Frequently asked questions

Multiply daily use by the number of days and divide by 1024 for GB. 500 MB a day for 30 days is about 14.6 GB.

Streaming standard-definition video uses about 1 GB per hour, music a fraction of that, and browsing far less. Video is the biggest user.

Use Wi-Fi where possible, lower streaming quality, download for offline use, and restrict background data for apps.

This uses the binary convention where 1 GB equals 1024 MB, common for data allowances and device storage.

The Mobile Data Usage Calculator uses the formula: Total data used = Daily data use × Number of days ÷ 1024. For example, with daily data use of 500 MB and number of days of 30, the total data used is 14.65.
