There are various factors that one needs to take into consideration, when looking at data usage. If one was to take Apple products for example. If the user’s Apple device is i-Cloud enabled and there have been various changes made to the off-line content, it will, by default, update all of this to the i-Cloud storage facility. This is the same with PC users, running Dropbox with default sync settings.
Also take into consideration that most Anti-Virus programs will also update themselves if they detect an active internet connection. (Most PC users have their Windows Update setting under control, but various other applications like Adobe etc. might still download content even before it prompts the user to download the full update package).
Local email client users will also typically use more data when reading mail (Using an application such as Microsoft Outlook, Outlook Express or Mozilla Thunderbird), as with POP ( “Post Office Protocol” – a type of mail service that determines how email is received and managed) the mail gets downloaded before it gets viewed. Exchange and IMAP (Also, both of these determine how mail is received and managed) will update folder changes etc. when it starts to Synchronise on connection. Whereas, when using your web browser to access mail, you view the content on the server, and minimal data transferring takes place.
Best would be to make sure that most of your applications, Anti-Virus etc. are all up to date as far as possible before using a Pre-Paid public Hot Spot. Also, if possible, browse your email using your browser or only download important headers and then select what mail you would like to download to read. Remember with all the active and live content used in email marketing and signatures these days, some emails might be the cause of some frustrating bandwidth usage.
