Got a call on my cell phone from this number, apparently from a business man I've been talking to online. He was to be in London first but then to Nigeria, bought a SIM card for his phone to call me in both locations.  The call he made to me from London didn't show any number but this one did.  Full number is 234-803-8512292.  Resolves to Nigeria and a Mobile carrier.  Other things about the caller, like not knowing the correct time in London, seem like this could be a scam. So far, has not asked for anything.  Reporting in case he does and is scamming others.
