Question: what can you do with 1gb of mobile data?
Answer: 1GB (or 1024MB) of data lets you send or receive about 1,000 emails and browse the Internet for about 20 hours every month. (This limit relates only to your 1GB mobile data allocation; if you are an 'inclusive mobile broadband customer' you also get 2000 BT Wi-fi wi-fi minutes every month.)
