NEW: Smart Roamer Booster

(launched 3 July 2017)

About the boosters

The Smart Roamer Booster provides you with 500MB of data to use whilst roaming in the UK, France or the Republic of Ireland.

This brings roaming data charges down to as little as 4p per MB

What about calls and texts?

Every Smart Roamer Booster includes the following benefits whilst roaming in Zones 1, 2 or 3:

Free to receive calls

This means all incoming calls are free, so you won’t incur any additional roaming charges.

Half price outbound calls 

All calls made (to anywhere in the world) whilst roaming in Zones 1, 2 or 3 will be charged at half the standard retail roaming price.

Please see Sure’s website for the current list of the countries included within each Zone. As a guide, Zones 1, 2 and 3 include the majority of Europe, North America, Middle East, Australia and South Africa.

What happens when you run low on, or out of, data:

Sure will send you a text notification when you reach 50%, 80% and 100% of your monthly roaming data allowance. To continue to roam in the UK, France or the Republic of Ireland during the remainder of the month you will need to purchase an additional 500MB Smart Roamer Booster by calling the Sure Customer Service Centre*.

You will, however, still be able to use data in other countries, which will be charged at Sure’s standard roaming rates. The free to receive calls and reduced outbound call rate features when roaming in Zones 1, 2 or 3 will continue to work, even if you have used up your data allowance.

To purchase a Smart Roaming Booster, or if you are a new customer and require further information on our mobile plans, please contact us in store, online or call our Customer Service Centre.

* Please note that any unused data in an existing booster will be lost when moving to a new booster.

Further Information

Smart Roamer Boosters are charged in addition to standard mobile plans. All boosters have an initial 12 month term, after which only one month’s notice is required, should you wish to cancel a booster. The data allowance provided is per calendar month (so expires on the last day of each month) and it is not prorated. Unused data cannot be rolled over to the following month. Outside of the UK, France or the Republic of Ireland, standard roaming rates, policies and usage limits apply.
