Buying SMS Credits - Google Checkout

When buying credits for your account it’s important to note that Google checkout has very stringent anti-fraud measures, whilst most transactions will be immediate, occasionally it can take a while longer as Google does extra checking. The implications are that if you are going to send a large campaign (and need to purchase £100 or more worth of credit) give your self plenty of time to allow the transaction to go through, purchase a day or so before you need to use them.
The status of your transaction appears here, if you see anything other than Completed it means that Google is still processing the order.
Google will also send you notifications via email, so please check your inbox and spam accounts.
