The phone number 07418360099 is being used as part of a network of numbers being used to target UK residents. All these numbers are being used to try to entice potential victims to make investments. Of course it is a very bad idea to agree to investment opportunities over the phone with strangers. However the scammers who use these numbers are very convincing and very determined. 

The best way to avoid becoming vulnerable to these scammers is to not answer any calls from them.
