No, you can only have one Big Value Bundle on your account at once. However, if you run out of data, minutes or texts before your Big Value Bundle expires, you can simply renew it early, providing you have enough credit in your account. Please note: any unused allowances won't be carried over if you renew early.
Alternatively, you can buy any Pay as you go extra to get more minutes, texts or data if you run out of your Big Value Bundle allowances while it’s still running. If you don’t, you’ll pay our standard Pay as you go call charges as long as you have credit.
