“Jailbreaking" or "rooting" means removing safeguards from a phone, so a wider range of apps can be installed - including unofficial ones. When a device has been jailbroken or rooted, it makes it easier to install apps that haven't been properly screened for malware. This can leave the devices more vulnerable to fraudulent attacks. If we think we detect malware on your mobile, you'll also be prevented from using the app. To keep our customers' personal information safe and secure, we don't allow jailbroken or rooted devices to be used to access the Mobile Banking app. If you want to keep your device jailbroken /rooted, you can still bank on your mobile by accessing Internet Banking through your mobile browser. If in future you decide to reset your phone to its original manufacturer settings, you should then be able to start using the app.
