How do I check to see if my device will still work?

Try to perform a system test.  Some products have tests buttons to test connectivity.  If your device does not function normally, you may be affected.  If your device does not allow for a system test, find your manufacturer’s information. Call their customer support line to determine if your device will be affected by the shutdown. 

REMINDER: 3G is an issue affecting millions of Americans. Companies are being inundated with support calls, act early to avoid delayed replacement and assistance.
