You may find the Shell app slow to open and Pay at Pump won’t work if there is no mobile signal as it requires a 3G or 4G signal.
However, we have free Wi-Fi at many Shell service stations for you to use if the mobile phone signal is too weak to work. This will allow you to use Pay at Pump, toggle on your rewards and register your visit by scanning your barcode at the till.
You'll need to make sure your GPS or location services are enabled.
You can also save your Shell Go+ card to your Wallet in your mobile device, this will allow you to scan your barcode and record your visit even with no mobile signal.
