How do I know if my device is affected?

• Check your device settings to see if it supports 4G. You can follow our step-by-step guidance on the Check your device page.
• Contact us or visit us in store and we will check your device for you.

Some non-phone devices also connect to the mobile network, such as alarms, trackers, and monitoring equipment. We can help you identify if these are affected.
