Your renewal date
When you top up your International Sim for the first time, you'll get your inclusive monthly allowance, which will be valid up until midnight of the day before your renewal date - one calendar month later.
On your renewal date, if you've topped up by at least the minimum amount in the last month, you'll get your new inclusive monthly allowance. If you haven't, you won't get a new allowance. If you've got any credit left, you'll still be able to call, text and use data at our standard rates until it's all gone. You'll need to top up the right amount to qualify for another month's allowance. When this happens, your new allowance will be valid up until midnight of the day before your new renewal date - one calendar month later.
The easiest way to add credit is to use auto top-ups, but you can also:
