more creative types dont get carried away and start attaching their computers to the phones and using the phone as modem – it will cost alot.

Also when people are travelling, the international data roaming charges on Blackberry’s can be expensive.  Therefore make sure that people know how to turn on / off the data roaming so that they keep the costs down.  It probably makes sense for them to check in a few times per day rather than have the data roaming on all the time.

Another function of the Blackberry that has really helped has been the Blackberry Messenger.  This has allowed team members to send quick messages to each other without using SMS (which is comparatively expensive) and without making phone calls (also more expensive).

The last advantage i found using Blackberry’s is that we used the google maps function to help find places when we travel.

The only downside … its not an iPhone!
