Who does data rollover and which SIMs have the best deals?

Data rollover: Which networks do it and which has the best deals?

Are you happy with your data rollover? Do you know exactly how much data you can use every month? Or maybe you’re wary of going over your pitiful allowance.

According to research conducted by Sky UK consumers use on average less than half of the mobile data they buy every month, wasting an estimated £2 billion a year.

For a typical monthly contract this can be as much as £50 every year.

So, it’s important to know exactly how much you use and what it might be costing you.

What is data rollover?

Are you making the most of your data rollover and who offers the best deals?

Simply put, operators offer you an agreed amount of data that you can use on your phone each month as part of your contract. Data rollover allow you to take any unused data from one month and use it the following month.

So, if you have a 3GB monthly allowance but only use up 2GB, the remaining 1GB can be rolled over to the following month. This would give you a new allowance of 4GB.

Who offers what?

The major operators have a wide-range of data rollover packages. Here we outline some of their latest offerings.

iD Mobile

iD Mobile was the first network to offer a free data rollover service. It’s available to both new and existing customers on 12-month, 24-month and even one-month SIM-only GoTo plans.

The service includes capping and inclusive EU roaming. And you don’t have to do anything as it is set-up automatically.


O2 launched their data rollover scheme last February and allows any customer who buys additional data through a bolt-on to roll over any unused data to the next month.

Be aware though that, at present the scheme offer is for bolt-ons only and still operates a ‘use it or lose it’ policy for all other customers.

To spice the pot O2 is offering customers 50% extra data for free if they upgrade their existing contract or switch to O2.

Virgin Media

Virgin Media automatically rolls over any unused data and this is free of charge. The rolled-over data will be used first and only then will you start using up your regular monthly allowance.

Virgin Media allows you to change your data plan every month. And using WhatsApp and Facebook Messenger won’t count towards your data use.


Vodafone’s offer only allows you to rollover data from the previous month, preventing you from saving endless data. To rollover data Vodafone customers need to top up to renew their Vodafone Big Value bundle within the 30-day period and any unused data will roll over into the next 30 days.

Vodafone also offers data rollover for its Pay As You Go customers on their Big Value bundle.

Sky Mobile

According to all comparisons Sky Mobile offers the best deal when it comes to data rollover. In particular you can rollover any unused data at the end of each month and store it online for up to three years. That data will be there whenever you want to use it at no extra cost.

It also offers a family bundle whereby members of your family can pool all of their data allowance together into one piggybank and share it whenever someone needs a top-up.
