Topping up and checking your balance
Everything you need to know about topping up and checking your balance.
Checking your data balance
To check your balance, visit the Pay As You Go mobile broadband page.
Enter your mobile broadband number. Your mobile broadband number will be in the pack that came with your sim. Or if you have an Android tablet, you can text NUMBER to 2020. Tick Remember me and then click Sign in.
You’ll be taken to your account summary page. Here you’ll see how much data you’ve got left and when it runs out.
Topping up your data
If you’re on Pay As You Go, turn off wifi and visit the Pay As You Go mobile broadband page.
Enter your mobile broadband number and click sign in. Your mobile broadband number will be in the pack that came with your sim. Or if you have an Android tablet, you can text NUMBER to 2020.
If this is your first top up, you will see the top-up options you can choose from.
We offer two payment choices; one off or auto top-up. The one off lasts for the period of time you purchase and then runs out. You’ll need to come back to the site to top up at that point or before if you’ve used up all the data within the period. Our auto top-up option allows you to set up an ongoing payment that will renew each month for you. However it’s not a contract so you can cancel it at any time. The advantage of this option is that it’s 10% cheaper.
If you’ve topped up before, you will be taken to the My Account page. Underneath your remaining data you’ll see the top-up options.
We accept Visa, Mastercard and American Express. Your card must be registered in the UK. We accept non-UK registered cards, but only for a one-off top-up.
One off Pay As You Go data packages have expiration periods ranging from one day to one year.
When you top up, you can choose the amount of data you want and how long you want it to last. Your data package will start as soon as you pay. It will last until the expiration date, or until it’s used up whichever is sooner. You can check when your data expires by signing in to your account.
If you have data leftover when you top up, it will be queued and only become active when your current data is used up or expires.
Pay As You Go monthly auto top ups last one month or until you’ve used all your data. Unused data does not rollover into the next month.
Buying Bolt Ons
If you have a recurring Pay As You Go plan, you can buy Bolt Ons to keep you going if your data is running low.
Visit the Pay As You Go mobile broadband page. Sign in to your account to see the Bolt On options and choose the one you want.
If you have some data left, your Bolt On will be added once you run out. Your Bolt On will expire when your data plan renews whether you use it or not, so don’t get more data than you need.
Problems with topping up
If your top up didn’t work, call us on 0344 809 0222. We’ll need your mobile broadband number and details of when you made a payment.
If your payment didn’t go through, it might be because you don’t have enough money in your account or your card has expired. Try a different card or call us on 0344 809 0222 with your mobile broadband number.
