How do I top up my O2 prepaid account?

Topping up an O2 prepaid account is a straightforward process and can be done in a few different ways to suit individual preferences. One of the most common methods is to use an O2 top-up voucher, which can be purchased at various retail stores or online. Simply scratch off the code on the voucher and enter it into your phone by dialing a specific code followed by the number, or by using the My O2 app. Another option is to top up using a debit or credit card online by visiting the official O2 website. This method allows users to add the desired amount directly to their account without needing to go to a store. Additionally, users can set up automatic top-ups to ensure their account always has sufficient balance. For those who prefer mobile technology, the My O2 app also provides an easy way to manage top-ups and monitor account balance.
