Data Roaming Tips
Use wifi
[-]If a customer uses a smartphone or a tablet, they must ensure that only essential data related activities on their device are enabled to avoid using large volumes of data. Receiving email, browsing the web, using instant messaging services and other applications should only be activated when necessary to avoid using large volumes of data and accumulating a high bill.
It is also important to note that using a handset to check email, browse the web, use instant messaging or other applications, is not free when roaming regardless of whether these are available for free in South Africa; and will be billed at the applicable Vodafone world rate for data roaming.
Accessing Vodafone Live! is also not free when roaming as it is in South Africa and will also be billed at the applicable Vodafone World rate for data roaming.
Customers should set up their email client to download the header of new emails only. Once they receive the headers of new emails, they can then manually select which emails should be downloaded in full to prevent large downloads. Try to avoid downloading emails with large attachments to prevent high bills.
Streaming video, person to person file sharing or any other type of file download is extremely data intensive and can result in extremely high bills.
When using data roaming on the laptop abroad, customers must remember to disable all automatic download activity which happens in the background, like operating system updates or software/app updates.
Customers should disable their smartphone or tablet from performing automatic app refreshes or automatic software updates when abroad to prevent large data downloads.
When using data roaming, where possible customers must always roam on selected partner networks to qualify for the Super Saver data rate which is lower than the standard data roaming rates in a specific country. Devices should be manually set to only roam on networks which qualify for the Super Saver data rate.
If customers do not want to use data roaming at all, they must turn Data Roaming off on their device: select ‘Settings’ > ‘General’ > ‘Network’ > ‘Data Roaming’ or consult your device manual for more information.[/-]
I do think that Amazon limits 3G roaming use on the new Kindles though.
