who is this? Called my friend at 6 in the morning.

Also had a call from 239200437 to my mobile phone at 9.30 on a sunday morning - missed it and no message left. I dont tend to give out my mobile number except to friends so not sure how they got it or who it is!!

+239200437 called me at 9 pm on a Saturday night. Missed the call, no message left. Did some research on the number, +239 is the international dialling code for Sao Tome and Principe, which is a little republic consisting of two islands, off the coast of western Africa. Not a clue how they would have got my number, it is my work mobile and I don't give the number to ANYONE apart from my customers and work mates.

This number called me, an I can't call him back, the operator says that the number is an non available number.

i got a call from this number 239200437 a few minutes ago, and i can't call back; can anybody help me identify the caller?
