Sometimes there can be battery errors or strip errors that can happen with any meter, which can be a total bummer! While we can help with troubles you may experience pairing your Accu-Chek Guide meter to your smartphone, we cannot troubleshoot meter hardware troubles, unfortunately.
Roche has an amazing team in their Accu-Chek Customer Care center that can help you get your meter or strip error troubles resolved quickly. All you need to do is call their team at 1-800-858-8072. They also have a chat response feature here: Accu-Chek Customer Care Chat
