Follow these steps to use data efficiently when you travel.
Note that many of the instructions here are intended for Windows and Internet Explorer users - but our general advice will still lower your data usage no matter what system and browser you use.
Disconnect when you're not using
Disconnect your modem or data card when you're not using it - you're still using data by keeping the connection open.
Choose 3G only profile
If your modem is switching between 3G and GPRS before you connect, go to Settings menu > Connection > Network type and choose a 3G only profile. This forces the modem or card to connect to 3G broadband in areas where both are available.
Turn off automatic updates
Turn off automatic updates before you roam, as these are data hungry. Just go to Start > Control panel > Security centre > Automatic updates, select 'Turn off automatic updates' and then select 'OK'.
Turn off 'show pictures'
Turn off 'Show pictures' in Internet Explorer. Go to Tools > Internet options > Advanced and untick the 'Show pictures' option. to show an individual picture while you're browsing, just right-click on where it should be in the page (you will see a box and a red 'x' where the picture should be) and click on 'Show picture'.
Download headers only
Set Outlook to only download headers in your emails. Right-click on the 'Connected' icon on the bottom right hand side of your Outlook window, then tick 'Download headers'.
Work offline as much as possible - draft your emails first, then connect and send them all together, and disconnect once you're done.
Send emails as plain text
HTML and rich text emails contain a lot of formatting information and even images that increase the size of each email. Go to Tools > Options > Mail format and in the message format section, select 'Plain text' and click 'Apply'.
Compress files before you send them
When sending files by email, always compress or zip them first - this reduces the size of files and saves on data usage.
