Your anniversary date

This is the date that you first top up, and will be the day that your mobile bundle resets. Here's how it works:

  • You need to top up the minimum amount by this date to get your allowance – we'll send you a reminder text 4 days before
  • If you don't have enough credit, you won't get your allowance until you next top up – this will be your new anniversary date
  • If you don't have enough credit to cover your tariff and Bolt Ons, we'll activate your tariff first
  • If you top up more than you need, you can use the extra credit for things like Bolt Ons and international calls, or save it for next month

Checking your balance

To check your balance, or to find out when you'll move up to a higher allowance:

  • Call 4444 free, then choose option 2 and 2 again
  • Text BALANCE free to 20202

You can switch between our tariffs once a month by:

  • Texting your new tariff code free to 21300
  • Calling 2202 free from your mobile

If you’re part way through your current tariff month, your new tariff will start on your next anniversary date.
