DW got a call earlier that she missed from +239 9890135.
I usually google the number to see if there is any info and found loads of Irish mobile phone owners had got the same. Those that answered said it sounded like two women talking in a foreign language and they hung up. Of those that returned the call, some were told it was barred and some got charged about 6 euro for a 30 second call. So if you get a call from similar number (one person reckoned it’s an island near Ghana!) don’t answer it or try to call it back!
