What is Rollover Data?

Rollover data allows you to carry unused data from month to month, and is a great option for those who don’t want to spend big bucks on unlimited data. Canstar Blue explains rollover data and which mobile plans include it.

What is rollover data?

Rollover data is a feature available on some phone plans that lets you keep any unused data from one month and roll it into the next. In this way you don’t lose the data you paid for, making your plan more flexible. It’s like having a little extra data saved up for when you need it.

What are the types of rollover data?

Rollover data generally comes in two main types:

Monthly Rollover: Any unused data from your current billing cycle is carried over to the next. This means you can only use the leftover data within the next billing period.

Unlimited Rollover: Some providers offer unlimited rollover, allowing you to accumulate and keep rolling over your unused data for an extended period, beyond just the next month. This provides more flexibility over an extended timeframe.

The specific type of rollover data offered varies across mobile service providers, so it’s important to check the terms and conditions of your specific plan to understand how rollover data works for your subscription.
