Data Boosts temporarily increase your monthly data allowance, helping you avoid additional charges.
You can boost your data any time you want from once-per-month options of 1GB, 2GB, 5GB or any combination, to provide a maximum allowance of 8Gb per calendar month.
If, for example, you've added and used a 1Gb Data Boost your options for the remainder of the calendar month would be 2Gb, 5Gb or 7Gb.
To add a Data boost, from your my.plan dashboard, go to:
