A capped service is where you have a limit, in giga bytes, to the amount of information you download within a month. If you reach this limited then there is an extra charge for further giga bytes you use. In comparison, an unlimited service, allows you to surf the internet without worrying about the amount of giga bytes you use, therefore some unlimited services can come with a higher tariff.

To give you some idea of typical download rates, refer to the table below for a guideline. Please note that this is just a guideline to try and help you workout if a capped service is beneficial to you needs.

	2GB	15GB	50GB
Surfing	4 hours a day	12 hours a day	20 hours a day
Email with attachments	30 a week	500 a week	1000 a week
Email without attachments	150 a week	1000 a week	5000 a week
Downloading songs and short video	15 songs or clips a week	50 songs or clips a week	300 songs or clips a week
Listen to online radio	4 hours a week	6 hours a week	50 hours a week

For example, if you surfed the web for 4 hours a day each month, downloaded emails each month which worked out at 150 a week without attachments and 30 a week with attachments, downloaded 15 songs or short video clips each week with a month and listened to on-line radio for 4 hours a week, then you could take advantage of a service with a 2GB cap.
