Whether you're online every day, or just browse the web occasionally, you can select the right amount of data to suit you.
Don't forget, it's not just surfing the internet that uses data - apps, music streaming, watching video clips and playing games all use data as well.
Data usage
Low (100MB to 250MB)
With 100MB included it's just right for a little internet browsing on your phone and email everyday. 250MB allows you that bit extra everyday.
Medium (500MB to 750MB)
This should be enough data allowance if you frequently surf the internet on your mobile and use apps like Facebook and Twitter, download a few songs or watch YouTube clips. We recommend this to more out of your Smartphone, iPhone or BlackBerry. Plus it gives you unlimited public Wi-Fi* (through BT Openzone). giving you access to Wi-Fi hotspots across the country rather than use your data allowance.
High (1GB to 2GB)
This level of data is for people who want to make the very most of their Smartphone, iPhone or BlackBerry. It'd be perfect if you're watching TV shows, playing online games, downloading high quality music, or downloading large email attachments. Plus it gives you unlimited public Wi-Fi* (though BT Openzone) giving you access to Wi-Fi hotspots across the country rather than use your data allowance.
Tethering
Tethering*: connecting your PC or tablet to the internet via your mobile phone.
All our data Bolt Ons will let you tether if your phone has this capability. We won't charge you anything extra, but we'll take any data you use out of your data allowance.
*Excessive usage policy applies to Unlimited Wi-Fi and tethering where applicable.
