The caller with the number +2348137150187 appears to be from Nigeria, as indicated by the Nigerian flag showing on their number. The lack of a specific name or identification suggests that the caller's identity is anonymous. This, combined with the fact that only the flag is visible, implies that the caller is likely using a personal or private number. Without further information, it's difficult to determine the caller's intentions or purpose, but the anonymity of the call may raise some security concerns.
The only identifiable feature of the caller's number is the display of the Nigerian flag.
