Missed call from +237?
If you don’t know anyone in Cameroon, be careful with short missed calls from international numbers. “One-ring” scams hope you call back a premium-rate line. Don’t return the call, don’t share codes sent by SMS, and block the number if it keeps calling. A genuine contact will usually leave a message or text.
