Users are warned to practice caution when using certain providers’ 3G bundles on laptops. Some of these do not protect the user against overspending.
The risk of overspending occurs when users are under the false impression that their 3G package is safe to use until the package runs out. This is not necessarily the case. Higher costs can occur when the initial bundle’s capacity is exceeded and a much higher tariff kicks in. The user will then, without knowing, pay the higher tariff.
The risk of overspending is increased by software updating automatically and therefore generating more traffic. To avoid overspending ensure that the settings of your software updates are set to manual.
Another risk 3G users need to be aware of is the excessive cost of data overseas. Wireless in hotels is usually much more affordable than the local service provider’s roaming data options.
Users are strongly advised to limit the amount they want to spend or traffic they want to allow. (All this information can be found on your service provider’s website.) Also activate sms and email notifications when your data bundle is close to its limit. In this instance prepaid data is a considerably safer option.
3G users are encouraged to monitor their traffic and data usage on the 3G control programme, as well as the service provider’s website. Preferably switch off the 3G facility when it’s not being used.
Very valid point Robert! A few guidelines for students to prevent this from happening can be found here – https://stbsp01.stb.sun.ac.za/innov/it/it-help/Wiki%20Pages/NXInetkey%20guidelines.aspx
I would also like to warn students of the risk of overspending on Stellenbosch inetkey. If, for example, applications decide to update themselves during peak times. There is no method in place to manually set your own limit, as such, it is very difficult to avoid accidental overspending.
