Outbound calls
1. If you hear a fast busy signal when you call a number, all cellular circuits may be in use, preventing the call
from going through. Try calling again later.
2. If you hear a fast busy signal every time you call the same number, your number may be blocked by an app.
Try calling from a different number.
Incoming calls
If you have a signal and can make calls, but callers tell you they consistently get a busy signal when calling you,
check that you haven’t blocked their numbers.
